Problems solved by technology

However, considering the complexity and particularity of the actual production process, the above methods are difficult to apply on a large scale due to more or less application limitations. At the same time, although the biodegradation method has higher degradation efficiency, it also has the risk of introducing new pollutants. May cause new food safety problems, etc.

Embodiment 1

[0027] Embodiment 1 A kind of preparation of nanoemulsion inhibitor

[0028] (1) Beat 200g of fresh bergamot, add 1000ml of pure water, and extract the volatile oil by microwave-assisted distillation; the microwave power is 600W, and the extraction time is 1.5h, and the volatile oil is collected;

[0029] (2) Lactoferrin is dissolved in neutral phosphate buffer to obtain a solution with a protein concentration of 0.5%. Get bergamot volatile oil 0.1g and 0.6g camellia oil and mix evenly to form a mixed oil. Mix the mixed oil with 4.3g The protein solutions were mixed, ultrasonically treated for 5 minutes, and then homogenized for 20 minutes with a high-pressure homogenizer under the condition of 50Mpa to obtain a lactoferrin-based bergamot volatile oil nanoemulsion.

[0030] The obtained nanoemulsion inhibitor is placed at room temperature for more than 30 days, and its properties do not change, it can be miscible with water in any proportion, and its stability is very good. I...

[0031] Embodiment 2 Preparation of a nanoemulsion inhibitor

[0032] (1) Grind 100g of dried bergamot, add 3L of pure water, and extract the volatile oil by microwave distillation; the microwave power is 900W, the extraction time is 2h, and the volatile oil is collected;

[0033] (2) Lactoferrin is dissolved in neutral phosphate buffer to obtain a solution with a protein concentration of 0.3%. 1.0g bergamot volatile oil is mixed with 5.3g camellia oil to form a mixed oil, and the mixed oil is mixed with 33g protein The solutions were mixed, ultrasonically treated for 10 minutes, and then homogenized for 15 minutes with a high-pressure homogenizer under the condition of 75Mpa to obtain the bergamot volatile oil nanoemulsion.

[0034] The obtained nanoemulsion inhibitor is placed at room temperature for more than 30 days, and its properties do not change, it can be miscible with water in any proportion, and its stability is very good. In specific applications, it can be diluted...

Embodiment 3

[0035] Embodiment 3 Preparation of a nanoemulsion inhibitor

[0036] (1) Beat 2kg of fresh bergamot, add 15L of pure water, and extract the volatile oil by microwave distillation; the microwave power is 1500W, the extraction time is 1.5h, and the volatile oil is collected;

[0037] (2) Lactoferrin is dissolved in neutral phosphate buffer to obtain a solution with a protein concentration of 0.2%. 0.5g bergamot volatile oil is mixed with 2g camellia oil to form a mixed oil, and the mixed oil is mixed with 12g protein solution Mix and ultrasonically treat for 20 minutes, and then use a high-pressure homogenizer to homogenize for 6 minutes under the condition of 80Mpa to obtain bergamot volatile oil nanoemulsion.

[0038] The obtained nanoemulsion inhibitor is placed at room temperature for more than 30 days, and its properties do not change, it can be miscible with water in any proportion, and its stability is very good. In specific applications, it can be diluted multiple times...

Abstract

The invention discloses an inhibitor for inhibiting production of vomitoxin by fusarium graminearum, and belongs to the field of feed additives. The invention is based on a nanoparticle technology, natural protein is used as a carrier to nano-modify volatile oil, and camellia oil is used as an oil phase to prepare the nanoemulsion inhibitor that significantly reduces the production of the vomitoxin by the fusarium graminearum to provide a novel option for inhibiting the production of toxins by fungi and reducing hazards of the mycotoxins.

Description

technical field [0001] The invention relates to an inhibitor for inhibiting the production of vomitoxin by Fusarium graminearum, belonging to the field of feed additives. Background technique [0002] Fusarium graminearum is one of the main pathogens causing head blight in crops, and its secondary metabolite is vomitoxin. Vomitin, also known as deoxynivalenol (DON), chemically named 3α, 7α, 15-trihydroxyfusarium-9-en-8-one, has great safety hazards to humans and animals , the EU classification standard is a third-class carcinogen. Once DON contaminates the feed, it will not only cause huge economic losses, but it is more likely to enter the food chain and threaten the health and safety of humans and animals. At present, there are few efficient detoxification methods in my country to deal with the threat of vomitoxin to feed safety. [0003] The current methods for inhibiting the production of vomitoxin by Fusarium graminearum mainly use biological methods to obtain some s...
