Benefits of technology

This patented solution involves combining two types of liquids together - one contains germs killing microorganisms while another containing certain pesticidal active ingredients like quaternaries ammonium salts. These mixtures provide effective disinfectants against various pathogens such as those caused by insect bites. They work alongside each other without causing damage if combined properly.

Problems solved by technology

The technical problem addressed for this patented solution is finding ways to prevent or minimizing damage caused from storing and shipping food products containing germs due to their exposure to airborne fungus (Bacillaria) through various methods like adding anti -corrosive agents with different types of ingredients.

Embodiment 1

[0045] Commercially available prochloraz was prepared to the half effect concentration (EC 50) solution, that is, the mass concentration is 0.0088mg / L; the commercially available bamboo vinegar solution is prepared into a half effect concentration (EC 50 ) solution, that is, the mass concentration is 5701.28mg / L.

[0046] The above-mentioned prochloraz solution and bamboo vinegar solution were mixed according to the mass ratio of 1:5, 1:2, 1:1, 2:1 and 5:1 respectively, and then 2.5mL Tween 80 were added and mixed evenly to obtain Composition for preservation and preservation of fruits and vegetables.

[0047] After diluting the composition by 40 times, the growth rate method is used to measure the in vitro antibacterial activity of the apple anthracnose bacteria. Take the logarithmic value of the composition concentration as the abscissa, and take the probability value of the mycelia growth inhibition rate as the ordinate to obtain the toxicity regression equation, correlat...

Embodiment 2

[0052] Commercially available tebuconazole was prepared to the half effect concentration (EC 50 ) solution; the commercially available bamboo vinegar solution was prepared into a half effect concentration (EC 50 )The solution.

[0053] Mix the above-mentioned tebuconazole solution and bamboo vinegar solution according to the mass ratio of 1:5, 1:2, 1:1, 2:1 and 5:1 respectively, then add 2.5mL Tween 80 and mix evenly to obtain Composition for preservation and preservation of fruits and vegetables.

[0054] After the composition is diluted 50 times, the growth rate method is used to measure the in vitro antibacterial activity of the apple anthracnose bacteria. Take the logarithmic value of the composition concentration as the abscissa, and take the probability value of the mycelia growth inhibition rate as the ordinate to obtain the toxicity regression equation, correlation coefficient and EC of the composition to the apple anthracnose bacterium. 50 , see Table 2 for the res...

Embodiment 3

[0059] With acetone, prochloraz is formulated into the prochloraz stock solution that mass concentration is 25g / L;

[0060] Take 10 mL of prochloraz stock solution and dilute it to 1 L with distilled water to obtain a prochloraz solution with a mass concentration of 250 mg / L, which is designated as drug solution 1;

[0061] Dilute the prochloraz stock solution with acetone to obtain a 12.5 g / L prochloraz solution; take 10 mL of the diluted prochloraz solution, add 10 mL of commercially available bamboo vinegar and 2.5 mL of Tween 80, mix well, Dilute to 1L with distilled water to obtain a solution with a prochloraz concentration of 125 mg / L and a 100-fold dilution of bamboo vinegar, which is recorded as liquid 2;

[0062] Dilute the prochloraz stock solution with acetone to obtain a 12.5 g / L prochloraz solution; take 10 mL of the diluted prochloraz solution, add 10 mL of acetic acid and 2.5 mL of Tween 80, mix well, and dilute to 1 L with distilled water , to obtain the proch...

Abstract

The invention provides a composite for antiseptic preservation of fruits and vegetables, comprising 40-80wt% of bamboo vinegar, 1-10wt% of chemical fungicide, 4-20wt% of additive and the balance water. The bamboo vinegar and the chemical fungicide both have the functions of sterilization and fungistasis, and can play the role of the addiction or synergy when being used at the same time, thereby realizing the function of antiseptic preservation and effectively preventing and treating diseases of rot and deterioration of fruits and vegetables caused by anthracnose, black rot, penicilliosis, gray mold, brown rot, soft rot and the like. Experiments show that prochloraz and bamboo vinegar have obvious synergy when being mixed for use by mass percent of 1:5, wherein the co-toxicity coefficient (CTC) can reach 261.23; and tebuconazole and bamboo vinegar also have obvious synergy when being mixed for use by mass percent of 1:5, wherein the co-toxicity coefficient (CTC) can reach 249.49.
