Technology for preparing superfine pawpaw with high anti-oxidation function

Abstract

The invention discloses a technology for preparing superfine pawpaw with a high anti-oxidation function. The technology comprises the following steps of: directly removing nuclei from pawpaw, crushing the pawpaw, performing flash evaporation drying, dehydrating till the water content is less than 8 percent, and crushing the dried pawpaw powder at the temperature lower than 140 DEG C through an airflow crusher of which airflow speed is more than 3.08 Mach till the superfine powder with the granularity less than 3 microns is obtained. By using the technology of combining the flash evaporation and the airflow crusher of multi-times sound velocity (exceeding 3.08 Mach), the original nutritional components and functional components of the pawpaw are kept, the nutritional effect components are easily freely released in human digestive tract, and minimum processing loss of all dietary fibers and anti-oxidation components of the fruits is ensured; the technology can greatly reduce the particle diameter of the superfine pawpaw powder; and compared with the conventional technology for extracting and spray-drying the powder, the technology has the advantages that the link is seldom, the heat loss of the anti-oxidation components is low, all dry substance components of the pawpaw are kept, the effect activity is high and any processing aid is not required to be added.

Description

technical field [0001] The invention relates to a production method of nutritional and medicinal products, in particular to a papaya ultra-low temperature pulverization process through flash evaporation and 3 times supersonic air flow. Background technique [0002] Papaya is known as the "King of Baiyi Fruit". There are two types of papaya commonly referred to, papaya, a plant of the genus Papaya in the Rosaceae family, and papaya (papaya), a tropical fruit. [0003] Rosaceae papaya tastes bad when eaten fresh, and it is mostly used as Chinese herbal medicine. It has the effects of calming the liver and relaxing tendons, harmonizing the stomach and eliminating dampness. Modern component analysis shows that papaya is rich in dietary fiber and organic acids, especially rich in vitamin C, polyphenols (including flavonoids, tannins and phenolic acids) and superoxide dismutase (Superoxidedismutase, SOD ). [0004] Because papaya has more nutrients and medicinal ingredients and...

Problems solved by technology

Fiber can slow down the digestion speed and excrete cholesterol the fastest, so it can control the blood sugar and cholesterol in the blood at the most ideal level; a large amount of dietary fiber and pectin are not conducive to the ultramicronization of papaya. It has been reported that enzymatic hydrolysis Or conventional ultra-micro jet crushing, which may lead to the loss of dietary fiber and antioxidant substances in the enzymolysis process or the fineness is difficult to achieve complete cell wall crushing; the enzymatic hydrolysis method requires the liquid fluidization and heating of the material, so that it cannot give full play to its utility

Even if enzymatic hydrolysis and conventional airflow ultramicronization are combined, the enzymatically hydrolyzed papaya still needs to be heat-dried, and its antioxidant activity will be lost again. The later airflow ultramicronization does not fully reflect the advantage of maintaining activity at low temperature, and cannot achieve high anti-oxidation. Micronization Effects on Retention of Oxidative Activity

[0005] Airflow ultra-micronization is a high-tech technology that uses supersonic airflow to physically pulverize dry materials. However, most of the previously reported airflow pulverizers use subsonic and 1-timesonic airflow nozzle technology, and the particle size distribution of the pulverization can reach more than 90%. Smaller than 5-7 microns, at the same time, it is estimated that the instantaneous temperature of the airflow center during the pulverization process is about minus 40 degrees, and the particle size distribution is wide, which cannot ensure the destruction of the papaya plant cell wall
