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
The present invention relates to the production method of a kind of nutrition and medicinal products, particularly a kind of pawpaw is through flash distillation and 3 times of supersonic airstream ultralow temperature disintegrating process.
Background technology
Pawpaw have the title of " hundred benefit fruit kings ".Usually the pawpaw of indication has two big types, rosaceae chaenomeles plant pawpaw and tropical fruit (tree) Caricaceae pawpaw (papaya), and rose family pawpaw pharmaceutical usage is unnecessary common daily edible, and papaya then is mainly used in edible.
It is not good that rose family pawpaw is eaten mouthfeel raw, processes the prepared slices of Chinese crude drugs more and use, and has the effect of flat liver Shujin and stomach dampness elimination, is used for the arthritis with fixed pain caused by dampness contraction, the heavy pain of waist knee joint acid, the convulsion of vomiting and diarrhoea, beriberi oedema.Modern constituent analysis shows that pawpaw contains rich dietary fiber and organic acid, especially contain a large amount of vitamin Cs, polyphenols (comprising compounds such as flavonoids, tannin and phenolic acid) and hepatocuprein (Superoxidedismutase, SOD).
Because pawpaw has more nutritional labeling and medicinal ingredient and function, thereby the composition that is used as nutriment and medicine uses more.Pawpaw has rich dietary fiber and pawpaw pectin; But; Dietary fiber is the indispensable material of health diet; Fiber is keeping playing the part of important role on the digestive system health, and absorbing enough fibers simultaneously also can angiocardiopathy preventing, cancer, diabetes and other disease.Fiber can clean wall of digestive and strengthen digestive function, and fiber can dilute and quicken simultaneously the removing of carcinogen and noxious material in the food, the alimentary canal that protection is fragile and prevent colon cancer.Fiber can slow down digestion rate and rapid drainage cholesterol, so can let blood sugar and cholesterol in the blood be controlled at optimal level; A large amount of dietary fibers and pectin also are unfavorable for that the ultramicronising of pawpaw handles, and once have report to adopt enzymolysis or conventional ultra micro air-flow to pulverize, like this or cause loss or the inaccessible complete cell membrane fragmentation of fineness in enzymolysis process of dietary fiber and polyphenoils; Adopt enzyme solution to need material liquid flowization and intensification,, thus can't give full play to its effectiveness.Even if enzymolysis and conventional air-flow ultramicronising combine; Pawpaw through enzymolysis also needs heated drying; It is active to lose its anti-oxidation efficacy once more, and the air-flow ultramicronising in later stage does not demonstrate fully low temperature and keeps active advantage, can't reach the active ultramicronising effect that keeps of high anti-oxidation.
The air-flow ultramicronising is to utilize ultrasonic air-flow dry material to be carried out the new and high technology of physical crushing; But the airslide disintegrating mill of report is many with subsonic speed and 1 overtone speed air-flow jet pipe technology before; The particle diameter of its pulverizing distributes and reaches more than 90% less than the 5-7 micron; Air-flow center transient temperature is about 40 degrees below zero in the crushing process of its reckoning simultaneously, and the particle size range wider distribution can not be guaranteed the broken wall of pawpaw plant cell wall.
Therefore, need a kind of technology that is used for pawpaw is carried out ultramicronising, can reduce the granularity of pawpaw ultra micro powder greatly; Reach the refining losses of minimum degree; Keep pawpaw original nutrition composition and functional components, keep all dietary fiber and the antioxidant contents of fruit, not only reach ultramicronising effect preferably; Can also avoid nutrient loss, and simplify production technology.
Summary of the invention
In view of this, the purpose of this invention is to provide the preparation technology of a kind of high anti-oxidation function ultramicronising pawpaw, can reduce the granularity of pawpaw ultra micro powder greatly; Reach the refining losses of minimum degree; Keep pawpaw original nutrition composition and functional components, keep all dietary fiber and the antioxidant contents of fruit, not only reach ultramicronising effect preferably; Can also avoid nutrient loss, and simplify production technology.
The preparation technology of high anti-oxidation function ultramicronising pawpaw of the present invention may further comprise the steps:
A. directly broken flash distillation is drying fast with pawpaw, directly dryingly is lower than 8% to water content;
B. the dry broken end of the pawpaw of gained among the step a is being lower than under-140 ℃ the temperature and is pulverizing through airslide disintegrating mill, the air velocity of airslide disintegrating mill is crushed to granularity and is the ultra micro powder less than 3 microns greater than 3.08 Mach.
Further, the granularity of the drying broken last particle of pawpaw flash distillation is that water content is lower than 8% less than 3mm among the step a;
Further, among the step b, pulverize in being lower than under-145 ℃ the temperature through airslide disintegrating mill at the dry broken end of pawpaw, is crushed to granularity and is the ultra micro powder less than 3 microns.
The invention has the beneficial effects as follows: the preparation technology of high anti-oxidation function ultramicronising pawpaw of the present invention; Utilize the airslide disintegrating mill tool process combined of flash distillation and many overtones speed (above 3.08 Mach), the pawpaw particle behind the flash-evaporation dehydration is pulverized, fully make plant cell wall breaking; Nutritive effect composition wherein can freely discharge at human body alimentary canal; Need not pass through traditional making beating filter residue or enzymolysis and extraction juice, keep pawpaw original nutrition composition and functional components, and keep all dietary fibers of fruit and the refining losses of antioxidant content minimum degree; This technology can reduce the particle diameter of pawpaw ultra micro powder greatly, and minimum grain size reaches below 2 microns; Adopt the air-flow crushing technology of 3 overtones speed to carry out ultramicronising first, it is subzero below 140 ℃ that air-flow pulverizing instantaneous centre temperature can be arrived, and the particle diameter of its pulverizing can be near submicron order; Optimum particle diameter 2 microns being issued to 90%, and particle size distribution range is less, fully guarantees the broken wall of pawpaw plant cell wall; For the raising rate of digesting and absorbing is made positive contribution, and under lower broken environment temperature advantage, keep more antioxidation activity, therefore; The papaya powder of this prepared is different from traditional extraction spray dried powder process body; Process procedure is few, and is little to the antioxidant composition heat loss, keeps whole pawpaw dry components; Effect is active high, and need not add any processing aid.
