Embodiment 1-15

[0018] Embodiments 1-15 respectively provide a method for preparing concentrated loquat fruit juice, and the components and dosages used in each embodiment are shown in Table 1 below.

[0019] The specific production steps are as follows:

[0020] (1) Cleaning: After the mature loquat is cleaned with a brushing machine, the lint and dirt on the surface of the loquat are removed, then it is lifted and sprayed for cleaning, and then the core is removed by a corer to obtain the cored loquat.

[0021] (2) Blanching: Put the pitted loquat into boiling water and boil for 2-3 minutes to obtain the pretreated loquat.

[0022] (3) Mix the compound glue, sugar and water, stir and heat to 100°C to obtain a glue solution.

[0023] (4) When the glue is cooled to below 90°C, soak part of the pretreated loquats in the glue, and before the glue is cooled to 70°C, the pretreated loquats are taken out from the glue, and the pretreated loquats are left standing. When the pretreated loquat is c...

Abstract

The invention relates to the technical field of food, in particular to a preparation method of concentrated loquat juice. Loquat granules are coated with glue solution prepared from compounded glue toform loquat pulp granules, as the glue solution has high transparency, the appearance is not affected after the loquat granules are coated with the glue solution, the outer glue solution forms gel after cooling, and the gel protects the loquat granules from being directly contacted with loquat juice for a long term, so that rotting of the loquat granules is prevented. Besides, the gel outside thegranules has certain elasticity, so that instant granules have certain elastic and tough taste. Pitted loquats are pretreated to form pretreated loquats, loquat juice produced from the pretreated loquats can effectively reduce browning, and the juice color is well kept. Concentrated loquat juice containing loquat pulp can be prepared by the method, the loquat juice is tasty, the juice color is well kept, and loquat pulp granules taste good.

Description

technical field [0001] The invention relates to the field of food technology, in particular to a preparation method of concentrated loquat fruit juice. Background technique [0002] Juice drinks are popular among consumers, not only delicious but also nutritious. But the existing fruit juice drinks, because the pulp will become soft and rotten after soaking in the juice for a long time, not only the taste is bad, but also seriously affect the appearance of the juice, the rotten pulp will make the juice turbid, except for fruit oranges, very Few berries. Therefore the kind of existing fruit juice drink is subject to certain restriction. In addition, loquat is a characteristic fruit in southern my country, rich in cellulose, pectin, carotene, malic acid, citric acid, potassium, phosphorus, iron, calcium and vitamins A, B, and C. Loquat has the effects of clearing away heat, moisturizing the throat, quenching thirst, and harmonizing the stomach, and has a good therapeutic an...
