Portable devices based on near-infrared and visible light spectroscopy have revolutionized grape analysis in the vineyard, supply chain, and the processing of grape products. These new tools can be used to gather rapid and precise information on the chemical composition, nutritional value, and physiology of grapes. In this article, we provide a brief overview of… Continue reading…

Due to its health benefits, olive oil’s global popularity has grown substantially in recent years, making the olive one of the most extensively grown crops in the world. Since there are different grades of olive oil produced, it is necessary to be able to optimize for both oil quantity and quality. The color index method… Continue reading…

Due to the rising preference for organic food, it is becoming necessary to replace chemical coating on fruits with natural alternatives. Recent studies from South Africa have found a potential replacement for avocados, which could substantially reduce postharvest losses. A small handheld ethylene measuring device played a key role in this exciting new research. Avocado… Continue reading…

Consumers expect that the fruits and vegetables they buy are of the highest quality. Therefore, more in-depth quality control and sorting systems are increasingly being used to ensure that supplies reaching retailers meet the required standards. Many fruits and vegetables today are still sorted mostly on the basis of external features such as color, size,… Continue reading…

Ethylene (C2H4), a hormone produced in the roots and shoots of a plant, is responsible for the ripening processes in climacteric fruits, germination of seeds, elongation of the stem, and senescence of leaves. Depending on the species, ethylene can also encourage or inhibit flowering, pollen and ovule development, flower opening, and senescence. Moreover, ethylene can… Continue reading…
