Abstract

The invention discloses an ultrasonic-based method for increasing the yield and quality of black soybean sprouts. The method sequentially includes the steps of firstly, weighing appropriate weight of black soybean without insects and mildew, and washing 3-5 times with tap water; secondly, soaking the washed black soybean in warm water at about 25 DEG C, keeping the temperature for 6-9 hours, and removing damaged black soybean; thirdly, wrapping the soaked black soybean with gauze, placing into an ultrasonic generator (220v/50Hz, 500W), and adding an appropriate amount of water to allow the black soybean to be just immersed by the water; fourthly, processing with ultrasonic for 20-30 minutes, and inserting a thermometer into the water to monitor water temperature so as to allow the water temperature not to exceed 30 DEG C; fifthly, raising the black soybean sprouts with a conventional method. By the method, the yield and quality index of the black soybean sprouts can be increased evidently.

Description

A kind of method improving Black bean sprout seedling Yield and qualities based on ultrasonic

Technical field

The present invention relates to a kind of method improving beans shoot vegetable Yield and qualities, particularly a kind of method adopting ultrasonic process to improve Black bean sprout seedling Yield and qualities.

Background technology

Black soya bean has medicinal and edibility concurrently, can reduce cholesterol, kidney tonifying, beneficial spleen, expelling phlegm and arresting coughing, toxin expelling, fat-reducing and improve the multiple efficacies such as anaemia; Its shoot vegetable mouthfeel is fresh and tender, nutritious, containing rich in protein, carbohydrate, and be rich in iron, calcium, phosphorus, carotin and multivitamin, therefore nutritive value is better than the shoot vegetable of soya bean and mung bean, therefore enjoys great popularity.But in order to improve the output of shoot vegetable, have illegal retailer to add the additive of non-food stuff in bean sprouts, the long-term edible bean sprouts containing this additive can cause serious consequence, is called as " ordeal bean bud ".Therefore, how to accomplish the Yield and qualities that can improve bean sprouts, again can safety non-pollution, be practical problem urgently to be resolved hurrily.Ultrasonic to plant favorable influence approve by modern science, large quantity research shows, the biomass of plant seedlings after ultrasonic process, as fresh weight, dry weight obviously increase.Moreover, through the seed of ultrasonic process, the index of quality such as seedling soluble sugar, soluble protein and Determination of Vitamin C after its sprouting also significantly increase.But can ultrasonic process improve the Yield and qualities of Black bean sprout seedling, has not yet to see report.

Summary of the invention

Patent object of the present invention finds a kind of safe and harmless method newly to improve Black bean sprout seedling Yield and qualities, increases the nutritive value of Black bean sprout seedling.

Patent of the present invention is achieved through the following technical solutions: first take approrpiate wts without worm without mould black soya bean seed, with tap water 3 ~ 5 times.

Be immersed in the warm water of about 25 DEG C by the black soya bean seed rinsed well, constant temperature keeps 6 ~ 9 hours, then rejects damaged seed.

Bound up with gauze by black soya bean seed after soaking, put into supersonic generator (220v/50Hz, 500W), add appropriate water, the water yield is advisable with just submergence seed.

Open supersonic generator, carry out ultrasonic process 20 ~ 30 minutes, in water, insert a thermometer monitors water temperature, can not more than 30 DEG C.

Conventional method is adopted to raise bean sprouts.

Adopt the effect of above-mentioned design: by the enforcement of above scheme, output and the index of quality of Black bean sprout seedling can be significantly improved.

Embodiment

In following embodiment, method therefor is conventional method if no special instructions.

Embodiment one: take the black soya bean seed that two parts of 2000g quality are intact, rinse 3 times with water; Then seed to be immersed in the warm water of 25 DEG C 6 hours, after immersion, to choose damaged seed.By seed one piece of clean binding up with gauze, be placed in supersonic generator, and add appropriate water, process 20 minutes, maintain water temperature in this process at 25 ~ 28 DEG C.Adopt conventional method to raise bean sprouts after process, control water, gentle light, after about 1 week, Black bean sprout seedling can be gathered in the crops.Yield and qualities index determining is as follows: (1) determination of yield: directly weigh on electronic balance after being filtered dry bean sprouts surface moisture, high by 7.2% than without ultrasonic process of the output of the Black bean sprout seedling of ultrasonic process.(2) index of quality measures: often organize and get three parts of materials, conventionally measure soluble sugar and the soluble protein content of shoot vegetable, its ultrasonic processed group is higher than undressed difference by 19.8% and 8.4%.

Embodiment two: take the black soya bean seed that two parts of 2500g quality are intact, rinse 3 times with water; Then seed to be immersed in the warm water of 26 DEG C 7.5 hours, after immersion, to choose damaged seed.By seed one piece of clean binding up with gauze, be placed in supersonic generator, and add appropriate water, process 30 minutes, maintain water temperature in this process at 25 ~ 28 DEG C.Adopt conventional method to raise bean sprouts after process, control water, gentle light, after about 1 week, Black bean sprout seedling can be gathered in the crops.Yield and qualities index determining is as follows: (1) determination of yield: directly weigh on electronic balance after being filtered dry bean sprouts surface moisture, high by 6.8% than without ultrasonic process of the output of the Black bean sprout seedling of ultrasonic process.(2) index of quality measures: often organize and get three parts of materials, conventionally measure soluble sugar and the soluble protein content of shoot vegetable, its ultrasonic processed group is higher than undressed difference by 15.2% and 9.6%.

Embodiment three: take the black soya bean seed that two parts of 3000g quality are intact, rinse 3 times with water; Then seed to be immersed in the warm water of 26 DEG C 9 hours, after immersion, to choose damaged seed.By seed one piece of clean binding up with gauze, be placed in supersonic generator, and add appropriate water, process 25 minutes, maintain water temperature in this process at 26 ~ 28 DEG C.Adopt conventional method to raise bean sprouts after process, control water, gentle light, after about 1 week, Black bean sprout seedling can be gathered in the crops.Yield and qualities index determining is as follows: (1) determination of yield: directly weigh on electronic balance after being filtered dry bean sprouts surface moisture, high by 7.1% than without ultrasonic process of the output of the Black bean sprout seedling of ultrasonic process.(2) index of quality measures: often organize and get three parts of materials, conventionally measure soluble sugar and the soluble protein content of shoot vegetable, its ultrasonic processed group is higher than undressed difference by 17.6% and 7.9%.

Implementation result: through the Black bean sprout seedling of such scheme process, its yield and quality, all higher than undressed shoot vegetable, improves the nutritive value of Black bean sprout seedling, has good economic and social benefit.
