In one carbon reaction, tetrahydrofolate works as cofactor for the synthesis of glycine, serine, methionine, purines and thymidylate. Folate or vitamin B9 is not synthesized in humans therefore plants are the main source of this essential vitamin. Deficiency of vitamin B9 may cause severe health consequences like birth defects, megaloblastic anemia, cardiovascular disorders, cancers, etc. To re...

This study aimed to evaluate some microbiological and physical-chemical characteristics of fermented milk beverages collected at the main supermarkets in Belo Horizonte (MG). 40 samples of the products corresponding to five distinct brands were collected. They were submitted to the following analyses: Most Probable Number (MPN) of total (30oC) and thermal tolerant coliforms (45oC), Salmonella s...

Sorption characteristics of Co which is rather troublesome nuclide from the aspect of low level radioactive waste disposal was studied. By use of ultraviolet-visible spectrophotometer, coexistence of ionic and colloidal cobalts was verified in aqueous solution with pH>7. Column test was carried out with pH=8.75 and it showed that breakthrough curve obtained consists of two types of curves due t...

The dairy industry has important to day-today in human life. Dairy industry involves processing of raw milk into products like milk, butter and cheese, etc., and generates 1 to 3 times the volume of milk produced. Knowledge on the physico-chemical characteristics of dairy wastewater is essential in the design, operation, collection and treatment as well as disposal facilities for the effective ...

Traditional winegrowing areas are located in temperate climate zones and allow to produce grapes only once per year. Tropical wines have been elaborated in India, Thailand, Venezuela and Brazil and present another kind of viticulture, as compared with countries located in temperate climate zones. Northeast of Brazil started wine production twenty six years ago. This region vines can produce two...

This study assessed the physical, chemical, and microbiological characteristics of traditional Maiorchino cheese (Italy) made from raw ewe's milk or from a mixture with goat's milk. Cheese samples from the same batch were analyzed after 20 days and 6, 8, 12, 17 and 24 months of ripening. A decrease in moisture level lead to progressive total solids concentration (fat, total nitrogen, total soli...

Old technologies often attempted to reproduce the native living form and function. Nowadays physics attempts to use biomaterials to perform complex functions that practically are unreal to achieve with use of traditional materials, for example, semiconductors. The main points of the idea are: biological materials are optimized by the process of evolution and, organisms make them by natural way ...

INTRODUCTION Propolis is a sticky material mixed by honeybees to utilize it in protecting their hives from infection by bacteria and fungi. The therapeutic properties of propolis are due to its chemical composition with bio-active compounds; therefore, researchers are interested in studying its chemical constituents and biological properties. The main objective of this study is to determine the...

The demand of milk product is increasing. Among all the milk products chocolate is mostly preferred confectionary product. In the present research the beany flavour of soymilk was reduced to a greater extent by autoclaving and washing. Various combinations of ingredients were tried for preparation of soymilk chocolate. Among the entire formulations sample ‘O’ had excellent appearance, color, gl...
