Description
Technical Field
The invention belongs to pet waste cleaning products, relates to a method for preparing natural indication cat litter by anthocyanin plant extraction waste, and belongs to the technical field of cat litter preparation.
Background
Cats have the habit of using sand to cover their excretions. Cat litter is the object used by the owner of the litter to bury fecal and urine in the cats and when a trained cat needs to drain, the cat litter will travel into the litter box and over it. When the animal's excrements or urine comes into contact with it, the litter forms an integrated ball with the excrements or urine due to the hygroscopicity of the litter, and the litter that is not contaminated with excrements or urine is not contaminated. The cat litter types sold on the market at present can be divided into two major types, namely organic cat litter and inorganic cat litter. The inorganic cat litter mainly comprises bentonite cat litter and crystal cat litter. The bentonite cat litter is low in cost, and has the defects of high dust and poor adsorption capacity, and the cat litter is susceptible to respiratory diseases after being used for a long time. The crystal cat litter is made of transparent silica gel, has beautiful pattern and good water absorption, but is difficult to degrade, has secondary pollution after being discarded, and has very high cost. Organic cat litter is further classified into wood-chip cat litter, paper-chip cat litter, and bean curd refuse cat litter. The wood chip cat litter has strong water absorption capacity, but pine wood tastes unlike cats and has a common agglomeration effect; the paper-scrap cat litter can be poured into a closestool to be flushed away, but has weak coagulation capacity and is easy to turn into paste when meeting urine; the bean curd residue cat litter is good in agglomeration effect, can be flushed into a closestool, but cannot be cleaned in time, and can be rancid.
Catnip is a mild tranquilizer for cats, and the addition of a small amount of catnip in cat litter is beneficial to reducing the rejection of cats to cat litter, attracting cats to cat litter for excretion, and is beneficial to the health of cats, and can relieve the anxiety and other bad emotions of cats, so that cats feel relaxed and cool. And secondly, the cat food also has the effects of increasing the exercise amount of the cat, promoting the digestion of the cat, relieving flatulence, stomachache and the like.
At present, the research on plant cat litter at home and abroad mainly focuses on preparing cat litter from plant materials such as corn straws, sunflower straws and Chinese herbal medicines, and mostly focuses on caking property, deodorization and bacteriostasis performance, such as a sunflower composite pure plant pollution-free cat litter and a production method thereof (application number: 201810650581.1), a natural Chinese herbal medicine plant cat litter (application number: 201710880506. X), a corn cob plant cat litter and a preparation method thereof (application number: 201810999057.5). The pH indicating cat litter at home and abroad is realized by adding a pH indicating material, and the pH indicating material and the pH indicating cat litter for the cat urine in Chinese patent and the preparation method thereof (application number: 201910841624.9) are composed of the pH indicating material such as methyl red, bromothymol blue and the like and basic bean curd cat litter. However, at present, no report is found on the research of cat litter using anthocyanin-containing plant extraction waste as a natural pH indicator at home and abroad.
Anthocyanins are also called anthocyanins, and are widely present in plants, and fruits, vegetables, flowers and grains contain abundant anthocyanins, such as purple sweet potato, black potato, purple cabbage, black bean, black rice, roselle, etc. The anthocyanin substance changes color along with the change of pH value, is an excellent natural pH indicator, is dark purple red when the pH value is 3, is light purple blue when the pH value is 6, and has obvious color change. Generally, the pH value range of urine of a cat is between 5.5 and 7.5 under normal conditions, the urine with higher pH value is easy to cause the formation of magnesium crystals, and the health condition of the cat can be predicted by indirectly detecting the pH value of the urine of the cat through the color change of the cat litter.
The plant residue after the anthocyanin is extracted is still rich in cellulose, pectin, starch and other substances, and the cat litter is produced by utilizing the anthocyanin plant extraction waste after the anthocyanin is extracted, so that a coloring agent is not required to be added, and waste is changed into valuable; the characteristic that anthocyanin shows different colors under different pH conditions is used as a natural indicator, so that a breeder can conveniently eradicate polluted cat litter in time, and the health condition of the cat is indirectly reflected through the color change of the cat litter, so that the breeder can predict the disease of the cat in an early stage.
