Description
Technical Field
The invention belongs to the field of grease processing, and particularly relates to a method for degumming sesame oil.
Background
The sesame oil prepared by the methods is thick in fragrance, but the sesame oil is dark in color and poor in transparency due to high-temperature seed frying with skin and high-temperature oil preparation, and the sesame oil cannot be qualified in a 280 ℃ heating test due to contained impurities, particularly colloid impurities such as phospholipid, and floccules and the like appear in the oil and can be used as high-quality finished sesame oil after certain refining treatment.
The sesame oil is turbid and flocculent precipitate is separated under the condition of low temperature or long-time standing, and the main components of the precipitate comprise wax ester, phospholipid, protein, a small amount of free fatty acid and unsaponifiable except glyceride. The main reason for the formation of the precipitate is that colloidal impurities in the oil adsorb the glycerides and then settle at the bottom. The sesame oil cannot be refined by a conventional method, or the fragrance of the sesame oil is lost. The colloid in the crude oil is mainly phospholipid, so the degumming is also called dephosphorization. Other colloids are proteins and their decomposition products, mucilaginous substances and complexes and salts of colloids with various trace metals (Ca, Mg, Fe, Cu). The presence of gums affects the quality and storage stability of the oil. The high content of phospholipid in the finished oil is accompanied by more metal ions, so that the rancidity and color reversion of the finished oil are caused, and the quality of the oil is influenced. Good refining effect can be achieved by filtering sesame oil or filtering sesame oil after cooling, but the sesame oil fragrance is weakened by filtering. The vegetable oil degumming utilizes the hydrophilicity of peptized impurities and the principle that non-hydrated colloid is converted into hydratable colloid under the action of a medium, so that the peptized impurities absorb water to expand, agglomerate and are separated out.
At present, the sesame oil degumming process is less researched, and the researched methods comprise a cold separation method and a hydration degumming method. The sesame oil is refined by a proper method of standing and cold precipitation, but to achieve a better refining effect, the standing and cold precipitation time is long, sometimes even dozens of days of precipitation are needed, even if the sesame oil after cold precipitation refining still appears floccules under certain conditions, and meanwhile, the oil residue obtained by cold precipitation has high oil content, so that excessive loss of the sesame oil is caused. Good refining effect can be achieved by filtering sesame oil or filtering sesame oil after cooling, but the sesame oil fragrance is weakened by filtering. The water degumming is carried out by adding hot water into oil under stirring to make phospholipid absorb water, expand and coagulate, adsorbing other colloid in oil by expanded oil, lowering the solubility of colloid in oil, and separating oil by natural settling. In order to accelerate the sedimentation of the micelle and increase the agglomeration of the micelle, a certain amount of dilute alkali can be added for hydration degumming, so that the content of free fatty acid in the oil can be reduced, and a small amount of soap base formed can agglomerate the colloid, thereby accelerating the sedimentation speed of the micelle; in addition, the existence of the soap base plays a certain role in adsorbing the pigment, and the solubility of the phospholipid in the oil can be reduced at low temperature.
However, hydration degumming can only remove hydratable phospholipids, but not hydratable phospholipids, and the oil after hydration degumming still contains 80-200 mg/kg of phosphorus.
