Embodiment 1

[0011] Embodiment 1: a kind of production method of ultra-high pressure canned lotus seed, comprises the following steps:

[0012] (1) Select fresh lotus seeds with full grains and no browning, cored or quick-frozen lotus seeds without cores, wash and drain the selected lotus seeds, and send them to high-pressure equipment for 60 minutes at 500MPa ultra-high pressure per 100g of lotus seeds;

[0013] (2) Put the ultra-high pressure treated lotus seeds into cans, add sugar water, heat and exhaust, seal the cans, sterilize, and cool down to obtain canned lotus seeds. The sugar water is formulated with 15% rock sugar and 0.02% citric acid, and a small amount of other food additives can also be added.

Embodiment 2

[0014] Embodiment 2: a kind of production method of ultra-high pressure lotus seed can, comprises the following steps:

[0015] (1) Select fresh lotus seeds with full granules and no browning, or quick-frozen lotus seeds with core removed, wash and drain the selected lotus seeds, and send them to high-pressure equipment for 30 minutes at 600MPa ultra-high pressure per 100g of lotus seeds;

[0016] (2) Put the ultra-high pressure treated lotus seeds into cans, add sugar water, heat and exhaust, seal the cans, sterilize, and cool down to obtain canned lotus seeds. The sugar water is formulated with 10% rock sugar and 0.04% citric acid, and a small amount of other food additives can also be added.

[0017] The process described in the above embodiments, including canning, adding sugar water, heating and exhausting, sealing, sterilizing, and cooling are all general processing techniques for canned food production.

[0018] The invention adopts ultra-high pressure technology to pr...

Abstract

The invention provides a production method of an ultrahigh pressure lotus seed can. Pretreatment is carried out on lotus seeds by an ultrahigh pressure technique to prevent the lotus seeds from surviving; and under the action of ultrahigh pressure effect, starch granules in the lotus seeds generate certain degradation and degeneration in the gelatinization process, and is highly mixed with other substances in cells, so that recrystallization of lotus-seed starch molecules in the storage process of the lotus seed can is effectively prevented, so as to prevent survival of the lotus seed can. The production method is low in equipment requirements and high in operability; the problem of survival of high-starch cans of lotus seeds and the like can be effectively solved. The production method is suitable for industrialized large-scale production of the lotus seed can.

Description

technical field [0001] The invention relates to a production method of canned lotus seeds with sweet taste, in particular to a production method of ultra-high pressure canned lotus seeds. Background technique [0002] Canned food is more and more popular in our daily life. No matter what kind of canned food is processed through raw material processing, cooking, canning, sterilization and other processes, canned food is also different according to different raw materials. There are Canned fruits, canned meat, canned aquatic products, canned vegetables, canned edible fungi, etc. Some people think that canned food is not nutritious and unsafe, but it is not. After a certain process of processing and sterilization, canned food retains the nutrients in the raw materials, and it is hygienic and healthy, and it is more convenient to eat. Moreover, canned food has one of the best advantages compared with other foods, that is, it can be stored at room temperature without losing fr...
