Safe processing method of high antibacterial and antioxidant activity carya cathayensis shell smoking liquid

Abstract

The present invention discloses a preparing method of high antibacterial and antioxidant activity carya cathayensis shell smoking liquid, and belongs to the technical field of aquatic product processing. The preparing method adopts carya cathayensis shells as a raw material, and includes the following steps: placing the carya cathayensis shells and saccharose in proportion in a distillation apparatus, carrying out dry distillation decomposition and cooling flue gas, thereby obtaining a crude smoking liquid; refining the crude smoking liquid through ethyl acetate, and removing carcinogens with macroporous resin, thereby obtaining the high antibacterial and antioxidation activity carya cathayensis shell smoking liquid. According to the high antibacterial and antioxidation activity carya cathayensis shell smoking liquid, a content of polyphenols is 18.1 to 20.5mg / mL, a content of carbonyl compounds is 9.5 to 10.8 mg / mL, pH value is 2.3 to 2.6, and 3,4 benzopyrene is not detected. The high antibacterial and antioxidation activity carya cathayensis shell smoking liquid can be applied in the aquatic products by atomizing and soaking, has good antibacterial and antioxidant effects, and makes the aquatic product have a rich smoked flavor.

Description

technical field [0001] The invention relates to a method for preparing a food smoked liquid with high antibacterial and antioxidative activity, in particular to the preparation of a food smoked liquid which uses hickory shell wood particles to carry out dry distillation, ethyl acetate refining and macroporous resin to remove carcinogens The method belongs to the technical field of aquatic product processing. Background technique [0002] Aquatic smoked products are favored by consumers at home and abroad because of their unique smoked flavor. Traditionally, the main purpose of using smoke is to prolong the shelf life of aquatic products. Now, in addition to being used for preservation, it is more about the pursuit of the attractive flavor of smoked products. [0003] The traditional smoking method mainly uses smoke produced by slow combustion or incomplete combustion of wood, sawdust, etc., so that aquatic products can lose part of their moisture and be dried. At the same t...
