Abstract
The invention discloses a preprocessing method for squeezing sesame oil. The method includes the steps of 1, sesame screening, wherein sesame seeds which are not full are removed; 2, wet dehulling, wherein cleaned sesames are placed into a strong base-weak acid saline solution with the pH being 7-9 for being soaked, and then alkali liquor is drained off; 3, hot air drying, wherein wet sesame seeds are evenly spread in a drying disc and dried in an electrothermal blowing dry box; 4, stir-frying, wherein dried sesames are placed into an electric heating frying pan to be subjected to stir-frying; 5, steaming, wherein the sesames are placed into a steam cooker, a weak alkaline phosphate buffer solution of certain concentration is added in the processing process of the sesames, saponification is not caused easily through alkalescence, alkalescence is helpful in efficiently removing sour and anxious burnt pungent taste substances in the sesame oil, the dissolution loss of pyrazine baked sweet substances in water is reduced, and thus the flavor can be soft and pure.
Description
Technical field
The invention belongs to sesame oil field, more particularly, the present invention relates to a kind of pre-treating process squeezing sesame oil.
Background technology
Sesame oil is one of main oil crops of China, and containing a large amount of unsaturated fatty acidss, nutritive value is higher, and its strong fragrance is liked by human consumer deeply, especially ground sesameseed oil.At present, the production technique of Oleum Sesami has water substitution, milling process.Traditional water substitution technique is: clear seed, moisten seed, fry seed, raise cigarette, convert slurry and stir the step such as oil, oil separation by oscillation, the ground sesameseed oil produced is with rich flavor, soft, but its labour intensity is large, and produce a large amount of waste water and can not realize continuous prodution, development is restricted.The machine that grew up afterwards squeezes technique: clear seed, fry seed, raise cigarette, modified, squeezing, filtration, the step such as precipitation, although compensate for the deficiency of water substitution, there is automatic control level high, can the advantage such as continuous prodution, but the sesame oil local flavor produced do not have water substitution to produce ground sesameseed oil is soft, pure.
A kind of preparation method of edible vegetable oil is disclosed in Chinese patent application CN101473980A, sesame oil is squeezed by steps such as rinsing, frying, cooling, defibrination, stirrings, oil yield can be improved, reduce production cost, but it is got oil require, under 50-60 DEG C of condition, sesame is worn into sauce, and in defibrination process, add the boiling water that sesame paste weight is 1-1.5 times.
Chinese patent application CN101224022A provides a kind of aqueous enzymatic method, produces the method for sesame protein and sesame oil simultaneously.Similarly, Chinese patent application CN101317610A provides a kind of working method of Semen Sesami Nigrum oil.The two is equally all adopt first sesame to be worn into slurry, then adds the mode that a large amount of hot water carries out getting oil.Above method is all first process by sesame defibrination and then with a large amount of hot water, creates a large amount of waste water, waste residue, processes more difficult, contaminate environment, and cannot realize continuous prodution.
In sum, this area lacks a kind of deficiency overcoming current machine squeezing technique and water substitution technique, produces the preparation method of the sesame oil of similar ground sesameseed oil local flavor under can be continuously produced, do not produce the condition of a large amount of waste water.Therefore, the preparation method of the sesame oil of similar ground sesameseed oil local flavor is produced in this area under can be continuously produced, do not produce the condition of a large amount of waste water in the urgent need to exploitation.
Summary of the invention
Problem to be solved by this invention is to provide a kind of pre-treating process squeezing sesame oil.
To achieve these goals, the technical scheme that the present invention takes is:
Squeeze a pre-treating process for sesame oil, it is characterized in that, comprise the steps:
(1) sesame screening
