Using Calibrations Developed for Fine Milled Meat and Bone Meal on Spectra Measured on Non-Milled Samples

Abstract

all rights reserved animal by-product meal, such as meat and bone meal (MBM), are one of the most valuable protein resources for the compound feed industry. the lifting of some bans concerning the use of MBM in livestock production feeds 1-3 would help feed compound manufacturers to bear the increase in the price of high protein oil meal seeds, caused, in part, by the increase in the market demand for biodiesel production. However, the MBM bans will not be lifted until governments and legislative authorities can be assured that the use of MBM in the food chain is without risk. therefore, the rendering industry and its main customers, pet food industries, have a great concern for the implementation of new analytical methods that ensure traceability, safety and customer demands, allowing a more informative label. Meat and bone meal (MBM) is the dried and rendered product from mammalian tissues and contains bones, viscera, lean tissue and fat. Because of the heterogeneous nature of sources of MBM and the variation in rendering procedures, the chemical composition of MBM may vary widely. representative sampling for chemical and in vivo evaluation of MBM is crucial. 4 nIr technology is now already implemented in many rendering and pet food industries around the world

Long-Length Fiber Optic Near-Infrared (NIR) Spectroscopy Probes for On-Line Quality Control of Processed Land Animal Proteins

“…De la Haba et al., 22 using the same set of samples that were used in the present study with an identical particle size and using a Foss NIRSystems 6500 instrument, albeit with different calibration and validation sets, obtained RPD values for the CP and ASH parameters of 5.05 and 4.08, respectively. It is noticeable that these values are higher than those obtained with the Matrix-F in its two modes of analysis, for the static mode (RPD CP = 2.74; RPD ASH =1.80) and for the dynamic mode (RPD CP = 2.90; RPD ASH = 1.86).…”

It is noticeable that these values are higher Esbensen et al 52 note that the value of RPD is dependent on the type of sample being used, as well as on its prior preparation, its presentation to the instrument, the error in the reference method, and generally on the values of the set of samples used.…”

“…The available near-infrared (NIR) spectroscopy scientific literature concerning the analysis of PAPs has shown that it is possible to specify the chemical characteristics of these protein sources for animal feed, 10–17 and also to detect and quantify the species composition in a particular sample of feed or meal. 18–25…”

“…9 The available near-infrared (NIR) spectroscopy scientific literature concerning the analysis of PAPs has shown that it is possible to specify the chemical characteristics of these protein sources for animal feed, [10][11][12][13][14][15][16][17] and also to detect and quantify the species composition in a particular sample of feed or meal. [18][19][20][21][22][23][24][25] The research that has been published on animal-derived protein feeds has largely been conducted using monochromators and milled samples, and has encouraged the most innovative rendering companies, once they engage with the ''analytical, rapid and low-cost control culture,'' to incorporate NIR spectroscopy technology for ''at-line'' use in the quality control of their end-product. Leading companies in the pet food market have set up quality control systems based on NIR spectroscopy technology to ensure that the raw materials provided by their suppliers meet their quality specifications.…”

Near-Infrared Spectroscopy and Mode Cloning (NIR-MC) for In-Situ Analysis of Crude Protein in Bamboo

“…Field studies require a simplified procedure for minimal or unprocessed fresh samples. The calibration transfer of a master prediction model generated for fine-ground samples may be applicable to nonground or even wet samples [19]. However, in some cases, the model cannot be applied directly to new datasets because the gaps between the existing and new types of samples cause variation between the spectra, leading to biased predictions.…”
