An experimental equipment for measuring the ultrasonic transmission properties in liquids foods was developed. The equipment is based on pulse-echo technique, which can be used to measure the ultrasonic velocity, attenuation coefficient and specific acoustic impedance of liquid food samples. The relative error of the velocity is less than 0.5%.

An experimental equipment for measuring the ultrasonic transmission properties in liquids foods was developed. The equipment is based on pulse-echo technique, which can be used to measure the ultrasonic velocity, attenuation coefficient and specific acoustic impedance of liquid food samples. The relative error of the velocity is less than 0.5%. Measurements of attenuation coefficient and acoustic impedance are based on the ultrasonic transimission route and the acoustic reflection and transmission so that the accuracy is same fine. The equipment was used to research the relationship between ultrasonic velocity and raw cyrup concertration in malic juice. The result indicates that they have good correlation. Therefore, the equipment is practical and can be used for measurement of food quality.

研制了一个适用于液态食品超声波传播特性检测的装置,利用超声脉冲发射和接收测定液态食品的超声传播速度、声衰减和声阻抗。声速检测采用比较法,相对误差小于0.5%。利用声传播途径通过方程计算声衰减和声阻抗,计算中考虑了传播过程的声反射和声透射,结果具有一定的准确性。利用该装置研究发现苹果汁饮料中原果汁浓度与声速有良好的线性相关,具较好的实用性,可以应用于食品质量的超声检测。

The relationships between ultrasonic velocity and concentrations of glucose, fructose, sucrose, and mixed solution of glucose and sucrose were determined by experimental equipment based on ultrasonic transmission properties for liquid food quality measurement. The results indicate that the concentrations of glucose, fructose and sucrose are significantly correlated with ultrasonic velocity by quadratic polynomial (R~2>(0.997)). The binary and quadratic polynomials of ultrasonic velocity and...

The relationships between ultrasonic velocity and concentrations of glucose, fructose, sucrose, and mixed solution of glucose and sucrose were determined by experimental equipment based on ultrasonic transmission properties for liquid food quality measurement. The results indicate that the concentrations of glucose, fructose and sucrose are significantly correlated with ultrasonic velocity by quadratic polynomial (R~2>(0.997)). The binary and quadratic polynomials of ultrasonic velocity and the concentrations of compositions in mixed solution were obtained. The relationship between them was very closely correlated (P<0.0001). There was no significant difference (P≤0.05) in concentrations of reduced sugar, sucrose and total sugar determined by ultrasonics solved from the coupled equations of empirical equation and half-empirical equation, HPLC and traditional chemical methods in nine brands of fruit drinks. It was concluded that it should be possible to mearsure exactly different sugar concentrations in drinks by ultrasonics.

为研究果汁、饮料生产中糖浓度的在线快速测定技术,采用基于超声传播特性的液态食品质量检测装置,测定了纯果糖、葡萄糖、蔗糖溶液及葡萄糖—蔗糖混合溶液的糖组分浓度与声速的关系。结果表明:纯糖溶液中声速与浓度用二次方程回归呈极显著正相关(R2>0.9970);声速与混合溶液糖组分浓度关系密切,可用二元二次多项式拟合(P<0.0001);采用声速与浓度的经验公式和与理论结合的半经验公式组成方程组,对果汁饮料中的还原糖、蔗糖和总糖含量进行分析,与传统检测方法和高效液相色谱法(HPLC)的检测结果一致,其差异不显著(P≤0.05)。该研究表明超声检测技术有可能应用于果汁、饮料中糖组分浓度的检测。
