Description

A kind of grape seed oil and preparation method thereof
Technical field
The invention belongs to food processing fields, and in particular to a kind of grape seed oil and preparation method thereof, especially a kind of work The property high grape seed oil and preparation method thereof of ingredient especially polyphenol content.
Background technology
With the continuous improvement of society and living standards, the eating habit of people is also changed, and is eaten and drunk immoderately and is caused very More people are suffering from " three high diseases ", i.e. hyperglycemia, hypertension and hyperlipidemia.Wherein, hyperglycemic patients are most commonly seen, need to strictly control Diet, low sugar less salt, severe patient also need to take hypoglycemic agent.This is but also many hyperglycemic patients all select less in terms of diet It drains the oil or even does not drain the oil.
Grape seed oil is the advanced food by making grape wine or the further processing of the by-product grape pip of juice extracting obtains With oil.Grape seed oil is full of nutrition, and unsaturated fatty acid is up to 90% or more, predominantly linoleic acid (70% or more), oleic acid, palm fibre Palmitic acid acid and stearic acid.Linoleic acid is essential aliphatic acid for human body, is one of the important composition for constituting human cell membrane and skin, can tie up The blood fat balance of adult is held, cholesterol is reduced, improves angiocardiopathy.Also contain phenolic compound in grape seed oil, does not have such as Gallate-based, catechin, epicatechin, procyanidine etc., research in recent years have reported these phenolic compounds with extensive Bioactivity:Anti-oxidant, anticancer, radicals scavenging effect, anti-inflammatory, antiviral, hypoglycemic and other effects.In addition, grape pip Also contain in oil phytosterol, squalene, a variety of liposoluble vitamins (A, E, D, K, P) and various trace elements (Ca, Fe, Zn, Mn、Cu)。
Horse tinkling of pieces of jade etc. studies the antioxidation of mice organs grape seed oil, measures mouse tissue lipid peroxidation Matter content, paddy Guang peptide peroxidase and superoxide dismutase activity.The result shows that grape seed oil experimental group small white mouse Liver, kidney device glutathione peroxidase, superoxidase activity be higher than control group, the content of the malonaldehyde of each internal organs is bright It is aobvious to be less than control group, it was demonstrated that grape seed oil has certain antioxidation.Lutterodt et al. has studied cold press Chardonnay, horse Si Kadan, the free radical scavenging ability of ruby and Kang Kede grape seed oils indicate seed oil to DPPH freedom with Trolox equivalents The removing power of base, the results showed that the DPPH free radical scavenging activities range of seed oil is from 0.07 to 2.22mmol/g.Grape seed oil nutrition Value and medical function obtain domestic and international medical field and the abundant affirmation of nutritionist.
Currently, grape seed oil on the market mostly uses cold press and solvent extraction technology.Squeezing method oil yield is not high, solvent leaching Going out method, there are problem of solvent residual.Aqueous enzymatic method is a kind of environment-friendly type grease extractive technique, by crushing and digesting come degrading plant Cell wall discharges the grease in oil plant cell.Aqueous enzymatic method has the following advantages with respect to traditional handicraft:High temperature is avoided to live material The influence of property ingredient, free oil yield is higher, lighter color, and protein denaturation degree is small, and is conducive to environmental protection and grease work The sustainable development of industry.In recent years, lot of documents constantly carries out process optimization for aqueous enzymatic method grape seed oil recovery rate is improved.Lee Dan Dan (2017) digests 9h using complex enzyme (cellulase, pectase, zytase, trypsase), and freeze-thaw method demulsification is fuel-displaced Rate is 9.947%, acid value 0.52 (KOH)/(mg/g).High fine jade etc. (2009) is using enzymolysis and organic solvent extraction gained grape Seed oil extract rate reaches 88.9%, acid value 0.43 (KOH)/(mg/g);Hu Bin etc. (2015) first uses cellulase degradation 2h, after Using neutral protease enzymolysis 1.5h, grape seed oil recovery rate is 77.48%;Ultrasound pretreatment 15min on this basis, extraction Rate is up to 87.65%;Microwave demulsifying is then used, recovery rate is up to 93.83%, acid value 2.16 (KOH)/(mg/g).Lv Shanshan is adopted With steam pre-treatment knot and cellulase/protease hydrolytic 8h, oil yield 13.26%, acid value 1.24 (KOH)/(mg/g).
But the study of active components for relating to the obtained grape seed oil of enzymolysis process is relatively fewer, and the phenol in grape seed oil Substance is its main antioxidant, is easiest to that oxidation, degradation occurs in enzymolysis process.Therefore, urgent need is a kind of to carry Active constituent especially polyphenol content in high grape seed oil, while taking into account the preparation side of the grape seed oil of grape seed oil recovery rate Method.
