F-751 Series vs Sunforest: Predictive Power vs Processing Convenience

December 3, 2025 at 12:16 am | Updated December 3, 2025 at 12:16 am | 12 min read

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…

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…

What Is Dry Matter Content and Why It’s Crucial for Fresh Produce Quality?

Dry matter is measured on farms to monitor maturity and determine the optimal harvest time for climacteric fruits and vegetables. In the postharvest stage, dry matter is used for quality control for sorting and grading fresh produce. Dry matter determines the storage, transport, and ripening conditions to achieve optimum quality and extended shelf life. Wholesalers,… Continue reading…

What Are the Best Melon Harvest Maturity Indices?

The harvest maturity indices vary based on the melon groups. The physical harvest maturity indices are size, shape, weight, color, firmness, stem detachment, and tendril condition. The chemical harvest maturity indices include Brix/sweetness, titrable acidity, taste, and aroma. The optimal harvest maturity index for melon differs for each accession. Several aspects of the ripening process must… Continue reading…

Advances in Near-Infrared Spectroscopy for Root Crop Quality Detection

Near-infrared (NIR) spectroscopy is an interesting technology because it can detect quality nondestructively, rapidly, and precisely. NIR spectroscopy can correctly estimate internal quality parameters like protein, sugar, water content, starch, and anthocyanins. NIR spectroscopy helps in the early detection of potato diseases and their severity. NIR spectroscopy for root crops has been applied in laboratories,… Continue reading…

What Is the Best Blackberry Harvest Maturity Index for Quality?

Color is the chief harvest maturity index. Other appearance parameters, such as firmness, size, and weight, are also used. Chemical harvest maturity indices, especially the latter, are crucial, including total soluble solids (sugar content), titrable acidity, and taste. Blackberries for processing require different harvest maturity indices and increasingly use dry matter. Harvest maturity indices are… Continue reading…

How Does Bruise Susceptibility in Fresh Produce Impact Quality and Harvest Timing?

Bruise susceptibility varies based on the species, cultivar, and physical and physiological properties of fresh produce. The critical bruising threshold estimates the bruise susceptibility of fruits at different firmness. A critical bruising threshold has been used to develop a harvest maturity index that identifies the minimum firmness (or maximum maturity) for harvesting stone fruits. Bruising… Continue reading…
