Technology Overview

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. RP has 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

Okara contains the following beneficial nutrients:

• 50% insoluble fiber

• 20% proteins

• 10% unsaturated fats

• Isoflavones

• Vitamins and minerals

   

   

Potential Applications

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.

Benefits

• An alternative nutrient source for animal feed allowing for sustainability of food supply and reduction of food waste.

• A cost-effective plant-based functional ingredient, lowering costs of feed for aquaculture farms.

• Nutritional composition can be tailored for different species.

• Increased growth rates and survivability.
