Problems solved by technology

This type of product contains high concentration of alcohol, which is extremely inconvenient to take. Many products have a strong pungent taste, which is difficult for consumers to drink. Some consumers are allergic to alcohol and cannot take propolis products containing alcohol, which limits the further application of propolis.

Embodiment 1

[0030] A preparation method of propolis purple sweet potato powder, comprising the following steps:

[0031] Step 1: Clean and peel the fresh purple sweet potato, cut it into 0.5cm square blocks, add 2 times the weight of water after blanching, crush it with a tissue masher for 30 seconds to obtain purple sweet potato pulp, and use amylase 60 for the purple sweet potato pulp ℃ enzymatic hydrolysis for 30 minutes, the enzyme dosage is 1000mg / L, then adjust the pH value to 4 with citric acid, and then use cellulase and glucoamylase to enzymatically hydrolyze at 60 ℃ for 30 minutes. 1000mg / L, centrifuged and filtered to obtain purple sweet potato juice, stored in a refrigerator at 4°C for later use;

[0032] Step 2: freeze the propolis at -80°C for 2 hours, crush it and pass it through a 40-mesh sieve, and bottle it for later use;

[0033] Step 3: Take 5g of propolis that has been frozen and pulverized, grind it into a paste with 25mL of ethanol solution with a volume concentrat...

Abstract

The invention relates to a preparation method of propolis purple sweet potato powder, and belongs to the technical field of preparation of propolis powder. The preparation method comprises the following steps of preparing purple sweet potato juice, freezing and cooling the propolis, performing grinding with a ceramic grinding bowl, performing crude extraction, performing normal-temperature superhigh pressure extraction, mixing the purple sweet potato juice with propolis extracting liquid to obtain mixed liquid, performing concentration, performing freeze drying to obtain propolis coarse powderand performing crushing to obtain propolis micro powder. According to the propolis purple sweet potato powder, the sensory quality of the propolis products is improved, and a way is provided for further widening of the application field of the propolis products. Purple sweet potatoes can well improve poor mouth feel of the propolis, and the propolis purple sweet potato powder has obvious purple sweet potato fragrance and is free from any poor pungent taste. Crude extraction is performed firstly with ethanol, and then superhigh pressure extraction is performed, so that the utilization rate andpowder yield of the propolis can be increased; and the superhigh pressure extraction is adopted, so that the problems that microwave extraction causes non-uniform heating and the ultrasonic extraction is high in power consumption and high in noise, are solved. The propolis micro powder is small in granule size, the average particle diameter is smaller than 70[mu]m, and the propolis purple sweet potato powder is regular in shape, good in uniformity and smooth in surfaces.

Description

technical field [0001] The invention belongs to the technical field of propolis powder preparation, and in particular relates to a preparation method of propolis purple sweet potato powder. Background technique [0002] Propolis is a resin that bees collect from tree buds, bark and other parts of plants, and then mixed with glandular secretions such as tongue glands and wax glands of bees, and processed and transformed by bees into a gelatinous substance. In recent years, studies have found that propolis has various biological functions such as anti-cancer, anti-pathogenic microorganisms, protection of the liver, improvement of the body's immune function, and anti-oxidation, so it has attracted widespread attention from merchants all over the world. my country has listed propolis as a material list that can be added to health food, which provides a policy guarantee for the development and utilization of propolis. [0003] The functional components in propolis are often extr...
