Preparation method of hypoglycemic bitter melon freeze-dried powder

Abstract

The invention discloses a method for preparing bitter gourd freeze-dried powder capable of reducing blood glucose. The method comprises the following steps that: A, bitter gourd fruits are washed clean; B, the tissue of bitter gourd fruit is fully broken at a temperature below 30 DEG C so as to fully release intracellular matter and obtain bitter gourd fruit paste with pulp; C, a complex enzyme preparation E1 which has pectinase and cellulose enzyme complexes as components and the bitter gourd fruit paste are mixed in a stir-type enzyme reactor, and react for 1.5 to 2 hours at a temperature of between 45 and 55 DEG C; the pH value is controlled between 4 and 5; a complex enzyme preparation E2 comprising bacterial protease and glucoside hydrolytic complex enzyme is added and reacts with the complex enzyme preparation E1 and the bitter gourd fruit paste for 0.5 to 1 hour at a temperature of between 40 and 60 DEG C; the pH value is controlled to be between 5.5 and 7; and then the temperature is adjusted to be between 75 and 85 DEG C and kept for 15 and 20 minutes so as to inactivate the complex enzyme preparations; and D, the fruit paste after enzyme treatment is concentrated for 3 to 4 hours in a vacuum dryer at the vacuum degree between 1 and 5 kPa and at a temperature lower than or equal to 45 DEG C so as to remove most of moisture, and then is freeze-dried in a freeze dryer under the pressure lower than 10 Pa and at a temperature lower than 20 DEG C so as to obtain the bitter gourd freeze-dried powder. The bitter gourd freeze-dried powder obtained by the method has the advantage of good effect of reducing blood glucose.

Description

Technical field [0001] The present invention relates to a production method of a hypoglycemic assisted food, and is specifically a method of preparing a sugar-flare of bitter gourd. Background technique [0002] Studies have shown that bitter gourd contains a large amount of flavonoids (steroids and triterpenoid saponin), and the hypoglycemic active ingredient such as insulin can be developed into auxiliary food to diabetes treatment. Currently, the World Health Organization (WHO) report has been as high as 160 million patients with diabetes in 2000. There are about 50 million patients with diabetes in my country, and the number of diabetic patients is second only to the second place in India. Regarding the treatment of diabetes, the International Diabetes General Assembly put forward the "modern integrated therapy" - dietary health treatment, exercise treatment, drug treatment, self - monitoring, knowledge education and psychotherapy. This determines the important role of hypogl...

Problems solved by technology

While the bitter melon fruit has been broken into pulp on the surface during the crushing process, but in fact only some of the cells are broken, and a large number of cells are not broken, so a large amount of effective substances are distributed in the unbroken cells without being released.

The human digestive system cannot decompose pectin and cellulose, so a large number of active ingredients cannot achieve their due medicinal effects

Second, bitter melon contains a variety of plant proteins and polypeptides (such as plant insulin, etc.), as well as flavonoids, saponins (steroidal saponins and triterpene saponins) and other active ingredients that need to be modified to a certain extent to have a better hypoglycemic effect , and direct crushing and freeze-drying cannot further modify these active ingredients, so its proper hypoglycemic effect has not been discovered
