Abstract
Modification of potato starch with adipic acid and research of modification product as raw materials for food biodegradable packaging
Highlights
The aim of our work was to study the modification of potato starch with adipic acid chloride in order to further physicochemical study of the obtained product and use, for example, as an effective film former of biodegradable films/coatings
The changes that occurred as a result of the acylation reaction of potato starch with adipic acid chloride are confirmed by a number of factors
In the spectrum of native starch (Figure 1) and there is a fairly wide intense band, which is at 3389.35 cm-1, and in the spectrum of the modified sample the band lies in the region of stronger fluctuations at 3411.08 cm-1, which is due with the degree of participation of the OH group in the formation of hydrogen bonds
Summary
The aim of our work was to study the modification of potato starch with adipic acid chloride in order to further physicochemical study of the obtained product and use, for example, as an effective film former of biodegradable films/coatings. Starch, modified chloride, phosphate, sulfuric acid, acetic anhydride, acetic and succinic acid, potassium hydroxide, ammonium persulfate propionic acid chloride (Hui Chi et al 2008) acetyl chloride malic acid (Shulga O.S. et al, 2018) etc. A significant amount of work concerns the interaction of starch different types (Bhosale R. et al, 2006) with fatty acid chlorides (Fathi F. et al, 2014; Junistia L. et al 2008). Materials based on native and modified starch are biodegradable and are used as environmentally friendly packaging materials It is important to expand the range of raw materials for environmentally friendly packaging materials
