Abstract

The invention provides a preparation process of allium schoenoprasumL. oil, relating to the food chemistry field. The preparation process is characterized by comprising the following steps: (1) selecting fresh soybean salad oil and small allium schoenoprasumL., cutting off the stalks of the small allium schoenoprasumL. and cutting the leaves of the allium schoenoprasumL. into small sections as narrow and uniform as possible; (2) throwing the fresh soybean salad oil and small allium schoenoprasumL. prepared in the step (1) into a flask in a proportion of 1: 2, putting the flask into an electric jacket and switching on a temperature controller, controlling the temperature at 120-125 DEG C and heating the materials for 2 hours; and (3) filtering, standing and cooling the raw materials heated in the step (2) and taking the upper clear liquor after cooling, thus obtaining the allium schoenoprasumL. oil. The preparation process has the following beneficial effects: the process is simple and practical; the extracted allium schoenoprasumL. oil has pure smell, bright color and long shelf life and is not easy to change taste.

Description

technical field [0001] The invention relates to the field of food chemistry, in particular to a preparation process of shallot oil. Background technique [0002] Allium (Allium, fistulosum) is a perennial herb of the Liliaceae family. It is a seasoning familiar and widely used by Chinese people, especially fresh chives (Allium schoenoprasum L.), which are green in color and have a fresh and fragrant smell. Chives contain a variety of ingredients that are beneficial to the human body, such as sulfides, steroids, flavonoids and nitrogenous compounds. However, fresh green onions have a high water content, are perishable, and their flavor is easily deteriorated, so the shelf life is very short, and the storage conditions are very strict, which is not conducive to transportation and storage. Fresh scallion oil retains the characteristics of shallots to the greatest extent, and its shelf life can be extended, so it has great application prospects in the condiment industry and hea...
