• Abstract

  Milk is considered a food with essential nutrients in the diet, among the milk proteins, ²-casein (²-CN), which has among its most common variants the alleles A1 and A2. ²-Casomorphin-7 is an opioid, product of ²-CN digestion, which is produced up to four times more in the presence of variant A1, and can cause physiological disorders related to the gut-brain axis. Milk from cows with A2A2…

  Analysis of the effect of milk from cows with A1A1 and A2A2 genotypes for beta-casein, biofortified or not, in piglets post weaning, AP.R

• Abstract

  Little is known about the phenotypic characteristics and physical-chemical properties caused by the different genotypes in the milk produced and what may have led to the choice between alleles A1 and A2 for dairy cattle. There are also no reports to date on the performance of microbial proteases in milk produced by animals with the A2A2 genotype. The scientific community still does not fu…

  Protein profile and milk proteome with contrasting genotypes for the ²-casein gene and verification of the proteolytic action of Bacillus cereus s.s. and Pseudomonas fluorescens and technological treatments applied to milk on the production of BCM7, AP.R

• Abstract

  Bacillus cereus is an important bacterium related to the milk supply chain in Brazil and in other countries, because it causes technological spoilage to dairy industries due the production of proteases and lipases, and also it can be a risk to public health due the production of toxins that can cause diarrhea and emesis. This bacterium also is able to survive to various heat treatments ap…

  Bacillus cereus impact in dairy supply chain: gene expression related to gastroenteric toxins, spoilage enzymes during the shelf-life of pasteurized milk and determination of disinfectants efficacy on biofilms, AP.R

• Abstract

  Among milk proteins, caseins are the majority, in which ²-casein is the largest participant. This protein can be presented in several variants, with A1 and A2 being the most common in a dairy herd. The casein micelles are made of ± and ²-casein in its interior and º-casein on the outside, as a protection. Enzyme action upon º-casein is able to separate its two subunits, giving rise to the…

  Microbial proteases action on milk from animals with A1 and A2 alleles for ²-CN, BP.IC

• Abstract

  Little is known about the phenotypic characteristics and physical-chemical properties caused by the different genotypes in milk. The scientific community still does not fully agree on the benefits of A2 milk consumption, compared to A1. The present project aims to identify possible genotypic and phenotypic effects in cows with alleles A1 and A2 of ²-casein. In addition, it intends to eval…

  Genotypic, phenotypic and milk composition study of cows with alleles A1 and A2 of Beta-Casein, BP.MS

• Abstract

  The Bacillus Cereus is a bacterium that has enzymatic action and not only can lead to technological problems in the milk production chain but also is a threat to public health once it produces toxins that can cause a diarrheal syndrome. Such bacteria have the characteristic of being resistant to many thermal treatments used in the processing of milk and derivatives in addition to synthesi…
