Problems solved by technology

[0005] At present, the method for the preservation of multiple loquat pulp has occurred, but these methods have all shown the following deficiencies: 1. The process of processing is complicated, resulting in high cost and low efficiency
2. Added food additives often contain toxic and harmful ingredients that are harmful to the human body and often exceed the standard, destroying the nutrients in the pulp
3. Cannot effectively inhibit the discoloration and deterioration of fruit pulp
[0006] Aiming at the above problems, the Chinese patent (application number: CN201010170340.0) has proposed a good solution, which is composed of sodium tripolyphosphate, sodium iso-Vc, sodium metabisulfite, β-cyclodextrin, and sodium edetate Color protectant, but the amount of additives is still slightly higher, reaching 0.3-0.8g / kg pulp

Abstract

The invention relates to a loquat color fixative as well as a preparation method and a room-temperature preservation method of loquat pulp, and belongs to the field of food processing. The loquat color fixative consists of the following ingredients in percentage by weight: 35-45% of sodium tripolyphosphate, 5-20% of d-sodium erythorbate, 3-9% of beta-cyclodextrin, 0.01-1% of edetate disodium and 20-58% of sodium chloride. The invention further provides a preparation method of loquat pulp, wherein the loquat color fixative is used. The loquat pulp prepared by the preparation method disclosed bythe invention can be stored at room temperature. Through the addition of the loquat color fixative disclosed by the invention, the effect of protecting the color of loquats can be achieved; and besides, the color fixative is low in dosage and harmless in ingredients, and is an ideal choice of color fixatives.

Description

technical field [0001] The invention relates to a loquat color-protecting agent and a method for preparing and storing loquat pulp at normal temperature, belonging to the field of food processing. Background technique [0002] The nutrients contained in the edible part of loquat fruit include protein, fat, carbohydrates, calcium, iron, gamma vitamins, carotenoids, etc. Among them, calcium, phosphorus and carotene are significantly higher than other common fruits, and contain essential nutrients for the human body. of 8 amino acids. It is a kind of fruit that is very popular and often eaten by the public. The drink with loquat pulp as the main ingredient is orange in color. In addition to the function of a general drink, it also has the functions of moistening the lungs and clearing away heat. [0003] If an enterprise wants to produce loquat drinks on a large scale, it will have a large amount of loquat raw material storage, but fresh loquat fruit is inconvenient to preserv...
