Summary of the invention
At the deficiencies in the prior art part, the invention provides that a kind of technology is simple, cost is low, can be applicable to pachydermia and thin skin class oranges and tangerines simultaneously, and the tangerine essential oil extraction process that can produce high-quality essential oil.
The present invention is to realize by such technical scheme: a kind of extraction process of tangerine essential oil is provided, may further comprise the steps successively for reaching above purpose:
1), choose the fresh pericarp of citrus fruit, when the white cortex of pericarp internal layer is thicker than 0.5mm, remove white cortex;
2), with above-mentioned pericarp or the pericarp after removing white cortex squeeze, in the time of squeezing the spray high pressure water; Can obtain by an oil-water mixture and a fruit mixture of forming;
3), said mixture is separated, remove the fruit grain, obtain oil-water mixture;
4), above-mentioned oil-water mixture is separated, remove water, obtain oil;
5), above-mentioned oil is carried out the dewax step.
A kind of improvement as tangerine essential oil extraction process of the present invention: step 2) use three rod cane milles to squeeze.
Further improvement as tangerine essential oil extraction process of the present invention: step 3) uses separating centrifuge to separate, and separation factor is 560～580.
Further improvement as tangerine essential oil extraction process of the present invention: step 4) uses disk centrifugal separator to separate, and separation factor is 9000～11000.
Further improvement as tangerine essential oil extraction process of the present invention: disk centrifugal separator is special-purpose mandarin oil separating machine.
Further improvement as tangerine essential oil extraction process of the present invention: citrus fruit is mandarin orange class, tangerine class, orange class, shaddock class, lemon class, high orange class or other mixed citrus fruit.
Tangerine essential oil extraction process of the present invention, technology is simple, easy and simple to handle, production cost is low; Made essential oil product is pure, and natural fragrance is less undermined.Tangerine essential oil extraction process of the present invention is compared with existing milling process, can be from peel of Citrus reticulata Blanco direct disposable extraction essential oil, do not need pericarp is carried out the lime hardening treatment in advance; Therefore keep the fragrance of essential oil preferably, can also simplify production technique.With distillation method method mutually, need not heat, fragrance improves significantly.Compare with Brown technology with FMC, can be applicable to pachydermia and thin skin class oranges and tangerines simultaneously.Tangerine essential oil extraction process of the present invention is fit to China's actual conditions very much, can at utmost bring into play as oranges and tangerines canned by product---the use value of peel of Citrus reticulata Blanco.
Embodiment
