Processing technique for preparing debitterized lemon seed oil by cold pressing

Abstract

The invention relates to a processing technique for preparing debitterized lemon seed oil by cold pressing. The processing technique comprises the following steps of 1), screening, performing acidolysis and enzymolysis on a lemon seed: enabling the lemon seed to be suitable for oil pressing; 2), three-stage low-temperature oil pressing of the lemon seed; (3), debitterizing of coldly-pressed lemonseed oil: firstly carrying out enzymolysis on a bitter substance by using a debitterizing compound enzyme, then carrying out adsorptive debitterization by using a solid debitterizing agent, and finally, adding sucrose and beta-cyclodextrin; 4), refining operation of degumming, deacidifying, deodorization, decolorization and the like of the debitterized lemon seed oil. A raw material, to which theprocessing technique relates, is the intact or crushed lemon seed; the processing technique belongs to the reutilization of agricultural waste; the raw material is extremely low in cost and is used for developing edible oil; not only can the pollution by the agricultural waste be avoided, but also the downstream industrial chain of a lemon fruit can be completed. The method for producing the oil from the lemon seed by the cold pressing and a debittering technique thereof, to which the invention relates, are low in consumable-material price, simple in device and technical process and easy to popularize and a developed edible oil product is up to the standard of second-grade edible oil and high in nutrient value and has a wide commercial application prospect.

Description

technical field [0001] The invention relates to a low-temperature cold pressing and debittering process of lemon seed oil, which belongs to the field of edible oil production and processing. Background technique [0002] Lemon (Citrus limon (L.) Burm.F.) belongs to the evergreen small tree plant of Rutaceae citrus, and is widely planted in tropical and subtropical regions of the world. Lemon fruit is bright in color and has a strong sour taste. It is rich in various vitamins and mineral elements, as well as antioxidant substances such as limonin, flavonoids and phenolic acids, and has high nutritional value and health care functions. In recent years, my country's lemon industry has shown a trend of accelerated development, and the output of fresh fruit has increased from 302,000 tons in 2010 to nearly 700,000 tons in 2016; in addition to fresh fruit sales and exports, the total annual processing of lemons in my country has also increased from 150,000 tons in 2010 It rose to ...
