There is currently much interest in pomegranate juice because of the high content of phenolic compounds. Moreover, the interest in the separation of bioactive compounds from natural sources has remarkably grown. In this work, for the first time, the Punica granatum L. (pomegranate) juice—clarified by using polyvinylidene fluoride (PVDF) and polysulfone (PSU) hollow fiber (HF) membranes prepared...

Information was sought on the cause, effects, and control of dextran in sugar manufacture in Jamaica. Storage experiments on manually harvested, burnt, whole-stalk cane revealed that Leuconostoc mesenteroides was the predominant spoilage organism. Its growth was accompanied by significant increases in dextran content and juice viscosity. However, these parameters. did not increase linearly with...

This study aimed to examine whether daily intake of citrus juice containing heat-killed Lactobacillus plantarum YIT 0132 (LP0132-fermented juice) alleviates symptoms of atopic dermatitis. This was a natural extension of our previous study in which LP0132 was shown to enhance IL-10 production in vitro and LP0132-fermented juice was found to alleviate symptoms and enhance quality of life (QOL) in...

Raw sugar colour is an increasing sugar quality concern, not because of a decline in the quality of South African very high pol raws but rather due to rapid improvements in the raw house colours in the rest of the world. Technically, raw sugar with lower colour has direct implications for the refiner’s effort and cost of processing that sugar. Enormous benefits could be derived if colourants co...

paratus. In activity 2, students can use the equipment used by hobby winemakers – a vinometer – to measure the alcohol content of the must and wine. 3. A well balanced wine needs a certain amount of fruit acid; the total acid content is a very important measure, because it directly affects the flavour. In activity 3, the acid content is determined by pH titration. Four further activitiesw2 can ...

The osmotic dehydration (OD) process consists of the removal of water from a material during which the solids from the osmotic solution are transported to the material by osmosis. This process is commonly performed in sucrose and salt solutions. Taking into account that a relatively high consumption of those substances might have a negative effect on human health, attempts have been made to sea...
