Embodiment Construction

[0022] 1) Process flow

[0023] Acceptance of lotus seeds→crushing→salt extraction, acid precipitation, centrifugation→stirring, centrifugation→ultrafiltration→drying→packaging

[0024] 2) Operation points

[0025] ① Acceptance of lotus seeds: Picking seven to eight mature fresh lotus, there should be no deterioration and no peculiar smell; special attention should be paid to excessive pesticide residues in lotus due to improper use of pesticides or insufficient safety interval after pesticide application;

[0026] ② Pulverization: The dried lotus seeds are pulverized with a pulverizer to make them into lotus seed powder.

[0027] ③Salt extraction and acid precipitation centrifugation: the pH value of the NaCl solution is about 6.4, and the pH value of the extracted mixed solution is adjusted with HCl and NaOH, and the pH value is adjusted to 4.2.

[0028] ④ Stirring and centrifugation: Centrifuge the mixed lotus seed protein solution with a centrifuge and collect the supern...

Abstract

The invention provides lotus seed protein powder and a production method thereof. The production method comprises the following steps: 1. carrying out acceptance inspection on lotus seeds: picking fresh lotus seeds with shells, wherein 70%-80% of parts of the picked lotus seeds are matured; 2. crushing; 3. carrying out salt extraction, acid deposition and centrifugation: regulating the pH value of the extracted mixture to be 4.2 by using hydrochloric acid and sodium hydroxide; 4. performing stirring and centrifugal filtration; 5. carrying out ultrafiltration: carrying out ultrafiltration concentration on filtrate to obtain high-concentration protein; 6. drying the protein by a spray dryer to obtain finished protein powder product; and 7. packaging under a vacuum condition. Compared with the prior art, the lotus seed protein powder and the production method of the lotus seed protein powder have the beneficial effects that firstly, the lotus seed protein powder fully keeps the fresh scent, the color is changed from white to pale yellow, the lotus seed protein powder can be prepared into even paste by hot water and has fine and smooth mouthfeel; secondly, the production process of the lotus seed protein powder is simple and facilitates scale production, package, transportation and sale; thirdly, the lotus seed protein powder is convenient to store, and has shelf life up to 12 months at normal temperature.

Description

(1) Technical field [0001] The invention relates to lotus seed protein powder and a production method thereof. (2) Technical background [0002] Lotus seeds have high nutritional value and are rich in protein, fat, carbohydrates, calcium, phosphorus and potassium. In addition to the ingredients that can form bones and teeth, they can also promote blood coagulation, activate certain enzymes, maintain nerve conduction, and calm the nerves. Nerves, maintain the stretching of muscles and the rhythm of heartbeat. Lotus seeds have the effect of nourishing the mind and calming the nerves. Middle-aged and elderly people, especially mental workers, often eat them. They can strengthen the brain, enhance memory, improve work efficiency and prevent the occurrence of senile dementia. The lotus seed heart tastes extremely bitter, but it has a significant cardiotonic effect, can expand peripheral blood vessels, and lower blood pressure. The lotus heart also has a good effect of removing ...
