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…

What Is the Best Plum Harvest Maturity Index?

Taste or sugar/acidity ratio is the plums’ most reliable harvest maturity index. A new plum harvest maturity indicator has been developed that combines firmness at maximum maturity with sugar content. No single quality parameter can be used alone as a harvest maturity index for plums. Plum Characteristics Plums, which are classified as climacteric fruits, have… Continue reading…

What Is the Avocado Harvest Maturity Index and How Is It Measured?

Physical and chemical parameters and crop chronology are avocado harvest maturity indices. Physical quality parameters, especially appearance, are commonly used worldwide. Dry matter content measured by near-infrared spectroscopy-based devices has become the industry standard maturity index. Sugar content is not a reliable avocado harvest maturity index. Avocado fruits go through four stages of maturity and… Continue reading…

How to Determine the Right Avocado Harvest Maturity Index for Optimal Quality

Physical and chemical parameters and crop chronology are used as harvest maturity indices for avocados. Physical quality parameters, especially appearance, are commonly used worldwide. Dry matter content measured by near-infrared spectroscopy-based devices has become the industry standard maturity index. Sugar content is not a reliable avocado harvest maturity index. Avocado fruits go through four stages… Continue reading…

Five Significant Research Findings on Fruit Quality Management in 2024

Fruit quality studies in 2024 aim to future-proof food production against the vagaries of climate change and to meet increasing demand. As in previous years, the focus remains on eradicating chemicals to improve food and environment safety. Research on AI-based models and tools is a standard theme, but it is diversifying to produce cost-effective versions… Continue reading…
