It is primarily consumed as root vegetables for the starchy corms or tubers as well as a leaf vegetable.

 

Eating Taro

The corms are usually boiled, steamed or baked. However, taro may also be fried to make chips that are like fries or crisps. Taro is also cooked in curries, coconut milk and sweet dishes. The taro leaves and roots must be cooked properly before eating. Otherwise due to chemicals present in the plant will make the vegetable taste bitter. Furthermore, taro is toxic in raw form because of the high oxalates content. However, the dangerous substance is removed when cooked or if steeped overnight. When cooked, taro is a nutritious addition to both sweet and savoury meals. Consumption of frozen taro is getting more common in the western world due to its long storage time and convenience.

Production

Taro is a staple in Africa and the South Pacific islands and world production averages 9.5 million tonnes. The main taro producing countries are Nigeria, China, Cameroon and Ghana. To produce taro, farm equipment requirements are a tractor, bed former, spray equipment. Harvesting is quite labour intensive as it is all done manually. Most South Pacific island countries grow taro organically which is healthier and tastier. However, it may not always be organically certified. These countries are now producing substantial amounts of frozen taro which is very popular and frequently eaten.

 

Harvesting and Processing

Taro roots are ready to harvest when the leaves become smaller. The leaf stalks will shorten, and the corm pushes above the soil. The quality of the crop deteriorates if left in the ground for too long. With the innovation of freezing technology, more and more mobile processing plants are set up either at the farm gate or near farms to processing frozen taro.

 

Following harvest, tops are trimmed off the roots and possibly graded by size. Corms are packed into fibreboard cartons and usually freighted by road or rail to markets at capital cities, under ambient storage temperature for fresh produce. Taro should be consumed within two weeks; however cold storage will extend their shelf life. Frozen taro will store for up to two years.

Frozen taro is also sourced from Fiji and Samoa; however, they are imported from Asian countries too. Frozen taro market is growing significantly in Australia, New Zealand and North America.
