Description
Technical field
The present invention relates to a kind of processing method of okra, specifically a kind of preparation method of okra fruit powder.
Background technology
State Intellectual Property Office discloses on January 23rd, 2013 patent document that publication number is CN102885158A, patent name is the preparation method of a kind of soybean fruit powder, patent document is raw material by fresh soybean, carry out screening, clean, segment, then squeeze the juice, filter, concentrate, add maltodextrin as homogeneous after drying aid, finally carry out spraying dry with press spray drier, obtain the soybean fruit powder of foresythia, not only remain the peculiar nutriment of soybean, and product dissolubility is good, special taste.The present invention has the advantages such as product quality is high, technique is simple, production cost is low, is applicable to suitability for industrialized production.
State Intellectual Property Office is a kind of patent document of drying processing method of okra in disclose publication number be CN103636746A patent name on March 19th, 2014, and patent document comprises: classification of selecting materials, washing impurity elimination, steam blue or green process, dry dry, micro-wave vacuum, package storage, Product checking.The present invention adopts and steams blue or green process before micro-wave vacuum, can effectively various enzymatic activity, the to greatest extent original color and luster of reservation okra in passivation okra cell; Meanwhile, steam the blue or green content that effectively can retain okra Determination of Chlorophyll, glue polysaccharide and flavones in conjunction with micro-wave vacuum process, improve the quality of okra dried product to greatest extent.The present invention, without the need to carrying out cutting process to raw material, keeps the integrality of okra tissue, easy and simple to handle, and safety and environmental protection can realize continuous, automation cleaner production.
Okra, another name gumbo folder, swordweed are the annual herbaceous plant of Malvaceae, fruit contains higher protein, vitamin and mineral matter, not storage tolerance, suitable fast freight marketing fresh, easily blackening again after scratch in transport, at relatively high temperatures will old and feeble, yellow so that putrid and deteriorated.The converted products of current okra mainly contains edible vegetable, the processing of okra jasmine tea, milk powder batching, gumbo pectin product etc.Because the seasonality of okra is strong, unsuitable fresh-keeping after adopting, therefore okra is carried out deep processing, the nutritional labeling of okra can be retained to large extent, employing spray drying technology prepares the deficiency that okra fruit powder can make up gumbo processed goods on market preferably, okra fruit powder can retain the original local flavor of okra and nutritional labeling to greatest extent, meets the needs of people to okra simultaneously, and therefore spraying dry processing okra fruit powder has good exploitation prospect.
Through retrieval and investigation, also do not find okra fruit powder and preparation method thereof, and the technical scheme of above-mentioned patent is different with the technical scheme of this patent.
Summary of the invention
The object of this invention is to provide the preparation method of a kind of okra fruit powder, this preparation method remains nutrition and the health care composition of okra, and under the okra made fruit powder normal temperature, instant capacity is better, can retain original flavour nutrient to greatest extent simultaneously, be easy to absorb, instant.
For achieving the above object, the technical solution adopted in the present invention is:
A preparation method for okra fruit powder, this preparation method comprises the following steps: A, okra drying and crushing: will clean okra hour pulverizing after 55o ~ 65o drying 10 ~ 14 of drying; B, enzymolysis: the okra after pulverizing and deionized water are added deionized water in the ratio of 1g:80mL, stir, the cellulase of slurry weight 0.2% ~ 0.6% and the pectase of slurry weight 0.1% ~ 0.3% is added in slurries, hydrolysis temperature is 50o ~ 55o, and enzymolysis time is 1.0 ~ 2.0 hours; C, filtration: vacuum filtration is carried out to the slurries after enzymolysis; D, allotment: in slurries after filtration, add drying aid, described drying aid is the maltodextrin of this slurry weight 5% ~ 10%; E. spraying dry: utilize spray dryer to carry out drying to the slurries after allotment, the dry inlet temperature of spray dryer internal spraying is 160o ~ 170o, makes okra fruit powder.
In the present invention, use cellulase or pectase individually, or the cellulase added in slurries and the ratio of pectase be not within described scope, or in allotment, the drying aid added is not maltodextrin, or the drying aid added is maltodextrin, and ratio not within described scope time, the instant capacity of the okra fruit powder finally obtained is all not good, wants 6 ~ 10 minutes ability to be all dissolved in the water under normal temperature.
In the present invention, enzymolysis step adopts the mixed enzyme of cellulase and pectase, adaptation step adopts drying aid to be maltodextrin, and in described proportion, this enzymolysis step and adaptation step coordinate, serve beyond thought effect: under comparable conditions, instant capacity is very good, can all be dissolved in the water under normal temperature in 0.5 ~ 1 minute.
Further, in described steps A, clean the okra dried and pulverize after 60o is dry 12 hours.
Further, in described step B, in slurries, add the cellulase of slurry weight 0.4% and the pectase of slurry weight 0.2%
Further, in described step B, hydrolysis temperature is 53o.
Further, in described step B, enzymolysis time is 1.5 hours.
Further, in described step D, described drying aid is the maltodextrin of this slurry weight 7.5%.
Further, in described step e, spray dryer internal spraying hothouse is adjusted to 165o.
Beneficial effect of the present invention: owing to adopting above-mentioned technical scheme, have processing preparation simple, equipment is easy to get, the feature that production cost is low; With the okra fruit powder that the inventive method is obtained, instant capacity is good, can all be dissolved in the water under normal temperature in 0.5 ~ 1 minute, can retain local flavor and the nutritional labeling of okra to greatest extent simultaneously, meet again the needs of people to okra simultaneously, there is good exploitation prospect.
