Appetite Attractants in Pet Food

Chicken liver is a cost-effective functional raw material in pet food (cat food/dog food), which can not only improve palatability but also provide key nutrients. The following are its systematic application strategies and technical points:

01 Core value nutritional advantages of chicken liver High protein and low fat: crude protein ≥60% (dry basis), fat ≤15%, better than most animal offal. Vitamin treasure trove: Vitamin A (retinol) content reaches 14,000-25,000 IU/100g, meeting more than 300% of the daily needs of cats and dogs; rich in B12 (hematopoiesis) and iron (high bioavailability). Natural attractant ingredients: Contains nucleotides (IMP/GMP), free amino acids (glutamic acid, glycine) and other umami substances. Economical The price is only 1/3-1/2 of beef liver (domestic chicken liver powder is about 40-60 yuan/kg, fresh liver is 8-12 yuan/kg). High utilization rate of slaughter by-products and stable supply chain.

02Key processing technology Low temperature drying (below 60℃): retain vitamin activity (such as heat-sensitive vitamin A). Ultrafine grinding (particle size ≤ 80 mesh): improve uniform dispersion in dry food and avoid agglomeration. Antioxidant treatment: add 0.01% rosemary extract to prevent fat oxidation (chicken liver contains 4-6% fat).

03Application scheme Dry food: add 3-5% chicken liver powder (replace 1/3 meat powder), and the palatability is improved by 50%+. Wet food: use 10-15% fresh chicken liver (compounded with chicken), and add 0.1% taurine (part of the chicken liver will be lost during processing). Freeze-dried snacks: pure chicken liver freeze-dried blocks (slice thickness 2-3mm, -40℃ vacuum drying). 1. Dog food (auxiliary addition) Economic dog food: 2-3% chicken liver powder + yeast extract compound use. Functional food: enzymatic chicken liver pulp (0.5-1%) is used for elderly dog food (to promote appetite).

Through reasonable application, chicken liver can not only reduce the cost of pet food (compared with pure muscle ingredients), but also significantly improve product competitiveness. The key lies in the precise control of the added amount and processing technology.
