Processing method for soft prickly pear cans

Abstract

The invention discloses a processing method for soft prickly pear cans. Firstly, thorns of prickly pear are removed; the prickly pears are peeled to obtain pulps; the pulps are put in citric acid solution for color protecting; canned sugar water containing saccharose, calcium lactate and citric acid is prepared, boiled for disinfecting, and cooled to be at the normal temperature; the pulps are put in high-pressure-resistant compound bags; the rest parts are added to the canned sugar water, and sealed to obtain pre-packaged soft cans; the pre-packaged soft cans are put in a superhigh-pressure disinfector, are pressurized to be under 10-20 MPa; the state is kept for 5-9 minutes; the pre-packaged soft cans are pressurized to be under 200-500 MPa at 65-85 DEG C for the second time for superhigh-pressure disinfection; after the pressure is relieved, the soft cans are taken out for cooling to obtain the soft prickly pear cans. The processing method solves the problem of the pulp tissue is soft and pulpy duo to the thermal disinfection technique, and provides the high-quality wild fruit can product with a good taste, a unique flavor, various nutrients and a health-care effect; the achievement of large-scale production for the technique process is easy; obvious practicability and economy are achieved.

Description

technical field [0001] The invention relates to a production method of canned fruit, in particular to a processing method of soft canned edible prickly pear fruit, belonging to the field of food industry. Background technique [0002] Since mankind entered the 1990s, an upsurge of eating wild flowers and wild fruits has risen internationally, and the development of cactus food is one of them. [0003] Cactus is a perennial evergreen succulent herbaceous drought-tolerant plant that mostly grows in the Gobi or desert. The leaves have become needle-shaped to adapt to the hot weather. Among the many cactus plants, except for a few, most of them are non-toxic cactus. It is not only an ornamental plant, but also a good vegetable and fruit. There are more than 2,000 species in the world, and Mexico's cacti account for about half of the world's cacti species, enjoying the reputation of "the world's cactus kingdom". In my country, wild cactus is distributed in Fujian, Guangd...

AI Technical Summary

Problems solved by technology

The research results show that the canned prickly pear fruit produced under such conditions has turbid sugar water, soft and rotten pulp, poor flavor, and high temperature is easy to cause a large loss of vitamins rich in prickly pear fruit

[0006] At present, many canned products on the market have lost a lot of nutrients after being processed by conventional heat processing technology, especially after high-temperature sterilization of vitamins, almost all of them are lost.

There are also some manufacturers who add nutritional supplements to their products. However, the survey found that adding a large amount of vitamin supplements will have an adverse effect on the taste and taste of canned food or food. The addition of vitamin supplements will cause metallic taste, fishy smell, etc. unpleasant taste
