Technical field

The present invention relates to sunflower oil technical fields, and in particular to a kind of preparation method of giving off a strong fragrance sunflower oil.

Background technique

China is not only a populous nation, while being also the big producer and consumption big country of a grain and oil.Edible oil is people The required consumer goods of living, human body thermal energy and essential fatty acid are provided, the absorption of liposoluble vitamin is promoted.As China passes through The rapid development of Ji, living standards of the people increase substantially, and people constantly promote the quality requirement of edible oil.Edible oil market Also passed by the expansion of quantity, the expansion of kind and the big stage of the promotion of quality three, come health, personalization, The developing stage of high-technicalization.The appearance of high-end giving off a strong fragrance oil just embodies these features, because of its pleasant strong perfume (or spice) Taste and liked by the majority of consumers.

Sunflower seeds is rich in unsaturated fatty acid, multivitamin and microelement, be a kind of important edible oil materials it One.In recent years, the continuous development of Chinese sunflower seeds industry is grown, and foreign trade scale steps up.Sunflower oil is rich in a variety of The nutriment beneficial to human body, such as linoleic acid, vitamin E, carrotene, and human consumption's absorptivity of sunflower oil Up to 96% or more.Research points out that often edible sunflower oil can protect skin health, enhances human immune system's function, changes Mercy cranial vascular disease, the generation of the diseases such as prevention.Before the consumption figure of sunflower oil in the international market occupies the world Column, wherein Japan, the consumption proportion of South Korea it is high by 70%.The annual consumption of China's sunflower oil had reached 800,000~90 in recent years Ten thousand t.The raising of appearance and popularization and target level of product quality however as full refining technology, sells currently on the market Full refining sunflower oil has lost its giving off a strong fragrance flavor, and whether what consumer cannot be bought by sense organ intuitive judgment is pure Sunflower oil, the decline and market for directly resulting in consumption figure is lost, and not only causes resource and the energy in the overrefinement of grease Waste aggravates environmental pollution, increases grease loss, and have lost the natural beneficial micronutrient in grease, and can not keep away Generate new nuisance with exempting from.Frying seed is the critical process for producing giving off a strong fragrance sunflower oil, the generation of sunflower oil fragrance and stir-fry seed Temperature has direct relation.Temperature is too low, and fragrance is thin；Temperature is too high, and oil plant is easily burnt burnt and can generate harmful substance, therefore wants Strict control fries well the temperature and time of seed.Supercritical CO₂Fluid extraction technology, has simple process, and organic solvent-free is residual It stays, the incomparable advantage of traditional handicrafts such as operating condition is mild.In the production of grease, it overcomes solvent extraction method point From needing distillation to heat in the process, the shortcomings that grease is oxidizable rancid, and there are dissolvent residuals；Squeezing method low yield is also overcomed, essence Technique processed is cumbersome, the undesirable disadvantage of product color, and obtained oil and fat product quality is high.

Summary of the invention

Shortcoming present in view of the above technology the present invention provides a kind of process safety, prepares convenient and fast giving off a strong fragrance The preparation method of sunflower oil.

The technical solution adopted by the present invention to solve the technical problems is: a kind of preparation method of giving off a strong fragrance sunflower oil, packet Include following steps: A, clear up impurity elimination: selected sunflower seeds carries out cleaning removal impurity, all kinds of miscellaneous in the sunflower seeds after clearing up impurity elimination Matter is less than 1%；B, soften: moisture regulation is carried out to the sunflower seeds after removal impurity；C, it peels off: the sunflower seeds after softening is shelled Shell machine is peeled off；D, Kernel-hull separation: Kernel-hull separation is carried out to the mixture after peeling off, so that rate of kernel in hull≤0.9%；E, It is broken: the polly seed nucleole obtained through Kernel-hull separation is crushed；F, branch: by a certain percentage by polly seed nucleole after crushing It is divided into polly seed nucleole main road and polly seed nucleole path；G, it crushes: polly seed nucleole main road being crushed, the powder of polly seed nucleole main road Broken degree is 40~60 mesh；H, supercritical extract: smashed polly seed nucleole main road is carried out at supercritical carbon dioxide process extraction Reason, obtains polly seed nucleole main road crude oil；I, it fries seed: polly seed nucleole path being carried out to fry seed processing；J, it squeezes: to the certain herbaceous plants with big flowers after stir-fry seed Flower seed benevolence path carries out squeezing and takes oil, obtains polly seed nucleole path crude oil；K, sedimentation filtration: by polly seed nucleole main road crude oil and certain herbaceous plants with big flowers Flower seed benevolence path crude oil mix, then through oil-filtering box at 10~20 DEG C natural subsidence 48~72 hours；L, degumming: to through settling Grease after filter carries out aquation degumming process；M, it dewaxes: dewaxing treatment being carried out to the grease after degumming, obtains giving off a strong fragrance sunflower seeds Oil.

Preferably, in the step B, the water content of the sunflower seeds after softening is 6%~10%.

Preferably, in the step C, the whole seed content in the polly seed nucleole after peeling off is 18%~22%.

Preferably, in the step E, polly seed nucleole particle size after cracking is 5~8 valves, and fines content is no more than 6%.

Preferably, in the step F, polly seed nucleole main road ratio be 60%~90%, polly seed nucleole path ratio be 10%~ 40%。

Preferably, in the step H, supercritical carbon dioxide process extraction processing condition are as follows: 25~40kg/h of CO2 flow, Extract 30~40MPa of pressure, 38~50 DEG C of extraction temperature, 120~150min of extraction time.

Preferably, in the step I, seed condition is fried are as follows: fry 140~160 DEG C of seed temperature, fry 20~30 min of seed time.

Preferably, in the step J, squeezing takes deep-fried twisted dough sticks part are as follows: enters to squeeze 110~130 DEG C of temperature, enters to squeeze moisture 3~5%.

Preferably, in the step L, aquation de-alkali additives are as follows: 50~80 DEG C of hydration temperature, 15~40min of hydration time.

Preferably, in the step M, dewaxing treatment condition are as follows: filter aid is diatomite, and crystallization temperature is 10~30 DEG C, Growing the grain temperature is 5~10 DEG C.

Compared with prior art, the present invention the beneficial effect is that: the preparation method of giving off a strong fragrance sunflower oil provided by the invention, Raw material is divided into size two-way, path carries out stir-fry seed and obtains strong fragrance, and stir-fry seed temperature and stir-fry seed time are reasonable, reduce energy The consumption of amount；Main road uses supercritical carbon dioxide extraction method, environmental-friendly, can compared with traditional grease preparation technique Protect physiological activator；Last only to carry out sedimentation filtration, degumming and dewaxing technique, appropriateness refines, and remains more vitamin E Etc. nutritional ingredients, safe and reliable, power consumption of polymer processing and pollution it is lower.
