Description

A kind of method of quick preparation preboiled rice
Technical field
The invention belongs to grain intensive processing technical fields, and in particular to a method of quickly preparation preboiled rice.
Background technique
Preboiled rice be using paddy as raw material, after cleaning, immersion, boiling, drying and the processing such as cooling, then shell pearling and The product obtained, have the advantages that general rice is incomparable: (1) nutrition is comprehensive: preboiled rice is in hydro-thermal process, in cortex and embryo B family vitamin and the water-soluble substances such as inorganic salts with moisture penetration to endosperm inside, increase its vitamin B1 and B5 content By about one time, the content of calcium, phosphorus and iron compared with precision general rice the same as also increaseing accordingly;(2) absorption easy to digest: the shallow lake of preboiled rice Powder is thermally treated to fragment into dextrin, and dextrin content is five times of general rice, human consumption's absorptivity ratio of parboiled rice rice protein Common rice is high by 4.5%, and it is edible to be suitable for infant, patient and old man;(3) rice milling yield is high, ripe rice rate is high, rice bran oil yield is high: Preboiled rice is handled through boiling, improves the structural mechanical properties of seed, and broken rice rate is substantially reduced when pearling;The processing of boiling simultaneously Improve the cooking property of the grain of rice, dilatancy improves, and residual solid content is few, while having the flavour of preboiled rice;Parboiled rice rice bran Due to heat treatment so that protein denaturation is more complete, oil extracted from rice husks is easy to be precipitated, so that oil yield is higher than ordinary rice bran;(4) it stores Good stability: preboiled rice kills most microorganisms and pest in hydro-thermal process, and enzyme denaturation inactivates, thus in storage Stability with higher.
Traditional preboiled rice production technology, including the technological process of production below: paddy is cleared up, is classified, and is impregnated, vapour It steams, dry cooling, husking shelling, pearling and finished product packing.It can be seen that the preparation of preboiled rice is to soak using paddy as object to it Steep individual composition.Due to the presence of rice husk, in conventional processes, the moisture of heat soaking and steam is difficult to penetrate into, process time It is long, waste thermal energy.
Traditional preboiled rice preparation is using high temperature infusion method, i.e., paddy is soaked in 3.5 in 55~70 DEG C of hot water~ 4.5h, so that paddy final moisture content reaches 34%~36%.Decatize is carried out to paddy after immersion, decatize is preboiled rice processing The key link of process, i.e., certain temperature, pressure steam condition under decatize for a period of time, do not make rice starch sufficiently and not Excessively gelatinization.So technique is cumbersome, long processing time, energy consumption cost height becomes the problem of preboiled rice processing.
Summary of the invention
The object of the present invention is to provide a kind of methods of quickly preparation preboiled rice, not only greatly shorten the processing time, simplification Treatment process, and improve the nutrition organoleptic attribute of preboiled rice has less energy consumption, that process is simple, pollution-free, quality is good etc. is excellent Point.
In order to achieve the goal above, the technical solution adopted by the present invention are as follows: the method for this quick preparation preboiled rice, including Following steps:
(1) removal of impurities classification: paddy is cleared up, is cleaned, obtains good paddy after classification processing;
(2) super-pressure immersion treatment: paddy obtained by step (1) is placed in polyethylene retort pouch, after adding water, uses sealing machine Sealing is placed in extra-high tension unit and carries out super-pressure immersion treatment;
(3) paddy obtained by step (2) three-stage microwave treatment: is subjected to segmented microwave treatment, first segment microwave treatment For rice starch gelatinization, second segment microwave treatment is paddy predrying, and third section microwave treatment is rice drying;
(4) sealed package: husking husk rice is carried out after cooling down to paddy obtained by step (3), sealed package is up to product Preboiled rice.
Further, the mass ratio of the water and paddy that add in the step (2) is 1.5:1.
Further, the super-pressure immersion treatment time is 600-1200s in the step (2), including is pressurized and is depressured Process.
Further, the pressurization time is 60-120s, dip time 4s.
Further, the pressure of the ultra high pressure treatment is 300MPa or 400Mpa.
Further, the ultra high pressure treatment is formed using one or several microwave generators of any power Microwave treater, the power of microwave treater are 100-800W.
Further, the microwave frequency that first segment microwave treatment uses in the step (3) for 2450MHz or 915MHz, power 500-1200W, the microwave action time be 500-1000s, the microwave frequency that second segment microwave treatment uses for 2450MHz or 915MHz, microwave power 100-300W, microwave action time 8-10min, third section microwave treatment use micro- Wave frequency rate is 2450MHz or 915MHz, microwave power 100-300W, microwave action time 10-15min.
Further, third is carried out again after needing tempering 40-60min after second segment microwave treatment in the step (3) Section microwave treatment.
Further, paddy moisture after paddy is slowly dried is stated in the step (3) is down to 18%-22%;Paddy is fast Brown rice moisture is down to 14% or less safe grain storage moisture after rapid-curing cutback is dry.
The technical effects of the invention are that: the method for this quick preparation preboiled rice, using super-pressure and microwave technology come Instead of immersion and decatize link, is impregnated by super-pressure, not only reach the moisture content of paddy 34%~36%, paddy outer layer nutrient is migrated to endosperm, and the rice starch that can make under high pressure generates part It is gelatinized phenomenon, the heat effect of subsequent first segment microwave makes rice starch generate adequately gelatinization, forms the distinctive matter of preboiled rice Ground and characteristic, second segment, third section microwave treatment can be dry by paddy carry out portion.Therefore super-pressure immersion treatment, compared to Traditional preboiled rice preparation, not only greatly shortens the processing time, simplifies treatment process, but also improve the nutrition sense organ of preboiled rice Characteristic has many advantages, such as that less energy consumption, process are simple, pollution-free, quality is good.
