The article presents experimental study on the feasibility of using edible films (in the coating) as a means of preventing staling and method of increasing the biological value of gingerbread products. Grounded components of edible coating. Based on the organoleptic and physico-chemical showers properties (moisture content, water absorptivity and friability) proved the feasibility and necessity of use last one edible coating, which also can increase the biological value of products, as part of the cover is linseed oil.
Abstract:The results of study of foods and biodegradable film structure with the use of infrared spectroscopy (IR spectra) are presented. For the first time detailed decodings of IR spectra of some foods and biodegradable film packaging materials are shown. Interpretation of the spectra of basic biopolymers of foods and biodegradable films is given. It is corroborated with the help of IR spectra that the chemical reactions in biopolymers when heated to 130 °C do not occur, which makes it possible to use biologically valuable raw materials. Furthermore, the expediency of use of IR spectroscopy for studying changes in foods and films produced on biopolymer base is established. IR spectroscopy is a fast method that allows you to monitor changes that occur with the raw materials in the technological process. Previously, IR spectroscopy was used to identify the compounds in chemical synthesis. This study shows that IR spectra can be used for study of foods and biodegradable film structure.
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.
