Abstract:
For the development of elderly-friendly food, the physicochemical properties and preferences of cooked kkakdugi prepared with various blanching times were examined. As fermentation progressed, significant differences in samples were observed with overall decreasing trends of pH, reducing sugar, lightness (L), yellowness (b), and hardness. Titratable acidity, redness (a), and lactic acid increased during the storage time. The preference test showed that the sample blanched for 3 min (SK3) scored the highest in aroma, taste, texture, and overall acceptance. Overall, SK3 was the most preferred as cooked kkakdugi, which helps elderly people suffering from mastication and deglutition.

For input characteristics, the base-emitter voltage is varied, maintaining a constant collector-emitter voltage. This setup reveals a Shockley-type dependence of the collector current on...
Characteristics of JFET
The core of a JFET's operation is controlling drain current by modulating the gate-source voltage. When the drain and gate voltage are set to zero, the JFET exhibits no net current flow, representing a state of equilibrium. The drain current increases linearly as the...
Quality Control
Quality control helps track data, visualize trends, and identify variations, making it easier to detect deviations that may affect the accuracy of an analysis. One way to do this is by generating a quality control chart, which...
