Nitrogen compounds like urea and melamine are known to be commonly used for milk adulteration resulting in undesired intoxication; a well-known example is the Chinese episode occurred in 2008. The development of a rapid, reliable and economic test is of relevance in order to improve adulterated milk identification. Cyclic voltammetry studies using an Au working electrode were performed on adult...

Once it is available, the information on food intake (FI) may enable the development of strategies to intervene, monitor and explore dietary patterns with more sophisticated statistical methods. Thus, the purpose of this study was to document the quantitative dietary characteristics in a probabilistic sample of adults in Niterói in the State of Rio de Janeiro. A 24-hour dietary recall of a typi...

The object of this study was to determine whether oat, buckwheat and whole brown rice flours have a prebiotic effect on Lactobacillus casei, acidophilus (LA5), Bifidobacterium animalis subsp lactis (Bifidobacterium BB-12). In the study, skimmed milk inoculated with above-mentioned bacteria fortified flours. According results, oat stimulated all investigated, whereas flour had no for L. casei.

The consumption of specific functional foods (FF) and some determinants of FF item selection were assessed using a questionnaire administered to 1112 individuals in the Canary Islands (Spain). Food items considered were Milk products: easily digestible milk (or milk low in lactose), milk enriched with vitamins and/or minerals, skimmed milk with soluble fiber, milk with royal jelly, milk with mo...

An objective method for determining the coagulum cutting time is needed to improve consistency and processing efficiency of goats' cheese. A fibre optic sensor was used to measure the backscatter of near-infrared radiation at 880 nm during the coagulation of skimmed goats' milk for the purpose of predicting coagulum cutting time. A randomised block design, replicated three times, was used to te...

BACKGROUND The identification of beverages that promote longer-term fluid retention and maintenance of fluid balance is of real clinical and practical benefit in situations in which free access to fluids is limited or when frequent breaks for urination are not desirable. The postingestion diuretic response is likely to be influenced by several beverage characteristics, including the volume inge...

Casein micelles (CMs) are used as raw material for processed food as well as in a number of technical applications such as blend fabrics, glues and coatings. A fast and cost-effective way of their preparation from skimmed milk is the micro-filtration of milk. During the micro-filtration a porous membrane enables the separation of CMs from smaller milk ingredients such as whey proteins, lactose ...

The main objective of this work is to show a fermentation influence by some associations of two lactic acid bacteria and three bifidobacteria on proteolysis and the antigenicity of sheep milk proteins. This latter freshly collected is skimmed, sterilized and inoculated by a mixed culture. The mixture is homogenized and incubated at 40°C until it is a curd. On these fermented milks previously ly...
