Near-infrared (NIR) spectroscopy is an already widely used technique in the food industry for quantitative analysis of nutritional and quality parameters. Chemometric techniques, such as partial least squares (PLS), used in conjunction with NIR spectroscopy offers an alternative rapid and non-destructive method to the wet chemistry reference methods for the analysis of crude palm oil (CPO), with multiple property values being determined simultaneously.
During the frying process, palm oil undergoes a series of degradation reactions, caused by heat, water and air, which results in oxidation of the oil and can ultimately reduce the quality of the oil and cause adverse health effects for consumers. The extent of oxidation in the oil can be assessed by determining the peroxide value (PV). Generally, the lower the PV, the higher the quality of the oil but very rancid oils, with high levels of oxidation, may have a reduced PV due to peroxides decomposing to form aldehydes and other secondary oxidation products. The acid value (AV) measures how many fatty acids have been cleaved from their parent molecule due to hydrolysis, which may result from the oxidation of the peroxides.

Avocado oil, a high-value product, may be adulterated with lower-value oils in order to increase profit margins. These adulterant oils may include nut-containing oils which may induce a dangerous allergic reaction for consumers with nut allergies. This works shows how near-infrared spectroscopy with a HTM accessory can provide accurate detection and identification of adulterant oils in avocado oil. Tthe Adulterant Screen algorithm rapidly identifieds the adulterant present and provides a relatively accurate estimate of the adulterant concentration.
Common adulterants found in Manuka honey include beet, corn and rice syrups. The differing photosynthetic pathways in the plants used to produce these adulterants generally means that different techniques are required to detect them. Mid-Infrared spectroscopy with Adulterant Screen™ technology, can provide rapid detection of all three adulterants without the need for solvents or time-consuming sample preparation
There is considerable scope for rapid on-site analysis of foods by using the combination of IR spectrometers with Principal Components Analysis (PCA) to classify complex materials. This application note shows that Near-IR spectroscopy is more suitable than Mid-IR for the analysis of herbs and spices and could also be applied to other inhomogeneous foods.The longer effective pathlength and better spatial averaging available with Near-IR diffuse reflectance is beneficial for adulterant detection, and using glass sample containers allows for rapid analysis with no accessory cleaning required. Larger sampling areas and the ability to spin the material during Near-IR analysis results in more reproducible and representative sampling of food products with an inhomogeneous nature.
For processors as well as users of blood meal it is essential to be able to test samples for nutritional composition and rapid analysis of parameters such as moisture, oil and protein are of great benefit. The Near Infrared Reflectance (NIR) technique is particularly suited for measurement of these types of samples.

Moisture, starch, protein and fat are important parameters to consider when assessing the quality of corn. The specialty end uses for corn often require these parameters to fall within a certain range. More worryingly, particularly high or low concentrations of these parameters could lead to health or economic issues.This work shows accurate determination of multiple parameters of ground corn samples obtained with the FT 9700 NIR.
Harvested wheat is typically milled into flour which can then be used tomake a wide range of foods, such as bread and pasta or used as rawmaterial in feed production. Moisture and protein are key parameters for evaluating quality of a wheat sample to be used in flour milling or for setting up formulation in feed milling. This application note shows The results show that the FT 9700 NIR analyzer can accurately determine both the moisture and protein content in ground wheat samples.
Major nutritional components of soymeal, such as moisture, protein, and fat, can have a key influence on the animals' growth and, ultimately, the overall profits of farmers. Therefore, accurate analysis of these nutritional parameters of soymeal is highly important to allow producers to ensure that they are meeting the end-users specific needs. Near-infrared (NIR) spectroscopy, on the other hand, can rapidly quantify these parameters without the need for solvents or lengthy sample preparation. When combined with chemometric techniques, such as partial least squares (PLS), NIR spectroscopy can provide a fast and accurate method to quantifying these key nutritional parameters in soymeal at any stage of the production process.

The value of milk powder is linked to its protein content, and standard methods for protein analysis rely on a simple nitrogen assay, with the protein concentration inferred from the nitrogen content. Consequently, the addition of chemicals rich in nitrogen can artificially increase the apparent protein and thus the price demanded. NIR spectroscopy clearly has a role to play, given its ubiquity in raw materials testing. The unique Adulterant Screen algorithm from PerkinElmer retains the strengths of non-targeted chemometric methods like SIMCA, but obtains greater sensitivity by utilizing a library of spectra of potential adulterants. The method can be easily adapted to screen new products or for new adulterants, without having to prepare mixture samples for calibration.
This work shows an on-site, rapid and low-cost technique for the accurate measurement of flower potency. FT-NIR spectroscopy provides rich information regarding the chemical composition of cannabis flower. When combined with chemometrics, the FT-NIR offers unparalleled speed and simplicity that cannot be matched by traditional techniques. PerkinElmer Spectrum Two NIR with the Near Infrared Reflectance Module (NIRM) is used to quantify total THC and total CBD in dried cannabis flower. The use of FT-NIR directly at the grow site would reduce overall research and development costs for cultivators.
