CHITOSAN-ENCAPSULED VEGETABLE OIL AGAINST WAREHOUSE PESTS. HYDROGEL CONTAINING THE MIXTURE AND ITS PRODUCTION METHOD

Abstract

The invention is a slow process developed for pest control in agricultural and textile warehouses. It involves an oscillating hydrogel biomaterial. This is an alternative to carcinogenic naphthalene. The product is an ionic gel of bay leaf, cedar, and horse chestnut oils embedded in a chitosan matrix. It is obtained by encapsulating it with a hydrogel. The developed hydrogel structure remains in place for 30 days. It provides controlled release and does not leave toxic residues on target landfill pests. It achieves a 100% mortality rate without fail.

Description

CHITOSAN-ENCAPSULED VEGETABLE OIL AGAINST WAREHOUSE PESTS. HYDROGEL CONTAINING THE MIXTURE AND ITS PRODUCTION METHOD Technical Area 5. This invention offers significant economic benefits for stored agricultural products and textiles. slow-release, biocompatible, used in the fight against pests that cause losses, It is related to a natural hydrogel biomaterial and its production method. Previously, naphthalene and similar substances were commonly used in the fight against pests in landfills. The carcinogenic effects of synthetic pesticides are known. The use of plant essential oils... 10, on the other hand, has a short-term effect due to the rapid evaporation of active ingredients under environmental conditions. This demonstrates that current techniques preserve the stability and control of essential oils. There is a need for solutions that provide release and contain entirely natural ingredients. Purpose of the Invention The purpose of the invention is to blend bay leaf, cedar, and horse chestnut oils into a chitosan matrix. A slow-release formula that encapsulates 15 strands, is harmless to human health and environmentally friendly. The aim is to offer biomaterials. This method preserves the stability of essential oils while providing protective coatings. The duration of effect is extended and there is high mortality against flour / clothing moths. is provided. Explanation of References 20 1: Chitosan matrix 2: Encapsulated essential oil blend 3: Cross-linked porous structure 4: Oscillation channels Description of the Invention 25 The invention relates to the addition of equal volumetric proportions (0.5 ml) of laurel and cedar to a chitosan matrix (1). and horse chestnut oils (2) formed by encapsulation method They are hydrogen. In the production method, a 2% chitosan solution is mixed with acetic acid. It is prepared, an emulsion is formed by adding the oil mixture, and 0.25% sodium is added. It is dried by inducing ionic gelation with tripolyphosphate (TPP). 30. How the Invention Can Be Applied to Industry The invention addresses moth infestations in food storage facilities, textile silos, and museum collection areas. It can be used as a protective biopesticide against pests. 1
