background & aim: erosion has been defined as the irreversible loss of dental hard tissue by a chemical process not involving bacteria. dental erosion is an important cause of tooth tissue loss in both children and adults. acids of intrinsic and extrinsic origin (gastric juice and acidic foodstaffs, beverages) are thought to be the main etiologic factors for dental erosion. the reported inciden...

Probiotic organism Bifidobacteria was isolated from the faeces of breast-fed infants at Universiti Putra Malaysia. Trypticase phytone peptone yeast extract agar (TPY) was used as a selective media for the isolation. Morphological examination of the isolates indicated that Bifidobacteria was Gram-positive rods in nature, curved with characteristics of V and Y shapes. The organisms were non-catal...

Statement of the problem: Flavored waters have become increasingly popular in Trinidadian retail market. There is a paucity literature on erosive potential these products dental hard tissue. Purpose: This study 1) evaluated pH and titratable acidity still sparkling flavored marketplace 2) effect time temperature acidity. Materials methods: A calibrated meter was used to measure at baseline (T0)...

Pectin methylesterase (PME) rapidly hydrolyzes pectin methylesters in cold break tomato juice to form methanol and to increase titratable acidity (TA). Within 30 min, the juice methanol concentration increased from 35 to over 400 lg g 1 while the pH dropped from 4.45 to 4.20. On average, cold break juice pH values were 0.21 U lower and TAs 12.4 leq g 1 higher than those for hot break juices pre...

BACKGROUND Yoghurt is a fermented milk of unique sensory, nutritive and dietetic value offered in a variety of types and in different flavours. Vegetables belong to the group of food products rich in antioxidant substances (e.g., vitamin C, carotenoids, tocopherols, polyphenols) which regular consumption lowers the risk of many diseases including cancers and cardiovascular disorders. The aim of...

Temperature integration where high day temperatures are compensated by lower night temperatures is one strategy that can be used to reduce energy consumption in greenhouses. Crop tolerance to temperature variation is a prerequisite for using such a strategy. Greenhouse experiments were conducted on tomatoes cvs, Capricia, Mecano and Cederico in order to investigate the effect of different day/n...
