Abstract
The invention relates to the fruit processing field, and relates to a wild hawthorn freeze-dried powder and standards. Freeze-drying comprises the steps: freezing a fruit pulp for 12 h, then putting in a freezing drier, and when the material temperature is dropped to -40 DEG C or less, starting a vacuum pump; when the product temperature rises to 0 DEG C, rising the pressure to 30 Pa, and when the temperature rises to 40 DEG C, finishing freeze-drying; taking frozen fruit slices, putting into a vacuum oil bath dewatering machine with the vacuum degree of 0.08 MPa, and drying; and then carrying out coarse crushing, superfine crushing, vacuum packaging and sterilization. Through testing, the moisture content is not more than 9.0%, the total acid content is not more than 8.0 g/100 g, the total arsenic content is not more than 0.5 mg/kg, the cadmium content is not more than 0.05 mg/kg, the lead content is not more than 1.0 mg/kg, the patulin content is not more than 50 [mu]g/kg, the total number of bacterial colonies is not more than 1000 cfu/g, the number of coliform is not more than 30, and the number of mould is not more than 50 MPN/100 g. The wild hawthorn freeze-dried powder has the characteristics of being small in nutrient loss, good in fruit powder processing effect, and convenient to eat in different seasons.
Description
Technical field
The present invention relates to fruit process field, i.e. Wild Hawthorn freeze-dried powder and standard.
Background technology
Wild Hawthorn (NipponHawthornFruit) has another name called duckweed fruit, large red pieces etc.Suitable growth, in endroit or mountain region bushes, in being born in height above sea level 250m-200m rice mountain valley or mountain region bushes, is gathered during fruit maturation in autumn more, puts dry after slightly scalding in boiling water or convection drying.Medicinal effects: the equal hyoscine of stem, leaf, fruit and fruit stone, fruit is in the 9-11 month, and stem can be adopted at any time, and Ye Chunxia gathers autumn.Function: stomach invigorating disappears long-pending, astringing to arrest bleeding, blood stasis removing analgesic.Changbaishan area Wild Hawthorn resource is very abundant, but its product is still rare, short in collecting season storage life, can not meet the consumption demand of Various Seasonal, seriously constrains the comprehensive exploitation of Wild Hawthorn.
Summary of the invention
The object of the invention is to provide a kind of for above-mentioned deficiency and hawthorn is carried out deep processing, nutritive loss is little, and fruit powder processing effect is good, the Wild Hawthorn method for preparing freeze-dried powder that nutritive index is definite and standard.
Technical solution of the present invention is: Wild Hawthorn method for preparing freeze-dried powder, and its step is as follows:
(1) select materials: ripe hawthorn fresh fruit of gathering, extract carpopodium, fruit stone and chankings.
(2) blanching is softened: be placed in steamer by the haw berry rinsed well, heats 8 minutes at 90 DEG C.
(3) stoning: crushed by fruit, is broken into flat with fruit and seed is intact does not break for good, realizes stoning.
(4) pull an oar: crushing and beating is carried out to haw berry, simultaneously by hawthorn pulp homogeneous.
(5) freeze drying: by freezing for pulp 12h, put into freeze drier afterwards, when temperature of charge is down to below-40 DEG C, opens vavuum pump; When product temperature rises to 0 DEG C, raised pressure is to 30Pa, and when temperature rises to 40 DEG C, freeze-drying terminates; Get freezing after chankings to put into vacuum be that the vacuum oil bath dewaterer of 0.08MPa is dry.
(6) coarse crushing: be crushed to 80 order fruit powder.
(7) ultramicro grinding: the haw berry powder of coarse crushing is put into micronizer and pulverizes, obtains the ultra-fine haw berry powder of 200 order, more namely drying obtains hawthorn and freeze dry powder.
(8) vacuum packaging: the haw berry powder obtained is carried out vacuum seal packaging.
(9) sterilizing: hawthorn is frozen dry powder at 121 DEG C, moist heat sterilization in 15min steam.
After testing: moisture≤9.0%, total acid≤8.0g/100g, total arsenic≤0.5mg/kg, cadmium≤0.05mg/kg, lead≤1.0mg/kg, patulin≤50ug/kg, total plate count≤1000cfu/g, coliform number≤30, mould≤50MPN/100g.
Advantage of the present invention is: its advantage of (1) the present invention is that raw materials for production are easily got, and makes simple, instant, delicious flavour, sweet and sour taste, nutritious, is a kind of good drink and food additive.(2) be that directly quick-frozen, vacuum drying are carried out to raw material, without natural air drying and heated-air drying, compared with the products such as traditional drying hawthorn, this desivac can retain preferably and concentrate the multiple nutrients composition in fresh sample, as sugared part, vitamin, cellulose and mineral matter etc., farthest maintain nutrition and the local flavor of raw material.(3) in process, do not use any additive, make product be provided with pollution-free, non agricultural chemical residuum, the qualitative character of pure natural.(4) adopt new technology hawthorn processing achievement powder, improve the storage property of product, convenient transportation, sweet and sour taste, develop body-building nutrient food that the four seasons suit the taste of both old and young thus improve the utilization rate of Hawthorn Resources.(5) there is the advantages such as technique is simple, easy to operate, production cost is low, be applicable to suitability for industrialized production.Hawthorn is carried out deep processing, has nutritive loss little, fruit powder processing effect is good, is convenient to the advantage that Various Seasonal is edible.(6) quality index science, rationally, secure.
Below in conjunction with embodiment, embodiments of the present invention are described in further detail.
