Soursop, also known as Graviola, is one of Vietnam's prized tropical fruits, famous not only for its delicious taste but also for its high nutritional value. This fruit has become a symbol of Vietnam's agricultural pride, and through the tireless efforts of farmers, combined with modern agricultural technology, Vietnamese soursop has reached global markets. Particularly, the collaboration between farmers and agricultural experts has created a sustainable development model, improving the growth of the fruit while enhancing its value. This partnership has resulted in fresh, high-quality soursop ready to conquer international markets.
1. Soursop: The Green Gem in The Tropical Garden
Soursop is a unique fruit with a prickly green skin that turns yellow when ripe, with soft, creamy white flesh inside. It offers a sweet-tart flavor that provides a refreshing and pleasant experience. Not only is it a popular snack, but soursop is also rich in vitamins, minerals, and fiber, promoting overall health, aiding digestion, and preventing certain illnesses.
The fruit is not only delicious but also offers numerous health benefits. Soursop is packed with essential nutrients, including vitamin C, antioxidants, and a variety of vitamins and minerals, such as B vitamins, iron, calcium, and magnesium. These nutrients support the immune system, promote healthy skin, and improve digestion. The high fiber content in soursop is especially beneficial for maintaining digestive health, aiding in regular bowel movements, and promoting gut health.
2. Soursop Harvest Season in Vietnam
Soursop in Vietnam is typically harvested from June to October, though the harvest period may vary depending on the region and climatic conditions. The harvesting process requires meticulous care to protect the fruit from damage while preserving its natural flavor.
The harvest process is carried out with great care, as farmers strive to protect the fruit from damage, preserving its natural flavor and ensuring top-quality produce for consumers. The dedication to maintaining freshness and quality during the harvest has contributed significantly to soursop’s reputation as one of the finest tropical fruits.
3. Vietnam's Climate: The Ideal Environment for Mangosteen
Soursop, a tropical fruit that thrives in hot and humid climates, grows best in temperatures ranging from 25°C to 30°C, which makes it ideally suited for Vietnam’s environment, particularly in the Mekong Delta. This region's tropical weather, characterized by high humidity and abundant rainfall, provides the perfect conditions for soursop cultivation. The warm temperatures encourage rapid growth and abundant fruiting, while the fertile soil in many areas of the Mekong Delta ensures that the plants receive the essential nutrients they need to flourish.
However, proper irrigation is critical for achieving optimal growth, particularly during the dry season when rainfall is scarce. To maintain healthy soursop trees and ensure high yields, farmers in Vietnam use advanced irrigation techniques, such as drip irrigation and sprinkler systems. These methods help regulate water distribution, prevent overwatering or underwatering, and reduce water waste. Drip irrigation, in particular, is highly effective in delivering water directly to the root zone, promoting efficient water use and minimizing evaporation. This system not only helps conserve water but also enhances the overall growth of the plants, resulting in larger, healthier fruits.
4. Main Mangosteen Variety
- Dien Soursop:
The Dien soursop variety is renowned for producing large, robust fruits that have a distinctive dark green skin when unripe, which transforms into a lighter shade as the fruit matures. Inside, the flesh is bright yellow, with a smooth and creamy texture. Known for its excellent sweetness and slightly tangy flavor, Dien soursop is often regarded as one of the best-tasting varieties of soursop in Vietnam. The creamy consistency of its flesh makes it perfect for smoothies, desserts, and fresh consumption. This variety is particularly sought after in local markets for its premium flavor and texture, and its popularity continues to grow in export markets.
- Thai Soursop:
Thai soursop, characterized by its oval-shaped fruits, features a smooth, light green skin that becomes more yellowish as it ripens. The flesh inside is a pale yellow, with a slightly less creamy texture compared to other varieties, but still tender and juicy. One of the key features of Thai soursop is its remarkable productivity, as this variety is known for its high yield and consistency. The fruits are generally uniform in size, which makes them easier to pack and export. Thai soursop also stands out for its long shelf life, making it suitable for both local and international markets.
- Monthong Soursop:
The Monthong soursop variety, originally from Thailand, is highly regarded for its large size, thick flesh, and rich, sweet flavor. The fruit typically has a bright green skin that turns yellow as it ripens, and it features a firmer, denser texture compared to other soursop varieties. Monthong soursop is especially known for its superior sweetness, which is more pronounced and less tangy than other types. This makes it particularly popular for making juices, ice creams, and other sweet treats.
