Embodiment 1

[0050] In this example, near-infrared spectroscopy was used to detect the content of lysine in the feed additive L-lysine sulfate sample.

[0051] The method for establishing a model based on the rapid detection of lysine content described in this embodiment specifically includes the following steps:

[0052] (1) Sample collection and preparation

[0053] 59 samples of feed additive L-lysine sulfate of known origin were taken, all from enterprises. Each sample is equally divided into two parts, one of which is kept as the original un-grinded sample, and the other is crushed by a cyclone mill and passed through a 60-mesh sieve, which is the pulverized sample; then the above-mentioned un-grinded and The pulverized sample is divided into two parts on average, one of which is kept as an undried sample, and the other is placed in an oven at 105°C for 5 hours for drying, which is the dried sample. The feed additive L-lysine sulfate samples respectively formed samples in four diffe...

Abstract

The invention belongs to the technical field of feed detection, and concretely relates to a method for rapidly detecting the content of lysine in a feed additive L-lysine sulfate based on near infrared spectroscopy. The method for rapidly detecting the content of lysine realizes detection based on the near infrared spectroscopy, and a near infrared spectrum model for detecting lysine is established through a suitable technology, and can rapidly, highly-efficiently and accurately detect the content of lysine in the feed additive L-lysine sulfate. The method using the advantages of short analysis time and simplicity in operation of the near infrared spectroscopy is suitable for analyzing and detecting a large batch of samples; and no chemical reagents are used in the analysis process, so thedetection cost is greatly saved, and the disadvantages of long time, hig hconsumption and high device operating requirements of acid hydrolysis process detection of amino acids in standards Determination of Amino Acids in Feed (GB / T 18246-2000) are obviously improved, thereby the method has the advantages of high efficiency, greenness and environmental protection.

Description

technical field [0001] The invention belongs to the technical field of feed detection, and in particular relates to a rapid [0002] Method for detecting lysine content in feed additive L-lysine sulfate. Background technique [0003] Feed additives refer to small or trace substances added during feed production, processing and use. Although the amount is small, the effect is significant. Feed additives are inevitable raw materials used in the modern feed industry. They have obvious effects on strengthening the nutritional value of basic feed, improving animal production performance, ensuring animal health, saving feed cost, and improving the quality of animal products. [0004] L-lysine is one of the eight essential amino acids that are necessary in humans and animals but cannot be synthesized by themselves. Lack of lysine in humans and animals will cause metabolic disorders in the body and cause certain physiological functional diseases. In animal feeding, it is often nec...
