Fish Processing Enzymes

Enhance the quality and value of fish-processing byproducts

Fish processing generates valuable byproducts that are high in protein and lipids, such as viscera, skin, tails, heads and frames. But it’s common for fish processors to fail to extract the full value of these byproducts by relying on inefficient secondary processing or methods that require heat, chemicals or machinery.

DuPont FoodPro® fish processing enzymes help to unlock value from these nutrient-rich byproducts by converting them into nutritional supplements, enabling you to derive additional revenue and create less food waste. These supplements can be used in pet food, biodiesel, fertilizer, agricultural products, and animal and fish feed.

How We Help

Sustainability

Roughly 30% of our food is wasted annually, generating close to 1.3 billion tons of food waste. This amounts to losses of roughly US $1 trillion globally. DuPont enzymes can help extend the shelf life of food and reduce food waste. This avoids both wasted resources and environmental emissions associated with decomposing food waste.

Our fish processing enzymes support these objectives of the United Nations Sustainable Development Goals.
