  • Evaluating 7 Crops with 1 Tool

    Evaluating 7 Crops with 1 Tool

    Alberto De Marcos and his team at Semillas FitĂł are exploring the use of NIRS to breed better varieties of seven solanaceae (nightshade) and cucurbit (gourd) crops: tomato, pepper, eggplant, melon, watermelon, zucchini, and cucumber. In our most recent interview, Application Scientist Galen George sits down with Alberto to chat about his plans to integrate the Felix InstrumentÂŽsF-750 Produce Quality Meter to improve in-house testing with data-driven insights.

  • Detecting fungal disease in the fresh produce supply chain

    Detecting fungal disease in the fresh produce supply chain

    Ethylene produced by many fungi can cause disease in perishable fresh produce. Scientists found that this phytohormone can be used as a marker in non-destructive diagnosis for fruit disease detection of post-harvest fruits. A portable gas analyzer was used in an experiment to measure fungal ethylene in real-time. The findings from the experiment could help in reducing food loss. Read more

  • Vis-NIR spectroscopy for mandarins

    Vis-NIR spectroscopy for mandarins

    Mandarin is among the fruits for which the application of VIS-NIR spectroscopy techniques has been widely tested by scientists. It has been proven to be suitable to assess dry matter, total soluble solids, titrable acidity, and firmness with great accuracy. There are many applications for this internal data to determine the maturity, health, and quality parameters of mandarins, providing benefit to stakeholders at all levels of the supply chain.

  • NIR for grapes, to detect a wide range of chemicals in an easy way

    NIR for grapes, to detect a wide range of chemicals in an easy way

    Many chemical components in grapes are monitored. Besides the usual total soluble solids (TSS) and titratable acidity (TA) that are measured in all fruits, chemicals that give flavor are also measured. These include anthocyanin, total polyphenols, and many minerals. Traditionally, grape samples were collected and transported to laboratories for analysis. These methods were time-consuming, expensive, and involved the use of chemicals. Portable devices that have miniaturized near-infrared (NIR) spectroscopy are now allowing analysis to be conducted onsite from the vineyards to processing… Read more

  • Advantages of NIR spectroscopy to determine plum quality

    Advantages of NIR spectroscopy to determine plum quality

    Spectroscopy is the technique of studying chemicals based on their interaction with light. The interaction can be absorption, reflectance, or transmission of light. The data is generated as a spectrum. Near-infrared is the range between 750-2500 nanometers (nm) and is next to visible red light. This spectrum is suitable for finding the composition of a compound, as it reacts with the C-H, O-H, and N-H bonds. Thus, NIR spectroscopy is useful in qualitative and quantitative analysis of bio compounds. Being non-destructive, NIR spectroscopy can be repeated as many times as needed on a… Read more

  • A hand‐held spectrophotometer for in‐field phenotyping of tomato and pepper

    A hand‐held spectrophotometer for in‐field phenotyping of tomato and pepper

    Scientists tested the viability of the portable and non-destructive F-750 from Felix Instruments - Applied Food Science as a phenotypic tool for tomato (Solanum lycopersicum L.) and pepper (Capsicum annuum). They were able to recommend it based on their findings along with some suggestions. They tested fruit quality traits such as soluble solids, pH, and carotenoids in elite cultivars and introgression lines of tomato, as well as diverse hybrid and open‐pollinated varieties of pepper. The F-750 was found to be suitable for quality trait modeling, but there are limitations, so only… Read more

  • In-line VIS-NIR Spectroscopy for Produce Sorting

    In-line VIS-NIR Spectroscopy for Produce Sorting

    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. Most fruits and vegetables today are still sorted mostly on the basis of external features such as color, size, weight, and blemishes, but consistently meeting quality control demands is possible only when internal parameters are also examined. Light is made up of wavelengths. The visible range that the human eye can see (VIS; 400–700 nm) is… Read more

  • Wounding and UVB Light Synergistically Induce the Biosynthesis of Phenolic Compounds and Ascorbic Acid in Red Prickly Pears (Opuntia ficus-indica cv. Rojo Vigor)

    Wounding and UVB Light Synergistically Induce the Biosynthesis of Phenolic Compounds and Ascorbic Acid in Red Prickly Pears (Opuntia ficus-indica cv. Rojo Vigor)

    Nair et. al 2019, sought to test increases in the production of desirable nutraceuticals in opuntia fruits by using wounding and ultraviolet B (UVB) radiation for 15 minutes, separately and in combination. Fruits treated with UVB showed increases of between 186.2-709.8% of phenolic compounds such as quercetin, sinapic acid, kaempferol, rosmarinic acid, and sinapoyl malate in the peel and pulp, as a result of an increase in the phenylalanine ammonia-lyase (PAL) activity. While an increase in l-galactono-Îł-lactone dehydrogenase (GalLDH) activity led to more ascorbic acid biosynthesis due… Read more

  • NIR, a non destructive tool for the frequent analyses necessary to monitor quality and setting harvest dates in a wide variety of cherries

    NIR, a non destructive tool for the frequent analyses necessary to monitor quality and setting harvest dates in a wide variety of cherries

    Visual to near-infrared spectroscopy (Vis-NIR) is widely used in the supply chain to optimize the production of fruits. The application of this versatile technique is being tested and tried for an increasing number of fresh produce. Recent research shows which internal parameters in cherries can be estimated non-destructively by NIR spectroscopy. Based on their findings, scientists recommend the use of handheld devices with NIR spectroscopy for the frequent analyses necessary to monitor quality and setting harvest dates in a wide variety of cherries. NIR Spectroscopy NIR spectroscopy is… Read more

  • NIR for nectarines and peaches

    NIR for nectarines and peaches

    Quality parameters are useful in various stages of a supply chain and are used for different purposes. In peaches and nectarines, the quality parameters have been used to estimate maturity, select fruits for processing, and monitor quality. Near Infra-red (NIR) spectroscopy can be used for the non-destructive, rapid, and cost-effective chemical analysis of the internal attributes. The application of this technology for these fruits has just begun, so we provide a brief overview below. Peaches and Nectarines are Different Fruits Though the two fruits, peaches and nectarines, are similar in… Read more
