What Are Brix Measurements and Are They Crucial in Fresh Produce?

October 20, 2025 at 5:17 pm | Updated October 20, 2025 at 5:17 pm | 12 min read

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…

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…
