Article Description

Producing high-quality gluten-free whole-millet cakes is challenging for the food industry. This study investigated the effects of chitosan oligosaccharides (COS) on the structure and shelf-life of whole-millet cakes. The Fourier transform infrared spectroscopy and X-ray diffraction results indicated that hydrogen bonds formed between COS and millet starch reduced the relative crystallinity of whole-millet cakes. With increasing COS, the migration of free water in the system decreased, improving the water retention capacity. An appropriate concentration of COS improved the continuous structure of the gluten network and thus maintained the integrity of the internal structure of whole-millet cakes. At 0.8% COS, changes in the color, hardness, and springiness of whole-millet cakes, as well as moisture loss from them were minimal during storage. Additionally, COS addition extended their shelf-life by 3–6 days. In conclusion, COS can improve quality and storage stability of gluten-free foods.
