Iranian PhD Student Finds Way to Increase Shelf Life of Oilcake by Enzyme Microcapsules
Golnaz Soltani from the agricultre faculty of the university defended her doctoral thesis in the field of food industry, entitled ‘production of microcapsules containing heat-resistant α-amylase enzyme and sour tea anthocyanin nanoemulsion and its application in oilcake containing wheat bran and investigation of antioxidant activity performance during shelf life and release in the digestive tract’.
The thesis was compiled with the aim of in-depth analysis of oxidation processes and investigation of the effect of using heat-resistant encapsulated alpha-amylase enzyme, natural antioxidants and encapsulation on the quality, stability and safety of oilcake consumption.
In this study, physicochemical parameters, storage conditions, the role of heat-resistant alpha-amylase enzyme, and the effect of anthocyanin extract in sour tea and the role of microencapsulation in increasing the shelf life of oilcake have been carefully examined.
The results of the study provide scientific and practical solutions to improve the processing quality and increase the shelf life of oilcakes, which can be used in the food industry.
In a relevant development in 2024, Iranian researchers had managed to increase the shelf life of food by producing a new antimicrobial pad which can be placed as a single or double layer on product packaging.
The new antimicrobial pad, which is the result of years of research and development, is produced based on natural materials and is easily removed from the packaging, and it can significantly increase the shelf life of food products, specially fresh meat.
Increasing the shelf life of food by inhibiting the growth of microbes and preventing premature spoilage of products, greater food safety by reducing the risk of microbial contamination and disease transmission, decreasing food waste by increasing the useful life of products, being compatible with the environment and easy separation from the packaging to prevent harm to the environment are among the advantages of this product.
