In this study, the effects of Opuntia dillenii polysaccharide (ODP) at different concentrations (1%, 3% and 5% wet materials) on the gel properties of Trichiurus lepturus myofibrillar proteins were investigated. ODP was prepared by hot water extraction, consisted of arabinose, xylose, fructose, glucose, galacturonic acid and rhamnose and its molecular weight was 106 kDa. The addition of ODP increased the water holding capacity, sulfhydryl content adhesiveness, cohesiveness, elasticity and overall likeness of T. lepturus myofibrillar proteins gel. However, a high dose (5% wet materials) of ODP could not further increase or decrease its efficiency compared with moderate dose (3% wet materials). Consequently, the addition of ODP increased the gel properties of T. lepturus myofibrillar protein gel and could be used as a myofibrillar protein gel supplement.
在这项研究中，研究了不同浓度（1%、3%和 5%湿材料）的仙人掌多糖（ODP）对鲷鱼肌原纤维蛋白凝胶特性的影响。ODP 通过热水提取得到，由阿拉伯糖、木糖、果糖、葡萄糖、半乳糖醛酸和鼠李糖组成，分子量为 106kDa。添加 ODP 增加了水保持能力、巯基含量、黏附性、内聚性、弹性和鲷鱼肌原纤维蛋白凝胶的整体相似性。然而，高剂量（5%湿材料）的 ODP 与中剂量（3%湿材料）相比，不能进一步增加或降低其效率。因此，ODP 的添加增加了鲷鱼肌原纤维蛋白凝胶的凝胶特性，可作为肌原纤维蛋白凝胶的补充剂。
