What Causes Postharvest Senescence in Fresh Produce

Senescence is one of the top two postharvest processes that cause food loss of fresh produce by curtailing shelf life. Ethylene production, programmed cell death, and cellular energy supply are significant processes associated with senescence in postharvest fresh produce. The mechanisms by which the three processes cause senescence are not entirely understood. Premature senescence and… Continue reading…

How to Improve Fresh Produce Supply Chain Risk Management for Better Food Safety

Supply chain risk management for fresh produce can include macro-level, external, and internal risks. Macro and external risk factors are outside a business’ control and can affect more than one location in the supply chain. Internal risks that cover a business’s operations, processes, and control measures can be managed using controlled atmosphere facilities and monitoring… Continue reading…

How Do the Effects of Ethylene on Flower Quality Impact Floriculture?

Ethylene is one of the main factors affecting flower and ornamental plant quality and longevity in the entire floriculture supply chain. Ethylene inhibits growth, branching, flower bud abortion, and leaf and flower abscission, reducing the quality and longevity of floriculture products. Floriculturists can increase ROI by monitoring and reducing ethylene levels in greenhouses, storage, distribution,… Continue reading…

Postharvest Technology for Non-Climacteric Fruits: Best Practices and Benefits

Non-climacteric fruits have a short storage life as they must be harvested ripe. Several steps, like precooling and treatments, prepare the non-climacteric fruits for quality retention. Modified atmospheric packaging, controlled atmospheric storage, and different packaging systems maintain suitable environmental conditions during storing, transportation, and marketing to extend shelf life. Ripening is the last stage of… 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…

Understanding Fresh Produce Spoilage: Five Causes and Prevention

Various reasons are behind the fresh produce spoilage of the vast diversity of fruits and vegetables. Respiration, transpiration, microbial growth, damage and injury, and internal degradation are common causes. Product-specific temperature thresholds, relative humidity, ethylene, oxygen, and carbon dioxide are the five ambient conditions that determine the spoilage rate. Controlling ambient conditions helps to reduce… Continue reading…

How to Extend the Shelf Life of Fresh Produce: Innovations in Gas Monitoring and Controlled Atmospheres

Extend the shelf life of fresh produce: Oxygen, carbon dioxide, and ethylene are monitored in all postharvest stages, including controlled atmosphere storage and transport facilities and modified atmosphere packaging. Ethylene is monitored to manage and maintain fresh produce quality, ripeness, and shelf life by detecting ethylene accumulation hotspots. Oxygen and carbon dioxide estimation helps to… 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…

Optimizing Quality and Shelf Life with Fruit Ripening Programs

Fruit ripening programs artificially ripen climacteric fruits and degreen non-climacteric citrus fruits. The fruit ripening program has to be designed to ensure that all quality parameters are developed to give the targeted color, taste, and flavor. Each fruit’s ripening program has specific recommendations to adjust the environment and ethylene concentrations to get the desired fruit… 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…
