Problems solved by technology

Most of the existing jujubes are used as instant fruits. When the fruit period is over, the fruits are discarded, resulting in a waste of resources. Processing jujubes into food that can be eaten for a long time improves the shelf life and application value of jujubes

Abstract

The invention discloses a processing method of honeyed preserved Indian jujube, characterized in that honeyed preserved Indian jujube is made with Indian jujube, and the Indian jujube is processed via the steps such as preparing, crispness-keeping hardening, sulfur treatment, preboiling, boiling with sugar, drying, gumming, packaging, and inspecting. Crevices are made on the surface of Indian jujube, it is easier for sugar solution to enter tissue cells of Indian jujube, and by adding edible salt in preboiling with honey solution, it is possible to improve internal tissue structure of Indian jujube, change permeability of cells and facilitates seepage of sugar in the preserved Indian jujube; therefore, the preserved jujube has pure and delicious flavor and stable color and has the effects such as cooling and detoxifying, cleaning blood, promoting digestion, and maintaining beauty.

Description

technical field [0001] The invention relates to the field of food deep processing, in particular to a processing method for honey-made jujube preserved fruit. Background technique [0002] Maoye jujube: Also known as Indian jujube, Taiwan green jujube, etc., it belongs to the fruit tree of the genus Jujube in the family Rhamnaceae. Because it is produced in India, it is named Indian jujube, and because its fruit shape resembles an apple, Maoye jujube is also called "tropical apple". Every 100 grams of jujube contains 1.2 grams of protein, 0.3 grams of fat, and 23.7 grams of carbohydrates. It is rich in vitamins and various trace elements. It has the functions of cooling and detoxifying, purifying the blood, promoting digestion, and beautifying the skin. Most of the existing jujubes are used as instant fruits. When the fruit period is over, the fruits are discarded, resulting in a waste of resources. Processing jujubes into food that can be eaten for a long time improves th...
