Method for preparing functional oil by segmented solid state fermentation of mixed fungus

Abstract

The invention discloses a method for preparing functional oil by segmented solid state fermentation of mixed fungus, and belongs to the field of processing of edible oil. According to the invention, soybeans are utilized as main fermentation substrates, and are collocated with other oil seeds according to the demand for different functional nutrients, and the segmented solid state fermentation ofthe fungus is utilized and combined with a supercritical extraction fractionation technology, so that the aims of improving the aftertaste of soybean oil and producing different flavors are achieved,and the nutritional value of the oil is improved at the same time. According to the segmented solid state fermentation of the fungus disclosed by the invention, the oil extraction rate is increased; the composition of fatty acids of the oil is improved; the contents of the main flavor substances such as pyrazines, alcohols and phenols are increased; and the sensory functions such as flavor and color of the oil are more in line with the demand of consumers for innovative products. The fermented oil seed meal can be further processed for producing by-products such as functional peptides, and sustainable green development is realized.

Description

technical field

[0001] The invention relates to a method for preparing functional oil by staged solid-state fermentation of mixed fungi, which belongs to the field of edible oil processing. Background technique

[0002] Soybean oil is the vegetable oil with the largest output in the world. The traditional methods of preparing soybean oil include pressing method and extraction method. Nutritional ingredients, but it has strict requirements on the selection of raw materials, and there is a problem of low oil extraction rate, which will greatly increase its production cost. The principle of the extraction method is to extract soybean oil with an organic solvent. The process requires high-temperature deodorization and other refining processes, which will destroy the influential components in the oil, and has higher requirements for later refining. The prior art also discloses the use of water enzymatic method for oil extraction. Although the water enzymatic method is more envir...
