what! Can Fourier Near Infrared Spectroscopy identify edible fungi?
The infrared spectrum reflects information on the composition, relative content, and molecular structure of the substance, and it can reflect the difference in the substance from the chemical nature. Infrared spectroscopy technology requires less sample, no extraction and separation of samples, and is relatively easy to operate. Since the introduction of this technology in 1950, scholars from Europe and the United States have successively applied infrared spectroscopy to the pathogenic bacteria and colonic microorganisms of animals and humans. The research on identification has made great progress. With the development of infrared spectroscopy and stoichiometry, infrared spectroscopy has been widely used in the identification of tumors and Chinese medicinal materials in recent years. Wang Hong [1] studied the Fourier transform of Ganoderma lucidum, Pleurotus ostreatus and four strains of shiitake mushrooms. Infrared spectroscopy, the experimental results show that the three edible fungi have their own characteristic FTIR spectra, which can be identified by Fourier transform infrared spectroscopy.
Fully automatic injection Fourier transform near-infrared analyzer
The InfraLUM® FT-12 and InfraLUM® FT-40 (for grain only) type Fourier near-infrared spectroscopy (see Figure 1), which is represented by Shanghai Ruiqi, is the most cost-effective instrument for quality and quality control and can be quickly detected. The active ingredients in edible fungi have their own calibration software, and they can establish their own calibration models. In addition, the 12 types of instruments detect many types of samples (feed, grain, oil, food, agricultural products), while type 40 It is a model developed by our company for the analysis of grain; the quality index is rich (water, crude protein, crude fiber, coarse ash, amino acid, crude fat, etc.); a large number of localization is the stereotype calibration model; the open calibration model has Advanced calibration software, users can develop and expand the model by themselves; the network is powerful, can realize unified management of calibration model; easy to operate, high-precision detection of required indicators within 1.5 min; fast complete analysis, no sample required The advantages of preparation (grinding and grinding) and the like.
In summary, our company's InfraLUM® FT -12 and InfraLUM® FT-40 FT-IR spectra are indispensable for research institutions and food safety monitoring.

Amino acid plays an important role in human and animal nutrition and health. It has wide use and prospect market. we are decided to develop an amino acid derivative compounds according to the company 's own personnel expertise . Currently we focus on the development of amino acid derivatives. Amino acid derivative is a compound derived from sequence of reactions by amino acid, the predecessor of the amino acid derivative is an amino acid. Under leading by Massachusetts Institute of Technology Dr. Wanghong Yao , synthesis tenology has continuous improvement, production process has continuous innovation. Our original synthesis method is on the transferring to the fermentation method , enzymatic method. Under strictly environmental pressure background, the method not only greatly reduce the pressure but also improve economic efficiency. Some of our products can reach production capacity in tons, we will take reasonable measures to try to meet the market demand , and strive to achieve on time delivery , delivery asap in timely period .
we will give you:
1. Best quality in your requirement
2. Competitive price in China market
3. Mature Technical support
4. Professional logistic support
All we want is win-win business. Send yr. inquiries, you will get it!
