Infant foods have a special place among food products mainly because of nutritional aspects and preparations methods. A great increase of baby foods incomes is predicted in near future. Formulation, handling, and storage of baby foods are important to keep nutritional quality and physicochemical properties of these foods. During storage some reactions and interactions occur which change physicochemical and nutritional properties of baby foods. Lactose crystallization, Maillard reaction, oxidation, and interactions between micronutrients and other components are the most important aspect of preparation and storage of baby foods. These reactions and interactions influence physical properties such as flowability of powder, solubility, and other functional properties. Controlling of storage conditions such as temperature and moisture content and oxygen quantity in headspace of product is required to keep product quality. In this paper the composition and interactions of baby foods between major components and their effect on nutritional quality of baby foods are explained.

Cellulose is the most abundant and a low-cost biodegradable by-product in the food and agricultural industries. Electrospun cellulosic nanofibers have remarkable physicochemical properties that make them attractive for many applications in the food sector. In this review, electrospinning is investigated as an easy method for producing nanofibers from polymers. Moreover, the most important applications of cellulosic nanofibers in food science are presented. These applications are (a) immobilization of bioactive substances such as enzymes, vitamins, and antimicrobials; (b) nutraceutical delivery systems and controlled release of materials; (c) as biosensors; (d) filtration; and (e) for reinforcing composites and in films. Finally, some potential risks of using electrospinning in food science are reviewed.
