Embodiment Construction

[0033] A kind of method utilizing cinnamon oil to extract waste liquid of the present invention to prepare food preservative comprises the following steps:

[0034] a. Extract trans-cinnamaldehyde and cinnamic acid mixture from cinnamon oil extraction waste liquid:

[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 cinnamon oil extractor, or redistill the brown-black turbid waste liquid in the cinnamon oil extractor The water phase distillate collected last; wherein the water phase distillate flowing out in the oil-water separator of the cinnamon oil extractor is a colorless transparent liquid, which is the remaining distilled water after separating out the cinnamon oil, and the volatilization of cinnamon is dissolved in this water. The main components are trans-cinnamaldehyde and cinnamic acid; the water phase distillate collected after re-distilling the brown-black turbid w...

Abstract

A method of preparing a food preservative through an extraction waste liquid of cinnamon oil. The invention relates to a method of preparing food preservatives. The method includes following steps: (A) employing a water-phase distillate, which is flown from an oil-water separator in a cinnamon oil extractor, or the water-phase distillate, which is collected after a brown-black turbid waste liquid in the extractor is distilled again; (B) adding NaCl or KCl to separate trans-cinnamyl aldehyde and cinnamic acid out from the water-phase distillate; (C) adding an organic solvent to perform extraction, and performing pressure-reduced distillation to the organic solvent to obtain a brown oily liquid; (D) low-temperature freezing the brown oily liquid to precipitate crystals, and quickly filtering the liquid to obtain the trans-cinnamyl aldehyde / cinnamic acid mixture. The trans-cinnamyl aldehyde / cinnamic acid mixture has antibacterial activity on staphylococcus aureus, escherichia coli, bacillus subtilis, aspergillus niger, aspergillus flavus and penicillium citrinum, has a removal effect on DPPH free radicals and can be used as a food preservative. The method is simple in operations, is environment-protective and low-cost, and is convenient to popularize and apply.

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] Cinnamon (Cinnamomum cassia Presl), also known as cinnamon, belongs to the genus Lauraceae, and is mainly distributed in tropical and south subtropical regions. my country is the main producing area of ​​cinnamon, which is mainly distributed in Guangxi and Guangdong, followed by Hainan, Yunnan, and Fujian. The essential oil products made of cinnamon are widely used in flavors and fragrances and food industries. [0003] The production of domestic cinnamon oil all adopts the traditional steam distillation process. In the steam distillation process, generally only the oil phase part of the distillate is collected as the cinnamon essential oil product, and the water phase distillate flowing out from the oil-water separator of the cinnamon oil extractor and the brown-black turbid waste liquid in the cin...
