bacterium widely distributed in the soil and water. It is considered as an important enterotoxigenic food borne pathogen causing diarrhoeal and emetic food poisoning (Johnson, 1984; Kramer and Gilbert, 1989). Apart from gastroenteritis, B. cereus has a role in causing variety of non-gastro intestinal tract infections such as meningitis, endopthalmitis, endocarditis, periodontitis, osteomyelitis...

The term food preservation refers to any one of a number of techniques used to prevent food from spoiling. The following are the general methods of food preservation:  application of heat, such as canning and preserving, pasteurization, evaporation, sun-drying, dehydration and smoking,  application of cold, as ill cold storage, refrigeration and freezing,  the use of chemical substances such...

Most food products are highly perishable as they constitute a rich nutrient source for microbial development. Seafood is one of the most highly perishable food products due to the chemical effects of atmospheric oxygen and the growth of spoilage microorganisms. Therefore, the spoilage of food depends up on the physiological state of spoilers and on their ability to resist the processing/storage...

Food spoilage can be defined as “any sensory change (tactile, visual, olfactory or flavour)” which the consumer considers to be unacceptable. Spoilage may occur at any stage along food chain. Spoilage may arise from insect damage, physical damage, indigenous enzyme activity in the animal or plant tissue or by microbial infections. Most natural foods have a limited life. Perishable foods such as...

Leuconostoc gasicomitatum is a psychrotrophic lactic acid bacterium causing spoilage of cold-stored, modified-atmosphere-packaged (MAP), nutrient-rich foods. Its role has been verified by challenge tests in gas and slime formation, development of pungent acidic and buttery off odors, and greening of beef. MAP meats have especially been prone to L. gasicomitatum spoilage. In addition, spoilage o...

Food preservation through natural methods represents one of the concerns world‐ wide to solve economic losses due to microbial decomposition of raw materials and foodstuffs. However, public concern over the emergence of strains resistant to many antibiotics, particularly pathogens such as E. coli and Salmonella sp. draw much attention as new challenge in food industry is to find new alternative...

In the food industry, contamination by spoilage microorganisms results in severe safety and economic problems. In the sake-brewing process, spoilaging phenomena caused by several Lactobacillus species, so-called hiochi bacteria, seriously deteriorate the quality of sake, such as lowering the pH, increasing turbidity, and producing offflavors [1,2]. Sake with an ethanol concentration greater tha...

ARTICLES SUMMARY Predictive microbiology and quantitative microbial risk assessment are rapidly developing disciplines that use mathematical models to quantitatively estimate the presence and growth of microbes in food products. This report explains how these techniques were used in troubleshooting a milk spoilage problem. The central objective of this article is to demonstrate the concept and ...

Food spoilage may be defined as a process that renders a product undesirable or unacceptable for consumption and is the outcome of the biochemical activity of a microbial community that eventually dominates according to the prevailing ecological determinants. Although limited information are reported, this activity has been attributed to quorum sensing (QS). Consequently, the potential role of ...
