[0043] The preparation method of salad oil comprises:

[0044] A. Rapeseed oil is heated to 50°C to 60°C, and ammonia solution is added until the final concentration of ammonia water is 10%w / w to 20%w / w to obtain the primary mixture;

[0045] B. Stir the initial mixture and heat up to 60°C-70°C, add 5%-10% acetic acid and continue stirring for more than 30 minutes, then add sodium bicarbonate to adjust the pH value to neutral to obtain crude oil;

[0046] C, add the potassium chloride solution that temperature is 80 ℃~90 ℃ in crude oil and carry out stirring washing, the mass fraction of potassium chloride solution is 10%~20%; Add distilled water at a temperature of 80°C to 90°C to the oil phase for washing, and then separate the oil phase; repeat washing with potassium chloride solution and distilled water for 2 to 3 times, and finally separate the obtained essential oil;

[0047] D, essential oil is dried to obtain salad oil.

Abstract

The invention discloses a production technology for preparing fresh zanthoxylum bungeanum oil by a pressing method. The production technology comprises the following steps of adding water to zanthoxylum bungeanum raw materials, crushing a mixture of the zanthoxylum bungeanum raw materials and the water to obtain zanthoxylum bungeanum pulp in a physical pressing manner; adding salad oil to the zanthoxylum bungeanum pulp, performing uniform stirring, placing the zanthoxylum bungeanum pulp and the salad oil after being uniformly stirred into an ultrasonic wave reaction tank for soaking, and then performing separation so as to obtain water, crude oil and zanthoxylum bungeanum cake impurities; and performing prefiltration and settling on the crude oil to remove zanthoxylum bungeanum dregs, and then performing rectification and separation to remove moisture so as to obtain high-purity zanthoxylum bungeanum refined oil. According to the production technology disclosed by the invention, fresh zanthoxylum bungeanum is used as a raw material, and a normal-temperature pressing manner is used for extracting the zanthoxylum bungeanum oil, so that the production technology of the zanthoxylum bungeanum oil is optimized, and original natural ingredients and physiological activators in the fresh zanthoxylum bungeanum can be reserved to the maximum extent. The condition that high temperature treatment enables substances of amides, protein and the like in volatile oil to be denatured and lost can be avoided, and the oxidative rancidity of quality of the zanthoxylum bungeanum oil can be effectively controlled; and in the processing technology, a cold pressing method is adopted, so that the extraction time can be shortened, and the economic benefits of products can be increased.

Description

technical field [0001] The invention relates to the technical field of seasoning production, in particular to a production process for preparing fresh pepper oil by pressing. Background technique [0002] Zanthoxylum bungeanum Maxim. is a deciduous shrub or small tree belonging to Rutaceae and Zanthoxylum. The fruit is round and the size of mung bean. When the fruit is ripe, the peel is red or purple, which is called Jiaohong, and the seeds are called Jiaomu. They are all Chinese medicinal materials, which can extract aromatic oil and are commonly used condiments in the family. Zanthoxylum bungeanum can remove the fishy smell of various meats, promote saliva secretion, and increase appetite; appropriate amount of Zanthoxylum bungeanum can dilate blood vessels and lower blood pressure. Fresh Zanthoxylum bungeanum is not easy to preserve, and it is easy to brown and mildew. The storage time at room temperature is only 1-2 days, and the stacking time is no more than 1 day; the...
