Abstract: A method for removing pests from harvested vegetables has steps of extracting a first portion of harvested vegetables to obtain a vegetable cleanser, and cleaning a second portion of harvested vegetables with the vegetable cleanser, such that pests residing on the second portion of harvested vegetables are removed from the second portion of harvested vegetables, wherein the first portion of harvested vegetables and the second portion of harvested vegetables independently contain vegetables selected from the group consisting of vegetables belonging to the families of Cruciferae, Compositae, Chenopodiaceae and Amaranthaceae. The aforementioned method is effective at removing pests from harvested vegetables and satisfies urgent needs to reduce use of chemical pesticides.

Abstract: A method of preparing pest repellent for harvesting plants, a method of processing agricultural harvested products, a method of treating vegetable waste, a method for producing a cleansing composition for pest repellent and a cleansing composition for pest repellent are provided. The method of preparing pest repellant comprises providing plants, collecting parts of the plants, obtaining an extract from the parts of the plants, and applying the extract to the harvested plants. The method for processing agricultural harvested products comprises providing harvested agricultural products, collecting parts of the harvested agricultural products, obtaining an extract from the parts of the harvested agricultural products and applying the extract to clean the harvested agricultural products.

Abstract: Chemically phosphorylated soy protein products with much improved functional properties and useful in food industries can be prepared through series of steps: (1) isoelectric washing the defatted soy flour, (2) extracting the proteins present in defatted soy flour in an aqueous medium of the extreme pH value below or above the isoelectric point of soy proteins, (3) alkalifying the extract of soy proteins to pH 11-12 by the addition of concentrated alkali in a short time, (4) modifying the extracted soy proteins under alkaline condition and at ambient temperature by the addition of powdered sodium trimetaphosphate as a phosphorylating agent and (5) recovering the phosphorylated soy protein products by isoelectric washing and final spray-drying as a powder.
