| Summary: | 10%, 20%, 30%, and 40% rice flour (for each PSD flour) were able to detect differences in the different rice slurries. absorbed by the slurry and a portion reflected to a receiving An ultrasonic longitudinal wave was transmitted through the characteristics were placed on the top surface of the sensor. concentration. The values for flow behavior index follow the continuous, longitudinal waves at 500 kHZ, 1 MHz, and 2 MHz. detect the differences between the PSD flours (P=0.0739). The emerging issue of today. Many food processing industries every 10 seconds. Results indicated that the sensors were for power law Theological parameters and for viscoelastic in the food processing plant to minimize batch methods of measured Theological parameters. The sensors were able to mixed with 4% Carboxy-methylcellulose solutions and tested parameters with the Haake CV20 rheometer. Two repetitions particle size distributions (PSD). Concentrations of 5%, plants. This research describes the development of a poorly processed foods or production delays in processing rely on batch methods to inspect food quality. These same trend. The sensor voltage values correlated to the sensor and into the sample where a portion of the energy was slurries and dough. This inexpensive sensor can be applied Slurries of different concentration and particle small PSD flour created slurries of significantly higher techniques yield results which are delayed in responding to The development of new sensors to monitor food quality is an the dynamic systems during food processing, resulting in The output voltage from the receiving transducer was recorded The sensor output voltage decreased with increased rice flour Theological testing. Rice was milled to two different to measure the relative acoustic impedance of rice slurries. transducer. The samples were subjected for ten minutes to ultrasonic sensor to measure viscoelastic properties of rice viscosities than the large PSD slurries. were completed for each treatment. Sensors were fabricated |
