How to Evaluate Data Accuracy in NIR Meters
NIR meter data accuracy is the first thing experienced users look at when deciding whether a handheld instrument is useful or just another gadget. Near infrared spectroscopy is not new, but applying it reliably in the field is still challenging. Differences in optics, calibration models, sampling methods, and validation practices can easily lead to inconsistent… Continue reading…
Investing in a Research-Grade vs Commercial-Use Quality Meter
Choosing the right produce quality meter is a decision that affects data quality, operational efficiency, and long-term return on investment. Whether you are running field trials, managing postharvest storage, or making rapid commercial decisions on fruit maturity, the difference between a research-grade instrument and a commercial-use quality meter matters. At first glance, many quality meters… Continue reading…
Evaluating Return on Investment for Portable NIR Devices
Evaluating return on investment for portable NIR devices is no longer just a financial exercise. For produce managers, quality teams, and postharvest researchers, it has become a practical question tied directly to daily decisions. Portable NIR devices ROI depends on how effectively these tools replace slow, destructive, or subjective quality assessments with fast, repeatable data.… Continue reading…
Using Felix NIR Devices for Research on Fruit Maturity Index Correlations
Research into fruit maturity index correlations has moved quickly over the last decade, largely because non-destructive tools now allow researchers to collect large datasets directly from intact fruit. The term fruit maturity index is no longer limited to lab-only measurements or destructive sampling protocols. With handheld near-infrared technology, researchers can link internal quality attributes to… Continue reading…
How Did Tech Improve Postharvest Fresh Produce Quality in 2025?
Novel technologies, such as air- or oxygen-micro-nano bubble water and ozone, are under focus as safe and environmentally friendly alternatives to chlorine for postharvest disinfection of fresh produce. Research on the application of peptide hormones to preserve postharvest horticultural quality, which began a few years ago, intensified in 2025. Another emerging field is the use… Continue reading…
F-751 Series vs Sunforest: Predictive Power vs Processing Convenience
When teams evaluate handheld NIR tools for fruit maturity assessment, two priorities tend to rise above the rest: predictive power and processing convenience. The Felix Instruments F-751 series focuses on deep, crop-specific predictive models designed to deliver stable internal-quality estimates. Sunforest’s H-100 series emphasizes multi-fruit versatility and general convenience across orchard and supply-chain tasks. Both… Continue reading…
WEBINAR: Half a Million Fruit Quality Scans: What the Data Says About the Future of Freshness
Fruit quality can feel unpredictable, even when teams rely on long-standing testing methods. Over the past decade, Felix Instruments has scanned more than half a million individual fruits across crops such as avocado, mango, citrus, grape, apple, and more, building a large real-world dataset that reveals just how variable internal quality can be. In this… Continue reading…
Why Is the Geographical Origin of Meat Important and How Is It Verified?
Determining the geographic origin of meat is necessary to authenticate the quality and specialty indicators of origin. Geographic origin determination is also necessary to control the entry of banned meat contaminated with animal pathogens and to prevent the spread of disease. Near-infrared spectroscopy is one of the easiest, portable, and accessible methods of meat analysis… Continue reading…
What Are Brix Measurements and Are They Crucial in Fresh Produce?
Brix is the most common unit used in the food and beverage industry. Brix measurement is helpful in crop production, scheduling harvest, quality control, marketing, and processing. The use of Brix is widespread because it is easy and inexpensive, and it can be used in fields, storerooms, during transit, in shops, and in processors. Nondestructive… Continue reading…
Cherry Harvest Time: How to Know the Best Day to Pick Sweet Cherries
Sweet cherries’ harvest maturity can be estimated by chronology and physical attributes like skin color, weight, size, and firmness. Internal quality parameters like soluble solids content, titratable acidity, and taste can also be used as harvest maturity indices. Skin color is considered the best indicator for the optimum harvest maturity of cherries. Simultaneous non-destructive estimation… Continue reading…
