چکیده

High hydrostatic pressurization is proposed for cheese ripening acceleration. Several treatments were used for accelerating ripening of goat’s milk cheese: 50 MPa / 72 h, 400 MPa / 5 min and 400 MPa / 5 min followed by 50 MPa / 72 h all at 14 °C. Moisture content and pH were higher in 400 MPa treatments compared to the others. By measuring proteolysis indexes, 400 MPa treatments were found to accelerate ripening (14 d in contrast to 28 d conventionally) due to enhanced enzyme activity from inoculated starter culture. Sensory analysis indicated bitter notes in the accelerated ripened cheese. Pressurized cheeses were less crumbly and more elastic than control.

Investigation on the Protein Degradation, Free Fatty Acid Content and Area Fraction of Poosti Cheese, Iranian Traditional Cheese Ripened in Skin

Background and Objectives: In this study, the proteolysis and lipolysis of Poosti cheese produced from raw sheep milk in mountainous eastern regions of Iran were investigated during 90 days of ripening. Materials and Methods: Sodium dodecyl sulfate polyacrylamide gel electrophoresis for proteolysis (SDS-PAGE) and gas chromatography (GC) for free fatty acids (FFAs) were applied to investigate th...

Dairy Foods: Milk Protein and Enzymes Symposium

Direct addition of enzymes to milk during cheesemaking appears to be the simplest method to accelerate cheese ripening. However, due to loss of most enzymes in whey, poor enzyme distribution, and texture defects by extensive proteolysis, alternative encapsulation technology can eliminate these defects. Previous approaches on the addition of free enzymes during salting stage and encapsulation of...

Proteomic study of proteolysis during ripening of Cheddar cheese made from milk over a lactation cycle.

Milk for cheese production in Ireland is predominantly produced by pasture-fed spring-calving herds. Consequently, there are marked seasonal changes in milk composition, which arise from the interactive lactational, dietary and environmental factors. In this study, Cheddar cheese was manufactured on a laboratory scale from milk taken from a spring calving herd, over a 9-month lactation cycle be...

“Allergy to Goat/Sheep’s Milk with Good Tolerance to Cow’s Milk but Not to Cow’s Milk Cheese: Identification of 1-105 Peptide from κ-Casein as the Molecular Basis of Reactivity toward Cow’s Milk Cheese

In Europe, a new population of patients developing anaphylaxis to goat’s/sheep’s milk associated to tolerance to cow’s milk has recently appeared. Nevertheless, among these patients, some show allergic reactions to cow’s milk cheeses but these reactions are less severe than those directed against goat’s/sheep’s milk. The objective of the study was to the molecular determinants of the reactivity...

High Pressure Processing and its Application in Cheese Manufacturing: A Review

Nowadays, high standard level of living has led to an increase in demand for foods which are minimally processed via high sensory and nutritional quality and also an extended shelf life. High pressure processing (HPP) is one of the techniques that was considered for food preservation at the first application in food industry. Pressures in the range of 300 to 650MPa have been found to affect the...
