Embodiment Construction

[0020] The present invention will be further described below through specific examples.

[0021] 1. Hydrochloric Acid Degradation of Alkali Extracted Polysaccharide from Passion Fruit Peel

[0022] (1) Effect of hydrochloric acid concentration on polysaccharide degradation:

[0023] Alkali-extracted polysaccharides were prepared into a 5 mg / mL solution, and the reaction time was 60 minutes, and the reaction temperature was 60 °C. The effect of degradation. After the reaction was finished, it was adjusted to neutrality, dialyzed in running water for 48 hours, and freeze-dried after concentration ( figure 1 ).

[0024] (2) Effect of reaction temperature on polysaccharide degradation:

[0025] Alkali-extracted polysaccharides were formulated into a 5 mg / mL solution, and the reaction time was 60 minutes, and the concentration of hydrochloric acid was 0.3mol / L. The effect of degradation. After the reaction was finished, it was adjusted to neutrality, dialyzed in running water...

Abstract

The invention discloses a preparation method and a degradation process of passiflora edulis peel enzyme-assisted alkali-extracted polysaccharide, and particularly relates to application of degraded passiflora edulis peel alkali-extracted polysaccharide in preparation of an antioxidant. The research investigates the influence of three acid degradation conditions of hydrochloric acid concentration,temperature and time and three enzyme degradation conditions of enzymolysis time, pH value and temperature on the in-vitro antioxidant activity of the degraded passiflora edulis peel alkali-extractedpolysaccharide, and lays a foundation for deep research and development of the passiflora edulis peel alkali-extracted polysaccharide.

Description

technical field [0001] The invention belongs to the field of medicinal food research and development, and in particular relates to a preparation method of passion fruit peel enzyme-assisted alkali extraction polysaccharide and a degradation process thereof. Background technique [0002] Passion fruit, also known as egg fruit, is a tropical fruit. The pulp not only contains rich vitamins, amino acids, organic acids and other ingredients, but also has important biological functions. The peel accounts for about 50% of the whole fruit, and contains active ingredients such as flavonoids, natural pigments, dietary fiber, and pectin. These ingredients endow passion fruit peel extracts with physiological activities such as anti-inflammatory, anti-oxidation, anti-cancer, and anti-anxiety . [0003] The traditional hot water extraction method is simple, and the extraction rate and production efficiency of polysaccharides are relatively low. In order to improve the extraction rate of ...
