Description

A kind of method of microbe fermentation method extraction walnut health-care grease
Technical field
The invention belongs to food processing fields, and in particular to a kind of side of microbe fermentation method extraction walnut health-care grease Method.
Background technology
Walnut oil is to use walnut kernel for raw material, vegetable oil made of squeezing.Belong to edible oil.The fat content of walnut Up to 65%-70%, shelter have first of woody oleiferous plants, there is the good reputation of " oil depot on tree ".It is carried and being selected the essence using modern crafts, this is just It is walnut new generation product -- walnut oil.Walnut oil is to choose good walnut to do raw material, and use technique system leading in the world The natural fruit oil juice taken out.In the international market, walnut oil is known as " east olive oil ", and consumption is equally received with olive oil Person favors.According to analysis, fatty main component is glyceryl linoleate, leukotrienes and olein, these are all human body institutes Required aliphatic acid.Walnut oil is that walnut kernel is made up of oil expression, refining, purification, and color and luster is yellow or brown color, is people Ideal advanced edible cooking oil in daily life.
The preparation method of walnut oil mainly has carbon dioxide supercritical extraction, solution to leach extraction, water substitution, water phase at present Enzymatic isolation method and squeezing method.Oil yield quality obtained by carbon dioxide supercritical extraction is good at present, but operating pressure is big, when extraction Between it is long, and to equipment requirement height, investment is high, and oil product is expensive, and popularization is not easy.Solution leaches extraction, and there are intrinsic inflammable and explosive of solvent Danger, while chemical solvent remain, influence oil product.Oil quality that water substitution and aqueous enzymatic extraction obtain is high, and crude oil without It need to refine to obtain the final product, oil yield is high, but Cortex walnut seriously affects the taste and color of walnut oil without removing.Squeezing method is for I The most common mode of state, oil yield is high, environmentally protective, but the Residual oil contained in the oil cake in squeezing method is high, and labor intensity is big, It is of high cost.And cold-press, due to being carried out at a temperature of less than 60 DEG C, stability and oil product are all very high, but oil yield It is low, and the process time is long, influences oil product popularization.
South China Science & Engineering University Zhao scheme penetrating judgment, which is awarded, discloses an a kind of patent " method of high efficiency extraction walnut oil " patent No.: The CN201510567265.4 patented methods are the substances such as protein and cellulose in degrading walnut kernel using biological enzyme formulation, So that grease is fully discharged, it is strong that the fat globule interfacial film that nonionic surfactant makes walnut digest in emulsion is then added Degree reduces, high to reach in conjunction with centrifugal separation technology further such that the fat globule in walnut enzymolysis emulsion ruptures The purpose of effect extraction walnut oil.Make the degradations such as albumen and the cellulose in walnut kernel by mode of action, but this method is most Enzyme deactivation is needed eventually, easily causes Oxidation of Fat and Oils, influences the flavor taste of walnut lubricant.
Invention content
It is an object of the invention to could grease be oxidizable rotten present in traditional enzymatic isolation method extraction walnut lubricant asks Topic provides a kind of method of microbe fermentation method extraction walnut health-care grease, walnut kernel is decomposed by the method for microbial fermentation In protein, the ingredients such as carbohydrate and cellulose, then Extraction and enrichment healthy oils are passed through using the broken emulsification of cell crushing instrument It crosses centrifugal filtration and obtains walnut health-care grease crude oil, then obtain walnut health-care grease by refining.
The purpose of the present invention and its technical problem underlying is solved using following technical scheme to realize:A kind of microorganism The method that fermentation method extracts walnut health-care grease, it is characterised in that include the following steps:
A. the pretreatment of walnut kernel:Walnut peeling is obtained into walnut kernel, by weight 1 portion of walnut kernel, 3-5 parts of pure water are added, It is beaten using high speed beater, is uniformly mixed so as to obtain walnut kernel slurry;
B. walnut kernel adds koji fermentation:Walnut kernel slurry is heated to 25-30 DEG C, is fitted into ceramic wine jar, it is logical that efficient distiller's yeast is added Aerobe fermentation, fermentation temperature are 25-30 DEG C, and the additive amount of efficient distiller's yeast is the 0.3-0.5% of walnut kernel slurry weight, fermentation time It is 5-10 days, obtains the oil mixing with water zymotic fluid rich in walnut health-care grease after fermentation;
C. it is crushed emulsification:The oil mixing with water zymotic fluid that will be enriched in walnut health-care grease, is added in ultrasonic cell disruption instrument, stirs It mixes 10-20 minutes broken, obtains oil mixing with water emulsion;
D. filter centrifugation:Oil mixing with water emulsion will be taken out in ultrasonic cell disruption instrument after gauze filtering to exist using centrifuge Rotating speed is to centrifuge 5-15min under 5000-8000r/min, and supernatant liquor is taken to obtain walnut health-care grease crude oil;
E. crude oil refines:Obtained walnut health-care grease crude oil is passed through into depickling, is dewaxed, decoloration obtains after vacuum deodorization processing Walnut health-care grease;
F. it examines filling:Walnut health-care grease by refining is filling after the assay was approved to obtain finished product grease.
The microbe species in efficient distiller's yeast wherein described in step B contain yeast, fungi, mould, and bacterium is therein Two or more mixing;Ultrasonic cell disruption instrument operating condition is set as in step C:30-40 DEG C of temperature, ultrasonic power are 800-1000W。
The present invention has clear advantage and advantageous effect compared with prior art.From above technical scheme:
(1)The present invention sends out Extraction and enrichment walnut health-care grease using microbial fermentation, in extraction process temperature control 30 DEG C with Under, it avoids Oxidation of Fat and Oils caused by high temperature and goes bad, influence flavor taste;
(2)Sonicator is used in the method for the present invention, is on the one hand the emulsification of walnut lubricant fat globule, grease extracts, On the other hand by the bacteria inactivation rate in zymotic fluid, reduce high-temperature sterilization link, ensure that the quality of grease;
(3)It is acted on by microbial fermentation in the method for the present invention, is amino acid by protein degradation in walnut kernel, makes walnut lubricant In be rich in amino acid, increase the health-care efficacy of walnut lubricant.
