preparation example Construction

[0018] The preparation method of selenium-enriched sweet potato vermicelli and the selenium-enriched red sweet potato vermicelli provided in the embodiments of the present invention can be applied to the process of preparing selenium-enriched red sweet potato vermicelli. Specifically, it can be applied in the process of preparing selenium-enriched sweet potato vermicelli by using concentrated selenium-enriched water.

[0019] A kind of preparation method of selenium-enriched sweet potato vermicelli that the embodiment of the present invention provides can comprise the following steps:

[0020] (1) Preparation of sweet potato starch

[0021] Wash and pulverize sweet potatoes, pass through a 100-mesh sieve first, and then pass through a 200-mesh sieve to obtain coarse sweet potato starch milk. The obtained coarse sweet potato starch milk is sent to a DPF445 disc separator to remove yellow powder to obtain sweet potato starch milk. The obtained sweet potato starch milk is dried ...

Embodiment approach 1

[0064] Specifically follow the steps in the following example:

[0065] (1) Preparation of sweet potato starch

[0066] Wash and crush the sweet potatoes, pass through a 120-mesh sieve first, and then pass through a 300-mesh sieve to obtain coarse sweet potato starch milk. The obtained coarse sweet potato starch milk is sent to a DPF445 disc separator to remove yellow powder to obtain sweet potato starch milk. The obtained sweet potato starch milk is dried. That is, sweet potato starch, set aside;

[0067] (2) Preparation of pea starch

[0068] After cleaning the peas, soak them in the water medium for 70 hours, remove the soaked peas, drain the water, grind them, separate them through a 120-mesh sieve to remove the coarse residue, and pass the pea slurry after removing the coarse residue through a 300-mesh The pea starch slurry is sieved, and the obtained pea starch slurry is dried to obtain the pea starch, which is set aside;

[0069] (3) Pueraria powder pretreatment

Abstract

Embodiments of the invention disclose a preparation method of selenium-rich sweet potato vermicelli and the selenium-rich sweet potato vermicelli, relates to the technical field of healthcare foods, and solves the problems of single taste and relatively single nutritional ingredient. The method comprises the steps of uniformly mixing 69-97.5 parts of sweet potato starch, 1.5-30 parts of pea starchand 10-25 parts of kudzuvine root powder in a container to obtain mixed starch, adding water heavier than the mixed starch by 1-3 times into the container, performing full beating to obtain uniform and exquisite homogenate, adding acidic slurry into the homogenate, performing uniform stirring, performing standing at the normal temperature for 2-6 hours to form layers which are an upper layer being clear liquid I, a middle layer being yellow slurry and a lower layer being precipitated starch, taking out the clear liquid I of the upper layer to be mixed with the acidic slurry for the next starch acidic slurry pretreatment step for reuse, and taking out and discarding the yellow slurry of the middle layer. The method is applied to the process of preparing the selenium-rich sweet potato vermicelli from concentrated selenium-rich water.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of health food, in particular to a preparation method of selenium-enriched sweet potato vermicelli and selenium-enriched red sweet potato vermicelli. Background technique [0002] Vermicelli is a traditional food. The earliest record of vermicelli comes from the "Qi Min Yao Shu" written by the Northern Wei Dynasty, which has a history of at least 1,400 years in my country. Vermicelli is a kind of starch product made by using the principle that amylose with a large degree of polymerization is easy to age after gelatinization to form a thermally irreversible gel with good elasticity and toughness. [0003] The raw materials for traditional vermicelli processing include bean starch such as mung bean, broad bean, and pea. Bean starch contains a high proportion of amylose with a high degree of polymerization, and can be directly processed into vermicelli with fine taste, good elasticity ...
