[0031] Preparation of hickory shell smoked liquid with high antibacterial and antioxidative activities

[0032] 1) Pretreatment of hickory nut shells: select non-polluting, mildew-free hickory nut shells, remove surface impurities, and crush to a particle size of 1.5 cm; mix hickory nut shells with sucrose according to the mass ratio of 20:1 to 5:1. Example preferred 10:1.

[0033] 2) Dry distillation preparation of smoked liquid: put the mixed smoked raw materials into the dry distillation kettle to decompose for 45 minutes to prepare a distillation section between 300-450 ℃, and the generated smoke is condensed and collected by a serpentine condenser tube, and left to stand 15h, which is the crude smoked liquid.

[0034] 3) Refining of crude smoked liquid: add n-hexane to the obtained crude smoked liquid according to the volume ratio of 1:2~3, shake for 5 minutes, let it stand for 10 minutes, and remove the n-hexane extract; Partially add ethyl acetate according to the v...

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...
