摘要
以凝胶强度和质构特性(TPA)为指标,对罗非鱼的超高压凝胶化工艺进行了优化。优选方案为:样品初温4℃,在300MPa下保压处理20min,随后再用90℃热处理30min。经验证,该工艺明显优于相应的单纯加热(二段法)和单纯加压(300MPa/20min)处理,预示超高压适当结合热处理有助于协同发挥压力和热力的各自优势。
Gel strength and Texture Proile Analysis (TPA) properties were chosen as indicators and the processing of ultra - high - pressure - gelling for Tilapia surimi was modified. The optimization condition is described as follows: the samples with original temperature of 4℃ were pressurized at 300MPa for 20rain, and then heated at 90℃ for 30rain. Compared with the samples gelatinized by pure heating (40℃/30min plus 90℃/30min) and pure pressurizing ( 300MPa/20min), the modified processing shows better effects on the Tilapia surimi gelling properties, predicting the dominance of the co -operation of pressure with heat.
