How Degreening of Citrus Fruits Enhances Appearance and Quality

Artificial degreening changes only citrus peel color and does not affect other quality parameters. Several citrus factors, like maturity at harvest and cultivar-specific ethylene sensitivity, will influence degreening success. Postharvest degreening is the standard procedure and requires careful consideration of cultivars to determine atmosphere conditions, ethylene concentrations, and exposure duration to achieve the desired results.… Continue reading…

How the Fruit Ripening Process Affects Freshness and Quality

Respiratory rate, ethylene sensitivity, and production are the main criteria for differentiating ripening patterns. Respiratory peaks that trigger ethylene production start the ripening process in climacteric fruits. Ethylene sensitivity, production, and respiration hike are minimal or absent in non-climacteric fruits. Several fruits show varying degrees of ethylene sensitivity and production and defy neat classification in… Continue reading…

Fruit Cuticle Impact on Postharvest Quality: What You Need to Know

The cuticle is crucial in the postharvest stages as it is the interface between fruits and external biotic and abiotic conditions. Cuticle impact on postharvest quality has several protective functions and is a barrier to water loss, mechanical injuries, UV light, and pest and microbial attacks. It can also alter postharvest fruit firmness and appearance.… Continue reading…

How to Improve Post-harvest Quality in Fresh Produce

Factors affecting post-harvest quality are determined by harvest time, method, and fresh produce maturity. Subsequent postharvest handling during precooling, sorting, grading, packaging, storage, and transport conditions will also influence fresh produce quality and marketing time. Significant differences exist in postharvest technology between developing and developed countries. Fresh produce is highly perishable and suffers from physical… Continue reading…

Fruit Respiration Impact on Fruit Quality

Even with established commodities, different cultivars or growing regions may require unique benchmarks. A custom model ensures your measurements reflect your specific needs and conditions.

Fruits continue to respire after harvest as they are still alive. Aerobic respiration that uses oxygen is the norm, but when oxygen levels drop, anaerobic respiration or fermentation starts. Aerobic respiration is necessary for the development of fruit quality and ripening. Excessive fruit respiration is detrimental in the postharvest stages, as it can cause fruit… Continue reading…

The Impact Transpiration Has on Fruit Quality

Without a quantitative maturity standard, harvesting becomes a guessing game. A custom NIR model gives you accurate, reliable data to make informed decisions.

Fruit transpiration occurs through the fruit skin, lenticels, calyx, and stem scar. Preharvest fruit transpiration is good as it drives the accumulation of assimilated and dry matter to improve fruit quality. Postharvest fruit transpiration is undesirable, leading to shriveling, weight loss, wilting, loss of quality, shelf-life, and reduced profitability. Fruit transpiration causes most weight loss… Continue reading…

How NIR Spectroscopy and Gas Analysis Can Improve Food Security

Avoiding food loss and waste could be one way of fixing food security. According to new estimates, about 40% of food goes to waste, of which 50% is lost on farms. Of course, consumers have to tackle food waste, but food loss between farms and retailers needs to be collectively fixed by the food production… Continue reading…

Ethylene Gas Analysis & Heat Stress Treatment in Tomato Plants

Ethylene gas is produced due to stress, as it is a signaling molecule involved in stress response by plants. Hence, scientists use ethylene measurements as one of the standard procedures to monitor stress effects in crops.
