摘要:

为研究膨化虾片的最佳加工工艺条件,以木薯淀粉、南美白对虾为原料,采用单因素试验和响应面优化法研究蒸煮时间、老化时间、切片厚度、干燥时间、油炸温度对产品膨化度和感官评分的影响。结果表明,膨化虾片的最佳加工工艺为: 蒸煮时间33.82 min,老化时间24.72 h,切片厚度1~2 mm,60 ℃下鼓风干燥4.95 h,180 ℃油炸。在此条件下,膨化虾片酥脆可口、咸鲜味浓厚、膨化效果好、蛋白质含量高且含油率合理。风味剖面感官分析表明,番茄味膨化虾片的风味评价较好,酥脆感和油脂香得分较高,甜味适中,但略有油腻感,在控油方面还有改进空间。扫描电镜分析结果证实,油炸前虾片的空隙、孔容、孔径较大,因此油炸后产品酥脆可口。气相色谱-质谱联用(gas chromatography-mass spectrometry, GC-MS)分析得出,油炸前虾片中风味物质有21种,萜烯类、醇类、醛类物质相对含量占总香气组分的比重较大;油炸后有20种,酸类、酯类、醛类物质相对含量占总香气组分的比重较大。以上结果为番茄味膨化虾片的产业化应用提供了试验及理论基础。

Abstract:

In order to study the optimum processing conditions of puffed shrimp slices,cassava starch and Penaeusvannamei were used as raw materials. The effects of cooking time, aging time, slice thickness, drying time and frying temperature on the expansion degree and sensory score of the products were studied by single factor test and response surface test. The results showed that optimal processing technology of puffed shrimp slices was determined as follows: cooking time for 33.82 min, aging at 4 ℃ for 24.72 h, sliced into 1~2 mm slices, air dried at 60 ℃ for 4.95 h, and fried at 180 ℃. Under these conditions, the puffed shrimp slices were crispy and delicious, with strong salty taste, good puffing effect, high protein content and reasonable oil content. The sensory analysis of flavor profile showed that the flavor of puffed shrimp slices was evaluated well, with high scores of crispness and fat aroma, moderate sweetness, but slightly greasy, and there was still room for improvement in oil control. Scanning electron microscope analysis confirmed that before frying, the gap, pore volume and pore diameter of shrimp slices were large, so the fried products were crisp and delicious. 21 kinds of flavor compounds in potato chips before frying and 20 kinds after frying were analyzed by gas chromatography-mass spectrometry (GC-MS). The result of scanning electron microscopy showed that before frying, the relative content of terpenes, alcohols and aldehydes accounted for a large proportion of the total aroma components, while after frying, the relative content of acids, esters and aldehydes accounted for a large proportion of the total aroma components. The above results provided an experimental and theoretical basis for the industrial application of puffed shrimp slices.
