In recent years, using of biodegradable materials instead of synthetic oil materials has been growingly increased with no non biodegradation and non recycling properties of oil compounds. These biopolymer materials produce through interactions in animals, plants and microorganism. In this study we have reviewed the advantages and disadvantages of biopolymers and their production in details.

Today, probiotic foods as processed foods include sufficiently probiotic bacteria used to promote and provoke lactose digestion, calcium absorption, vitamin synthesis and immune system of body, reducing blood cholesterol, preventing different cancers specially colon cancer. The target of this study was to investigate the encapsulation of probiotic bacteria with dominant variety called L. Casei and their viability in wafer cream. The culture activated at 37°C, then bacteria precipitation prepared by centrifuge, finally encapsulated by sodium alginate and sodium chloride in order to improve their resistance to acidic conditions. Encapsulated bacteria in sufficient amount added to the wafer formulation (10 7cell/ml). Provided cream kept 6 weeks. After finishing storing time, seeds dissolved in MRS citrate agar to separate completely then cultured in media to calculate their population. Results revealed that encapsulated bacteria showed more sustainability than free bacteria.

Статья научная

This article is a brief introduction of theoretical results of cloud point extraction in food science. In this article, we present a collection of introductions on cloud point extraction, besides the advantages and its functionality have been studied and described the way this method demanded. This easy and simple method is affordable and has a wide range of application in determination of different samples and the ability of evaluating analyte in ng levels is possible in this method.
