Description

Orange-flavored Australia freshwater lobster breeding feed and processing technology thereof
Technical Field
The invention belongs to the technical field of shrimp culture feeds, and particularly relates to an orange-flavored Australia freshwater lobster culture feed and a processing technology thereof.
Background
The Cherax quadricarinatus of Australia freshwater lobster is named as four-ridge smooth-shell Nanocao shrimp, has fresh, tender and crisp meat, delicious, fragrant and sweet taste, unique flavor and more abundant nutrition, and is one of the most famous and precious freshwater economic shrimps in the world at present. The body weight of the Australia freshwater lobster is 200g for 100 plus, and the maximum body weight reaches 500 g. The shrimp is fed with animal feed, artificial mixed feed and humus. The shrimp has strong adaptability, can endure severe weather environment, can normally live at the water temperature of 5-35 deg.C, and has strong vitality resistance. The shrimp has advantages of rapid growth, high yield, and easy growth.
At present, China has started to import a large amount of fresh shrimps, and individual places have started to try to breed, and the shrimps are released for breeding in 4-5 months and harvested in 10-11 months every year, so that the yield of the fresh shrimps per mu can reach more than 200 kg. In order to further break through the Australian crayfish breeding industry technology, research and customs must be conducted on multiple levels such as germplasm introduction, fry breeding, feed and feeding, breeding technology, breeding equipment and the like on the basis of the existing test breeding, scientific, advanced and efficient technical means are adopted, a systematic and efficient artificial Australian crayfish breeding mode is gradually constructed, and necessary scientific basis and practical experience are provided for the development of subsequent breeding work. In aquaculture, the feed accounts for about 50-70% of the total aquaculture cost. The nutrition and the quality of the feed not only affect the reproduction and the growth performance of the cultured objects, but also affect the immunity, the disease resistance and the safe environment of the cultured objects, are important factors affecting the product quality (nutrition, appearance and flavor) of the cultured objects, and are only inferior to the influence of germplasm on the product quality. Therefore, research and development of feeds from the aspects of healthy growth, high-quality and safe product production and ecological environment protection of the Australia crayfish are very important for implementing healthy, efficient and environment-friendly production of the Australia crayfish and providing safe and high-quality products.
For years, the citrus planting industry in China develops quickly, not only are strains and varieties eliminated, but also a batch of defective products (including defective products and immature products) and processed leftovers are inevitable after picking, and the defective products and the immature products are good feed sources for aquaculture. According to the analytical test, the citrus contains carotenes: 890. mu.g/100 g, vitamin A: 148 μ g/100g, vitamin B1: 0.08mg/100g, vitamin B2: 0.04mg/100g, vitamin C: 28mg/100g, nicotinic acid: 0.4mg/100g, dietary fiber: 0.4g/100 g; orange contains carotinol: 160 μ g/100g, vitamin a: 27 μ g/100g, vitamin Bl: 0.05mg/100g, vitamin B2: 0.04mg/100g, vitamin C: 33mg/100g, nicotinic acid: 0.3mg/100g, dietary fiber: 0.6g/100 g; the orange contains carotinol: 600 μ g/l00g, vitamin a: 100 μ g/100g, vitamin Bl: 0.05mg/100g, vitamin B2: 0.02mg/100g, vitamin C: 11mg/100g, nicotinic acid: 0.3mg/100g, dietary fiber: 0.4g/100 g.
Disclosure of Invention
The invention aims to provide a processing technology of the orange flavor Australia crayfish breeding feed, which expands the sources of the Australia crayfish breeding feed, can reduce the cost and protect the ecological environment, the prepared breeding feed has a good food calling effect, the quality and the taste of the Australia crayfish can be improved, and a brand-new orange delicate fragrance type Australia crayfish product is obtained.
The technical scheme adopted by the invention for realizing the purpose is as follows:
a processing technology of a feed for culturing Australian freshwater lobsters with citrus flavor comprises the steps of mixing a raw material of orange and the feed mixture, extruding, forming, drying, flattening, uniformly wetting, expanding, coating, drying, cooling and packaging to form the feed for culturing the Australian freshwater lobsters with the citrus flavor; wherein the content of the first and second substances,
the orange and tangerine raw material is selected from tangerine, orange or defective tangerine, pericarp or residue;
the feed mixture contains fermented soybean meal, fish meal, wheat flour, soybean phospholipids and fish oil;
the coating material comprises mineral mixture and vitamin mixture.
The breeding feed obtained by the processing technology is used for breeding Australia freshwater lobsters, and a brand-new orange-flavored Australia freshwater lobster product is developed, so that people can smell a bouquet of orange fragrance, taste and overflow and have no any peculiar fishy smell in the eating process, and the feed has the advantages of full utilization of the existing resources, good food calling effect, capability of reducing cost, protecting ecological environment and the like.
Preferably, the citrus fruit material is selected from the group consisting of defective citrus fruit, pericarp and residue left from processing fruit juice.
Preferably, the citrus raw material must be sorted, cleaned of impurities and musty and rotten products, and kept fresh. Citrus fruits are an important source of vitamins, minerals, dietary fibers and phytochemicals. Vitamins are low molecular compounds essential for maintaining normal physiological functions of the Australian crayfish and are trace elements essential for maintaining the Australian freshwater life. Vitamins participate in the metabolic process, are indispensable micronutrients for growth, development, reproduction and disease resistance, and lack of the micronutrients can cause growth retardation, weakened disease resistance and even death. Each vitamin plays a special nutritional physiological role which cannot be replaced by other substances. Researches show that the addition of defective citrus fruits, pericarp and residues generated during juice processing in the feed can not only improve the taste and flavor of the Australia crayfish, but also increase the appetite of the Australia crayfish, promote the growth and development of the Australia crayfish, maintain the health of the organism, increase the immunity of the organism and reduce the risk of diseases.

In the microbial fermentation process, the contents of crude fat, crude protein, amino acid and phosphorus in the bean pulp can be improved, and macromolecular protein is decomposed into micromolecular protein and active peptide, so that the protein digestion utilization rate and the body immunity of the Australia crayfish are improved, meanwhile, most anti-nutritional factors in the bean pulp are eliminated, the antibacterial capacity of bioactive factors in the bean pulp is improved, and the palatability of the bean pulp is improved. Some enzymes, such as amylase, protease and lipase, are produced in the intestinal tract of the host to enhance the digestibility of host organic substances and proteins, and some essential growth factors, vitamins or amino acids can be provided to influence the energy metabolism and energy balance of the body. Therefore, the fermented soybean meal can improve the feeding rate, the utilization rate and the body immunity of the Australia crayfish.
