Noni juice and preparation method thereof

Abstract

The invention discloses morinda citrifolia juice and a preparation method thereof. The invention provides morinda citrifolia juice. The morinda citrifolia juice is prepared from the following raw materials in parts by weight: 40-60 parts of morinda citrifolia, 0.03-7.5 parts of a color fixative and 40-60 parts of water, the color fixative comprises one or more of vitamin C, anhydrous citric acid and calcium chloride. According to the invention, the color fixative of a specific variety and a specific content is combined, so that self-enzymatic oxidation of the morinda citrifolia juice can be effectively delayed, the color of the juice is protected, the storage life of the juice is prolonged, the quality and attractiveness of the juice are improved, and later processing of morinda citrifolia juice products is facilitated; important nutritional ingredients such as amino acids, polyphenols, vitamins and minerals in the morinda citrifolia fruits are reserved to the maximum extent, and the multiple health-care effects of oxidation resistance, tumor resistance, free radical removal, gastrointestinal digestion promotion, immunity enhancement and the like of the freshly squeezed morinda citrifolia fruit juice are improved.

AI Technical Summary

Problems solved by technology

Though Noni fruit is dried and must go through the technical process of Noni freshly squeezed fruit juice before making fruit powder, as patent CN106036341A discloses the method for making Noni fruit powder before fresh juice, but lacks the color protection of Noni fruit juice in its technological process steps; however, the enzyme system in Noni fruit is very developed, and the feed liquid is easily oxidized during the pressing process, and the feed liquid usually browns rapidly within a few seconds to a few minutes. It turns into an unacceptable dark brown within 10 minutes to a few hours, which greatly affects the subsequent processing and promotion of the product

However, the operation of increasing the temperature and time of deactivating enzymes to improve the effect of deactivating enzymes will destroy the nutritional components such as vitamins and amino acids in Noni fruit.
