  1. Fulltext Effect of alternative sweetener and carbohydrate polymer mixtures on the physical properties, melting and crystallization behaviour of dark compound chocolate
    Wong KY, Thoo YY, Tan CP, Siow LF
    Food Chem, 2024 Jan 15;431:137118.
    PMID: 37586229 DOI: 10.1016/j.foodchem.2023.137118
    This study aims to evaluate the effect of sucrose replacer mixtures (erythritol, mannitol, or tagatose in combination with inulin or polydextrose) on the crystal morphology, particle size distribution, rheology, melting properties, and fat polymorphism of dark compound chocolate. The result showed that the replacer mixture's hygroscopicity, particle size, and sugar crystal shape might significantly impact dark compound chocolate's rheological and textural properties but had no substantial impact on the melting properties and fat crystallization. Mannitol-containing samples exhibited the highest rheological value, likely related to their high moisture content, small particle size, and elongated crystal shape. Due to the similar specific surface area and comparable D90 value, the sample containing erythritol-polydextrose mixture resulted in a similar (P ≥ 0.05) Casson yield value (46.184 ± 2.45 Pa) compared to the sample containing sucrose (38.348 ± 1.68 Pa). It could be a potential sucrose replacer in the dark compound chocolate.

  2. Detoxification of Sap from Felled Oil Palm Trunks for the Efficient Production of Lactic Acid
    Kunasundari B, Arai T, Sudesh K, Hashim R, Sulaiman O, Stalin NJ, et al.
    Appl Biochem Biotechnol, 2017 Sep;183(1):412-425.
    PMID: 28361245 DOI: 10.1007/s12010-017-2454-z
    The availability of fermentable sugars in high concentrations in the sap of felled oil palm trunks and the thermophilic nature of the recently isolated Bacillus coagulans strain 191 were exploited for lactic acid production under non-sterile conditions. Screening indicated that strain 191 was active toward most sugars including sucrose, which is a major component of sap. Strain 191 catalyzed a moderate conversion of sap sugars to lactic acid (53%) with a productivity of 1.56 g/L/h. Pretreatment of oil palm sap (OPS) using alkaline precipitation improved the sugar fermentability, providing a lactic acid yield of 92% and productivity of 2.64 g/L/h. To better characterize potential inhibitors in the sap, phenolic, organic, and mineral compounds were analyzed using non-treated sap and saps treated with activated charcoal and alkaline precipitation. Phthalic acid, 3,4-dimethoxybenzoic acid, aconitic acid, syringic acid, and ferulic acid were reduced in the sap after treatment. High concentrations of Mg, P, K, and Ca were also precipitated by the alkaline treatment. These results suggest that elimination of excess phenolic and mineral compounds in OPS can improve the fermentation yield. OPS, a non-food resource that is readily available in bulk quantities from plantation sites, is a promising source for lactic acid production.

    MyJurnal
    This study was designed to elucidate the effects of osmotic dehydration of pumpkin slice prior to hot-air drying. Response Surface Methodology (RSM) with Central Composite Design was used to investigate the influence of three variables, namely sucrose concentration (30-60˚Brix), immersion temperature (35-65˚C) and immersion time (90-120 min). These factors increased the solid gains and decreased the water activity (aw) of the sample; while the temperature and sucrose solution concentration increased the water loss (p

  4. Performance of Malaysian kenaf Hibiscus cannabinus callus biomass and exopolysaccharide production in a novel liquid culture
    'Aizat Norhisham D, Md Saad N, Ahmad Usuldin SR, Vayabari DAG, Ilham Z, Ibrahim MF, et al.
    Bioengineered, 2023 Dec;14(1):2262203.

    The versatility of a well-known fibrous crop, Hibiscus cannabinus (kenaf) is still relatively new to many. Kenaf's potential applications, which can be extended even into critical industries such as pharmaceutical and food industries, have always been overshadowed by its traditionally grown fiber. Therefore, this study aimed to venture into the biotechnological approach in reaping the benefits of kenaf through plant cell suspension culture to maximize the production of kenaf callus biomass (KCB) and exopolysaccharide (EPS), which is deemed to be more sustainable. A growth curve was established which indicates that cultivating kenaf callus in suspension culture for 22 days gives the highest KCB (9.09 ± 1.2 g/L) and EPS (1.1 ± 0.02 g/L). Using response surface methodology (RSM), it was found that sucrose concentration, agitation speed, and naphthalene acetic acid (NAA) concentration can affect the production of KCB and EPS significantly (p

  6. Cryopreservation of Brassidium Shooting Star orchid using the PVS3 method supported with preliminary histological analysis
    Mubbarakh SA, Rahmah S, Rahman ZA, Sah NN, Subramaniam S
    Appl Biochem Biotechnol, 2014 Jan;172(2):1131-45.
    PMID: 24146369 DOI: 10.1007/s12010-013-0597-0
    Cryopreservation is an alternative, safe, and cost-effective method for long-term plant genetic resource conservation. This study was conducted to optimize the conditions for cryopreserving the protocorm-like bodies (PLBs) of Brassidium Shooting Star orchid with the PVS3 vitrification method. Five parameters were assessed in this study: PLB size, sucrose concentration, preculture duration, PVS3 duration, and unloading duration. The viability of the cryopreserved PLBs was determined using the triphenytetrazolium chloride assay and growth recovery assessments. The optimum condition for the cryopreservation of the PLBs of Brassidium Shooting Star orchid is based on the size range between 3 and 4 mm precultured with half-strength semi-solid MS media supplemented with 0.25 M sucrose for 24 h, followed by treatment with loading solution mixture of 2 M glycerol and 0.4 M sucrose supplemented with half-strength liquid MS media at 25 °C for 20 min. The PLBs were then dehydrated with PVS3 at 0 °C for 20 min prior to immersion in liquid nitrogen; finally, the PLBs were immersed with half-strength liquid MS media supplemented with 1.2 M sucrose for 30 min. Histological analyses displayed denser cytoplasm and voluminous nucleus in the cryopreserved PLBs of Brassidium Shooting Star orchid.

  7. An analysis of sugar content of commonly used pediatric liquid medicines--its relevance to dentistry
    Nik-Hussein NN, Razak IA, Karim MN
    Singapore Dent J, 1988 Dec;13(1):24-6.
    PMID: 3154999
    The sugar content of twenty-four liquid medicines commonly prescribed for infants and young children were measured and the type of sugars present were also identified in four randomly selected samples. All the liquid medicines tested contained sugar, in the range of 29.4% to 61.2%. Sucrose appeared to be the most commonly used sugar. Whilst it is agreed that sucrose makes the medicine more acceptable to children, its continual use by the pharmaceutical industry should be discontinued due to its harmful effect on the dental health of children, particularly those taking these syrup-based medicines on prolonged basis. Sugar-free alternatives such as sorbitol or saccharin should be used instead.

  8. Mixed surfactant systems of sucrose esters and lecithin as a synergistic approach for oil structuring
    Bin Sintang MD, Danthine S, Patel AR, Rimaux T, Van De Walle D, Dewettinck K
    J Colloid Interface Sci, 2017 Oct 15;504:387-396.
    PMID: 28586736 DOI: 10.1016/j.jcis.2017.05.114
    In order to modify the self-assembly of sucrose esters (SEs) in sunflower oil, we added sunflower lecithin (SFL) as co-surfactant. It is hypothesized that SFL modifies the self-assembly of SEs by interrupting the extensive hydrogen bonding between SEs monomers. The addition of SFL into SEs induced gelation of the mixed surfactant system oleogels at all studied ratios. The 7:3 SEs:SFL combination showed enhanced rheological properties compared to the other studied ratios, which suggests better molecular ordering induced by SFL. The modifications might have been caused by interference in the hydrogen bonding, connecting the polar heads of SEs molecules in the presence of SFL. This effect was confirmed by thermal behavior and small angle X-ray diffraction (SAXD) analysis. From the crystallization and melting analyses, it was shown that the peak temperature, shape and enthalpy decreased as the SFL ratio increases. Meanwhile, the bi-component oleogels exhibited new peaks in the SAXD profile, which imply a self-assembly modification. The microscopic study through polarized and electrons revealed a change in the structure. Therefore, it can be concluded that a synergistic effect between SEs and SFL, more particularly at 7:3 ratio, towards sunflower oil structuring could be obtained. These findings shed light for greater applications of SEs as structuring and carrier agent in foods and pharmaceutical.

  10. Fulltext Effects of partial sugar replacement on the physicochemical and sensory properties of low sugar cookies
    Ho, L. H., Pulsawat, M. M.
    International Food Research Journal, 2020;27(3):557-567.
    MyJurnal
    The aim of the present work was to produce low sugar cookies by partial substitution with a
    sugar replacer (i.e. maltitol, sorbitol, and isomalt) for sucrose. Four different types of cookies
    were prepared. Sucrose was replaced by maltitol, sorbitol, and isomalt at 50% level (based on
    relative degree of sweetness of sucrose) to produce CMAL50, CSOR50, and CISO50, respectively. Cookies that contained sucrose represented the control. All the cookies produced were
    analysed for chemical properties, physical properties, and sensorial acceptance. The chemical
    analysis results indicated that CMAL50, CSOR50, and CISO50 had higher moisture, crude
    fibre, and the total carbohydrate content, but with lower ash, crude protein, crude fat, calories,
    and total sugar content than the control. CSOR50 showed the lowest total sugar content; thus,
    could be denoted as ‘low sugar’ cookies. Cookies containing maltitol and isomalt presented
    good physical quality. The hardness value of cookies decreased with 50% substitution of
    sorbitol and isomalt for sucrose. CISO50 showed the lowest lightness and yellowness values
    than other cookie samples. The sensory evaluation results showed that the cookies incorporated with maltitol and isomalt did not influence the overall acceptability of cookies. In conclusion, the replacement of sucrose with maltitol, sorbitol, and isomalt could reduce sugar and
    daily calorie intake. However, sorbitol substitution at 50% level is feasible to produce ‘low
    sugar’ cookies, and this cookie could provide benefits to weight and health-conscious
    consumers.

  11. Fulltext Fermentation of black tea broth (Kombucha): I. effects of sucrose concentration and fermentation time on the yield of microbial cellulose
    Goh, W.N., Rosma, A., Kaur, B., Fazilah, A., Karim, A.A., Rajeev Bhat

    MyJurnal
    The yield and properties of cellulose produced from bacterial fermentation of black tea broth (known as Kombucha) were investigated in this study. The tea broth was fermented naturally over a period of up to 8 days in the presence of sucrose. Tea broth with a sucrose concentration of 90 g/l produced highest yield of bacterial cellulose (66.9%). The thickness and yield of bacterial cellulose increased with fermentation time. The bacterial cellulose production increased correspondingly with increased surface area:depth ratio. Changes in pH were related to the symbiotic metabolic activities of yeasts and acetic acid bacteria, and the counts of both of these in the tea broths were relatively higher than those in the cellulose layer. Findings from this study suggest that the yield of cellulose depends on many factors that need to be optimized to achieve maximum yield.

    Response Surface Methodology (RSM) with Central Composite Rotatable Design (CCRD) was performed in this study to develop an acceptable reduced calorie chocolate cake. The range of the independent variables, namely Jackfruit Seed (JFS) flour (20-25% replacement of wheat flour) and polydextrose (10-15% replacement of sucrose) were identified which affect the volume, specific volume, symmetry and uniformity of the chocolate cake. The coefficient of determination, R2 values for volume, specific volume, symmetry and uniformity were greater than 0.900. The optimum level for replacement of sugar with polydextrose was at 11% and wheat flour with JFS flour was at 16% with calorie reduction approximately 34% from the control cake formulation.

    The effects of different types of low-sweetness sugar (lactitol, maltodexrin, palatinit, polydextrose,
    trehalose) on the physicochemical properties of threadfin bream (Nemipterus spp.) surimi during six months of frozen storage were investigated. The characteristics analyzed were moisture content, pH, water-holding capacity, whiteness, folding test, gel strength, expressible moisture, and texture profile analyses. Generally, the cryoprotective effectiveness decreased as the storage time increased. Polydextrose was able to maintain a water-holding capacity of 77.0%, 98.6% whiteness, a folding test value of 100%, and a gel strength of 53.6% compared with its initial value during six months of frozen storage. Meanwhile, sucrose was able to maintain a water-holding capacity of 80.3%, 98.6% whiteness, a folding test value of 75%, and a gel strength of 56.8%
    compared with its initial value. Raw surimi was able to maintain water holding capacity of 62.2%, 98.7% whiteness, a folding test value of 75%, and a gel strength of 36.0% compared with its initial value. It is suggested that, polydextrose as a potential alternative cryoprotectant to replace other low-sweetness sugars.

    Mohammed Salisu Musa, Mohd Marsin Sanagi, Wan Aini Wan Ibrahim, Hadi Nur
    Sains Malaysiana, 2015;44:613-618.
    Carbon spheres (CSs) were synthesized from sucrose by hydrothermal reaction. The synthesized materials were further
    activated with potassium hydroxide (KOH) at different concentrations. The effects of KOH concentration on the surface area
    and morphology were investigated. The route for pore formation and structural deformation in carbon spheres during
    activation has been proposed and discussed based on micrographs and porosity trends. It was suggested that the pore
    formation and structural deformation phenomena were due to the intercalating power of energized K+ into the carbon.
    This work provides an insight of the pore formation in carbon spheres for the development of adsorbents as well as for
    the understanding of the structural deformation of such materials at higher KOH concentrations.

    Sains Malaysiana, 2012;41:1543-1548.
    The effects of various concentrations of honey and sucrose on the longevity and fecundity of Apanteles metesae (Nixon), an endoparasitoid of oil palm bagworm, Metisa plana (Walker) (Lepidoptera: Psychidae) were studied in the laboratory. Our results showed that there were a significant difference (p<0.05) in the longevity of A. metesae fed on various concentrations of honey solutions. Longevity of A. metesae was significantly longer when fed on 50% honey than on pure honey. Nonetheless, longevity of A. metesae females when fed on 50% honey was relatively longer than other honey concentrations. The parasitoid lived significantly longer when fed on 20% sucrose than fed on 50% sucrose and distilled water. However, the parasitoid fed on 50% honey had a longevity that was statistically similar to 20% sucrose and 50% sucrose. Fecundity of A. metesae differed significantly (p<0.05) when fed on 50% honey, 20% sucrose and 50% sucrose. The highest and lowest fecundity was when the parasitoids fed on 20% sucrose and distilled water, respectively. Overall, the result showed that 20% sucrose was a more suitable diet for A. metesae females as compared with other diets.

  16. Fulltext Effects of Selected Physicochemical Parameters on Zerumbone Production of Zingiber zerumbet Smith Cell Suspension Culture
    Jalil M, Annuar MS, Tan BC, Khalid N
    Evid Based Complement Alternat Med, 2015;2015:757514.
    PMID: 25767555 DOI: 10.1155/2015/757514
    Zingiber zerumbet Smith is an important herb that contains bioactive phytomedicinal compound, zerumbone. To enhance cell growth and production of this useful compound, we investigated the growth conditions of cell suspension culture. Embryogenic callus generated from shoot bud was used to initiate cell suspension culture. The highest specific growth rate of cells was recorded when it was cultured in liquid Murashige and Skoog basal medium containing 3% sucrose with pH 5.7 and incubated under continuous shaking condition of 70 rpm for 16 h light and 8 h dark cycle at 24°C. Our results also revealed that the type of carbohydrate substrate, light regime, agitation speed, and incubation temperature could affect the production of zerumbone. Although the zerumbone produced in this study was not abundant compared to rhizome of Z. zerumbet, the possibility of producing zerumbone during early stage could serve as a model for subsequent improvement.

  17. Fulltext Effects of propylene glycol alginate and sucrose esters on the physicochemical properties of modified starch-stabilized beverage emulsions
    Cheong KW, Mirhosseini H, Hamid NS, Osman A, Basri M, Tan CP
    Molecules, 2014 Jun 24;19(6):8691-706.
    PMID: 24962400 DOI: 10.3390/molecules19068691
    This study was conducted to investigate the effect of main emulsion components namely, modified starch, propylene glycol alginate (PGA), sucrose laurate and sucrose stearate on creaming index, cloudiness, average droplet size and conductivity of soursop beverage emulsions. Generally, the use of different emulsifiers or a mixture of emulsifiers has a significant (p < 0.05) effect on the response variables studied. The addition of PGA had a significant (p < 0.05) effect on the creaming index at 55 °C, while PGA-stabilized (PGA1) emulsions showed low creaming stability at both 25 °C and 55 °C. Conversely, the utilization of PGA either as a mixture or sole emulsifier, showed significantly (p < 0.05) higher cloudiness, as larger average droplet size will affect the refractive index of the oil and aqueous phases. Additionally, the cloudiness was directly proportional to the mean droplet size of the dispersed phase. The inclusion of PGA into the formulation could have disrupted the properties of the interfacial film, thus resulting in larger droplet size. While unadsorbed ionized PGA could have contributed to higher conductivity of emulsions prepared at low pH. Generally, emulsions prepared using sucrose monoesters or as a mixture with modified starch emulsions have significantly (p < 0.05) lower creaming index and conductivity values, but higher cloudiness and average droplet size.

  18. Fulltext Effects of selected polysorbate and sucrose ester emulsifiers on the physicochemical properties of astaxanthin nanodispersions
    Anarjan N, Tan CP
    Molecules, 2013 Jan 09;18(1):768-77.
    PMID: 23303336 DOI: 10.3390/molecules18010768
    The effects of selected nonionic emulsifiers on the physicochemical characteristics of astaxanthin nanodispersions produced by an emulsification/evaporation technique were studied. The emulsifiers used were polysorbates (Polysorbate 20, Polysorbate 40, Polysorbate 60 and Polysorbate 80) and sucrose esters of fatty acids (sucrose laurate, palmitate, stearate and oleate). The mean particle diameters of the nanodispersions ranged from 70 nm to 150 nm, depending on the emulsifier used. In the prepared nanodispersions, the astaxanthin particle diameter decreased with increasing emulsifier hydrophilicity and decreasing carbon number of the fatty acid in the emulsifier structure. Astaxanthin nanodispersions with the smallest particle diameters were produced with Polysorbate 20 and sucrose laurate among the polysorbates and the sucrose esters, respectively. We also found that the Polysorbate 80- and sucrose oleate-stabilized nanodispersions had the highest astaxanthin losses (i.e., the lowest astaxanthin contents in the final products) among the nanodispersions. This work demonstrated the importance of emulsifier type in determining the physicochemical characteristics of astaxanthin nano-dispersions.

  20. Benefits of sucrose octasulfate (TLC-NOSF) dressings in the treatment of chronic wounds: a systematic review
    Nair H, Venkateshwaran N, Seetharaman S S, Deng W, Uthaipaisanwong A, Galea E
    J Wound Care, 2021 Apr 01;30(Sup4):S42-S52.
    PMID: 33856929 DOI: 10.12968/jowc.2021.30.Sup4.S42
    OBJECTIVE: Management of chronic wounds remains one of the major challenges for health professionals and patients. An evidence-based decision is important to ensure that patients are receiving the best treatment proven to reduce healing time and improve outcomes, including economic benefits and patients' health-related quality of life (HRQoL). Due to recent restrictions because of the COVID-19 pandemic, including closure of wound care centres within hospitals and a drop in patient volume, chronic wound management needs simple-to-use dressings which are still effective and evidence-based solutions. This systematic review was conducted to identify the clinical evidence available on a sucrose octasulfate dressing (TLC-NOSF, UrgoStart dressing range, Laboratoires Urgo, France) to explore its efficacy in the management of chronic wounds, particularly lower limb ulcers, diabetic foot ulcers and pressure ulcers.

    METHOD: A literature search of PubMed, Cochrane Library and Google Scholar was conducted based on the PICO model (patient/population, intervention, comparison and outcomes) to retrieve publications of different levels of evidence in order to evaluate outcomes of the use of TLC-NOSF dressings.

    RESULTS: A total of 21 publications of different levels, ranging from double-blind randomised control trials to case reports, involving over 12,000 patients, were identified through PubMed, with a further eight publications through Google Scholar and two publications through Cochrane Library. A total of seven results were omitted due to the lack of relevance or repetition.

    CONCLUSION: All the evidence provided suggest that these dressings provide clinicians with an evidence-based option for the management of chronic wounds; that the TLC-NOSF dressings are beneficial in promoting the healing process, reducing healing times, enhancing patients' HRQoL, and in allowing a more cost-effective procedure.
