Problems solved by technology

However, the types of lotus seed products currently on the market are single, mostly dried and canned foods, and the research on lotus seed paste products is still in the blank, which greatly limits the development of lotus seed industry
However, unlike potatoes and yams, the study found that the solubility of lotus seed paste is poor due to the poor solubility of lotus seed paste.
In addition, commercially available mud products, such as mashed potatoes and yams, etc. need to be brewed in boiling water to dissolve them completely, and cold water cannot be soaked, which is extremely inconvenient

[0027] The preparation method of lotus seed puree provided by the present invention includes the following steps:

[0028] Step 1: The coarse white fungus powder that has passed through a 60-mesh screen is crushed by an airflow ultrafine pulverizer and then passed through a 400-600 mesh screen to obtain the ultra-fine white fungus powder, and the white fungus ultra-fine powder and distilled water are pressed at 1~3:5~ After stirring and mixing, the mass ratio of 15 is naturally swelled for 10-20 minutes, and then heated in a water bath for 10-20 minutes to obtain Tremella gel liquid;

[0029] Step 2: After blanching the nipple-shaped dark brown protrusions from the fresh lotus seeds for 2~3min, steam it at 90~120℃ for 20~40min, then add the color protector to beat, and then add citric acid to adjust to The pH of the slurry is 4.0-5.5 and continue to beat to obtain lotus seed slurry;

[0030] Step 3: Add cellulase to the lotus seed pulp in step 2 for enzymatic hydrolysis for 7-9 hour...

Abstract

The invention provides a lotus seed paste and a preparation method thereof. The preparation method comprises the steps of mixing tremella fuciformis ultrafine powder obtained by crushing of an air-flow ultrafine grinder with distilled water, naturally swelling and then heating in a water bath to obtain a tremella fuciformis gel solution; blanching a papillary dark brown prominence which is cut from a fresh lotus seed, then cooking the papillary dark brown prominence, adding a color retention agent for pulping, adding a citric acid to adjust the pH of the slurry to 4.0-5.5, continuing pulping,and then adding cellulose for enzymolysis; mixing the lotus seed slurry subjected to enzymolysis with distilled water, sequentially performing microwave heating treatment and colloid milling treatmentto obtain a lotus seed emulsion; sequentially adding milk powder, salad oil, white granulated sugar, edible salts, the tremella fuciformis gel solution, an emulsifying agent and a stabilizing agent to the lotus seed emulsion while stirring to obtain a mixture, and then spray-drying the mixture, wherein the addition amount of the tremella fuciformis gel solution is 10-30% by weight of the lotus seed emulsion. The lotus seed paste prepared by the invention can be brewed with cold water and is good in solubility.

Description

Technical field [0001] The invention relates to the technical field of food processing, in particular to a lotus seed puree and a preparation method thereof. Background technique [0002] The lotus seed is the seed of the lotus plant of the Nymphaeaceae family and is a traditional nourishing product. Lotus seeds not only contain protein, sugar water compounds, vitamins and a large amount of calcium, phosphorus, iron, zinc and other trace elements, but also contain a variety of alkaloids, hyperoside, superoxide dismutase, liensine and other biologically active ingredients, etc. Lotus seeds and their processing are highly valued by people. A variety of materials prove that lotus seeds not only have edible value, but also have medicinal effects, such as the dietary treatment of diabetes, lowering blood pressure, protecting liver and liver, anti-oxidation, anti-aging and anti-cancer effects. However, in the process of lotus seeds being used to develop prepared foods, it is often ne...
