Abstract
SummaryBall‐milling is increasingly recognised as an efficient and environmentally friendly physical modification method in food processing. In this study, natural Litopenaeus vannamei protein (LVP) was subjected to ball‐milling treatment for 0, 5, 10, 15 and 20 min, respectively. Then, its structure and functional properties were investigated. Results indicated that proper ball‐milling treatment significantly enhanced the quality of LVP by influencing its structure. Specifically, ball‐milled LVP (BLVP) powder exhibited finer and brighter. BLVP subjected to 10 min demonstrated the highest solubility (22.80%), digestibility (64.50%) and foaming stability (93.69%), which were attributed to particle size and structure. BLVP processed for 15 min exhibited the highest oil holding capacity (1042.67%) and foaming capacity (17.11%), positively related to its surface hydrophobicity and sulfhydryl content. And its allergenicity decreased by 4.35%. These results provide a foundational framework for utilising ball‐milling to modify LVP, suggesting that this method may enhance the industrial applications of LVP.
