Our objective was to develop a rapid method for measuring fat, protein, solids, and salt content of Cheddar cheese using a mid-infrared (MIR) transmittance analysis. Currently, quality assurance is done using near-infrared (NIR). For MIR analysis, Cheddar cheese (about 9 g) was blended with a sodium metasilicate solution (about 85 g). Cheese was blended to a uniform particle size (about 3 to 4 ...

Lactobacillus helveticus, a ubiquitous bacterial species in natural whey cultures (NWCs) used for Swiss Gruyère cheese production, is considered to have crucial functions for cheese ripening such as enhancing proteolysis. We tracked the diversity and abundance of L. helveticus strains during 6 months of ripening in eight Swiss Gruyère-type cheeses using a culture-independent typing method. The ...

Background: Despite its high content of saturated fatty acids, cheese does not seem to increase plasma total and LDL-cholesterol concentrations when compared with an equivalent intake of fat from butter. This effect may be due to the high calcium content of cheese, which results in a higher excretion of fecal fat. Objectives: The objective was to compare the effects of diets of equal fat conten...

The aim was to improve nutritional quality of cows’ milk and use it as raw material for mozzarella cheese. Three treatments were tested with 23 healthy animals ranging power: control, palm oil and coconut oil. Collection was performed in 21 days and another after 36 days. Proximate composition (moisture, ash, fat, protein, carbohydrates), sensory, color (CIE L, a, b) and texture were made for m...

To understand the possible proteolytic contribution of yeast during cheese ripening, Debaryomyces hansenii 212 was isolated from commercial blue-veined cheese and incubated in a medium containing casein. Growth and casein degradation were recognized at the cheese-ripening temperature. Proteolytic activity was found in the intracellular fraction, and the enzyme, which was attached to the cell wa...

The behaviour of Escherichia coli O157:H7 was studied during the manufacture and storage of Iranian white cheese in brine. Cheese was manufactured using pasteurized cow milk and inoculated with E. coli O157:H7 with inoculum level of 103 cfu/ml. Four treatments were designed. Cheeses were made with or without starter culture and kept immersed in 6 or 8% salt brine during ripening and storage. Ch...

The aim of the study was to develop a symbiotic cottage cheese containing Lactobacillus delbrueckii UFV H2b20 and inulin, and to evaluate the survival of this bacterium when the cheese was exposed to conditions simulating those found in the gastro-intestinal tract. Throughout the entire whole shelf-life period of the cheese, the probiotic cell counts were higher than those recommended for probi...

The American Cheese Society (ACS) is the leading organization supporting and promoting cheese in North America. In this role, ACS represents a broad range of producers, distributors, retailers, and discerning consumers who appreciate the diversity and quality of American-made artisan, farmstead, and specialty cheeses. ACS is thankful for the opportunity to comment on the draft report issued by ...

Flavor production among 12 strains of Debaryomyces hansenii when grown on a simple cheese model mimicking a cheese surface was investigated by dynamic headspace sampling followed by gas chromatography-mass spectrometry. The present study confirmed that D. hansenii possess the ability to produce important cheese flavor compounds, primarily branched-chain aldehydes and alcohols, and thus importan...
