Problems solved by technology

[0005] At present, there have been multiple methods for preserving loquat pulp, but these methods have 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

Embodiment Construction

[0030] According to the following method, utilize the present invention, prepare loquat pulp:

[0031] a. select intact, ripe fresh loquat fruit;

[0032] b. Rinse the selected loquat fruit in rapid flowing water;

[0033] c. Peel the washed loquat fruit, remove the core, and crush it into a pulp. Add 0.3g to 0.8g of color-protecting agent per kilogram of fruit pulp while crushing into pulp;

[0034] d. Add 0.1kg-0.6kg of sugar per kilogram of loquat pulp to prepare, fully dissolve the sugar, and stir evenly with loquat pulp;

[0035] e. Vacuum the stirred pulp to get rid of part of the air in the pulp tissue, and the relative vacuum is 0.05MPa to 0.1MPa;

[0036] f. Heating the loquat pulp to passivate the enzyme activity, the heating temperature is 85°C-95°C, and the holding time is 6 minutes-8 minutes;

[0037] g. the loquat pulp is subpackaged and sealed.

[0038] h. The packaged loquat pulp is placed in cooling equipment for rapid cooling, or it can be cooled by wate...

Abstract

The invention relates to a loquat pulp color fixative and methods for preparing and storing loquat pulp at normal temperature. The color fixative comprises the following components: sodium tripolyphosphate, iso-Vc sodium, sodium pyrosulfite, beta-cyclodextrine and ethylenediamine tetraacetic acid disodium salt. A method for preparing the loquat pulp comprises the following steps of: selecting andflushing fresh loquat fruits; peeling, denucleating and grinding the loquat fruits into pulp; adding the color fixative and white sugar; mixing the components uniformly; vacuumizing the stirred pulp;heating the vacuumized pulp to passivate enzymatic activity; subpackaging and cooling the loquat pulp; putting the cooled loquat pulp in storage; and storing the loquat pulp at normal temperature. The loquat pulp prepared by the method has low storage cost; and the method used in a processing procedure is simple and the loquat pulp can be stored at normal temperature.

Description

technical field [0001] The invention relates to a preparation and room temperature preservation method of loquat pulp, and a color-protecting agent involved in the preparation and preservation. 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 consumed by the public. The drink with loquat pulp as the main ingredient is orange in color. In addition to the functions of ordinary drinks, it also has the functions of nourishing 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 preser...
