Embodiment Construction

[0033] The present invention utilizes star anise oil to extract waste liquid and prepares the method for food preservative, comprises the following steps:

[0034] a. extract anisaldehyde, anisone and anisic acid mixture from star anise oil extraction waste liquid, comprise the following steps:

[0035] (1) Collect the water phase distillate, the water phase distillate is the water phase distillate flowing out from the oil-water separator of the star anise oil extraction tank, or the brownish yellow turbid waste liquid in the star anise oil extraction tank The water phase distillate collected after re-distillation; wherein the water phase distillate flowing out of the oil-water separator of the star anise oil extraction tank is a colorless transparent liquid, which is the remaining distilled water after the star anise oil is separated, and dissolved in this water There are volatile components of star anise, and its main components are anisaldehyde, anisone and anisic acid; amo...

Abstract

The invention provides a method for preparation of a food preservative by extracting waste liquid by using star anise oil. The method includes the steps that a water phase distillate flowing from an oil-water separator of an star anise oil extraction tank or a water phase distillate collected after re-distillation of claybank muddy waste liquid in the extraction tank is added with sodium chlorideor potassium chloride, a mixture of anisic aldehyde, anisic ketone and anisic acid in the water phase distillate is precipitated, then an organic solvent is added for extraction, then the organic solvent is subjected to reduced pressure distillation to obtain faint yellow oily liquid, the faint yellow oily liquid is cryogenically frozen, precipitated and crystallized and rapidly filtered to obtainthe mixture of the anisic aldehyde, the anisic ketone and the anisic acid, the mixture has antibacterial activity against staphylococcus aureus, escherichia coli, bacillus subtilis, aspergillus niger, aspergillus flavus and penicillium citricum, and has the scavenging effect on DPPH free radical, the aroma is appropriate, and the mixture can be used as the food preservative. The method is easy tooperate, environment-friendly, low in cost, and convenient to use and popularize.

Description

technical field [0001] The invention relates to a method for preparing a preservative, in particular to a method for preparing a food preservative. Background technique [0002] Star anise (Illicium verum Hook.f.) referred to as star anise, commonly known as star anise, is mainly distributed in East Asia, Southeast Asia and America in the world, among which China is the most, followed by Vietnam, Cambodia, Myanmar, Indonesia and other countries and regions. In China, it is mainly distributed in a few provinces such as Guangxi, Yunnan, and Guangdong. Star anise is an important economic tree species in the south subtropical region of China. The essential oil products extracted from star anise are widely used in flavors and fragrances and food industries. [0003] Most of the production of star anise essential oil adopts the traditional steam distillation process. In the steam distillation process, only the oil phase part of the distillate is generally collected as the essenti...
