Embodiment 1

[0015] The preparation of embodiment 1 bamboo vinegar antibacterial liquid

[0016] With 500ml of bamboo vinegar (Suichang Shenlonggu Bamboo Charcoal Co., Ltd., batch number 20081021A) at 50 DEG C, distillation is under the condition of 0.09MPa vacuum, until the volume of the distillate is 80% of the stoste, i.e. 400ml, then stop, the distillate is for the extract. The distillate was uniformly mixed with sweet orange essential oil at a volume ratio of 500:1 at 20° C. to obtain 400 ml of bamboo vinegar antibacterial liquid. The bamboo vinegar antibacterial liquid obtained in this embodiment is transparent in color, completely removes the burnt odor of the bamboo vinegar stock solution, and has a pleasant fragrance.

[0017] The strains to be tested were: Escherichia coli, Staphyloccocus aureus, Pseudomonas aeruginosa, Saccharomyces cerevisiae, Candida albicans, Aspergillus niger ), respectively activated with their appropriate culture medium, and then prepared with sterile wa...

Embodiment 2

[0020] The preparation of embodiment 2 bamboo vinegar antibacterial liquid

[0021] With 500ml of bamboo vinegar liquid (Suichang Shenlonggu Bamboo Charcoal Co., Ltd., batch number 20081021A) at 60 ℃, under the condition of vacuum degree of 0.09MPa, distill until the volume of distillate is 80% of stoste, i.e. 400ml, then stop, and the distillate is for the extract. The distillate was uniformly mixed with sweet orange essential oil at a volume ratio of 500:2 at 20° C. to obtain 401 ml of bamboo vinegar antibacterial liquid. The bamboo vinegar antibacterial liquid obtained in this embodiment is transparent in color, completely removes the burnt odor of the bamboo vinegar stock solution, and has a pleasant fragrance.

Abstract

The invention discloses a bamboo vinegar antibacterial liquid, which is prepared by the following steps: distilling a raw material of a bamboo vinegar liquid at 50 to 80 DEG C under a reduced pressure; stopping distilling until the volume of a distilled liquid is 60 to 90 percent of that of the raw material bamboo vinegar liquid; mixing the distilled liquid and a citrus essential oil uniformly in a volume ratio of 500:1 to 10 to obtain a mixed liquid, namely the bamboo vinegar antibacterial liquid. The preparation method of the invention can not only remove the thick smoke burning smell and the penetrating odour of the bamboo vinegar liquid, but also change the colour of the bamboo vinegar liquid into transparent; moreover, compared with the stock solution of the bamboo vinegar liquid, the bamboo vinegar antibacterial liquid has the antibacterial and bactericidal properties which are not weakened, and can be widely used in the field of foods, daily use chemicals, medicaments and the like.

Description

(1) Technical field [0001] The invention relates to a preparation method of bamboo vinegar antibacterial liquid, in particular to a preparation method of bamboo vinegar antibacterial liquid with low smoke burnt smell and pungent smell. (2) Background technology [0002] Bamboo vinegar liquid, also known as bamboo vinegar liquid, is a by-product of the bamboo charcoal firing process. During the firing process of bamboo charcoal, the smoke generated by the decomposition of bamboo at high temperature is collected, and the liquid substance obtained by condensing this gas at room temperature , namely " thick bamboo vinegar liquid ", just the raw material used of the present invention---bamboo vinegar liquid. Bamboo vinegar contains 40-60% organic components, and it usually requires refining processes such as standing and distillation for specific applications. The refined bamboo vinegar can be used for agricultural purposes, and can also be made into household cleaning products. ...
