Objective To develop artificial hypoglycemic rice with leafy grass as a nutritional supplement, optimize its formula, and analyze its inhibitory activity on α-glucosidase and sensory quality. Methods The orthogonal experimental design was used to optimize the formula parameters of artificial rice, with corn amylose and rice starch as the main raw materials and edible leaf grass powder as the functional additive. The inhibitory activity of α-glucosidase was detected by enzyme labeling instrument to evaluate the hypoglycemic effect the samples, and the food sensory analysis was carried out according to the sensory evaluation method. Results The water extract of edible leaf grass showed a high inhibitory rate on α-glucosidase with an inhibitory concentration (IC50) value 1.189 mg/mL, which was close to the inhibitory effect of the positive control acarbose. The optimized formula for producing artificial rice from edible leaf grass performed excellently in sensory evaluation, with good flavor, texture and appearance. Conclusion Edible leaf grass has excellent nutritional value and potential hypoglycemic activity. The artificial hypoglycemic rice develops based on it not only meets the special needs of diabetes patients, but also provides a new choice for the health food market, and has broad application prospects.
