摘要: 以粘合强度为指标,研究了大豆分离蛋白(Soybean protein isolate,SPI)胶的pH、浓度、固化时间对猪扇骨粘合性能的影响,并通过正交实验优化了其具有最佳粘合性能的工艺参数。结果表明:大豆分离蛋白胶的浓度、pH(仅6.5与8.5时)、固化时间(仅12 h与36 h时)对猪扇骨的粘合强度的影响有显著性差异(P<0.05)。进一步的研究表明大豆分离蛋白胶对猪扇骨具有最佳粘合性能的工艺参数为:浓度10%,pH 6.5,固化时间48h,此时的粘合强度达到380KPa。本研究表明SPI胶具有潜在的医用黏合剂的应用价值。

Abstract: The purpose of this study was to explore the influence of pH,concentration and curing time on the adhesive strength of soybean protein isolate (SPI) onto porcine bones.SPI adhesive was used to bond porcine bones and its bonding performance parameters were optimized through orthogonal experiments.The results of single factor test showed that SPI concentration,pH (at 6.5 and 8.5) and curing time (at 12 h and 36 h) had significant effects on the adhesive strength (P<0.05).The results of orthogonal experiments indicated that the optimal bonding performance of the adhesive was obtained at SPI concentration of 10%,pH of 6.5 and curing time of 48 h.Under the optimal condition the bonding strength of the SPI adhesive was 380 KPa,suggesting that SPI has a potential to be utilized as an adhesive in medical fields.

Key words: soybean protein isolate, bone, adhesive strength
