  • Preparation method of citric acid modified starch with digestion-resistant property
    Patent number: 11453730
    Abstract: The method employs citric acid as the modifier, combines the citric acid with starch, achieves the good modification effect of starch at high temperature, and improves the digestion-resistant property of starch. Citric acid itself is nontoxic, the process conditions are mild and the treatment methods are relatively safe, which shows very high practical values. In the method, starch and citric acid are cross-linked by using the infrared treatment technology, and the dry heating treatment is used to promote the modifier citric acid into starch, thereby achieving significant and stable modification effects, and high modification efficiency.
