Abstract

The invention discloses a method for preparing nutmeg oleoresin by using a subcritical fluid. The method comprises the following steps: pretreatment, vacuum-pumping, extraction, desolvation, product collection and residue processing. The method for preparing the nutmeg oleoresin by using the subcritical fluid can be carried out under medium temperature condition, an active substance in an oil material cannot be destroyed, so that local flavor of nutmeg can be completely kept, quality of the nutmeg is good, oil extraction rate is high, and problems of loss of the nutmeg oleoresin and oxidative deterioration due to high temperature can be solved. The method uses unique dissolving characteristic of butane to effective components of the nutmeg oleoresin, performs extraction and separation for the nutmeg oleoresin, realizes solvent recycling, and increases utilization rate of the raw material; at the same time, butane has low boiling point, strong dissolvability and low critical pressure, technological condition is mild, production equipment requirement is reduced, safety performance of the production equipment is enhanced, and the method is suitable for large scale production.

Description

technical field [0001] The invention relates to a method for preparing nutmeg oleoresin, in particular to a method for preparing nutmeg oleoresin by utilizing a subcritical fluid. Background technique [0002] Nutmeg is the dried kernel of Nutmeg, a plant of the Myristaceae family. Its kernels can be used as medicine. The main effects are reflected in the digestive system. Circulation and other aspects also have certain pharmacological effects. At the same time, nutmeg is also a kind of precious spice plant, which is an edible spice allowed to be used in my country according to GB2760-86. The traditional method of using nutmeg is to directly add or make nutmeg powder and add it to food, which is easy to leave residues in the food. In industrialized mass production, direct addition or crushing is prone to quality and safety problems; nutmeg oleoresin not only retains It has the flavor and taste of nutmeg, will not leave residues in the food to affect the taste, and the dosa...
