Selenium-rich mopan persimmon jam and preparation method thereof

Abstract

The invention discloses a selenium-rich mopan persimmon jam and a preparation method thereof. The preparation method comprises mopan persimmon pretreatment, hippophae rhamnoides L. pretreatment, alpinia officinarum Hance pretreatment, homogenization, concentration, sterilization and packaging. Compared with the prior art, the technical scheme comprises the following advantages: alpinia officinarum Hance is hot in nature and is capable of effectively supplementing cold property of mopan persimmon; the jam is prepared by matching alpinia officinarum Hance with hippophae rhamnoides L., and is fine in taste and abundant in nutrition, and the selenium content reaches 2.85-4.35 mu g / Kg; and during pretreatment of mopan persimmon, by immersing mopan persimmon in a sodium pyrosulfite solution and performing high-temperature boiling for destroying tannic acid in mopan persimmon, influence of mopan persimmon on human body mineral matter absorption is reduced, and also cardiovascular and cerebrovascular diseases are effectively controlled and body immunity is improved.

Description

technical field [0001] The invention belongs to the technical field of selenium-enriched food processing, and in particular relates to a selenium-enriched mopan persimmon jam and a preparation method thereof. Background technique [0002] Selenium is one of the essential trace elements for the human body. Selenium-rich foods have anti-cancer and anti-radiation effects, which are very beneficial to human health. However, due to the lack of selenium in many domestic lands, many people's daily selenium intake is low. Insufficient intake leads to the need to increase the selenium content in daily food through effective methods. [0003] Mopan persimmon contains 0.31 micrograms of selenium per 100g of pulp, and its vitamins and sugar content are 1-2 times higher than that of ordinary fruits. Improve cardiovascular function. Although persimmons have many benefits to the human body, because persimmons contain more tannic acid and pectin, if eaten on an empty stomach, large and va...

Problems solved by technology

Although persimmons have many benefits to the human body, because persimmons contain more tannic acid and pectin, if eaten on an empty stomach, large and varying lumps will form under the action of gastric acid, forming stones. Calcium, zinc, magnesium, iron and other minerals in persimmons form compounds that cannot be absorbed by the human body, so that these nutrients cannot be used. Therefore, eating too much can easily lead to the lack of these minerals. There are many reasons why persimmons are delicious but not too much. Nutrient-rich persimmons can only be wasted in vain, so a method is needed to remove or modify the tannic acid in it, so as to eliminate some adverse reactions caused by it, and increase its shelf life by making jam
