Description

A kind of okra fermented wine and brew method thereof
Technical field
The present invention relates to method of making liquor, specifically, relate to a kind of okra fermented wine and brew method thereof.
Background technology
Okra ( hibiscus esculentus), the annual herb plant.Okra is mainly edible with tender fruit, and the effect of stomach invigorating reason intestines is arranged, and is a kind of nutritive health-care vegetable.Flower, seed and root all can be used as medicine in addition.The tender pulp matter of okra is tender, lubricated, can be used for stir-frying and eating, cooking, cold and dressed with sauce.Except tender fruit is edible, its blade, bud, flower be edible also.The seed of okra contains the elements such as more potassium, calcium, iron, zinc, manganese.Okra nutritious, contain a large amount of stick-slip juice in young fruit, have special fragrance.Be mixed with pectin in its juice, cow's milk glycan and my glycan etc.Its pectin is soluble fiber, in the modern health new concept, very payes attention to.Often eating it has the stomach invigorating intestines, the effect of nourishing negative and positive.Contain according to surveying and determination protein 2.5 grams, fatty 0.1 gram, carbohydrate 2.7 grams, Mierocrystalline cellulose A 660 international unit in the tender fruit of every hectogram.Vitamins B 10.2 milligram, vitamins B 20.06 milligram, 44 milligrams of vitamins Cs, 81 milligrams of calcium, 63 milligrams, phosphorus, 0.8 milligram of iron are high-grade green nourishing health-care vegetables.It is food that okra mainly be take the tender fruit pod of children, when tender pod grows to the 8-10 cm long, is Harvesting Date, and the evening of gathering, the fruit pod was aging, and fiber is many, and poor quality loses vegetables and is worth.
At present, the processing and utilization of okra also rests on the primary stage, strengthens okra function and health care value research, and exploitation okra health foodstuff series, have important practical significance.Wherein, it is prepared into to wine and is not only one of effective means of problems such as solving short, fresh-keeping difficulty of okra ripening stage, tender fruit fiber, and can obtain nourishing function health promoting wine preferably.Because okra slurries viscosity is high, be unfavorable for fermentation, the production of okra wine, be to take the okra fruit as main raw material at present, is aided with the explained hereafter such as soaking in Chinese liquor, filtration, clarification, and the wine degree is high, and the production cycle is long, and in wine, nutritive ingredient is low.
Summary of the invention
For above shortcomings in prior art, the object of the invention is to provide a kind of fermented wine and method thereof prepared as raw material by the tender fruit of okra and okra flower of take.The method production cost is low, and transformation efficiency is high, and the okra wine that adopts the method to make is nutritious, unique flavor, mouthfeel are soft, good health care effect.
