Dairy products are an important food group highly suggested by nutritionists. This food category is one of the most perishable, so extending their shelf life and keeping them fresh for a longer period of time is a matter of importance. Since consumers are now more aware of the possible hazards of preservatives, technologists and researchers have attempted to introduce novel preservative-free methods instead. One of these techniques is modified atmosphere packaging (MAP), which alters the natural gas surrounding the product in the package in order to delay deteriorative changes. In this paper, a review is made on the field of cheese MAP. Reported results revealed the potentiality of MAP in increasing cheese sensorial and microbial shelf life by carefully designing for an individual cheese.
The application of liposomes as potential carriers to deliver food components is considerably an innovative technology. While the application of liposome technology has been very limited to date, researches indicating the potential of liposomes for improving the flavor of ripened cheese using accelerated methods, the targeted delivery of functional food ingredients, the synergistic delivery of ascorbic acid and tocopherols for promoting antioxidant activity in foods, and the stabilization of minerals (such as iron) in milk have been performed. In the food industry, liposomes and nanoliposomes have been employed to encapsulate flavoring and nutritive agents, and also, they have been suitable candidates to deliver antimicrobials. In this paper, application of lipase, proteinase, nisin, and flavor-containing liposomes in products during the processing (such as cheese maturity) as well as the application of liposomes-encapsulated micronutrients (such as iron) in milk are reviewed.
The objective of present study was to investigate the impact of Brown Rice flour (BR) incorporation, at three different levels of 5, 10 and 15 % to the Wheat Flour (WF) preparations on rheological properties of wheat-based dough and quality of wheat-based flat bread. The BR flour incorporation mainly affected the chemical properties of flours, the rheological characteristics of dough and, quality and shelf life of bread. The protein-related properties of flours principally experienced reduction; however, the ash content had an increase, along with BR flour incorporation. The rheological properties of dough were affected considerably by BR flour substitution, wherein the sample containing 5 % BR flour was closest to BR flour-free dough (control). Regarding the yielded bread, BR flour addition affirmatively affected sensorial properties and firmness quality evaluation, wherein the bread made from dough with composite flour fortified with 5 % BR flour was scored the best. The findings from instrumental firmness quality assessment were confirmed as the bread containing 5 % BR flour remained softer and demanded lowest force to be compressed over the storage period. Overall, results showed that adding BR flour up to 5 % can be used in baking of flat bread since it meets the required criteria.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
