Description
Technical field
The present invention relates to a kind of processing methods of sesame oil, belong to field of agricultural products processing.
Background technique
Sesame is one of the main oil plant in China, sesame other than grease rich in and protein, also contain there are many
Nutritional ingredient, these nutritional ingredient A wide selection of colours and designs, rich content can not only meet human nutrition demand, and can be preferable
Ground is absorbed by human body.Sesame oil is the oil extracted from sesame seed, rich in fatty acid needed by human -- linoleic acid and oil
Acid (respectively contains 40wt%-45wt%), is a kind of very high vegetable oil of nutritive value, while also having good medical value.Sesame
The traditional extraction process of oil mainly has high temperature squeezing method, extraction method and water substitution etc..High temperature squeezing method, sesame are fried through high temperature
It makes (general 200 DEG C or more), will lead to the destruction of protein serious degenerative and thermally labile component and the loss of volatile matter, and
Easily cause carcinogen BaP severe overweight.That there are equipment is more for extraction method, invests big, at high cost, solvent residual amount
The problems such as exceeded.Ground sesameseed oil made from water substitution is a kind of advanced flavored oils of aromatic flavour, usually roasts sesame high temperature
Afterwards, defibrination mentions oil.Water substitution processing is equally also required to carrying out sesame into high temperature pretreatment, such as fries seed temperature 170~200
DEG C, 60~70 DEG C of defibrination temperature.Water substitution preparing benne oil is during defibrination, due to passing through violent immixture, sesame
Jute pulp is easy to happen emulsion, causes subsequent water-oil separating difficult, and since protein denaturation is serious, by-product is difficult to benefit
With.Low temperature liquefaction is conducive to retain the heat-sensitive substances such as phenols in grease, is the developing direction that grease is produced.Although now
Cold-press to be developed to produce for sesame oil, entire expressing process can retain more heat-sensitive ingredients without high temperature, but
This technology be not at present it is overripened (mainly squeeze when sesame repeatedly extruded in press chamber, press chamber heats up excessively high
Problem is difficult to be resolved), and cold-press oil yield is relatively low.As the Chinese patent of Authorization Notice No. CN103881804B discloses
A kind of method of coldly-squeezed sesame oil, although obtaining the sesame oil of higher quality, oil pump capacity is even less than the 30% of sesame weight,
It is calculated according to sesame oil-containing 50%, oil yield is only 60%.In addition, having, researches show that sesame oil made from cold-press is oxidation-stabilized
Property is weaker, and oxidation induction time only has 4.43 hours, far below 13.46 hours [Liu Yulan, Chen Liuyang, Wang of hot moulding method
Moral is learned, waits influence [J] the Journal of Agricultural Engineering of difference squeezing process to sesame oil and sesame-send cake quality, 2011,27(6):
382-386] and water substitution [Liu Yulan, Chen Liuyang, Wang Xue moral sesame variety and oil-producing technique are to sesame within 23.15 hours
Influence [J] Chinese oil of sesame oil quality, 2010,35(2): 6-10].
Summary of the invention
In view of the deficiencies of the prior art, it is an object of the present invention to provide a kind of methods of sesame oil processing, to realize grease
Recovery rate is high, grease thermal stability is strong, heat-sensitive ingredients destroy less, sesame protein invariance.
The technical solution adopted by the present invention are as follows:
A kind of processing method of sesame oil, includes the following steps:
(1) sesame is screened, impurity is removed；
(2) drying equipment heated-air drying is used, for drying temperature less than 50 DEG C, sesame moisture is down to 6wt%~10wt%；
(3) it by the sesame after drying, is freezed with nitrogen ultra low temperature, is crushed in a cold or frozen state with Lowtemperaturepulverizer；
(4) water is added into the black sesame powder after Freezing smashing, is heated to 40-50 DEG C, and phosphorus acid for adjusting pH is added, be gently mixed
60-90 min；
(5) oil separation.
The revolving speed of Lowtemperaturepulverizer is 16000-22000r/min, time 20-60s in step (3) of the present invention.
When step (3) Lowtemperaturepulverizer of the present invention is crushed with liquid nitrogen pump into Lowtemperaturepulverizer liquid nitrogen, amount of infusion
For 3-4 L/min.
The ratio by mass of black sesame powder and addition water is calculated as 1:(0.8-1.2 in step (4) of the present invention).
It is 4.8-5.2 that step (4) of the present invention, which adjusts pH,.
Mixing speed is 10-80r/min in step (4) of the present invention.
In step (5) of the present invention oil be separated into routinely convert slurry stir oil, oscillation point oil, an oil skimming treatment process carry out an oil
From.
The present invention has the advantage that (1) whole process does not pass through high-temperature process, and heat-sensitive ingredients change in sesame oil
It is few；(2) there is no thermal denaturations, subsequent extracted to utilize simple, comprehensive utilization value height for protein.(3) phosphoric acid, which is adjusted to pH, is
4.8-5.2 advantageously reduces the emulsification of protein, reduces the difficulty of oil separation.(4) oil yield is high.Sesame is in Freezing smashing mistake
Cheng Zhong, grease are also frozen, and no fever, oil-water emulsion is few, and separative efficiency is high.(5) oil quality is high, and thermal stability is strong.
Using sesame oil produced by the invention, oil is limpid, and oxidation stability is high, and oxidation induction time reaches 25.4-
28.3 hours, oil yield was greater than 92%, the ratio calculation of above-mentioned oil yield practical oil yield and sesame raw material theory oil content.
