Protecting Freshness in Transit: Ethylene Filters & Absorbents by BioXTEND

Are you in the business of crisp apples or delicate avocados? If yes, you can understand that these produce continues to live and breathe long after harvesting. A natural byproduct of this living process is ethylene. It is a colorless, odorless gas. This accelerates ripening and aging. While essential in controlled ripening, unchecked ethylene in storage or transit can lead to spoilage, weight loss, and reduced quality. BioXTEND, a company rooted in post-harvest science, offers a range of products— Ethylene Filter(s) and ethylene absorbent sachets—designed to reduce ethylene levels and preserve freshness across the supply chain.

Why Ethylene Control Matters

Ethylene acts as a ripening hormone. In confined spaces such as containers or storage rooms, this gas spreads throughout the produce, hastening the aging process and creating economic losses. Symptoms of ethylene exposure include softening, yellowing, weight loss, and diminished flavor. Left uncontrolled, ethylene can cost the industry billions and contribute significantly to global food waste.

Simple Ethylene Absorbent Sachets

BioXTEND’s ethylene absorbent sachets offer a zero-electricity, passive solution for small-scale shipments or packaging. Each sachet contains food-grade materials, including potassium permanganate and specialized granules, which oxidize ethylene into harmless compounds like carbon dioxide and water. Available in different sizes, the sachets are customizable to fit various package dimensions.

These sachets are easy to use: simply place one inside each produce box or crate. From packing to delivery, the sachet continuously removes ethylene and even captures bacteria and mold spores. Approved for use with organic produce, they are recyclable, non-toxic, and require no maintenance. Their ability to preserve color, weight, and freshness makes them an accessible solution for growers, exporters, and retailers.

Large-Scale Ethylene Filters for Refrigerated Transport

For bulk shipments and refrigerated containers, BioXTEND offers BXT Filters and BXT Shield. These single-use cylindrical filters are installed on container walls or pallets, absorbing ethylene while maintaining airflow and container hygiene.

BXT Filters are fitted into air-return grids using zip ties, capturing ethylene, bacteria, and mold. They are certified for safety and organic compliance and provide high absorption without impeding ventilation.

BXT Shield is a plastic-free, biodegradable alternative designed for pallet-level use. Each unit can be composted after use and even reused as organic fertilizer. Lightweight, recyclable, and approved for organic produce, these filters reflect a strong commitment to sustainability.

Integrated Filtration Units for Storage Facilities

BioXTEND also offers EthylGuard filtration units—powered systems designed for cold storage facilities. These plug-and-play devices circulate air through filtration modules filled with BioX granules. The system not only removes ethylene but also neutralizes spores, bacteria, and other low molecular weight gases. Designed with minimal maintenance needs and safety certifications, these units are ideal for larger-scale operations.

A Flexibility-Focused Portfolio

The BioXTEND ecosystem also includes granules and media modules that can be adapted to different systems, from sachets to industrial filters. These granules absorb ethylene, inhibit mold and rot, kill bacteria, and remove odors, making them one of the most versatile ethylene-absorbing materials on the market.

Impact on Food Quality and Sustainability

By implementing BioXTEND’s range, such as, ethylene filters and Ethylene Absorbent sachets, suppliers can significantly extend shelf life, reduce decay, and maintain produce quality from packing to shelf. Their organic-compatible solutions support sustainable practices and meet global food safety standards.

Ethylene may be invisible and odor-free, but its impact on post-harvest losses is very real. BioXTEND addresses this challenge with affordable, scalable, and eco-friendly filtration solutions. Whether you're a small grower improving boxed shipments or a distributor managing large cold chains, these products help preserve freshness, protect profits, and promote sustainability throughout the global produce supply chain.
