Roselle

Roselle (Hibiscus sabdariffa) is a deep-rooted, bushy, shrubby plant that has yellow, green and red colors edible leaves, stems and flowers. It is native to the tropics, but can also be found in warm subtropical regions around the world. Roselle has an intriguing and complex journey to dinner plates. From its production in the fields, to its arrival on store shelves, to its preparation and consumption, this fascinating plant has a complex history and interesting scientific elements to it.

The Production of Roselle

The production and growth of Roselle begins when the seeds of the plant are planted and cultivated. Roselle takes between 45 to 60 days to reach maturity. During this maturation period, the abundance of leaves, stems and flowers are created. Soil pH is a key factor to Roselle’s growth and for optimal fruiting and flowers the plant requires a soil pH of 6.5-7.5. While growing, the stem of the plant grows to an average of 1.5-3 meters in height. The bush structure of the plant helps it use sunlight effectively, allowing it to thrive in a variety of climates. During the harvest season, mature Roselle flowers are cut off from the stems and placed in baskets for transportation.

Harvesting & Postharvest handling

Harvesting of Roselle is usually done by hand, as they are too delicate to be harvested with mechanical harvesters. The flowers are the first to be harvested, followed by the stems and the leaves. The harvested flowers are placed in baskets and transported to a packing house. From the packing house, the Roselle flowers are sorted by size, quality, and color. The flowers are then washed in cold water to remove dirt and pests, followed by drying. The drying process is done in a temperature-controlled dryer at between 28-40°C. The dried Roselle flowers are then sealed in plastic packaging for transport. The flowers are then sent to food processing factories, ready for further processing.

Processing of Roselle

At the factory, the Roselle flowers are processed into different products. The individual products are based on the customer’s request and the type of market the product is going to. For example, Roselle can be processed into tea, dried flower petals, and jellies or jams. In processing the Roselle, the petals are cut, dried and packaged for making tea, jellies and jams. Alternatively, large processing machines such as grinders, blenders and dryers can be used to reduce the size of the flower petals and to dry them. Roselle can also be processed into powder forms, which allows for its incorporation into doughs, batters, smoothies and more.

Packaging & Labelling

After the processing is done, the Roselle products are packed into containers or bags for transport. All the containers must meet safety regulations in order to be transported for food sale or commercial products. They must be clean and labeled properly with details regarding the manufacturing date, expiration date, ingredients, nutritional facts, and other relevant information. Good labels should make it easy for the consumer to know what’s inside and should also include the company logo and address.

Transportation

Roselle products are usually transported using ships, planes, trucks, and trains. Depending on the distance, the method of transportation varies. For example, shipments that are sent overseas are usually transported by ships, whereas domestic shipments may be transported by trucks. During transportation, the temperature of the container must be regulated to ensure that the Roselle products do not spoil. The packaging of the product must also be designed to keep the product safe and unspoiled during its journey.

Consumption & Preparation

Roselle has a number of uses and it can be used as a food accompaniment, beverage, and ingredient. The petals can be taken from the flower buds and added to salads, herbal tea, and desserts. The petals can also be added to a variety of dishes for their color, texture, and taste. For example, Roselle can be used in stir-fries, curries, juices, and jams. The leaves and stems can be cooked and eaten like any other green leafy vegetable. Roselle can also be used in beverages such as tea and agua fresca.

Conclusion

Roselle is a highly versatile and nutritious plant that has a range of uses. Its deep roots allow it to thrive in a variety of climates and its edible parts make it a valuable addition to many dishes. Its complex journey begins in the fields where it is planted and cultivated, continues through the harvesting and post-harvesting processes, and ends with its consumption and preparation. From the farmer’s field to the dinner plate, Roselle is a great addition to many meals and a fascinating study due to its fascinating production, transportation, and preparation.
