Description
Technical Field
The invention belongs to the technical field of active ingredient extraction, and particularly relates to a preparation method and application of avocado oil rich in furan lipid unsaponifiable matters.
Background
The unsaponifiable matter is a matter which does not react with alkali when the oil and fat are saponified, and is insoluble in water but soluble in ether. The unsaponifiable matter comprises sterol, high molecular fatty alcohol, saturated or unsaturated hydrocarbon, wax, pigment, vitamins, etc., wherein the most important components are squalene, tocopherol, and sterol. Most vegetable oils contain about 1% unsaponifiables.
The content of unsaponifiable matters in the vegetable oil is one of indexes for identifying the quality of the oil. When the vegetable oil is mixed with mineral oil and paraffin, the unsaponifiable matter value of the vegetable oil is increased, so that the purity and the mixing condition of the oil can be identified by measuring the unsaponifiable matters in the oil. In addition, in the soap-making industry, the unsaponifiable value of fats and oils is also often measured to determine whether the fats and oils are suitable for soap-making, and fats and oils having an unsaponifiable content exceeding 2% to 3% are not suitable for soap-making.
The unsaponifiable matter also has quite strong biological activity, and the unsaponifiable matter in the prepared oil or the refined oil can be used for developing foods, health-care foods, medicines and the like. When extracting oil from plant raw materials and preparing unsaponifiable matters in the oil by a traditional method, the oil is usually extracted from the raw materials firstly, an extraction solution is removed, potassium hydroxide and ethanol solution are added into the oil for heating and saponification, after saponification is finished, petroleum ether, diethyl ether and other solutions are used for extraction to obtain extracts of petroleum ether and diethyl ether layers, then the extracts are respectively washed by alkali-containing ethanol and ethanol, and the petroleum ether and the diethyl ether are volatilized to obtain the unsaponifiable matters in the oil.
In addition, there are many other extraction methods in the prior art, for example, chinese patent application CN 103445996 a discloses a method for extracting unsaponifiable matter from shea butter, which comprises the steps of ester exchange, molecular distillation, crystallization, etc., so as to obtain a high-purity unsaponifiable matter composition, wherein the content of unsaponifiable matter in the composition can reach 60%, 70% or even higher, the composition contains high content of triterpene alcohols and sterols, can exist in solid form, and can prolong shelf life, thus being applicable to various uses.
Chinese patent application CN 111012810A is a preparation method of unsaponifiable matter in ginseng seed oil, belonging to the field of preparation methods of ginseng extracts. Processing dry ginseng seeds into powder, adding petroleum ether, extracting by a reflux method, and pouring out a petroleum ether solution after extraction is finished; adding sodium hydroxide and ethanol solution into petroleum ether solution, stirring and heating; standing after heating, and washing a petroleum ether layer with sodium hydroxide and ethanol solution; washing the petroleum ether layer with ethanol solution; concentrating petroleum ether layer under reduced pressure or normal pressure to obtain unsaponifiable matter of ginseng seed oil. The preparation efficiency of unsaponifiable matters in the grease is improved by 20-50%, and the consumption of petroleum ether is reduced by about 50%. The unsaponifiable matter mainly contains squalene, beta-sitosterol and beta-resinol which are detected by gas chromatography and mass spectrometry, and the three substances account for more than 60 percent of the total unsaponifiable matter by a normalization method.
Avocado oil has higher nutritive value, but distillate in the avocado oil refining process is often treated as waste and is not reasonably utilized, so that the avocado resource waste is caused, and economic and environmental burdens are caused by treatment of a large amount of waste. Therefore, in order to more effectively utilize the byproducts in the avocado oil refining process, the invention provides a process for preparing unsaponifiable matters by utilizing the byproducts.
