Embodiment 1

[0034] The preparation of embodiment 1 sauce residue waste oil glyceride

[0035] S1: Dry the discarded soy residue collected from the soy sauce production plant in a blast oven at 100°C for 1 hour, then use a small oil press to squeeze the oil for 3 consecutive times, and finally use a filter to remove the residual impurities. Soy sauce waste oil is obtained;

[0036] S2: Add waste oil from soy sauce into the reaction kettle, and continue for 30 minutes at a temperature of 70°C and a vacuum of 0.12 MPa to remove volatile impurities; when the temperature of waste oil from soy sauce drops to 60°C, add 2 %m / m lipase RM IM and 15% m / m glycerin, carry out the continuous reaction under the condition of vacuum of 0.10MPa and nitrogen gas, until the acid value of the waste oil of soy sauce drops to 4KOH / mg.g When the time is below, the reaction is stopped, and the lipase RM IM is filtered through a 200 mesh sieve to obtain the residue waste oil glyceride.

Embodiment 2

[0037] The preparation of embodiment 2 sauce residue waste oil glyceride

[0038] S1: Dry the discarded soy residue collected from the soy sauce production plant in a forced air oven at 100°C for 1 hour, then use a small oil press to squeeze the oil for 2 consecutive times, and finally use a filter to remove the residual impurities. Soy sauce waste oil is obtained;

[0039] S2: Put the waste oil from soy sauce into the reaction kettle, and continue to remove volatile impurities under the condition of temperature at 75°C and vacuum degree of 0.09MPa for 60 minutes; when the temperature of waste oil from soy sauce drops to 55°C, add 1 %m / m lipase RM IM and 10% m / m glycerin, carry out the continuous reaction under the condition of vacuum of 0.08MPa and nitrogen gas, until the acid value of the waste oil of soy sauce drops to 4KOH / mg.g When the time is below, the reaction is stopped, and the lipase RM IM is filtered through a 200 mesh sieve to obtain the residue waste oil glyceri...

Embodiment 3

[0040] The preparation of embodiment 3 biological pesticides

[0041] Example 3 The biopesticide containing glyceride of waste oil from soy sauce comprises the following components in parts by weight: 25 parts of glyceride from waste oil from soy sauce, 50 parts of Beauveria bassiana spore powder, 15 parts of xanthan gum, glutathione 3 parts, 6 parts of spermine, 70 parts of diatomaceous earth and appropriate amount of water.

[0042] Preparation method: Mix the waste oil glyceride of sauce residue, Beauveria bassiana coccidioides spore powder, xanthan gum, auxiliary stabilizer, diatomaceous earth and water, stir evenly, carry out wet granulation, and make it with a diameter of 0.2-0.4cm Granules are vacuum-dried until the water content is 8-15%wt to obtain the biopesticide.

Abstract

The invention discloses a biological pesticide containing soy sauce residue waste oil glyceride and a preparation method thereof. The biological pesticide comprises the following components in parts by weight: 20-30 parts of soy sauce residue waste oil glyceride, 40-50 parts of beauveria bassiana spore powder, 10-20 parts of xanthan gum, 5-10 parts of auxiliary stabilizer, 60-80 parts of diatomite, and appropriate amount of water. The biological pesticide has the advantages of being high in insecticidal activity, fast and stable in insecticidal effect, long in residual life, environment-friendly, efficient, low in toxicity and low in residue; the activity of the beauveria bassiana spore powder can be effectively maintained, the storage time of the spore is prolonged, and the live spore rate is improved, the biological pesticide stability is improved; and recycling of the soy sauce residue waste oil can be realized, the energy-saving and environment-protecting concept can be satisfied,and the more extensive application of the beauveria bassiana can be promoted.

Description

technical field [0001] The invention belongs to the technical field of bio-pesticide preparation, and in particular relates to a bio-pesticide containing glyceride of soy residue waste oil and a preparation method thereof. Background technique [0002] Biopesticide refers to a type of pesticide preparation that uses living organisms or their metabolites to control pests, germs, weeds, nematodes, rodents and other harmful organisms. Biological pesticides include microbial-derived pesticides, plant-derived pesticides, animal-derived pesticides and genetically modified Compared with chemical pesticides, biological pesticides have the following advantages: 1) strong selectivity, relatively safe for humans, animals and various beneficial organisms, and protect natural enemies; 2) have little impact on the ecological environment; 3) can induce pests Epidemics etc. [0003] Microbial pesticides are an important part of biopesticides. They are made from microbial groups whose metab...
