Abstract

The invention discloses a preserved roselle manufacturing method which comprises the following steps of preparing materials, salting the materials, protecting crispness of the materials, hardening the materials, sulphuring the materials, precooking the materials, sugaring the materials, drying the materials, reshaping the materials, packing the materials and the like. Roselle is salted to remove part of water, so that tissues of the roselle are compact, the permeability of cells is changed, and sugar can permeate into preserved roselle conveniently. Thus, the preserved roselle is pure in flavor, delicious in taste and convenient to eat. Furthermore, nutrients of the roselle are fully kept. The preserved roselle has the effects of relieving summer heat, reducing blood pressure, intensifying blood vessel elasticity, curing hypertension, clearing heat, detoxifying, helping digestion, helping produce saliva and slaking thirst.

Description

technical field [0001] The invention relates to the field of food deep processing, in particular to a method for preparing preserved roselle fruit. Background technique [0002] Roselle: also known as roselle, roselle, mountain eggplant, etc., is an annual herb of the genus Hibiscus in Malvaceae. The calyx of roselle is a fleshy structure, juicy, rich in protein, organic acids, vitamin C, and various Amino acids, a large amount of natural vitamins and minerals needed by the human body, are beneficial to regulate and balance blood lipids, promote calcium absorption, promote children's development, suppress lungs and cough, relieve alcohol, promote digestion, cool and detoxify water, lower blood pressure, etc. . It is widely used in high-grade beverages, cold drinks, soft drinks, iced tea, hot tea and other foods or drinks. For example, the invention patent with application number 200610170544.8 discloses a production process of vanilla roselle preserved fruit, providing a co...
