Overview
Guava (Psidium guajava) is a tropical fruit originating from Central America, now widely cultivated in Asia, Africa, and other warm regions. The 'watermelon guava' variety refers to cultivars with pinkish-red flesh resembling watermelon. Botanically classified as a berry, guavas grow on small evergreen trees and are harvested when slightly soft to the touch. The fruit is valued for its nutritional profile, containing 4-5 times more vitamin C than oranges. Commercial varieties differ in size (5-12 cm diameter), skin color (green to yellow when ripe), and flesh color (white, pink, or red). Major producers include India, China, Thailand, and Mexico.
Product Features
Guavas have a distinctive sweet-tart flavor with floral notes, often described as a cross between pear and strawberry. The edible seeds are softer than those in other fruits, allowing whole consumption. The skin is thin but sometimes removed due to its slightly bitter taste. Nutritionally, guavas provide dietary fiber (9g per cup), folate, potassium, and antioxidants like lycopene (especially in red-fleshed varieties). The fruit emits a strong, pleasant aroma when ripe, making fragrance a key quality indicator. Shelf life ranges from 2-5 days at room temperature or up to 2 weeks when refrigerated.
Main Uses
In food industries, guavas are processed into juices (popular in Latin America), jams (like Brazilian goiabada), and fruit preserves. The pulp serves as filling for pastries and ice creams. Dried guava slices and candied products are common snacks in Asian markets. Beyond culinary applications, guava leaf extracts are used in traditional medicine for anti-diarrheal properties. The wood is valued for smoking meats, while essential oils from leaves appear in cosmetic formulations. Emerging uses include guava powder as a natural food coloring and flavoring agent.
Culture and Development
Guava cultivation dates back to 800 BC in Peru. Spanish and Portuguese colonizers spread the fruit globally during the 16th-17th centuries. In Taiwan (where 'watermelon guava' is prominent), farmers developed seedless varieties through selective breeding. The fruit holds cultural significance in many regions. Filipinos use guava leaves in folk healing, while Hawaiians consider it an invasive species. Modern cultivation focuses on disease-resistant hybrids like 'Ruby Supreme' and 'Tropic White'. Annual global production exceeds 55 million metric tons, with increasing demand for organic varieties.
B2B Procurement Guide
When sourcing guavas commercially, consider seasonality (peak varies by country) and transport methods (refrigerated for international shipments). Preferred varieties differ by market - Asian buyers favor crisp textures while Latin America prefers softer fruits. Inspect for fruit fly damage (a common issue) and request pesticide residue reports. For processed products, verify pasteurization methods and brix levels (sweetness). Contract farming arrangements are common in India and Thailand to ensure consistent supply. Minimum order quantities typically start at 1 metric ton for fresh fruit exports.
