Embodiment 1

[0046] Such as figure 1 As shown, the method of extracting kidney bean starch and co-producing kidney bean protein powder and dietary fiber powder is as follows,

[0047] Weigh 100Kg of red kidney beans after selection and removal of impurities, soak in 300L sodium bisulfite solution with a concentration of 0.2% at 20°C for 24 hours, remove and place in 300L of clean water, stir and wash thoroughly for 10 minutes, remove Drain. Then add the washed kidney beans into 400L of clear water, soak at room temperature for 20 minutes, and use a built-in screen with the function of self-separation of pulp and residue to refine pulp with a 100-mesh refiner to obtain a primary slurry. Add the residue to 400L of clear water for secondary refining, separate the slurry to obtain secondary slurry and wet residue, combine the primary and secondary slurry to obtain a mixed slurry, and pass through a 200-mesh sieve to obtain the undersize fine slurry for use in Kidney bean starch and kidney be...

Embodiment 2

[0052] The method of extracting kidney bean starch and co-producing kidney bean protein powder and dietary fiber powder is as follows,

[0053] Weigh 100Kg of white kidney beans after selection and removal of impurities, soak in 300L sodium bisulfite solution with a concentration of 0.1% at 45°C for 12 hours, remove and place in 300L of clean water, stir and wash thoroughly for 10 minutes, remove Drain. Then add the washed kidney beans into 400L of clear water, soak at room temperature for 20 minutes, and use a built-in screen with the function of self-separation of pulp and residue to refine pulp with a 100-mesh refiner to obtain a primary slurry. Add the residue to 400L of clear water for secondary refining, separate the slurry to obtain secondary slurry and wet residue, combine the primary and secondary slurry to obtain a mixed slurry, and pass through a 200-mesh sieve to obtain the undersize fine slurry for use in Kidney bean starch and kidney bean protein extraction; the...

Embodiment 3

[0058] The method of extracting kidney bean starch and co-producing kidney bean protein powder and dietary fiber powder is as follows,

[0059] Weigh 100Kg of black kidney beans after selection and removal of impurities, soak in 300L sodium bisulfite solution with a concentration of 0.15% at 35°C for 16 hours, remove and place in 300L of clean water, stir and wash thoroughly for 10 minutes, remove Drain. Then add the washed kidney beans into 400L of clear water, soak at room temperature for 20 minutes, and use a built-in screen with the function of self-separation of pulp and residue to refine pulp with a 100-mesh refiner to obtain a primary slurry. Add the residue to 400L of clear water for secondary refining, separate the slurry to obtain secondary slurry and wet residue, combine the primary and secondary slurry to obtain a mixed slurry, and pass through a 200-mesh sieve to obtain the undersize fine slurry for use in Kidney bean starch and kidney bean protein extraction; th...

Abstract

The invention relates to a method for extracting kidney bean starch and coproducing kidney bean protein powder and dietary fiber powder. The method comprises the following steps of: firstly, preprocessing kidney bean raw material, grinding into slurry and filtering to obtain filtrate, filter residue on a sieve and residues; secondly, adjusting concentration of the filtrate below the sieve, and carrying out hydrocyclone separation to obtain protein slurry at the upper layer and coarse starch slurry at the lower layer, and washing, dehydrating, drying, smashing and sieving the coarse starch slurry to obtain kidney bean starch; thirdly, carrying out ultrafiltration, ultrasonic treatment and drying on the protein slurry at the upper layer to obtain protein powder; fourthly, adding clear water into filter residue on the sieve and residue, carrying out enzymolysis after ultrasonic treatment, and carrying out filter pressing to obtain filtrate and filter residue; adding clear water into the filter residue, carrying out ultrasonic treatment, cooking, centrifugally separating to obtain supernate and sediment; washing, drying, smashing and sieving the sediment to obtain water-insoluble dietary fiber powder; and mixing the supernate with the filtrate, and carrying out vacuum concentration and drying to obtain water-soluble dietary fiber powder. The method provided by the invention is long in industrial chain, generates no three-waste pollution, and creates outstanding economic benefit.

Description

1. Technical field [0001] The invention relates to the field of deep processing of agricultural products, in particular to a method for extracting kidney bean starch and co-producing kidney bean protein powder and dietary fiber powder. 2. Background technology [0002] Kidney beans are one of the edible legume crops that are second only to soybeans in the world's cultivated area. China is the main producer and exporter of kidney beans, with an annual output of more than 800,000 tons and an annual export volume of 600,000 tons. [0003] Kidney beans contain 25-30% starch, 15-20% crude fiber, 20-25% protein, 1-1.5% fat, calcium 50-100mg / 100g, potassium 1500-1800mg / 100g, magnesium 150-200mg / 100g, sodium 0.5 -1mg / 100g, vitamins 2-5mg / 100g and trace functional factors such as saponins, isoflavones, urease, oligosaccharides, coumarin, alkaloids and various globulins, etc. It is a typical high-protein, low-fat , high potassium, high magnesium, low sodium, a complete range of amin...
