Understanding Chemometrics for NIR Spectroscopy

Chemometrics is a multidisciplinary approach referring to the analysis of large, complex chemical data obtained from spectroscopic measurements. Chemometric tools are used in research, quality control, and in food processing. They are useful for a wide variety of professionals such as chemists, technologists, agricultural scientists, microbiologists, engineers, farmers, suppliers, distributors, and retailers. Chemometrics Defined Svente… Continue reading…

Optimizing Long-Term Potato Storage with Ethylene Measurement

Cold storage facilities aiming to reduce ethylene production and respiration rates in potatoes require considerable power consumption for cooling and ventilation. Lowering power consumption has become a major goal to bring down the costs of storage. A group of scientists who were developing the optimum method of ventilation had to monitor gas exchanges in an… Continue reading…

Miniaturized and combined with other modern technology, these devices now have a wide range of research and practical applications in food, medical, industrial, and environmental fields. This article focuses on the reasons for the popularity of spectrophotometry techniques. Principle of Spectrophotometry Light… Continue reading…

Gas Analysis for Humane Poultry Euthanasia

On-farm euthanasia is sometimes necessary. The method for this type of euthanasia must be efficient and easy, as it is performed by a single operator. The procedure must also be humane and, in many places, it must meet stringent governmental standards. It must also meet the demands of consumers, and be sensitive to the conditions… Continue reading…

Pears and Pruning: Non-Destructive Dry Matter Measurement in Pears

Dry matter has been gaining popularity as a quality metric in fruit production to fix harvest time and predict postharvest quality and taste. There is a renewal of research in many fruits to optimize fruit quality and yield using this new metric. Though these developments, themselves, are exciting, new technologies to measure dry matter are… Continue reading…

Assessing Antioxidant Content in Tomatoes with NIR Spectroscopy

Tomatoes are laden with many healthy phytochemicals, including antioxidants, that make them a valuable food commodity. Measuring changes in the levels of phytochemicals during maturity leading to harvest and postharvest is crucial to producing nutritious tomatoes. To analyze antioxidants in the supply chain, scientists tested the effectiveness of near-infrared spectrometers to replace accurate yet laborious… Continue reading…

Measuring Gas Exchange in Biosynthesis of Phytochemicals

Scientists are constantly searching for reliable and affordable sources of medicines. It is well known that many plants have medicinal value and trace amounts of the phytochemicals of interest. However, the production of medicines from these plants requires that harvesting and extraction be in amounts that allow the process to remain sustainable. One study that… Continue reading…
