Cellulose nanofibers have been extracted from arecanut palm sheath fibers via mild oxalic acid hydrolysis coupled with steam explosion technique. Cellulose nanofibers with diameter of 20.23 nm were obtained from arecanut palm sheath fibers. A series of robust hydrophobic cellulose nanopapers were fabricated by combining the synergistic effect of surface roughness induced by the successful deposition of zinc oxide (ZnO) nanoflakes and stearic acid modification via a simple and cost-effective method. In this work, agro-waste arecanut palm sheath was employed as a novel source for the extraction of cellulose nanofibers. 2 wt% of ZnO nanoflakes and 1 M concentration of stearic acid were used to fabricate mechanically robust hydrophobic cellulose nanopapers with a water contact angle (WCA) of 134°. During the deposition of zinc oxide nanoflakes on the CNP for inducing surface roughness, a hydrogen bonding interaction is formed between the hydroxyl groups of cellulose nanofibers and the zinc oxide nanoflakes. When this surface roughened CNP was dipped in stearic acid solution. The hydroxyl groups in zinc oxide nanoflakes undergoes esterification reaction with carboxyl groups in stearic acid solution forming an insoluble stearate layer and thus inducing hydrophobicity on CNP. The fabricated hydrophobic cellulose nanopaper displayed a tensile strength of 22.4 MPa and better UV blocking ability which is highly desirable for the sustainable packaging material in the current scenario. Furthermore, the service life of the pristine and modified cellulose nanopapers was predicted using the Arrhenius equation based on the tensile properties obtained during the accelerated ageing studies. The outcome of this study would be broadening the potential applications of hydrophobic and mechanically robust cellulose nanopapers in sustainable packaging applications.

Recent decades have witnessed a surge in research interest in bio-nanocomposite-based packaging materials, but still, a lack of systematic analysis exists in this domain. Bio-based packaging materials pose a sustainable alternative to petroleum-based packaging materials. The current work employs bibliometric analysis to deliver a comprehensive outline on the role of bio nanocomposites in packaging. India, Iran, and China were revealed to be the top three nations actively engaged in this domain in total publications. Islamic Azad University in Iran and Universiti Putra Malaysia in Malaysia are among the world's best institutions in active research and publications in this field. The extensive collaboration between nations and institutions highlights the significance of a holistic approach towards bio-nanocomposite. The National Natural Science Foundation of China is the leading funding body in this field of research. Among authors, Jong whan Rhim secured the topmost citations (2234) in this domain (13 publications). Among journals, Carbohydrate Polymers secured the maximum citation count (4629) from 36 articles; the initial one was published in 2011. Bio nanocomposite is the most frequently used keyword. Researchers and policymakers focussing on sustainable packaging solutions will gain crucial insights on the current research status on packaging solutions using bio-nanocomposites from the conclusions.

The objectives of this study were predicting the transmission and survival of L. monocytogenes in cooked ham during supply chain. Cooked ham are frequently contaminated with L. monocytogenes during postprocessing steps through contact on surface of processing, handling, packaging equipment. Transfer rate of L. monocytogenes on static and dynamic condition in various surface type was investigated. The prevalence and level of L. monocytogenes in cooked ham at plant as well as the prevalence of unsatisfactory processing at retail were studied. A Monte Carlo simulation model was created by using @risk. The simulation predicted that the prevalence was 11.76 % with 90% confidence interval of 2% to 25% and estimated level was -4.02 log CFU/cm2. It was estimated to be occurred on slicing step at plant. Our results suggest that, the prevalence and level of L. monocytogenes can be reduced by Good Handling Process application and/or HACCP application.

As Malaysian economies grow, Malaysian per capita income is likely to increase. From economics point of view, it is expected that better-off consumers will move to better quality of food attributes such as freshness, food safety, quality and healthfulness in their food intake. This study aimed to investigate the demand for eggs attributes by Malaysian consumers. The study considers the conjoint analysis technique as a method for acquiring insights into preferences for eggs product. The technique was applied to establish the trade-offs that Malaysian consumers make between size, colour, size of packaging, functional attribute and price in the purchasing of eggs for 202 respondents. Least squares regression was utilized to estimate the relative importance of attributes for eggs. The results revealed that the ideal characteristic of egg was one with large size (grade A), omega eggs, brown, and ten per packs. We also found that consumers were also willing to pay more for their preferred attributes. The results found in the study provide valuable inputs to producers or marketers to improve their marketing efforts as well as market positioning, in line with the demanded eggs attributes.

In determining consumer’s acceptance of any products in the market, packaging appearance, branding and pricing of the products are important. This study focused on consumer’s perception towards the outlook of the coffee packaging which resulted in influencing their purchasing decision through survey study. This current study was done on three main issues namely appropriateness of appearance, branding and pricing as reflected by the first impression towards the product’s packaging. Survey was done targeting on consumers (n = 100) reside in Kelantan, Malaysia through printed and online questionnaires distribution. Results obtained shows that consumers notice the differences possessed by each coffee packaging in the market and they purchase what they like based on their perception. According to Pearson Correlation, respondents also have the opinion that appearance, branding and pricing are correlated to each other in order to convey the correct messages to the correct group of people (p-value > 0.5). Response from the respondents reflected the behaviour of consumers reside in Kelantan that the overall outlook (packaging appearance, branding and pricing) of a coffee packaging were taken into consideration during their buying process. Therefore, it is crucial for the packaging itself to be able to create emotional attachment in consumers’ mind during their first glimpse.

Nur Hanani ZA, Beatty E, Roos YH, Morris MA, Kerry JP

Foods, 2013 Jan 02;2(1):1-17.
PMID: 28239092 DOI: 10.3390/foods2010001

The objectives of this study were to develop composite films using various gelatin sources with corn oil (CO) incorporation (55.18%) and to investigate the mechanical and physical properties of these films as potential packaging films. There were increases (p < 0.05) in the tensile strength (TS) and puncture strength (PS) of films when the concentration of gelatin increased. The mechanical properties of these films were also improved when compared with films produced without CO. Conversely, the water barrier properties of composite films decreased (p < 0.05) when the concentration of gelatin in composite films increased. Comparing with pure gelatin films, water and oxygen barrier properties of gelatin films decreased when manufactured with the inclusion of CO.

Uncovering environmental performance patterns of plastic packaging waste in high recovery rate countries: An example of EU-27

Fan YV, Čuček L, Si C, Jiang P, Vujanović A, Krajnc D, et al.

Environ Res, 2024 Jan 15;241:117581.
PMID: 37967705 DOI: 10.1016/j.envres.2023.117581

Plastic consumption and its end-of-life management pose a significant environmental footprint and are energy intensive. Waste-to-resources and prevention strategies have been promoted widely in Europe as countermeasures; however, their effectiveness remains uncertain. This study aims to uncover the environmental footprint patterns of the plastics value chain in the European Union Member States (EU-27) through exploratory data analysis with dimension reduction and grouping. Nine variables are assessed, ranging from socioeconomic and demographic to environmental impacts. Three clusters are formed according to the similarity of a range of characteristics (nine), with environmental impacts being identified as the primary influencing variable in determining the clusters. Most countries belong to Cluster 0, consisting of 17 countries in 2014 and 18 countries in 2019. They represent clusters with a relatively low global warming potential (GWP), with an average value of 2.64 t CO2eq/cap in 2014 and 4.01 t CO2eq/cap in 2019. Among all the assessed countries, Denmark showed a significant change when assessed within the traits of EU-27, categorised from Cluster 1 (high GWP) in 2014 to Cluster 0 (low GWP) in 2019. The analysis of plastic packaging waste statistics in 2019 (data released in 2022) shows that, despite an increase in the recovery rate within the EU-27, the GWP has not reduced, suggesting a rebound effect. The GWP tends to increase in correlation with the higher plastic waste amount. In contrast, other environmental impacts, like eutrophication, abiotic and acidification potential, are identified to be mitigated effectively via recovery, suppressing the adverse effects of an increase in plastic waste generation. The five-year interval data analysis identified distinct clusters within a set of patterns, categorising them based on their similarities. The categorisation and managerial insights serve as a foundation for devising a focused mitigation strategy.

A facility layout can be defined as an arrangement of the equipment area in the
industry or organization of the factory. The main objective of this project was to
improve the existing layout in SMEs using DELMIA QUEST simulation. In this
project, new layouts are proposed to reduce the waiting time in a production
line and increase the productivity. This study focused on packaging production
line of a coffee manufacturing company located in Tasek Gelugor Pulau
Pinang. The problems identified in this production line are limited working
space, some processes overlap and are stuck due to high demands of the
products. This results in high lead time. The existing layout was studied and
simulated to improve certain parameters such as labour, machines, and shape
of the layout. The workstations were repositioned in the proposed layout before
undergoing simulation process using DELMIA QUEST software. From the
simulation results, the significant improvement was determined and the best
layout was chosen in terms of machines utilization and total output. Based on
this, a new layout is proposed to increase the productivity capacity and to meet
customers’ demands. Simulation data of the proposed layout showed its
productivity had increased to approximately 41.5%.

Dasan YK, Bhat AH, Ahmad F

Carbohydr Polym, 2017 Feb 10;157:1323-1332.
PMID: 27987839 DOI: 10.1016/j.carbpol.2016.11.012

The current research discusses the development of poly (lactic acid) (PLA) and poly-(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) reinforced nanocrystalline cellulose bionanocomposites. The nanocrystalline cellulose was derived from waste oil palm empty fruit bunch fiber by acid hydrolysis process. The resulting nanocrystalline cellulose suspension was then surface functionalized by TEMPO-mediated oxidation and solvent exchange process. Furthermore, the PLA/PHBV/nanocrystalline cellulose bionanocomposites were produced by solvent casting method. The effect of the addition of nanocrystalline cellulose on structural, morphology, mechanical and barrier properties of bionanocomposites was investigated. The results revealed that the developed bionanocomposites showed improved mechanical properties and decrease in oxygen permeability rate. Therefore, the developed bio-based composite incorporated with an optimal composition of nanocrystalline cellulose exhibits properties as compared to the polymer blend.

Hashim R, How LS, Kumar RN, Sulaiman O

Bioresour Technol, 2005 Nov;96(16):1826-31.
PMID: 16051090

The flame retardancy of medium density fiberboard (MDF) made from mixture of rubberwood fibers and recycled old corrugated containers was studied. Aluminum trihydroxide (ATH) was used as a fire retardant additive and mixed with the fibers to manufacture experimental MDF panels using wet process. Phenol formaldehyde (PF) resin in liquid, 2% based on oven dry weight of fibers, was used along with 0%, 10%, 15% and 20% of ATH. The flame retardant test was done using the limiting oxygen index (LOI) test. The other properties investigated include internal bond strength, thickness swelling and water absorption. The results showed that ATH loading increased as the LOI of MDF increased. This demonstrated that ATH could improved the fire retardant property of MDF at sufficient loading. An increase in concentration of ATH showed an increase in the IB values of MDF made without resin. MDF panels made without resin showed a progressive increase in internal bond as the composition of recycled old corrugated containers fiber increased. Addition of resin improved internal bond strength and reduced thickness swelling, and water absorption. Thickness swelling of panel increased as the composition of recycled old corrugated containers fiber increased. Scanning electron microscopy (SEM) and energy dispersive X-ray analysis (EDAX) showed that there is indication of ATH and resin filling the void space in between fibers.

Fulltext Sodium content in sauces-a major contributor of sodium intake in Malaysia: a cross-sectional survey

Shahar S, You YX, Zainuddin NS, Michael V, Ambak R, Haron H, et al.

BMJ Open, 2019 05 27;9(5):e025068.
PMID: 31133578 DOI: 10.1136/bmjopen-2018-025068

OBJECTIVE: To investigate the sodium content in sauces sold in Malaysian supermarkets.
METHODS: A cross-sectional market survey was conducted in 2017 of 233 sauces sold in Malaysian supermarkets. Information on the sodium content was collected from the product packaging and nutrient information panels of the sauces sold in the seven top supermarkets in the capital of Malaysia.
RESULTS: Of the 233 sauces surveyed, 116 did not include sodium content information on the nutrient information panel (49.8%). Soy sauce (particularly sweet soy sauce) and ketchup (particularly chilli sauce) were found to be the highest number of products surveyed in the analysis (N=54 and N=48, respectively). The highest sodium content information was displayed by fish/prawn sauce (budu/cencalok) (5192±3228 mg/100 g) which was followed by the light/thin soy sauce (5116±2084 mg/100 g), and followed by salty soy sauce (4780±988 mg/100 g). The sodium content information of the imported sauces was higher compared with local products produced in Malaysia. However, for sweet soy sauce, the sodium content information of the local products was higher compared with the imported products. Of the 116 sauces which displayed information regarding their sodium content, only 18.2% of the salty soy sauce and 25% of the light/thin soy sauce were found to be below the 2017 Malaysian sodium guidelines. Furthermore, only 21.7% of chilli ketchup and no tomato ketchup were below the 2017 UK salt guidelines.
CONCLUSIONS: Almost half of the sauces surveyed did not include sodium content information on the nutrient information panel. It is recommended that sodium content information is provided on all sauces sold in Malaysia. Also, manufacturers should be urged to reduce the sodium content level of their sauces to a minimum of 5%.
