Table 5 aqua method extracts Chinese torreya seed oil fatty acid component analysis
From table 4, it can be seen that in the Chinese torreya seed oil physicochemical property of aqua method extraction, acid number (≤3mgKOH/g) and peroxidating
Value (≤9.85mmol/kg) all meets country's edible oil standard (GB2716-2005), shows that aqua method extracts Chinese torreya seed oil quality
Preferably.
Chinese torreya kernel oils and fats contains 6 kinds of main fatty acids as can be seen from Table 5, with linoleic acid, oleic acid, 20 carbon diene
The unsaturated fatty acids such as acid, eicosatrienoic acid are main.These fatty acids are all contained in the Chinese torreya seed oil that aqua method extracts.Fragrant
Chinese torreya seed oil quality is preferable.
Analyzed by orthogonal experiment, find that extraction time and Extracting temperature are the key factors affecting inclusion essential oil.Test
Confirmatory test shows that aqua method optimised process oil extracting rate is 42.23%, higher than result under experiment condition in orthogonal table.Therefore, water preparation
Method extract Chinese torreya seed oil amplify and checking test, determine that final optimization pass process combination condition is: solid-liquid ratio be 1:4, pH be 6, carry
The time of taking is 20min, and temperature is 60 DEG C.
Result above also indicates that, this process repeatability is preferable, and steady quality, Chinese torreya seed oil extraction ratio is higher.This method simultaneously
Extract Chinese torreya seed oil and meet country's edible oil standard.
Above-described embodiment is only used for illustrating the inventive concept of the present invention, rather than the restriction to rights protection of the present invention,
All changes utilizing this design that the present invention carries out unsubstantiality, all should fall into protection scope of the present invention.
