Wróblewska B., Kaliszewska A. (2012): Cow’s milk proteins immunoreactivity and allergenicity in processed food. Czech J. Food Sci., 30: 211–219. The immunoreactivity and allergenicity of proteins present in processed food (UHT milk, yoghurt, hard cheese, cottage cheese, biscuit, and sausage intended for children) were determined in this study. Proteins were characterised by SDS-PAGE electrophor...

Cotija cheese is an artisanal Mexican cheese produced with raw cow ́s milk. Our objective was to measure the antioxidant and angiotensin converting enzyme (ACE) inhibitory activities of the peptides released during its ripening. For that, Cotija cheeses were ripened 6 months in a chamber at 25 oC without humidity control. Weekly samples were taken to determine acid soluble nitrogen (ASN), non-pr...

Our objective was to determine the effect of heating on the structure of nonfat Mozzarella cheese, and then to relate changes in structure to changes in cheese opacity. Cheese was made according to a direct-acid, stirred-curd procedure. Cheese samples, at 4◦C, were taken on d 1 and placed into glass bottles, which were sealed and heated. Once the cheese reached 10◦C or 50◦C, the bottles were pl...

INTRODUCTION The interstate commerce of unpasteurized fluid milk, also known as raw milk, is illegal in the United States, and intrastate sales are regulated independently by each state. However, U.S. Food and Drug Administration regulations allow the interstate sale of certain types of cheeses made from unpasteurized milk if specific aging requirements are met. We describe characteristics of t...

Ten strains of Geotrichum candidum were studied on a liquid cheese model medium for the production of sulfur compounds which contribute to the aroma of cheeses. The volatile components produced by each cultured strain were extracted by dynamic headspace extractions, separated and quantified by gas chromatography (GC), and identified by GC-mass spectrometry. It was shown that four strains of thi...

Brucella contaminates people with raw milk, raw dairy products and especially with cheese made from raw milk. This study has aimed to detect Brucella abortus and Brucella melitensis in fresh cheese (Coban Cheese, 100-mold), traditional Afyon Tulum Cheese (Aged Skin Bag Cheese) (50-mold) and sheep-lamb tulum (50-mold) samples provided from Afyonkarahisar province. Conventional Culture Method has...

A biosensor for rapid determination of nonsteroidal anti-inflammatory drugs (NSAIDs) is described based on the inhibition of cyclooxygenase enzyme (both isoforms) by NSAIDs. The results show the full validity of the method, which has also been optimized by comparing the inhibition of two enzyme isoforms, COX-1 and COX-2, in the presence of different tested pharmaceutical drugs (diclofenac, napr...

prochymosin is one of the most important aspartic proteinases used as a milk-clotting enzyme in cheese production. in the present investigation we report sequence of cdna encoding goat ( capra hircus ) preprochymosin and compare its nucleotide and deduced amino acid sequences with sequences of other ruminants preprochymosin. as bovine prochymosin, the caprine prochymosin cdna encodes 365 amino ...

The aim of this study was to determine the chemical and microbiological analysis of soya cheese and compare with cow milk cheese and raw soya. Fat content is lower and protein content is higher in soya cheese than cow milk cheese. Moisture, ash, fat, total carbohydrate, total energy, pH, total chlorides and Total solids are significantly higher in cow milk cheese than soya cheese. Cheese yield,...

OBJECTIVE We present two adult and three paediatric patients who had allergic reactions after cheese ingestion and subsequently tolerated cow's milk derivatives. The objective of this study was to determine possible cross-reactivity between different types of cheese. METHODS Skin tests were performed to cow's milk fractions, and prick-prick tests for goat, sheep and cow cheese. Specific IgE t...
