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…

What Is Titratable Acidity and Why Is It So Important in Fresh Produce?

Titratable acidity (TA) is measured as it is an indicator of quality, maturity, and taste in fresh produce. Measuring titratable acidity in the fresh produce supply chain can ensure quality, shelf-life, consistency, and consumer satisfaction. It is used to determine harvest time, quality control, sorting, grading, and regulatory compliance. Titratable acidity is a crucial intrinsic… 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…

F-750 vs TR Turoni 532: Which Produce Quality Meter Gives You Better Dry Matter Accuracy?

When measuring fruit maturity and postharvest quality, dry matter is one of the most trusted indicators. It’s the foundation for understanding ripeness, flavor potential, and storage performance across crops like avocados, mangoes, kiwifruit, and apples. In the debate of F-750 vs TR Turoni 532, both instruments are popular choices for non-destructive dry matter estimation. The… 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…

How Is Non-Destructive Quality Assessment of Fresh Produce Changing the Supply Chain?

The standard quality parameters monitored are color, texture, sugar, titratable acidity, and dry matter content. Several destructive methods of estimation exist for the parameters. Near-infrared spectroscopy is currently the only non-destructive method for quality control of sugars, titrable acidity, internal color, and dry matter content. Near-infrared spectroscopy can precisely and rapidly estimate all quality parameters,… 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…
