OBJECTIVE To compare variety and diversity patterns and dietary characteristics in Guatemalan women. MATERIAL AND METHODS Two non-consecutive 24-h recalls were conducted in convenience samples of 20 rural Mayan women and 20 urban students. Diversity scores were computed using three food-group systems.Variety and diversity scores and dietary origin and characteristics were compared between set...

Food preservation is an action or a method of maintaining foods at a desired level of properties or nature for their maximum benefits. In general, each step of handling, processing, storage, and distribution affects the characteristics of food, which may be desirable or undesirable. Thus, understanding the effects of each preservation method and handling procedure on foods is critical in food p...

With the increase in consumer awareness, demand for minimally processed foods and ecofriendliness, various technologies were developed for food processing and preservation. The conventional thermal food preservation and processing techniques appears to have the shortcoming of adversely affecting the food quality, organoleptic properties and nutrients. However, many non-thermal food preservation...

Lactic acid bacteria and their antimicrobial metabolites have potential as natural preservatives to control the growth of spoilage and pathogenic bacteria in foods. To date, nisin is the only bacteriocin that has found practical applications in some industrially processed foods. Its antibacterial activity and possible use as a biopreservative has been studied in a large number of food systems. ...

Thermal and non-thermal technologies are both used in the processing and preservation of foods. Recently, awareness about good nutrition coupled with the increasing demand for fresher tasting food have paved theway for new food processing technologies.These include thermalprocessingmethods such asmicrowave (MW), radiofrequency (RF), infrared (IR) heating, pressure-assisted thermal sterilization...

This study investigated the possibility that sublethal food preservation stresses (high or low temperature and osmotic and pH stress) can lead to changes in the nature and scale of antibiotic resistance (ABR) expressed by three food-related pathogens (Escherichia coli, Salmonella enterica serovar Typhimurium, and Staphylococcus aureus). The study found that some sublethal stresses significantly...

Antimicrobial packaging is one of the most promising active packaging systems. Antimicrobial packaging is the packaging system that is able to kill or inhibit spoilage and pathogenic microorganisms that are contaminating foods. A tremendous effort has been made over the last decade to develop and test films with antimicrobial properties to improve food safety and shelf life. For food preservati...

Electrochemical reactions, especially those involving the electrode material, are considered one of the challenges facing the commercialization of the process of food preservation using pulsed electric fields. These undesired reactions lead to the migration of electrode material components into the food under treatment affecting food quality and taste, electric field distribution, and electrode...
