Embodiment 1

[0024] The invention provides a kind of process for extracting starch from spinach, the specific operation steps are:

[0025] Step 1: Harvest the scorpions and further select them, expose them to the sun for drying, place the dehydrated scorpions on the primary filter screen, knead the dehydrated scorpions repeatedly to make them separate into particles, and sieve them out For straw and large particles of impurities, place the sun-dried sieves on the secondary filter screen to sieve, so that the small particles of impurities fall down and leave the stalks on the secondary filter sieve. The aperture of the primary filter screen is smaller than the sieves. The pore size of the secondary filter screen is larger than the particle size of the scorpions. The two-stage filter sieve filters the small particles of impurities and the large particles of impurities respectively, and at the same time separates the scorpions. Separation of seeds and impurities to obtain high-quality raw ma...

Abstract

The invention discloses an extraction process and an application and manufacturing method of finger millet starch. The extraction process comprises the following steps: harvesting finger millet, further carefully selecting, drying in the sun, placing dehydrated finger millet on a first-stage filter screen, repeatedly rubbing the dehydrated finger millet to enable the dehydrated finger millet to bein a grain separation state, screening out straws and large-particle impurities, and placing and screening the aired finger millet on a second-stage filter screen. The high-quality finger millet rawmaterial is obtained through two-stage filtering, screening and winnowing, deflated material inferior-quality products are removed again by a water flotation method, finger millet endosperm is separated from finger millet seed coat by alternating multiple times of thermal expansion and cold contraction, endosperm of the expanded finger millet is soaked, water is added, grinding is performed into apulp, the pulp is filtered by using a filter cloth to obtain a filtrate, the filtrate is diluted, and then is washed for multiple times to obtain a precipitate, and starch microcrystals are separatedout and dried to obtain the high-quality finger millet starch. The process is simple, convenient to promote and use, low in impurity content and capable of effectively utilizing resources, and the effective extraction rate and purity of the starch can be guaranteed to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of starch processing and production, in particular to a process for extracting starch from spinach and its application and manufacturing method. Background technique [0002] It is a kind of grass in the genus Poaceae, and its aliases include Longzhu millet, chicken claw millet, African broomcorn millet, and duck-foot millet. It is a kind of miscellaneous grains, which has been cultivated for thousands of years. It is widely planted in the African continent, India, and Nepal. It is also cultivated in a small amount in the southwestern provinces of Tibet, Guangdong, Guangxi, and Hainan. Its protein content reaches 8%, and the millet seed protein is a high-quality protein, the content is equivalent to that of rice; the fat content is equivalent to that of wheat; it is rich in natural organic minerals, and the contents of calcium, potassium, magnesium, selenium, and zinc are 16.4% of that of rice. , 4.7, 4.7, ...
