The effect of selected high pressure processing (HPP) parameters on the sensory attributes and
shelf life of jackfruit bulb packed using vacuum skin (VS) and vacuum nylon (VN) packaging
was studied. The samples were stored at chilled temperature (4°C) for shelf life study. HPP
significantly (p < 0.05) increased the shelf life of VS- and VP-packed jackfruit bulbs to 60 d
during chilled storage. In terms of colour stability during storage, both VS- and VP-packed
HP-treated jackfruit bulbs exhibited no significant differences (p > 0.05) in L*, a*, and b*
values. Also, the VS- and VP-packed HP-treated samples exhibited no significant differences
(p > 0.05) in terms of texture. However, the sensory evaluation carried out among 48 panellists
showed that there were significant differences (p < 0.05) between the untreated and HP-treated jackfruit bulbs. The aforementioned results had proven that HPP treatment of 500 MPa for
5 min could successfully extend the shelf life and retain the physicochemical properties of
jackfruit bulbs, regardless of the types of packaging used.
A young Malay female presented with a bullous eruption as a manifestation of contact allergy to cinnamic aldehyde in cinnamon. The clinical and histological features resembled bullous pemphigoid but immunological markers for pemphigoid were absent. The patient responded to a short course of oral steroids. Contact allergy can mimic pemphigoid.
Phytic acid (PA) has been shown to have positive nutritional benefits. There are also claims that it is able to prevent cancer through its antioxidant capability. This study investigated antioxidant activity and cytotoxic effect of PA extracted from rice bran against selected cancer cell lines (i.e. ovarian, breast and liver cancer).
A nation-wide outbreak of 260 cases of DF/DHF with 1 death occurred in Singapore from Apr-Sept 1986. The outbreak originated from 3 separate foci of transmission at the western, south-eastern and north-eastern parts of the island and then spread to other dengue receptive urban and suburban areas. The morbidity rate was highest in young male Chinese adults between 15 and 24 years of age. The outbreak was rapidly brought under control through destruction of adult Aedes mosquitoes, surveys and source reduction of larval breeding habitats, health education and to a certain extent law enforcement. The Aedes population was high in the main foci of transmission although the overall house index was only 1.1. Other factors which could have precipitated the outbreak included waning herd immunity of the human population and continuous introduction of dengue virus into the country.
