Abstract

The invention discloses a curing agent for fruit and vegetable tissues and a preparation method and application thereof, and belongs to the field of fine and deep processing of fruits and vegetables. The curing agent for the fruit and vegetable tissues consists of water, citric acid and a calcium-containing compound, wherein the mass ratio of the citric acid to the water is (1-3):100; the mass ratio of calcium ions in the curing agent to the curing agent is (0.3-2):1000; and the calcium-containing compound is calcium oxide or calcium hydroxide. The application of the curing agent comprises the following steps of: putting the fruits and vegetables into the curing agent for the fruit and vegetable tissues, pre-vacuumizing under reduced pressure or soaking under normal pressure, and then preboiling by using boiling water and rinsing by using clear water so as to fulfill the aims of curing the fruit and vegetable tissues and improving the processability of the fruits and vegetables; meanwhile, the bitterness or peculiar smell of the fruits and vegetables caused by the use of calcium chloride, calcium acetate and the like are avoided.

Description

technical field [0001] The invention relates to the field of deep processing of fruits and vegetables, in particular to a fruit and vegetable tissue solidifying agent and its preparation method and application. Background technique [0002] During the ripening process of fruits and vegetables, the pectin and calcium pectate in the cell wall are gradually degraded under the action of pectinase, resulting in loose structure and tissue softening of some fruits and vegetables such as peaches, apricots, pears, apples, mushrooms, pumpkins, and cantaloupe , As a result, the processing performance of fruits and vegetables such as canning, preserved fruit, dehydration, and quick freezing is poor, which affects the quality and sensory quality of the product. In order to solve this problem, the traditional method is to adopt calcium chloride, calcium sulfate, calcium carbonate, calcium acetate, calcium lactate or calcium propionate to soak and process, but the problem that above-mentio...
