Raw Material
Commodity GroupFresh specialty fruit (Solanaceae; tree tomato)
Scientific NameSolanum betaceum Cav.
PerishabilityHigh
Growing Conditions- Cultivated in subtropical to tropical highland systems; commonly reported in Andean production zones at roughly 1,000–3,000 m elevation
- Prefers frost-free locations; frost events can damage shoots and foliage
- Orchards benefit from sheltered sites due to wind sensitivity in commercial production areas
Main VarietiesRed, Amber (yellow), Gold, Purple red
Consumption Forms- Fresh (halved/scooped or used as a fresh ingredient)
- Processed into sauces, chutneys, desserts, and beverages/juice
Grading Factors- Full cultivar-typical skin color (red or yellow) at harvest
- Minimum SSC (soluble solids) specification (e.g., 10% as a maturity check in some guidance)
- Uniform size/shape/color and freedom from defects, decay, and postharvest disorders
Planting to HarvestFirst fruiting is commonly reported around 18–24 months after planting under favorable conditions (timing varies by propagation method and environment).
Market
Fresh tamarillo (tree tomato, Solanum betaceum) is a niche specialty fruit with globally dispersed cultivation but limited, fragmented trade visibility in standard customs categories. Commercial production is concentrated in the Andean region—especially Colombia, Ecuador, and Peru—with New Zealand as a notable producer supplying domestic and export channels. New Zealand’s supply is strongly seasonal (roughly March–October, peaking mid-winter), while Andean highland production can support extended harvesting windows depending on altitude and local conditions. Market performance depends heavily on consistent fruit color/maturity at harvest and cold-chain discipline (around 3–4°C) to limit postharvest decay and physiological disorders.
Major Producing Countries- ColombiaCommercial production reported as part of Andean crop systems.
- EcuadorCommercial production reported as part of Andean crop systems.
- PeruCommercial production reported as part of Andean crop systems.
- New ZealandNotable producer with organized domestic and export marketing via industry bodies.
Major Exporting Countries- New ZealandExports reported into markets in North America, Oceania, and Asia; export activity is coordinated via sector arrangements and registered exporters.
Supply Calendar- New Zealand (North Island coastal growing areas):Mar, Apr, May, Jun, Jul, Aug, Sep, OctAvailability is reported March through October, with peak supply typically in July–August.
Specification
Major VarietiesRed (incl. Laird's Large), Amber (yellow ecotype), Gold, Purple red (Mulligan)
Physical Attributes- Egg-shaped/ovoid fruit typically marketed in full red or yellow skin color depending on cultivar
- Thick, often bitter skin (epicarp); pulp color varies by ecotype (red, yellow, purple)
Compositional Metrics- Minimum soluble solids content (SSC) of 10% may be used as a maturity/specification check
- Non-climacteric fruit with very low ethylene production in storage guidance
Supply Chain
Value Chain- Harvest at near full eating maturity (color-based) → sorting for size/color/defects → packing → rapid cooling → cold storage/transport → wholesale/specialty retail distribution
Demand Drivers- Specialty/exotic fruit demand in premium retail and foodservice
- Culinary versatility for fresh consumption and for sauces, chutneys, desserts, and beverages
Temperature- Optimum storage temperature commonly cited at 3–4°C with 90–95% relative humidity
- Below the minimum safe range, chilling injury risk increases (pitting/browning and higher decay susceptibility)
Atmosphere Control- Controlled-atmosphere (CA) handling guidance is not well established; UC Davis PREC notes no published information on CA for tamarillo.
Shelf Life- Under optimum cold storage (3–4°C; 90–95% RH), storage potential is cited at approximately 6–10 weeks
- Postharvest decay management is critical for longer storage and long-distance distribution
Risks
Pest And Disease Outbreaks HighTomato/potato psyllid (Bactericera cockerelli) and associated Liberibacter infection have been reported as highly disruptive to tamarillo orchards in New Zealand, with the potential to kill trees and force replanting; because tamarillo is a perennial crop, recovery can take multiple seasons, tightening exportable supply and increasing price volatility.Use area-wide monitoring and integrated pest management (IPM), including biological control options where approved, plus strict nursery hygiene and orchard replacement planning to maintain continuity of supply.
Postharvest Disease MediumFungal postharvest diseases (e.g., bitter rot) can rapidly reduce marketable quality, especially when stem/calyx infections progress into fruit during storage and transport.Implement preharvest IPM to reduce latent infections and apply validated postharvest sanitation/treatments (e.g., hot water dips cited in postharvest guidance) alongside cold-chain control.
Cold Chain Management MediumQuality outcomes are highly sensitive to temperature and humidity management; breaks in cold chain can accelerate decay, while overly low temperatures increase chilling injury and subsequent losses.Maintain continuous temperature logging and humidity control near recommended set points, and minimize handling steps that delay cooling.
Climate MediumTamarillo production is vulnerable to frost and wind damage, concentrating reliable commercial output in protected, frost-limited zones; extreme weather events can also reduce yields and fruit quality in coastal production areas.Prioritize sheltered sites, windbreaks, and frost-risk management; diversify sourcing across origins and microclimates where feasible.
Sustainability- Pesticide stewardship pressure where tomato/potato psyllid outbreaks drive frequent insecticide programs in commercial orchards
- Food loss and waste risk from postharvest fungal rots during extended storage and distribution
FAQ
What is tamarillo and what scientific name is used for it in trade and research?Tamarillo is also known as tree tomato and is the edible fruit of Solanum betaceum. Kew’s Plants of the World Online lists Solanum betaceum Cav. as the accepted scientific name.
How should fresh tamarillos be stored for international distribution?Postharvest guidance from the UC Davis Postharvest Research and Extension Center cites an optimum storage temperature of about 3–4°C with 90–95% relative humidity, with potential storage of roughly 6–10 weeks under good conditions. The same guidance warns that colder temperatures increase the risk of chilling injury and decay.
Which countries are most commonly associated with commercial tamarillo production?Research articles describe commercial production in the Andean region, particularly Colombia, Ecuador, and Peru, and also identify New Zealand as a notable commercial producer with organized marketing and export activity. Because trade data are often grouped under broader fruit categories, published global import rankings specific to tamarillo are not consistently available.
