Embodiment 1

[0031] 30% protein mass content, 30% DPPH free radical scavenging rate, Fe 2+ The chelating power is 27%, the ABTS free radical scavenging rate is 33%, and the Korean pine seed meal protein peptide (prepared according to the method described in ZL201310513028.0) with a molecular weight of 1000-3000 Da is weighed for 10 g for use.

[0032] Weigh the blueberry fruit, wash with deionized water, and grind the blueberry fruit for 20 minutes. The fineness of the obtained blueberry pulp is 80 mesh. For the pulp part, keep the blueberry pulp; and then process it through a high-voltage pulsed electric field. At room temperature, the blueberry pulp obtained after the pretreatment is prepared with deionized water into a treatment solution with a mass concentration of 8 mg / mL, and the pipeline is first cleaned with distilled water. Sterilize with ethanol solution with a mass concentration of 70%, then clean the pipeline again with distilled water, and extract the treatment liquid with a m...

Abstract

A pine-nut peptide / blueberry anthocyanidin antioxidation oral liquid which is prepared from raw materials of protein peptide of red pine nut and blueberry anthocyanidin and enhances anti-oxidation ability and a preparation method thereof belong to the technical field of deep processing of agricultural products and comprehensive utilization of byproducts. The preparation method comprises the following steps: using protein peptide of red pine nut with protein content being 30-40% and with molecular weight being 1000-3000 Da as a first raw material, using blueberry anthocyanidin which is obtained after pretreatment, high intensity pulsed electric field treatment, organic solvent extraction and has anthocyanidin extraction rate being 9% and above as a second raw material, using refined honey as an auxiliary material, and uniformly mixing and blending; carrying out thermal insulation on the mixed liquor at 45-50 DEG C for 20-30 min, sterilizing, and standing for 20-30 min so as to prepare the pine-nut protein peptide / blueberry anthocyanidin antioxidation oral liquid with antioxidant activity being 40-60%. According to the invention, the antioxidation-enhancing ability is taken as the target activity, and the bottleneck of single functional performance of products in the technical fields of deep processing of agricultural products and comprehensive utilization of byproducts is broken through.

Description
