THE SECRET TO DURIAN HARVESTING THAT HELPS HUNGHAU FOODS BECOME ONE OF VIETNAM’S LEADING AGRICULTURAL SUPPLIERS

Durian has long been hailed as the “king of fruits” thanks to its unique flavor and high economic value. Below are the key secrets that have helped a select few Vietnamese enterprises  including HungHau Foods successfully bring IQF durian to global markets and become one of Vietnam’s most trusted agricultural exporters.

HungHau Foods Ensures Optimal Durian Ripeness

According to experts, durians should never be harvested while still unripe, as at that stage, the flesh has not yet developed sufficient soluble solids, the seeds remain soft, and the flavor is incomplete. The ideal time for harvesting is when the fruit reaches 85–90% physiological maturity, depending on the variety, typically determined by days after flowering (DAF) or days after fruit set (DAFQ).

To identify whether a durian has reached physiological maturity, several signs are observed. The stem begins to turn light brown, and small cracks may appear near its base. The spikes become rounder, more spaced out, and moderately firm; when tapped, the shell produces a deep “thud-thud” sound instead of a hollow one.

For export-grade durians, companies usually harvest the fruits just before they naturally drop, ensuring consistent quality and flavor. For example, the Ri6 variety is typically cut 85–95 days after fruit set, while the Monthong variety is harvested around 100–110 days.

After being harvested, durians continue to respire and gradually ripen. Under normal temperature conditions of 25–30°C, the fruit typically begins to ripen within 3–5 days. During this period, it should be stored in a cool, well-ventilated area, away from direct sunlight. For domestic consumption, durians are usually ripened for an additional 2–4 days to enhance their rich flavor, soft golden flesh, and signature aroma.

For late-ripening varieties or fruits harvested slightly early, the ripening period may extend to 4–6 days. This step is crucial to ensure the fruit develops its full flavor and texture before being processed or distributed.

HungHau Foods focuses on developing a comprehensive ecosystem connecting farms and factories.

As a pioneer in durian IQF processing, HungHau Foods is also a reputable agricultural exporter with a diverse product ecosystem. Each exported durian segment is not merely a commercial product — it carries the pride of Vietnamese agriculture reaching out to international markets.

The key differentiator that empowers HungHau Foods lies in its closed-loop agricultural ecosystem, built upon a network of modern, synchronized factories:

• HungHau Vegetable Co., Ltd. (Lai Vung – Dong Thap):
  As the core processing center, this facility applies advanced IQF (Individual Quick Freezing) technology to preserve the full flavor, color, and natural nutritional value of agricultural products. With a state-of-the-art factory that meets international standards, HungHau Foods has affirmed its pioneering position in IQF durian processing. The quick-freezing technology allows the durian segments to be seedless while retaining their fresh color, taste, and nutritional content as if just ripened. Every day, tons of Ri6 and Monthong durians from HungHau Foods are exported worldwide, contributing to enhancing the global presence of Vietnamese agricultural products.
• Nha Man Co., Ltd (Sa Dec – Dong Thap):
  Specialized in producing a diverse range of products such as noodles, pasta, dried fruits and vegetables, and Ochao eco-friendly rice straws.
• OCHAO Corporation (Cu Chi – Ho Chi Minh City):
  Focused on developing various confectionery lines including crackers, cookies, soft cakes, waffles, snacks, and candies  offering consumers a rich and delightful experience.

Through the seamless coordination among these factories, HungHau Foods not only ensures strict control over quality, safety, and sustainability, but also has the capacity to supply large quantities of agricultural products to over 80 countries and territories.

HungHau Foods also places great emphasis on maintaining the quality of agricultural products sourced from its extensive farming network across Vietnam. The company directly partners with Ri6 and Monthong durian farms in the Southeast and Central Highlands regions that meet cultivation standards. This enables HungHau Foods to maintain a stable year-round supply while strictly controlling pesticide residues — ensuring absolute safety for consumers. Moreover, all production processes strictly comply with international food safety standards, establishing a solid foundation for Vietnamese durians to reach global markets.

With a long-term vision and a sustainable development strategy, HungHau Foods continues to affirm its position as one of Vietnam’s leading agricultural exporters — accompanying farmers, partners, and customers on the journey to bring Vietnamese agricultural products to the world.

At HungHau Vegetables Factory, every worker is thoroughly trained to become a true “expert” in durian grading.
