Method for extracting vitamin C from shine skin papayas

Abstract

The invention discloses a method for extracting a vitamin C from shine skin papayas. The method comprises the following steps: (1) picking fresh shine skin papayas, cleaning the picked shine skin papayas, separately cutting the cleaned shine skin papayas in an extraction protective solvent, and deseeding the cut shine skin papayas; (2) adding the flesh of the cut shine skin papayas and the extraction protective solvent in a vacuum pulping machine together, and pulping the flesh of the cut shine skin papayas and the extraction protective solvent to obtain a sizing agent ; (3) adding the generated sizing agent after pulping to a vacuum mixer to perform vacuum mixing; (4) filtering the materials obtained in the step (3) to obtain a filtrate, standing the filtrate for layering, and performing separation to obtain an organic phase; (5) adding water of which the pH is smaller than 7 to the organic phase obtained in the step (4), and performing vacuum mixing for more than 2 hours; (6) standing a mixture for layering, and performing separation to obtain an aqueous phase; (7) performing vacuum concentration on the aqueous phase to enable the aqueous phase to be dried, and performing freeze drying so as to obtain the vitamin C crude product. The extraction method disclosed by the invention can extract the vitamin C in the shine skin papayas, the extraction method is simple, and the method is suitable for large-scale popularization and application. Extracts are high in the content of the vitamin C.

Description

technical field [0001] The invention relates to the technical field of papaya deep processing, in particular to a method for extracting vitamin C from papaya with light skin. Background technique [0002] Papaya (Chaenomeles sinensis) is a plant of the genus Papaya in the family Rosaceae. Because the skin of the fruit is still smooth and does not shrink after drying, it has another name called papaya with light skin. Its fruit is rich in nutrition, rich in organic acids, amino acids, polysaccharides, flavonoids, triterpenes and their glycosides and other compounds. One of the most valuable new economic tree species, the market prospect is broad. At present, papaya has become a characteristic medicinal material and processed edible fruit in many places such as Heze in Shandong, Yunxian in Hubei, Baihe in Shaanxi, and Tongbai in Henan. [0003] For a long time, papaya with light skin has been cultivated with seedlings to build orchards, and the output is uneven. At the same...

But there is no extraction method for vitamin C in papaya papaya in the prior art

In addition, the hardness of papaya with papaya is relatively high, and it is difficult to fully crush it, which will also cause the flavonoids in papaya with papaya to be extracted more thoroughly.
