Embodiment 1

[0016] Using cassava residue as raw material, prepare 14% cassava residue liquid, sterilize at 115°C for 30min, then add cellulase 150U / g, α-amylase 10U / g and β-amylase 100U / g, and enzymatically hydrolyze at 55°C After 6 hours of action, add 0.6% of ammonium sulfate, 0.5% of potassium dihydrogen phosphate, 0.5% of yeast extract, and 16% of tomato juice to the cassava residue liquid by weight percentage, sterilize at 115°C for 30 minutes, and inoculate Phaffia yeast (Phaffiarhodozyma) three Grade seed liquid, the inoculum amount is 10%, fermented at 25°C for 4 days, biosynthesized astaxanthin, and then crushed Phaffia yeast cells with an ultrasonic cell disruptor, dried at 55°C, vacuum-sealed, and stored at low temperature. Astaxanthin biofeed. The astaxanthin biological feed can be directly eaten by aquatic products, livestock and poultry, and can also be used as a feed additive.

[0017] The main technical indicators of the product are as follows:

Abstract

The invention discloses a preparation method of an astaxanthin biological feed, which comprises the following steps of: dissolving manioc waste and preparing manioc waste liquid, adding cellulase and diastase after high-temperature sterilization for enzymolysis, and then adding ammonium sulphate, monopotassium phosphate, yeast extract and tomato juice to the manioc waste liquid; inoculating third class seed liquid of Phaffiarhodozyma after high-temperature sterilization for fermentation, biosynthesizing astaxanthin to obtain astaxanthin fermentation liquor, then utilizing ultrasonic wave to break Phaffiarhodozyma cell, drying at the temperature of 45 to 60 DEG C, vacuumizing and sealing, storing at low temperature, and obtaining the astaxanthin biological feed. The preparation method has simple technique; and the obtained astaxanthin biological feed has high astaxanthin content and protein content, is easy to be digested and absorbed by animals, does not contain alcohol substance, has good palatability, and does not contain toxic substance, thus improving the immunity of animals for aquatic product and coloring strength of meat, and being a high-quality feed with the function of health protection.

Description

technical field [0001] The invention relates to a method for preparing biological feed, in particular to a method for jointly treating cassava residues with enzyme preparations and microorganisms to produce astaxanthin biological feed with health-care effects. technical background [0002] my country's cassava production area is vast, and it is planted in Hainan, Yunnan, Guangxi, Guangdong, Fujian and other provinces. The annual output of cassava in the country is more than 10 million tons. At present, cassava is mainly used to produce starch, and there is a large amount of cassava residue after production, which is about 300,000 tons in terms of dry matter. The yield of cassava is high and the price is low, while cassava residue is the waste in cassava processing, and the price is very low. The main components of cassava dregs are cellulose, hemicellulose, a small amount of starch and protein. Its nutritional content is low, and its nutritional composition is not complete...
