Description

A kind of konjak (Moyu) rice and production method thereof
Technical field
The present invention relates to food processing technology field, particularly relate to a kind of method for producing of konjak (Moyu) rice.
Background technology
Konjaku is the underground spherical tuber of Araeceae Amorphophallus herbaceos perennial, and main product is in Southwest Mountainous Areas.Find after deliberation and confirm, the special composition " glucomannan " in konjaku has anti-cancer and cancer-preventing, expansion capillary, reduce blood pressure, cholesterol, increase HDL, reduce the fasting blood-glucose of diabetes patient, excited enteron aisle, strengthens body metabolism, decomposes many effects such as superabundant fats.Long-term edible konjak products, to Cancerous disease and constipation, diabetes, angiocardiopathies such as cancer of the esophagus, human primary gastrointestinal cancers, leukemia, lung cancer, brain tumors, obesity has good prevention effect, is a kind of ideal anticancer food and health slimming food.
The health food utilizing konjaku to make is more, disclosed in Chinese patent application " a kind of production method of konjak noodle " (201110382677.2), be process for major ingredient with flour, konjaku powder, edible vegetable oil and clear water, there is good health-care effect.Chinese patent application disclosed " a kind of rich selenium konjak (Moyu) rice and processing method thereof " (201110292320.5), be mixed by rich selenium konjaku 30-60%, rice meal 10-30%, mung bean flour 20-30%, described rich selenium konjaku is rich selenium konjaku flour or rich selenium konjaku glucomannan or the mixture of the two, its production method is: rich selenium konjaku, rice meal and mung bean flour are mixed, the stirring that adds water makes that mixed material is moisture reaches 40-45%, slivering is extruded in screw extruder, granulation, polishing, fluidized bed drying to safety moisture content 2%, packaging.Product not only have hypoglycemic, reducing blood lipid, antitumor, improve immunity, the effect such as clearing heat and detoxicating, and product does not have bad smell and the astringent taste of konjaku.But easily expand because its konjaku flour used is heated, when forming process, must transfer to produce high temperature due to screw extruder high-speed rotary, konjaku flour expands, bonds in ripe chemical process, be unfavorable for the shaping of konjak (Moyu) rice, therefore product appearance is bad, and mouthfeel is poor.
Summary of the invention
The object of the present invention is to provide a kind of konjak (Moyu) rice and production method thereof, it can effectively prevent konjaku composition from slaking process, excessive expansion occurring, and is conducive to formed product, and can improve outward appearance and the mouthfeel of konjak (Moyu) rice product.
For achieving the above object, embodiment of the present invention are: a kind of konjak (Moyu) rice, mixed by konjak tofu powder and rice meal, through poach, slaking, make grain of rice shape, oven dry forms, the weight proportion of described konjak tofu powder and rice meal is 1-30:100, and described konjak tofu powder is dry by konjak tofu, grinding is made.
As the technical scheme optimized, the weight proportion of described konjak tofu powder and rice meal is 15-18:100.
As the technical scheme optimized, described curing temperature is 80-85 DEG C.
The present invention also provides a kind of production method of konjak (Moyu) rice, comprises the following steps:
(1) konjak tofu powder and rice meal are pressed mixing, poach, places 30-40 minute under normal temperature, mixture water content 30-34%, the weight proportion of described konjak tofu powder and rice meal is 1-20:100, and described konjak tofu powder is dry by konjak tofu, grinding is made.
(2) extruded with screw extruder, make grain of rice shape, during extruding, extruding cavity temperature controls, at 80 ~ 85 DEG C, to be dried to water content and to be less than 5%, packaging.
As the technical scheme that aforementioned production method is optimized, after making grain of rice shape, then heating using microwave 5-8 minute, heating-up temperature 80-85 DEG C.
As the technical scheme that aforementioned production method is optimized, described konjak tofu powder is made up of the method comprising the following steps;
(1) in aluminum pot, add water, then add konjaku flour, mashing off, the weight proportion of described konjaku flour and water is 1:50 ~ 55.
(2) take the soda ash of konjaku flour weight 18-22%, by dissolved in boiled water, gently join in pot, equidirectional rapid stirring, buck and giantarum paste are fully mixed thoroughly, changes into after mixing thoroughly and stirring slowly, when giantarum paste surface has jellied bean curd shape thing to occur, stop immediately stirring;
(3) giantarum paste starting to condense is poured into rapidly in sizing dish, add a cover standing 5-6 minutes, condense into konjak tofu, stripping and slicing, add cold water cooling, cooled konjak tofu is placed in the aluminum pot big fire boiled water and boils sclerosis in 15-20 minutes;
(4) by ready-made konjak tofu block section, vacuum drying, pulverizes.
As the embodiment that above-mentioned preparation method is optimized, in step (1), described konjaku flour is for be purified to Glucomannan content more than 70% through edible alcohol, and a degree of granularity≤0.125mm accounts for the konjaku powder of more than 90%.
As the embodiment that above-mentioned preparation method is optimized, in step (1), the weight proportion of described konjaku flour and water is 1:52.
As the embodiment that above-mentioned preparation method is optimized, in step (2), described buck has added within half a minute, and filling point should at the middle part of aluminum pot radius.
As the embodiment that above-mentioned preparation method is optimized, in step (3), by the konjak tofu of stripping and slicing, add cold water cooling and soak 10-20 minute.
The present invention adopts and is produced by konjak tofu powder and rice meal, and because konjak tofu powder can not expand because being heated, the konjak (Moyu) rice outward appearance of producing is neatly shaping, glossy, and mouthfeel is better.Preparation method of the present invention, according to the physical and chemical performance feature of konjaku flour, adopts the semi-curing temperature of 80-85 DEG C, is conducive to formed product, and can prevent the conversion of active ingredient from losing.Konjak tofu powder in the present invention adopts the proportioning of rational konjaku flour, water and soda ash and special process to make, and effectively can alleviate the alkali taste of product, improve the mouthfeel of product.Product boiling water of the present invention soaks 8-10 minute i.e. edible, also can mix with rice boil edible.
