It is described as east olive oil；The fatty acid composition mid-oleic of pecan oil is higher than 67%, the sum of oleic acid, linoleic acid, linolenic acid
More than 90%, meet very much human health needs；Also contain unique physiological activator such as hickory nut glucoside, mountain in pecan oil
Walnut saponin, hickory nut polyphenol, squalene etc.；Therefore pecan oil medically also controls cardiovascular disease for auxiliary, promotes bone
Bone and nervous system development, anti-oxidant and adjusting immune function, pre- anti-cancer etc.；In addition, in medicine external application and cosmetics
There is special efficacy；Pecan oil iodine number is low, smoke point is high, stability is good；It is particularly good for frying baked goods flavor, therefore mountain core
Peach oil is the xylophyta oil of a kind of high-quality, high nutritive value, can exclude the impurity of intravascular metabolism, keep blood net
Change, provide new blood for brain, though the nutrient of walnut oil is high, existing squeezing mode can be destroyed more in walnut now
Weight nutritional benefit ingredient, greatly reduces the healthy nutritive value of walnut oil.
China's pecan oil production level falls behind, and is mostly workshop-based small factory, continues to use the technique and equipment of small oil refining, equipment letter
Plain, low output, it is backward in technique be difficult to produce high-quality pecan oil, refining consumption is big, level of comprehensive utilization is low, of poor benefits, therefore,
Great-leap-forward development is realized in the production of an urgent demand pecan oil.
Summary of the invention
The purpose of the present invention is overcoming disadvantages mentioned above, provide a kind of pressing method of pecan oil, improve oil yield and
Oil quality out.
The purpose of the present invention can be achieved through the following technical solutions: a kind of pressing method of pecan oil, feature exist
In, comprising the following steps:
