Description

The processing method that a kind of buckwheat bakees rice
Technical field
The processing method that a kind of buckwheat bakees rice, belongs to food processing technology field, and in particular to one kind pressurization, heating Joint processing technology, finally obtains free from extraneous odour, with rice there is identical cooking property buckwheat to bakee rice.Through working process of the present invention Bright in color, fluffy adhesion during rear buckwheat boiling, give off a strong fragrance, good mouthfeel, largely retain rutin etc. many Phenolic compounds activity, reduces the loss of lysine, dietary fiber and resistant starch, the time for delaying rice aging to bring back to life.
Background technology
Buckwheat is the crop of buckwheat, annual herb plant.Buckwheat is rich in six big nutrition needed for human body body Element, its content is respectively protein 7.94%~17.15%, fat 2.00%~3.64%, starch 67.45%~79.15%, Cellulose 1.04%~1.33%.Containing eight kinds of essential amino acids in buck wheat protein, particularly lysine and arginine contains Amount is above general large cereal crops.Protein utilization is protein utilization in 79.9%, duck wheat in general buck wheat Rate is 77.6%, and the protein utilization than wheat, oat is high.Starch can be divided into rapid digestion starch, slowly disappear in buckwheat Change starch and resistant starch, wherein resistance starch content accounts for the 33%~38% of total starch content, it is to reducing human body blood after the meal The rise of sugar has obvious effect, and it can influence insulin secretion, improves lipid conformation, is the preferred starch of diabetic Food.Water-soluble dietary fiber accounts for total dietary fiber 20%~30% in buckwheat dietary fibers, and it is to human serum T-CHOL And there is LDL-C content obvious reduction to act on, and be the health food materials of dietotherapeutic.Macro minerals content in buckwheat Other cereal crops are above, for example, magnesium is 0.22%, much larger than in 0.051% magnesium content, rice in wheat 0.063% Magnesium content.Meanwhile, boron, iodine, cobalt, selenium and other trace elements are also contained in buckwheat, wherein selenium contributes to the row of human body noxious material Remove, regulation immunity and anti-cancer, anti-aging effect.Except above-mentioned nutriment, buckwheat is also rich in substantial amounts of polyphenol substance, its Middle rutin accounts for 70%~90%, peculiar by buckwheat.Rutin has the pharmacological action of inoxidizability, can reduce capillary and lead to Permeability and fragility, the normal elasticity for keeping and recovering capillary.In addition, it also has anti-inflammatory, diuresis, the effect of antibechic, It can be clinically used for preventing and treating cerebral hemorrhage, retinal hemorrhage, its derivative has treatment burn, arthritis and various vascular diseases Special efficacy.Therefore, buckwheat is a kind of health food resource with high value of exploiting and utilizing.
Buckwheat is acted on special food treatment of food therapy, protected in modern safety as the green coarse cereals of generally acknowledged pollution-free natural There is critical role in health food.But buckwheat process product only accounts for 20%~30% of yield or so, it is mainly in raw grain form Sold.Because China's further processing of grains level is low, simple processing has only been carried out without critical technological innovation, buckwheat is caused Wheat resource does not accomplish to make the best use of everything.Buckwheat raw grain product coarse mouthfeel, idiotrophic material are lost in seriously, far can not meet people To nutrition, delicious food, quick and easy consumption demand.
Point of penetration is left present invention is generally directed to the cooking property in the processing of buckwheat rice and nutritional ingredient, carries out work Skill is reformed and improvement.Research shows, buckwheat its physicochemical property, nutritional ingredient and functional activity in the process such as heat treatment Material can change, and the difference of different processing technologys and processing sequence can produce great otherness.Making buckwheat rice During, if extension heat time and increase heating-up temperature can cause subtracting for rutin content while buckwheat rice mouthfeel is improved It is few, and deepen buckwheat color and luster;In high voltage driving IC buckwheat, total phenol content reduction, alpha-amylase activity can be suppressed, but Antioxidation activity, α-glucose glycosidase activity inhibiting rate and ACE maximum inhibitions can then be improved;Enter to heat treated buckwheat Row constituent analysis is found, the formation of resistant starch in buckwheat is can help to during high pressure and rapid cooling.In addition, research Show that pressurization can be conducive to the reinforcing of dietary fiber in buckwheat.Based on the above theoretical foundation, this technique using a kind of pressurization, A kind of mode that heating joint processing technology is pre-processed as buckwheat, by controlling starch gelatinization and protein denaturation degree, promotees Buckwheat is obtained and rice identical cooking property, and preferably retain lysine and arginine, polyphenol content, be conducive to meals The reinforcing of fiber, keeps polyphenoils activity.Buckwheat rice bright in color after being processed through postorder, fluffy adhesion, fragrance Strong, good mouthfeel, and delay the generation of rice aging.
The content of the invention
The object of the invention:It is lost in for the nutriment that buckwheat rice exists in process, coarse mouthfeel and starch Aging phenomenon, develops the processing method that a kind of buckwheat bakees rice.Buckwheat after being processed through present invention process has and rice Identical digestion time, its meal coloured light is bright, fluffy adhesion, give off a strong fragrance, good mouthfeel, largely retain rutin etc. many Phenolic compounds activity, reduces the loss of lysine, dietary fiber and resistant starch, delays rice aging.
Technical scheme:The processing method that the present invention bakees rice for a kind of buckwheat.It comprises the following steps:(1) screening is with removing It is miscellaneous:Fresh buckwheat raw material is taken, the grain of rice for remove sand, going mouldy and rotting;(2) pressurized, heated is handled:By obtained by step (1) Buckwheat is placed in pressure processing equipment, and application pressure is 25~35min of processing at 0.1~0.2Mpa, 105~115 DEG C of temperature. (3) drying and processing:Buckwheat is placed in drying box after heating pressurized treatments, and low temperature drying is carried out under conditions of 60 DEG C to moisture Content 12%~14%.(4) post-process:Cooled down after drying and processing, dry vacuum packaging, be i.e. acquisition has identical with rice The buckwheat of digestion time bakees rice.
The method that the buckwheat of the present invention bakees rice, has the advantages that:
(1) processed buckwheat has digestion time identical with rice, can make an addition to and boiling simultaneously is carried out in rice.Its It is in good taste, have chewy texture, free from extraneous odour;In sensory aspect:Bright in color, fluffy adhesion, give off a strong fragrance, good mouthfeel.
(2) in terms of nutritional ingredient:Largely retain the polyphenolic substances such as rutin activity, reduce lysine, meals The loss of fiber and resistant starch, delays the generation of rice aging.
