Benefits of technology

This patented process allows us to make better ways to dispose off or reduce bad smells caused from certain substances found on crops such as peanuts during production without causing damage to our healthy ecosystems. It uses an oxidizing agent called ozonized liquid medicine made up mostly hydrogen peroxide dissolved in ethylene glycol solvent. By adding this mixture to the harvested crop before storage, we get ridged any unhealthier odors associated therewith. Additionally, when treating these crops after being stored at room temperature, residual amounts remain even if some were still alive due to decomposition processes occurring naturally over several months later. Overall, this new technology provides technical benefits including faster and more efficient way to remove unwanted compounds like pesticids while maintaining their beneficial properties.

Problems solved by technology

This patented technical problem addressed in this patent relates to finding an efficient way to reduce or eliminate various types of bacteria called molds from agricultural produce while maintaining good quality fruits like rice.

Embodiment 1

[0026] Example 1: Degradation of toxins in food by ozone water

[0027] Pour the contaminated grain material into the container, mix the grain material with water at a ratio of 1:5, the pH of the material liquid is 8.2-8.5, and let it stand in the container for 10 minutes to soak. For example, take 100g of corn and add 500ml of water to control the pH of the feed solution to 8.2-8.5.

[0028] (1) Formation of ozone water system

[0029] In an open and ventilated environment, turn on the ozone generator, pre-discharge the leather tube connected to the gas outlet of the generator for 1 to 2 minutes under the exhaust system device, and then pass the ozone into the soaked material liquid of Example 1, Maintain the ozone concentration in the aqueous solution at 50 mg / L. Ozone is unstable in water, and the reduction reaction occurs all the time, producing very active and strong oxidizing monatomic oxygen (O), which decomposes bacteria, microbial organic substances and toxins in wa...

Embodiment 2

[0035] Embodiment 2: Absorption treatment of ozone waste gas

[0036] Ozone gas is a harmful gas with a concentration of 6.25×10 -6 mol / L (0.3mg / L) will irritate and damage mucous membrane tissues such as eyes and respiratory system, have negative effects on human health, and cause damage to the environment. If the residual ozone gas in the degradation reaction is not treated, it will overflow into the air. The design is to discharge the residual ozone gas from the experiment through the catheter through the sodium thiosulfate solution. The sodium thiosulfate solution can absorb the ozone gas instead of Will pollute the environment. A small amount of ozone remaining in the grain will be decomposed into oxygen, which will not cause harm to the environment, and is an environmentally friendly and non-hazardous degradation method. The process is: 3Na 2 S 2 o 3 +4O 3 +3H 2 O=6NaHSO 4 .

Abstract

The invention discloses and relates to a method for quickly and effectively degrading deoxynivalenol in food grains, and belongs to the technical field of food safety. The method disclosed by the invention comprises the following steps of (1) pouring polluted food grain raw materials in a container, adding water according to the ratio of the food grain raw materials to the water being (1:5) to (1:6) for soaking the food grain raw materials, and then inletting ozone gas to form an ozone water system for a reaction, wherein the ozone concentration is 50mg/L; and (2) enabling residual ozone gas after the reaction to pass through a sodium thiosulfate solution through a pipeline, wherein the sodium thiosulfate solution can absorb the ozone gas so that environment pollution cannot be caused. According to the method disclosed by the invention, vomitoxin can be degraded by ozone water, the method is simple, the vomitoxin can be quickly, safely and effectively degraded, and the degradation rate can reach 80% or above.
