The invention discloses a production method of
cyperus esculentus oil and
cyperus esculentus flour. Water-soluble characteristics of water-soluble components of
cyperus esculentus and properties that
starch can form
starch milk dispersing in water,
protein is soluble in water under alkaline conditions and can be enzymed and the cyperus esculentus oil exists in cells and can break through walls to be released are utilized, the cyperus esculentus is smashed and soaked with water prior to being ground into thick liquid,
protein,
pectin and
cellulose are sequentially enzymed to break through the walls to release the oil, an oil-water mixture is obtained after
mixed materials are separated through pulp residues, and the oil-water mixture is subjected to oil-water separation to obtain cyperus esculentus
crude oil and cyperus esculentus extract; the cyperus esculentus
crude oil is dried and filtered to obtain the cyperus esculentus oil; the cyperus esculentus extract is subjected to heating and gelatinizing into
starch, homogenizing, concentrating and
spray drying to obtain the cyperus esculentus flour. The method is easy to implement, convenient in operation, low in cost, free from organic solvents, free from refining of oil, high in
utilization rate of raw materials, sufficient in extraction of active ingredients and
nutrient substances, good in
solubility property, remarkable in healthcare function, good in taste and mechanized.
