This study was conducted to determine the survival of Escherichia coli O157:H7 during the ripening period of herby cheese made traditionally from raw cow milk. The cheese milk was inoculated with E. coli O157:H7 at the level of 3 log and 5 log cfu/mL, and then both manufactured herby cheeses were divided into two groups equally. The herby cheeses were stored by using two different methods for r...

OBJECTIVE To investigate the salt (sodium chloride) content in cheese sold in UK supermarkets. STUDY DESIGN We carried out a cross-sectional survey in 2012, including 612 cheeses available in UK supermarkets. METHODS The salt content (g/100 g) was collected from product packaging and nutrient information panels of cheeses available in the top seven retailers. RESULTS Salt content in chees...

Late blowing in Swiss cheese, a result of unwanted gas production during ripening, isunacceptable to consumers, and causes economic loss to manufacturers. Cheese processorshave raised concerns that feeding dried distillers’ grains with soluble (DDGS) to cows leadsto this defect, in part, because of Clostridial spores. In this study, the effect of feeding DDGSto lactating dairy c...

Listeria monocytogenes is a foodborne pathogen that can cause serious invasive disease in humans. Because human listeriosis cases have previously been linked to consumption of contaminated cheese, control of this pathogen throughout the cheese production chain is of particular concern. To understand the potential for L. monocytogenes transmission via São Jorge cheese, a Portuguese artisanal che...

BACKGROUND Healthy foods have been met with marked success in the last two decades. Lupine flours, protein concentrates, and isolates can be applied as a substance for enriching different kinds of food systems such as bakery products, lupine pasta, ice cream, milk substitutes. Imitation processed cheese is made from mixtures of dairy and/or non dairy proteins and fat/oils and is variously label...

Short-chain free fatty acids (FFA) are important sources of cheese flavor and have been reported to be indicators for assessing quality. The objective of this research was to develop a simple and rapid screening tool for monitoring the short-chain FFA contents in Swiss cheese by using Fourier transform infrared spectroscopy (FTIR). Forty-four Swiss cheese samples were evaluated by using a MIRac...

In the past fifty years, no recorded case of botulism has been attributed to surface ripened cheese (NIeyer and Eddie, 1950). When cheese spread was prepared from one type of surface ripened cheese, botulinum toxin was demonstrated in only one out of several million jars (Dauer, 1952). The fact that botulism was never observed with the original surface ripened cheese from which cheese spreads w...

In this study the methods of Hungate were used to quantitate the anaerobic bacteria present in commercially available ground beef, cheddar cheese, and German hand cheese. Of 235 anaerobic roll-tube isolates from ground beef and German hand cheese, all were facultative anaerobes. Of 213 anaerobic roll-tube isolates from cheddar cheese, 91% were facultative anaerobes and 9% were obligate anaerobe...

Increasing incidence of food-borne disease along with its social and economic consequences have led to conducting extensive research in order to produce safer food and develop new antimicrobial agents; among them, extensive use of probiotics and bacteriocins as biological additives is of significant importance. The aim of the present study was to evaluate the interactions (growth behavior and s...

Vitamin B12 is a water-soluble molecule composed of a tetrapyrrolic complex with a cobalt atom at its centre. It is an essential regulatory element, synthesized only by bacteria; for this reason it is present only in food of animal origin and the daily requirement for humans is about 1 to 2 mg. Since milk and dairy products provide a significant dietary cobalamin intake, an ultra performance li...
