Analyzing Raw Milk at the Dairy Plant

Quality control of raw milk before further processing is a crucial process in the dairy industry. The milk is thourougly tested for various parameters, such as fat, protein, total solids, ot solids-non-fat.

The analysis results not only influence the payment of the milk producers but also allow for segregation of the incoming raw milk according to its composition and hence intended process and final product. NIR spectroscopy ensures that consumers receive safe, nutritious, and compliant dairy products while optimizing production processes for the dairy companies.

Biodiesel process control

Biodiesel is a renewable fuel composed of fatty acid mono-alkyl esters, which are obtained through the base catalyzed transesterification of vegetable oils or animal fats with a short chain alcohol, such as methanol or ethanol. The quality control of Biodiesel (B100) is very important and several parameters have to be analyzed to fulfill the requirements of ASTM D6751[1] and EN-14214[2]. However, Biodiesel analysis is expensive, time-consuming, and generates residues. The implementation of a BUCHI NIR-Online® process analyzer after the drying step provides full quality control of the end product. Within milli-seconds, several parameters such as Acid value, Ester content, Methanol, Monoglyceride, Total glycerol, Water and many more are continuously, simultaneously, and accurately measured with NIR.

Quality Control from Raw Fish to Fish Meal

Fish meal, a valuable protein source used in animal feed, undergoes rigorous quality control to meet industry standards and regulatory requirements. Therefore, the journey from fish meat to press cake and finally fish meal involves several quality control stages. Starting with the freshness of the raw material then monitoring the process stages such as cooking, pressing, and drying and grading of the final product according to its quality. 

This application note shows how Near-Infrared Spectroscopy (NIR) can be applied along the whole production process of fish meal. From the floating platforms to the factory, NIR increases analyst safety as well as analysis frequency as a non-destructive, multi-parameter method. NIR can assess the quality of the different product stages, from the raw material to the final product, by measuring key components, such as moisture, fat , protein and most importantly TVN. But also ash, chlorides, or acidity can be detemined by NIR.

Monitoring raw material quality in the feed industry

Producing safe and high-quality feed starts with having total control over the raw material. Real-time information about entire raw material (wheat, corn, barley, oat, sorghum, etc.) batches is of critical importance in order to decide upon unloading or rejection of incoming goods and their segregation as well as to optimize the production steps for highest final quality and profit. With the installation of a BUCHI NIR-Online® process analyzer at the raw material intake, grain composition of entire truck-, train- or shiploads are monitored and documented in a fast, simple, and reliable way. Relevant parameters in grains, that can be monitored with NIR, are protein, moisture, crude fiber, ash, fat, starch and gluten.

Monitoring the Mixing Step in the Flour Milling Industry

Real-time quality control of the mixing step in the flour industry is critical in order to ensure a consistent high final product quality as well as to improve the milling performance. During this step, monitoring key parameters such as protein, moisture or ash allows the millers to confidently operate closer to targets and thus, prevent expensive and time-consuming rework, and hence increase profit margins. The installation of a BUCHI NIR-Online® process sensor equipped with NIR and VIS spectrometers and a high resolution CCD camera after the mixer enables to monitor these target parameters and to screen the grain mixture in a fast, simple, and reliable way.

Monitoring the Quality of Soybeans with NIR

Quality monitoring of whole soybeans at the raw material intake has many benefits, for example prevention of out-of-spec material entering the production, quality segregation prior to processing, or authentication of the raw material. Rapid and accurate determination of the composition of whole syobeans is of critical importance to come to the necessary conclusions.

Based on the accurate measurements of moisture, protein, and oil content, soybeans can be stored at different silos or optimally pretreated for the subsequent production steps. By using NIR spectroscopy to measure key parameters, the soybean industry can ensure consistency in product quality, optimize production processes, and avoid potential economic losses due to substandard soybean lots.

Monitoring the Mixing Step in Feed Production with NIR

Real-time control of the mixing step in the feed industry is critical in order to ensure a consistent high final product quality as well as to improve the milling performance. The mixing step involves combining various ingredients, such as grains and seeds to create a balanced and nutritious feed for livestock and poultry. Efficient monitoring during this stage is essential to guarantee the homogeneity and consistency of the final product. Monitoring key parameters such as protein, fat, moisture, and fiber during this step allows feed millers to operate closer to targets and thus, prevent expensive and time-consuming reworks as well as increase profit margins.

Monitoring Pork Fat Rendering with NIR

NIR spectroscopy has emerged as a powerful tool for quality control in the pork fat rendering industry. It can quantify essential quality indicators such as moisture content, free fatty acids, protein, iodine value, or peroxide values.

The implementation of NIR spectroscopy in the pork fat rendering process offers several advantages. Firstly, it significantly reduces the need for time-consuming and costly traditional laboratory methods, promoting real-time analysis and process optimization. Secondly, the non-destructive nature of the technique allows for continuous monitoring without compromising the integrity of the product. As a result, pork fat rendering companies can enhance product consistency, optimize resource utilization, and maintain high-quality standards, leading to improved efficiency and profitability in the industry.

Residual oil content in white flakes

Monitoring residual oil in soybean white flakes after the extraction step of soybean crushing process, is critical for maximizing oil yield. In addition, this ensures optimum quality of the soybean meal. Rapid and accurate determination of residual oil in white flakes is crucial to optimize the operating parameters of the extractor such as temperature, flake/solvent ratio or extraction time. With the installation of a BUCHI NIR-Online® process analyzer after the extractor parameters such as Resudual oil, moisture or hexane have been successfully analyzed with NIR in order to monitor and document the extraction process in a fast, simple, and reliable way.

Melting range determination of semi-crystalline polymers according to EN ISO 3146

According to the official regulation EN ISO 3146, [1] polymers do usually not have a sharp melting point as known for low-molecular substances. Here, we demonstrate the feasibility to employ the M-565 for the melting range determination of semi-crystalline polymers by capillary tube method according to EN ISO 3146 (method A). Semi-crystalline poly(tetrafluoroethylene) (PTFE) was chosen as test compound for the melting range measurements. For the analyzed PTFE samples we report a narrow melting range between 322.9 ± 0.4 °C and 326.0 ± 0.1 °C. With the M-565 the melting process can be measured and recorded without modification of the instrument.

Refined bleached deodorized oil control

Real-time knowledge about refined bleached deodorized (RBD) oil quality is of critical importance to optimize process conditions to ensure high quality edible oil as a final product. With the installation of a BUCHI NIR-Online® process analyzer after the deodorization step, the quality of RBD oil is standardized, monitored, and documented in a fast, simple, and reliable way. Within milli-seconds, several parameters, such as free fatty acids, phosphorus, moisture, iodine value, peroxide value, soap, and color are continuously, simultaneously, and accurately measured with NIR.
