Research on formula establishment to produce nutritional seasoning powder from pangasius by-product hydrolysed protein

Abstract

The processing of pangasius fish has produced a number of by-products with economic and biological value such as heads, bones, and fins, but these products have not been fully utilised. The hydrolysed protein powder from pangasius by-products has a high nutritional content, attractive taste and mainly used as the raw material in the production of some value-added food products. The purpose of this study was to develop a formula to create seasoning products from protein powder hydrolysed pangasius by-products. The main ingredients such as pangasius protein powder, starch, basic spices (salt, sugar, onion powder, ginger, pepper, etc.) were studied and selected in the recipe for seasoning powder. In which, the research process to determine the ratio of the main ingredients was done with 25-45% protein powder from pangasius by-products combined with 20-35% modified starch; 16-24% salt; 5-20% sugar; 0.5-2% spice mixture of onion powder, ginger powder, pepper powder. Product quality was assessed through sensory criteria, protein content, carbohydrates, etc. Research results had built a formula for producing nutritional seasoning products from protein powder hydrolysed pangasius by-products with protein content 18-22%, carbohydrates 30-33%, salt content 18-20%, moisture content ≤10%, and food safety criteria meet the requirements according to current regulations.
