Problems solved by technology

Natural plant essential oil components have the characteristics of strongly inhibiting or killing microorganisms such as fungi, and are effective components of plant antibacterial. In recent years, there have been many studies on extraction and effects, but the study of natural preservatives in my country started relatively late. Mechanism research and application technology It is not deep enough, and the preservation of food, fruits and vegetables, and food is mostly in the experimental stage, and there are no mature products or suitable dosage forms, and it cannot be applied to the preservation of agricultural products in industrialization

example 1

[0018] Example 1: A fumigant containing natural plant essential oil, its main components are: 30 kg of plant essential oil compound; 2 kg of fungicide; 10 kg of oxidant; 40 kg of combustible agent; 15 kg of flame retardant; Kilogram.

[0019] The plant essential oil is one or more of clove oil, mustard oil, cinnamon oil, and citronella oil, and is extracted by rotary evaporator distillation or CO2 supercritical extraction apparatus.

[0020] The fungicide is one or more of imazalil or teketol, systemic broad-spectrum fungicides.

[0021] The oxidant is one or more of sodium chlorite, potassium permanganate or potassium nitrate.

[0022] The combustible agent is one or more of rice straw, rice bran, corncob, and cow dung.

[0023] The flame retardant is one or more of soda lime, sodium carbonate and ammonium chloride.

[0024] The coloring agent is one or more of iron red, grass green, turquoise green and cyan blue.

example 2

[0025] Example 2: A fumigant containing natural plant essential oil, its main components are: 5 kg of plant essential oil compound; 0.2 kg of fungicide; 3 kg of oxidant; 20 kg of combustible agent; 2 kg of flame retardant; Kilogram.

example 3

[0026] Example three: a fumigant of natural plant essential oil, its main components are: 25-kg of plant essential oil compound; 1 kg of bactericide; 8 kg of oxidant; 30 kg of combustible agent; 10 kg of flame retardant; Kilogram.

[0027] The use method of this kind of fumigant containing natural plant essential oil: fully mix the fumigant made into block or powder, and stack it evenly in the main passage according to the required amount, and gradually move from the inside of the warehouse to the door of the warehouse. Heap lit and extinguished the open flame, quickly evacuated the scene, and closed the warehouse door.

Abstract

The invention provides a fumigant containing natural plant essential oil, which comprises the following main components: 5 to 30 parts of plant essential oil compound, 0.2 to 2 parts of fungicide, 3 to 10 parts of oxidant, 20 to 40 parts of combustible agent, 2 to 15 parts of flame retardant and 0.1 to 2 parts of coloring agent. The fumigant has the advantages of wide sterilization spectrum, strong sterilization capability, insusceptibility to producing resistant strains after long-term use, safety, wide use range, capability of being applied to the storage and preservation of various agricultural products, low cost, convenient operation, low investment and easy production. The fumigant has the bacteriostatic effect that the fumigant has preservative fresh-keeping effect on various fruits and vegetables, and after the fumigant is ignited in hermetic space, the whole space can be full of generated smoke in full contact with the surfaces of fruits and vegetables so as to effectively resist the infection of pathogenic fungi and kill pathogens.

Description

technical field [0001] The invention belongs to a fumigant containing natural plant essential oils, in particular to a fumigant containing natural plant essential oils, a preparation method and application in fruit and vegetable storage and preservation. Background technique [0002] Since ancient times, people have used aromatic plants in folk medicine and food preservation. Thymol obtained from thyme, cinnamaldehyde obtained from cinnamon and eugenol obtained from cloves, perilla alcohol and perillaldehyde in perilla have Broad-spectrum antibacterial effect. There are many kinds of Chinese herbal medicines in my country, and its research history is long. Many scholars use natural Chinese herbal medicines to prepare Chinese herbal medicine preservatives with antibacterial effect to treat fruits, and the fresh-keeping effect is very obvious. Xi Yufang (1999) found that 2.5% garlic juice, 10% onion juice and 40% ginger juice have a better effect on the prevention and treatme...
