Problems solved by technology

[0003] Although the products invented by the existing patented technology have certain improvements compared with traditional products, there are still shortcomings such as complex production process and organic solvent waste liquid generation.
In addition, the current development of organic trace element products mainly focuses on improving stability and digestion and absorption rate, and less attention is paid to the improvement of palatability. So far, no organic trace element products and patented technology invention
For the livestock and poultry breeding industry, poor palatability is a key factor affecting animal feed intake, and it is also an important obstacle in the marketing of organic trace elements

Abstract

The invention discloses a high-feeding-attraction and high-palatability organic trace element and a preparation method thereof. The preparation method comprises the following steps of: performing primary seed culture, secondary seed expanding culture and aerobic expanding culture on a flavor-producing yeast strain, and culturing for 3-4 hours in an anaerobic environment; continuously dripping a prepared high-concentration inorganic salt metal ion solution into fermentation liquor after anaerobic culture, and chelating for 2-3 hours under an anaerobic condition; heating, and fully autolyzing the flavor-producing yeast strain under a certain condition; and drying the autolyzed flavor-producing yeast strain solution by adopting a film drying method, and processing to prepare an organic trace element product. According to the method provided by the invention, the processes of centrifuging, concentrating, extracting, washing and the like are not needed in the production process, no organic solvent is discharged, the process is relatively simple, the process cost is low, and the method is suitable for large-scale industrial production. In addition, the prepared product solves the problem that the current organic trace element is low in palatability and has wide application prospects and market space.

Description

technical field [0001] The invention relates to the field of organic trace elements, in particular to an organic trace element with high palatability and palatability and a preparation method thereof. Background technique [0002] Trace elements are indispensable nutrients in the normal growth and metabolism of livestock and poultry animals. The trace elements currently in the market are mainly inorganic salt trace elements, organic acid complex trace elements, polysaccharide complex trace elements, and amino acid chelated trace elements And protein chelated trace elements. Among them, inorganic salt trace elements and organic acid trace elements are gradually replaced by organic trace elements due to many defects such as uneven mixing, poor stability, easy deliquescence, easy oxidation, and low absorption and utilization rate. Organic trace elements are complexed or chelated by polysaccharides, amino acids, proteins and metal trace elements, which have high stability and d...
