Quality Control and Quality Testing of Final Product of Chocolate-Flavored Pasteurized Milk at CV Cita Nasional
Keywords:
quality control, fat content, pasteurized milk, quality control, statistical analysis, CV Cita NasionalAbstract
CV Cita Nasional is a dairy processing company that produces pasteurized milk and yogurt in various flavors, with chocolate being one of its flagship products. Pasteurized milk has a relatively short shelf life because the heating process does not completely sterilize the milk, making quality control of the final product essential. The purpose of this quality control is to ensure that each final product of pasteurized milk meets both the company’s internal quality standards and the national regulations SNI 01-3591-1995. Quality control is carried out by monitoring physicochemical parameters, including pH, fat content, total solids, and sweetness level (Brix). Testing was conducted routinely for 23 consecutive days on the final product of chocolate-flavored pasteurized milk. The test data were then analyzed using statistical control methods to evaluate the stability of the quality system and identify deviations from established standards. The results of quality control and quality testing indicated that there was one pH sample, all fat content values, and Brix values that did not comply with the internal standards. Statistical control analysis showed that the product quality was relatively stable; however, improvements are still needed because some values were below the company’s internal quality standards.
