In the Binh Minh area of Tay Ninh province in southern Vietnam, farmer Nguyen Tuan Anh has built a greenhouse (nha mang) of about 1,000 square meters and is growing about 200 honey-variety passion fruit plants to European organic standards. Local media described the effort as a 'double benefit' (loi ich kep). The story is that simply moving cultivation from open field to under a roof lifts both quality and profit. At a glance it looks like one small farmer's capital investment, but this move is a piece of the upstream side of a trend in which Vietnamese passion fruit shifts from a region that sells fresh to a region that steadily supplies processing raw material. For those sourcing juice, puree, and frozen fruit in Japan, it is also a case that shows where raw-material quality is decided.
What changed under the roof
The change greenhouse cultivation brought is not flashy. Pests and filamentous fungi occur less, and reliance on chemical pesticides falls accordingly. It prevents the loss of flowers and young fruit dropping in the rainy season and stabilizes growth by curbing swings in sunlight and temperature. The Tay Ninh province public-service center provides technical support, and master's-degree holder Phan Thanh Quan and others advise on cultivation management. No flashy doubling-of-yield figure is cited, but the essence of the greenhouse is that it works on one point: reducing defective fruit and raising the share of fruit that meets grade. Because surface scratches and disease spots heavily sway the pricing of passion fruit, a roof that blocks external stress ties directly to yield.
Why upstream upgrading is advancing now
Behind it is the fact that demand for processing fruit is growing at a pace that overtakes fresh. Vietnam's passion fruit export value expanded from about US$20 million in 2015 to about US$222.5 million in 2023. In 2024 it dropped once to about US$172 million, but in 2025 it reached about US$202 million in the ten months of January to October alone, and US$240 million to US$250 million is projected for the full year. The lead in this growth is not fresh fruit but processed products such as frozen paste and concentrated juice. Frozen and IQF (individual quick freezing) technology has made long-term storage and uniform quality possible, and the pattern of beverage and food makers in the EU, US, Korea, and Japan taking it as raw material has taken hold. Fresh-fruit prices swing wildly, but processing raw material moves on a contract basis, giving the growing region an escape from price collapse. This structure, in which freezing supports demand even when fresh fruit plunges, is the durian case in which frozen processing has begun to absorb fresh-fruit plunges- it overlaps with that too.
The direction shown by the largest processor's capital investment
The downstream receptacle is also thickening. The largest passion fruit processor, Nafoods Group, posted full-year 2025 revenue of about 2.06 trillion dong (about US$79.38 million) and net profit of about 146 billion dong (about US$5.63 million), up 43.6% and 25.4% respectively from the prior year. The advanced processing complex it is building in central Vietnam has raised total investment to about 744 billion dong (about US$28.24 million), with annual raw-material processing capacity set at 100,000 tonnes. The more a plant that handles juice, puree, concentrate, and frozen fruit end to end builds up capacity, the greater the need to stabilize the quality and volume of raw material fed into it. A farmer's investment to reduce defective fruit in a greenhouse is two sides of the same coin as this capacity expansion. The move of growing regions into a stage of processing and shipping out is the trend in which Dak Lak province launched a fruit-processing cluster points in the same direction as well.
A customs boost and the scramble for raw material
In April 2025, Vietnam and China signed a quarantine protocol for fresh passion fruit, opening exports via the formal route. With a market of over a billion people opened head-on, inquiries for fresh fruit may strengthen a notch further. What cannot be overlooked here is that fresh-use and processing-use compete for fruit from the same fields. If the fresh-fruit market rises, processors are pressed to strengthen their ties with growing regions to secure raw material. Farmers who, like greenhouse growers, can steadily supply fruit that meets grade tend to be in high demand for both fresh and processing. The opening of the China window means, for Japanese buyers seeking processing raw material, that competition has increased.
What Japanese procurement should read into this
For import and procurement managers handling juice, puree, and frozen passion fruit in Japan, this greenhouse story carries two implications. First, raw-material quality is decided largely in the field, not the plant. Fruit whose disease, pests, and weather risk have been curbed in a greenhouse differs in processing yield and in the uniformity of aroma and flavor. It is worth confirming not just the unit price but what kind of cultivation-management region the raw material came from. Second, supply stability depends on a region's cultivation style. A region relying solely on open fields has supply that wobbles with the weather, while a region that has adopted greenhouses and advanced management is resilient to lean seasons and bad weather. If you set up a long-term contract or an annual supply plan, choosing regions and processors with a higher ratio of the latter carries less risk. Rather than being swayed by fresh-market price moves, you need the mindset of designing in advance whom to partner with for a processing-raw-material supply network. This move beyond fresh thinking is the move to read Vietnam's first-half produce results through a processing lens.
Summary
Tay Ninh's 1,000-square-meter greenhouse is, on its own, only a small capital investment. But placed within the larger trend of passion fruit being built into the world market as processing raw material, its meaning comes into view. A farmer's effort to lift fruit quality under a roof supports the largest processor's 100,000-tonne capacity and ultimately reaches the beverage and confectionery shelves of Japan. What the Japanese procurement side can do is less to chase the near-term fresh-fruit market than to judge which regions have advanced this upstream upgrading. The next time you take a quote, it is worth adding one question about the backing for a region's cultivation style and processing capacity.
