不同预处理对高温热空气油炸鱿鱼片品质影响研究

以冷冻鱿鱼为原料,通过水分测定、质构测定、色差测定、扫描电镜观察等指标检测,探究了高温热空气油炸加工鱿鱼脆片工艺中脱水前的不同预处理方式对油炸鱿鱼片品质影响,并确定最佳预处理方式。结果表明,鱿鱼脱水前最佳预处理方式为在50℃,pH值7.0的条件下,将鱿鱼置于质量分数为1%的木瓜蛋白酶溶液中浸泡30min,然后在沸水中煮2min;经过加酶预处理后制得的油炸鱿鱼片具有有酥脆的口感,且使油炸鱿鱼片硬度适中,减少了油腻感。

鱿鱼脆片的加工工艺研究

以鱿鱼为原材料,通过水分含量、质构参数和感官评分等指标测定,探究经真空冷冻干燥后的鱿鱼分别在常压油炸和高温热空气油炸条件下,油炸温度和油炸时间对鱿鱼脆片品质的影响,并确定鱿鱼脆片最佳加工工艺。试验结果表明,经过真空冷冻干燥处理后的鱿鱼再油炸处理可以得到酥脆的鱿鱼片,且鱿鱼脆片最佳加工工艺为:鱿鱼经过前处理、调味、蛋白酶处理、预冻和冻干后,在油炸温度为160℃条件下进行高温热空气油炸,油炸时间为4 min。此工艺制得的鱿鱼脆片有油炸风味,组织表面紧密收缩,少量褐变,硬度较小,较酥脆,无油腻感。

Effects of Different Processing Methods on the Qualityof Squid Chips

Taking squid as raw material, the effects of frying temperature and frying time on the quality of squid chips were studied under the conditions of normal pressure frying and high-temperature hot-air frying respectively. And the best processing technology of squid chips was determined. The results showed that crispy squid chips can be obtained by frying the squid after vacuum freeze-drying, and the best processing technology of squid chips is to treat the material by hot air drying at 160℃ for 4 min after pretreatment, seasoning, protease treatment, pre-freezing and freeze-drying. The squid chips made by this technology have a flavor of frying, tightly-shrunken surface tissue, a little browning, less hardness, crispness and no greasy taste.
