Can you imagine that nearly 1 million tonnes of aquaculture waste are discarded each year across Vietnam?
Do you know most fish waste is processed in a way that hasn’t fully utilized its huge commercial value? Want to turn fish waste into new business opportunities? Here is the answer to turn the seemingly useless fish waste into treasure, in a safer, more efficient and sustainable way.
Fish Seasoning and Extract: elevated flavor and aroma
Flavor and aroma is the king to seasoning products. The kind of amino acid in fish seasoning affects the taste profile. An enzymatic processing solution works on hydrolyzing fish materials that can help produce the desired peptides and amino acids and thus obtain an enhanced flavor and aroma in the fish seasoning product, making it more likely to be preferred by consumers. Besides, enzymes are classified as processing aid thus there is no need to add this to the ingredient list in the product label.
Fish Sauce: increased productivity and production capacity
Most fish processing method involves the breaking down of their protein components, also called protein hydrolysis. By adding enzymes, the process of protein hydrolysis can be accelerated and the overall processing time shortened. For example, by adding protease to the liquefaction stage in fish sauce processing, the usual needed time for the whole process of 10 months can be reduced to 6 months, as protease can significantly reduce the liquefaction time of 4 months to just 1 day. Significantly reducing the processing time means better productivity and possible cost savings in overall production costs.
Marine Collagen: naturally processed, faster
In the production of collagen peptides, fish skin can be used as raw material, and the extraction process usually involves the use of chemicals or acids. Enzymes are natural solutions that aid in processing the skin into collagen peptides, which not only is efficient but also helps generate better peptide distribution. The use of enzymatic solution can reduce chemical impact on the environment by reducing the use of certain chemicals, without sacrificing the quality, leading to more efficient processes and better sustainability.

Fish Fertilizer: sustainably sourced, and efficiently produced
The growing population demands for increased crop productivity. On the other hand, the rise in awareness regarding the effects of chemical fertilizers on humans drives the growth of natural fertilizers. Fish viscera is currently being utilized for animal feeds with a value below $1 per kg or being thrown away. Viscera can be utilized as a high-quality natural fish fertilizer that is a good source of burn-free nitrogen along with other primary nutrients. Leveraging an enzymatic technology allows the liquefaction time shortened and sedimentation reduced. The process that usually takes 14 days can be done in only 1-3 days.
Aquafeed Ingredient: increases feed palatability, nutrient uptake, and digestibility
More than 50% of the protein-rich stickwater is being thrown away. Those are tonnes of uncaptured valuable nutrients! The portion being utilized today for animal feeds needs a long time and energy to process. By adopting an enzymatic processing solution, stickwater can be processed faster thus lower energy requirement. Moreover, enzymes can generate 3,000 Da and help to have better micro stability which increases the value of these aquafeed ingredients . This in turn increases feed palatability, nutrient uptake, and digestibility.
What is enzyme? How does it work?
Enzymes are proteins produced by all living things and are found in bacteria, fungi, plants, and even in our human body. Enzymes have specific functions and act as catalyst for specific reactions and act on specific substrates. Protease, a kind of enzyme acts on protein. Materials rich in protein such as fish, protease aid in the faster breakdown of large protein molecules into smaller peptides and amino acids.
Enzymatic solutions are easy to adapt to existing production processes with just slight adjustments. Embracing enzyme solutions can offer you the opportunity to produce higher quality or more differentiated products, expand your product portfolio, explore new horizons, and drive growth and diversification for your business.
By understanding what enzymes are and how they can contribute to better ways of utilization, you can rethink the value it can bring to your business, whether you are an existing fish processor or considering processing fish in the future. Novozyme’s enzyme solutions can provide significant benefits to fish processing businesses in Vietnam’s aquaculture industry by empowering them to maximize productivity, profitability, and sustainability.
