Consumer demand for ready-to-eat avocados has transformed the way the fresh produce industry approaches ripening. What was once considered a specialist service has become an essential part of the supply chain, helping growers, importers, ripeners and retailers deliver fruit with consistent quality, predictable ripeness and reduced waste.

This evolution reflects the growth of the global avocado market. According to the latest OECD-FAO Agricultural Outlook, avocados are expected to remain the fastest-growing major tropical fruit over the next decade, with global production projected to reach around 16 million tonnes by 2035. The report also forecasts that avocados will become the world’s most traded major tropical fruit by 2035, driven by rising demand in the United States, Europe and other high-income markets.

As avocado consumption continues to rise across North America, Europe, Latin America and Australia, commercial ripening programs are becoming increasingly sophisticated, combining a deeper understanding of fruit physiology with reliable ethylene application and modern ripening technologies.

Knowing the fruit
One key challenge in commercial avocado ripening is that no two batches behave the same way. Factors such as production region, maturity at harvest, time off the tree, shipping conditions and previous postharvest treatments all influence how avocados respond during ripening.

According to Mary Lu Arpaia, cooperative extension specialist at the University of California, avocado ripening has evolved significantly over the years. While it was traditionally carried out at packinghouses, today it increasingly takes place at retail and wholesale distribution centers. Advances in ripening room technology, temperature management, carbon dioxide control and ethylene application have made it possible to deliver more consistent fruit quality closer to the point of sale. Because ripe avocados become particularly fragile, this shift also helps reduce handling after ripening, preserving fruit quality until it reaches consumers.

“Successful avocado ripening starts with knowing the fruit: where it comes from, how long it has been off the tree, its maturity, shipping conditions and any postharvest treatments,” says Arpaia. “Ethylene application helps reduce fruit-to-fruit variability, shorten ripening time and deliver a more uniform product to the end user.”

Ultimately, successful avocado ripening is never the result of a single factor. It depends on understanding the fruit, well-managed ripening conditions and reliable ethylene application.

Consistency is everything
While understanding the fruit is fundamental, successful avocado ripening also depends on maintaining stable conditions inside the ripening room. “An ethylene application system must provide a uniform level of gas at a constant rate and work in tandem with a well-designed ripening room. Airflow is equally important to ensure ethylene is distributed evenly throughout the room,” says Arpaia.

Greg Akins, president & CEO of Catalytic Generators, agrees. “For the fruit to start ripening uniformly and dependably, ripeners need to maintain at least 100 ppm of ethylene throughout the application period,” he says. “Continuous ethylene production helps maintain the required ethylene level, even when minor air leaks occur, and quickly rebuilds them when doors are opened.”

This explains why reliable ethylene application has become a key component of modern avocado ripening programs. It is not simply about introducing ethylene into a room, but about maintaining the right concentration, distribution and consistency throughout the treatment period.

This is the approach behind Catalytic Generators’ Easy-Ripe® systems, which are designed to provide continuous, reliable ethylene production for commercial ripening operations. For Akins, this is exactly what customers are looking for today: reliable equipment, repeatable results, trusted service and people who understand the fresh produce industry.

Developments in ripening
Commercial avocado ripening has changed significantly over the past decade. Akins says that what was once handled by a limited number of growers and specialist operators has become standard practice across the industry, including at many retail distribution centers. This shift has been driven by stronger sales, lower shrink and faster inventory turnover, while helping suppliers consistently deliver fruit that meets consumers’ ready-to-eat expectations.

Across the industry, professionally managed ready-to-eat programs continue to demonstrate the value of commercial ripening by improving quality consistency, enhancing consumer confidence and encouraging repeat purchases.

Unlike bananas, however, avocados present additional operational challenges. Once they reach their climacteric peak, they generate substantially more heat, requiring greater cooling capacity and carefully designed airflow to remove the heat of respiration from fruit located at the center of each pallet. For ripeners, success depends on managing every stage of the process. Reliable ethylene application must work alongside effective temperature management, carbon dioxide control and proper airflow to ensure fruit ripens uniformly and reaches the market at the optimum stage of maturity.

Supporting international expansion
As commercial avocado ripening continues to expand around the world, regulatory compliance is becoming increasingly important. In several countries, ethylene is classified as a regulated plant protection product, requiring official registration before it can be commercially applied to fruit.

Catalytic Generators recently obtained approval for avocado ripening in Italy and it continues to expand its regulatory footprint internationally. These approvals provide customers with the confidence that they are using a legally authorized solution while supporting the continued growth of commercial ripening programs in new markets.

The future of avocado ripening
Ready-to-eat avocados have become the consumer standard, and the industry continues to evolve to meet growing expectations for quality and consistency. “The next generation of ripening programs will increasingly combine reliable ethylene application with digital tools such as ripeness sensors, remotely monitored ethylene generators and connected ripening rooms, giving operators greater visibility and control throughout the process,” says Akins.

Ultimately, successful avocado ripening will continue to depend on the combination of science, technology and practical experience. “Understanding the fruit remains the foundation of every successful ripening program,” says Arpaia. “Combined with reliable ethylene application and smarter ripening technologies, this knowledge will help the industry deliver the consistent, ready-to-eat quality that today’s consumers expect.”
