Advantages And Disadvantages Of Chitosan
CONCEPT OF SHELF-LIFE EXTENSION: Chitosan is a polymer which is extracted from chitin. It is natural, and thusly biodegradable and biocompatible. As a novel food preservative, chitosan offers the possibility to form edible film coatings on fresh or processed perishable foods in order to extend their shelf life. The chitosan film has antimicrobiological properties which allow it to protect the food it is coating. In most foods, microbial contaminations occur predominantly at the surface, meaning using edible films such as chitosan allows minimal space between the foods’ surface and its’ environment. However, the coating has weak mechanical properties, and is permeable for gas and water vapour. Blending chitosan with starch improves its mechanical properties and allows a better novel food preservative. ADVANTAGES: - As chitosan is the second most abundant carbohydrate after cellulose, it’s not unusual that its waste exceeds 25bn tonnes per year. Using chitosan as a food preservative allows for reuse of this waste, making its use environmentally beneficial; while also reasonably cheap and cost-effective in production and usage. - Its biodegradability also allows chitosan biofilms to be beneficial to the environment. - The chitosan film has antibacterial and antifungal properties, meaning that it ultimately prolongs shelf-lives of the foods which it coats. - As chitosan film is a polysaccharide which physically coats the food product, it offers the advantage of being edible,

Advantages Of Radioisotopes
806 Words | 4 PagesRadioisotopes for Killing Germs and Bacteria Radioisotopes are isotopes that as they have an unstable nucleus because they are very big or because the number of protons and neutrons isn’t balanced therefore, they emit particles to become balanced, thus, they become radioactive isotopes, also known as radioisotopes. This can be beneficial, but it can also be extremely dangerous. Radioisotopes are used for numerous things; several examples: to spoilage and eliminating food-borne pathogens, such as salmonella, and treat cancer. Using Radioisotopes for killing germs and bacteria is common, but it had it bad parts too. It is also known for food irradiation.

Fish Oil Lab Report
867 Words | 4 PagesIt is used to encapsulate fish oil to offer effective protection against physical and chemical degradations, prevent or slow volatilization, mask unpleasant odors, extend shelf-life and provide sustained and prolonged release characteristics [4]. Microencapsulation of fish oil inhibits photooxidation and free radical autoxidation of EPA and DHA by protecting it from light and oxygen, leading to sensory stabilization of the oil. Fish oil microencapsulation was achieved using polymers such as chitosan, gelatin, maltodextrin, starch, whey proteins and plant gums via spray drying, coacervation, ultrasonication and membrane emulsification techniques. Various techniques for microencapsulation of fish oil are listed in Figure
