This review paper aimed to provides precious information about the function and use of different enzymes in dairy food applications. An enzyme is called a protein and catalyzes a specific reaction. Every enzyme is intended to initiate a particular reaction with a specific outcome. Moreover, numerous enzymes are present in the human body. Dairy food applications include the use of different enzy...

Abstract The primary objective of our study was to detect the occurrence enterotoxigenic Staphylococcus aureus in diverse types cheese (cow’s milk and mixed cheese) samples from R.N. Macedonia. Cheese were analyzed for enumeration isolation S. strains according ISO 6888-1. We detected toxigenic potential by use Enzyme Link Fluorescent Assay VIDAS system, we confirmed presence SEs ( sea, seb, se...

To accelerate cheese ripening, enhance its flavor types and intensity and make cheese flavoring agent in shorter time, surface ripening bacterium (Brevibacterium linens and Debaryomyces hansenii) and/or enzymes (Flavorzyme 500 MG and Palatase 20000 L) were used in cheese curd. In this study, aroma compounds generated by using ripening cultures and/or enzymes were analyzed. The control l was mad...

Three hundred and ninety-three samples of dairy products (124 samples of white cheese, 61 samples of cream cheese, 76 samples of Kashar cheese, and 132 samples of butter), 91 samples of cashew nut and 97 macademia nut marketed in Eastern Province, Saudi Arabia during September 2010-September 2011, were analyzed for aflatoxin M1 (AFM1), total aflatoxin and AFB1 by microtitre plate enzyme linked ...

Bacterial metabolism of Tyr and Phe has been associated with the formation of aromatic compounds that impart barny-utensil and floral off-flavors in cheese. In an effort to identify possible mechanisms for the origin of these compounds in Cheddar cheese, we investigated Tyr and Phe catabolism by Lactobacillus casei and Lactobacillus helveticus cheese flavor adjuncts under simulated Cheddar chee...

A fluorescence method to monitor lysis of cheese starter bacteria using dual staining with the LIVE/DEAD BacLight bacterial viability kit is described. This kit combines membrane-permeant green fluorescent nucleic acid dye SYTO 9 and membrane-impermeant red fluorescent nucleic acid dye propidium iodide (PI), staining damaged membrane cells fluorescent red and intact cells fluorescent green. For...

Physicochemical properties (partition and diffusion coefficients) involved in the mobility and release of salt and aroma compounds in model cheeses were determined in this study. The values of NaCl water/product partition coefficients highlighted interactions between proteins and NaCl. However, these interactions were not modified by the product composition or structure. On the contrary, model ...

Traditional cheeses harbour complex microbial consortia that play an important role in shaping typical sensorial properties. However, the microbial metabolism is considered difficult to control. Microbial community succession and the related gene expression were analysed during ripening of a traditional Italian cheese, identifying parameters that could be modified to accelerate ripening. Afterw...

The present work was aimed to define and validate farmstead production of lactose-free Pecorino di Osilo cheese, fresh ricotta cheese, and salted and smoked ricotta cheese (Ricotta mustia). The enzymatic activity of the commercial preparation containing lactase (1.1 g/mL), preliminarily tested using a spectrophotometric titration, showed activity equal to 4950±40 neutral lactase unit/g. The amo...
