In Singapore, more than 30,000kg of okara are generated from soya milk and tofu production. Due to the high amount of insoluble dietary fiber and a unique, poignant smell of okara, it is often discarded as a waste product.
Despite okara's low palatability, it is rich in nutrients. Therefore, we have developed a cost-effective formulation to include okara in feed for abalone. The formulation can potentially be adapted and customised for other aquatic species.
TECHNOLOGY FEATURES & SPECIFICATIONS
The technology allows for an alternative nutrient source for animal feed allowing for the sustainability of food supply and reduction of food waste.
The formulation consists of a cost-effective plant-based functional ingredient, lowering the costs of feed for aquaculture farms.
The nutritional composition can be tailored for different species.
Increased growth rates and survivability.
Okara is used as a cost-effective feed for high-value abalone, a commonly cultured species of mollusc. Okara-based feed results in the beautiful purple colouration of the shell and increased growth and survivability of abalone. In comparison, the okara-based feed costs ~30% less than commercial feed used in the industry.
There is potential for okara to be included in feed for other aquatic species such as shrimp and fish.
