Abstract
The invention relates to an extraction-separation method of kiwi fruit seed oil. The method comprises the following steps: (1) carrying out vacuum drying on kiwi fruit seeds for 2 hours and grinding the dried seeds; (2) adding ethanol into the ground kiwi fruit seeds to perform extraction; (3) after stirring, performing centrifugation and collecting lower layer precipitates; (4) performing stirring extraction with water, performing centrifugation, and collecting precipitates; and (5) performing stirring extraction on the lower layer precipitates with n-hexane to obtain n-hexane extract and vacuum concentrating the n-hexane extract, thereby preparing the kiwi fruit seed oil. The kiwi fruit seed oil achieves an extraction rate of 21.3wt%-24.6wt%, a peroxide value of 0.28-0.34mmol/kg, and an acid value (KOH) of 0.36mg/g-0.45mg/g. The eaglewood oil has good quality.
Description
Technical field
The present invention relates to a kind of extraction and separation method of grease, particularly relate to a kind of extraction and separation method of Chinese gooseberry seed oil.
Background technology
Kiwifruit is a kind of common fruit, has extraordinary mouthfeel and nutritive value.Chinese gooseberry seed in Kiwifruit equally also has very high edibleness.Be different from traditional soybean oil, peanut oil, the unsaturated fatty acid content in Chinese gooseberry seed oil is very high, and the ratio of saturated fatty acid is very low, can effectively prevent the generation of relative disease.
Chinese gooseberry seed oil is as the very high oils of a kind of edibleness, and the method for extraction is more, but contains a large amount of middle polarity impurity in the Chinese gooseberry seed oil for preparing of most extracting method, and the existence of these impurity has reduced the quality of Chinese gooseberry seed oil.Therefore need the impurity by first removing middle polarity wherein, just can prepare the Chinese gooseberry seed oil of higher quality.
Summary of the invention
The technical problem solving: Chinese gooseberry seed oil production peroxide value and the higher problem of acid number that conventional extraction and separation method prepares.
Technical scheme: the invention discloses a kind of extraction and separation method of Chinese gooseberry seed oil, preparation method comprises the following steps: Chinese gooseberry seed is carried out vacuum-drying by (1), the vacuum-drying time is 2h, after vacuum-drying, pulverizes; (2) will in the Chinese gooseberry seed after pulverizing, put into ethanol, the mass ratio of Chinese gooseberry seed and ethanol is 1:2, is to stir 1h～2h at 40 DEG C in temperature; (3) carry out centrifugally after stirring, centrifugal rotational speed is 4000rpm, and the time is 10min, centrifugal rear collection lower sediment; (4) water stirs extraction again, and extraction temperature is room temperature, and extraction time is 3h, after extraction, carry out centrifugal, collecting precipitation; (5) lower sediment is stirred to extraction with normal hexane, extracting temperature is 50 DEG C, and extraction time is 2h, after extraction, hexane extract is carried out to vacuum concentration, prepares Chinese gooseberry seed oil.
An extraction and separation method for Chinese gooseberry seed oil, is preferably uniformly dispersed Chinese gooseberry seed when vacuum-drying, avoids piling up.
An extraction and separation method for Chinese gooseberry seed oil, the purity of described ethanol is preferably more than 99%.
An extraction and separation method for Chinese gooseberry seed oil, no longer includes normal hexane taste in being preferably concentrated into vacuum vessel in the time of vacuum concentration.
An extraction and separation method for Chinese gooseberry seed oil, described Chinese gooseberry seed is preferably fresh Chinese gooseberry seed.
Beneficial effect: the Chinese gooseberry seed oil that extraction and separation method of the present invention prepares has higher nutritive value, and its peroxide value and acid number all lower.The yield of Chinese gooseberry seed oil is 21.3wt% to 24.6wt%, and the Chinese gooseberry seed oil peroxide value preparing is 0.28 to 0.34mmol/kg, and acid number (KOH) is 0.36mg/g to 0.45mg/g, has good quality.
