Embodiment Construction

[0016] The following examples will further illustrate the method provided by the invention.

[0017] Implementation example

[0018] 1. Heat 100g of crude oil to 60°C, add 0.35ml of 85% phosphoric acid, keep it warm in a water bath, stir at 60rpm for 15 minutes, let it stand for 30 minutes, add dilute lye with a concentration of 1% to 3%, and cool down to 40°C , let it stand for 60 minutes, centrifuge at 3000 rpm for 10 minutes, and separate the water layer to obtain degummed oil.

[0019] 2. Warm up the degummed oil to 60-65°C, add 0.1% super-alkaline 12°Be'NaOH (stir quickly at the beginning of addition, stir slowly after soap particles appear) 140rpm and stir for 75min to obtain alkali refined oil.

[0020] 3. Heat the alkali refining water bath to 80°C, let it stand for 4 hours, remove the upper layer of clear oil and discard the soapstock, and obtain the alkali refining soap oil.

[0021] 4. Add 10ml of 3% brine to 80°C soap-free oil and stir, let stand for 0.5h to rele...

Abstract

The invention discloses a method for preparing edible vegetable oil with idesia polycarpa crude oil, and belongs to the field of foodstuff. The method comprises the procedures of crude oil phosphoric acid degumming, alkali refining, water washing, salt water debitterizing, activated clay decoloring, vacuum deodorizing and the like. The method is characterized in that the edible vegetable oil is prepared with the idesia polycarpa crude oil through the procedures of degumming, alkali refining, water washing, debitterizing, decoloring and deodorizing. In the technology, bitter principle in the crude oil is removed by adopting hot salt water, so that the removal is thorough, the removing time and the water consumption are saved, and high-quality edible vegetable oil is obtained eventually; and meanwhile, the technological process is simple, the requirements for equipment is not high, and the cost is remarkably reduced. Therefore, the method can have a wide application prospect in the production of idesia polycarpa edible oil.

Description

technical field [0001] The invention belongs to the field of food, and in particular relates to a method for producing edible vegetable oil by using jatropha tomentosa crude oil as a raw material. Background technique [0002] Jatropha Maoye is a unique woody oil plant species in my country. It has the characteristics of wide distribution, low requirements on soil and climate, and strong adaptability. It is suitable for planting in low-quality, barren slopes, tidal flats, and mountains. , easy to promote, and easy to popularize". At the same time, its fruit has a high oil content and is a high-yield, high-value economic crop with great application value and development potential. According to data reports: Jatropha jatropha has a fruit-producing period of up to 70-100 years, the fruit has a high oil content, and the oil yield per plant can reach 200-300kg, especially its oily unsaturated fatty acid is as high as 82% and is rich in linseed oil acid (up to 68-80%) and vitamin...
