Specific embodiment
The preparation method of walnut oil of the invention, comprising the following steps:
(1) walnut kernel is crushed and is dried, drying temperature is 40~50 DEG C, and drying time is 30~60 minutes；
(2) walnut meat powder after drying is worn into slurry；
(3) parts by weights meter takes 100 parts of slurries, into slurry be added 8~12 parts of sodium carbonate, 4~8 parts of cellulases,
0.5~1 part of α-determines powder enzyme, 3~6 parts of protease and 400~600 parts of distilled water, stirs and evenly mixs；Sodium carbonate, cellulase, α-are fixed
Powder enzyme and protease make the clasmatosis in slurry, intracellular nutritional substance release, between protein-water, protein-protein
Interaction enhanced, enhancing stirs oily effect, improves oil yield, wherein the vigor of cellulase be >=10000 unit of activity/
g；The vigor that α-determines powder enzyme is >=4000 unit of activity/g；The vigor of protease is >=100000 unit of activity/g；Whipping temp
It is 25~35 DEG C, pH is 6.5~6.8, and speed of agitator is 4000~5000r/min, and mixing time is 3~5 hours；Whipping temp
Higher, the albumen solubility of walnut increases as the temperature rises, the stereochemical structure stretching, extension of molecule, to the adsorption capacity of oil droplet
Increasing, oil yield is lower, and when temperature is higher than 65 DEG C, the protein denaturation of walnut, the intermolecular precipitating that be combined with each other, to oil droplet
Adsorption capacity rapid drawdown, so oil yield sharply increases, but oil quality declines, and therefore, selecting whipping temp is 25~35 DEG C,
Mild condition, protein denaturation is few, does not destroy nutritional ingredient, and utilization rate is high；Mixing time is longer, and oil yield is higher, and when friendship
Class's time is more than 5 hours, and oil yield increasing degree is slow, in order to save the production cycle, reduces energy consumption, while also slurry being avoided to put
Therefore setting overlong time influence quality selects mixing time for 3~5 hours；
(4) ultrasonic mixing 60~90 minutes under 50~60 DEG C, 30~35kHz, it is primary at interval of 5 minutes ultrasounds, instead
Answer ultrasound 2~3 times to obtain enzymolysis product；The synergistic effect of the ultrasonic effects such as sharp pounding, cavitation and stirring using ultrasonic wave, mentions
The molecular motion frequency and speed of high slurry make cell tissue generate cavitation bubble collapse, further make cell rupture, improve fuel-displaced
The colleague of rate shortens extraction time, guarantees walnut oil quality；
(5) enzymolysis product is centrifuged 30~60 minutes under 20~25 DEG C, the revolving speed of 8000~12000r/min, takes upper layer
It is centrifuged product, obtains walnut oil.With the increase of centrifugal rotational speed, oil yield can be improved, at 20~25 DEG C, mild condition will not
Destroy the nutritional ingredient in walnut oil.
