中文摘要:采用电子舌技术结合主成分分析,以蔗糖为参比物,对5种不同组成的甜菊糖样品(RA95、RA97、RA99、RA/RB(90/10)、RA/RD(90/7)),进行了甜味特性评价研究,将评价结果与感官评价结果进行了对比。甜菊糖溶液质量浓度0.2~0.8g/L时,等同甜度的蔗糖溶液质量溶度为0.03~0.09g/mL,相对蔗糖甜度倍数为90~220,在口腔内的甜味持续时间为10~60s,质量浓度1.2g/L的5种甜菊糖溶液均呈现出明显苦味。电子舌可以准确识别5种不同类型甜菊糖样品,判别指数为100。在主成分分析得分图的PC1和PC2轴上,电子舌能够识别不同质量浓度的蔗糖和甜菊糖溶液,电子舌对相同质量浓度的甜菊糖溶液甜味强度识别结果从大到小依次为RA/RD(90/7)、RA95、RA/RB(90/10)和RA99、RA97、RA95,识别结果与感官评价结果一致。通过计算主成分得分图上的组间距离,电子舌判定3种RA系列甜菊糖与蔗糖的相似度最高的为RA99,其次为RA97和RA95。结果表明,电子舌技术在代替人工感官进行甜味评价方面有很好的应用前景。

Abstract:There is an urgent need in the food and beverages industry for evaluation of the sweetness taste by using a rapid and objective method. An electronic tongue was used to evaluate sweetness taste and compare different steviol glycosides (different compositions of rebaudioside A: RA95, RA97, RA99, RA/RB(90/10), RA/RD(90/7)). Five RA samples and sucrose used as a reference were analyzed by the electronic tongue and sensory panels. Sensory analysis demonstrated that the RA samples (0.2~0.8g/L) were 90~220 times sweeter than that of sucrose (0.03~0.09g/mL). The data obtained by electronic tongue was analyzed by principal component analysis (PCA). The extinction time of all RA samples ranged from 10s to more than 60s, and RA at 1.2g/L exhibited intense bitter taste. Five RA samples were successfully discriminated on the PCA score plot. Compared with sucrose at different concentrations, the intensity of sweetness taste of RA samples was ranked as: RA/RD(90/7)>RA95>RA/RB(90/10) and RA99>RA97>RA95. Based on euclidean distance on the PCA score plot, RA99 was revealed more similar taste than that of RA95 and RA97. The results showed that the electronic tongue analysis might be a useful method to complement sensory panels in evaluation of sweetness.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
