Development of High Dietary Fiber Cereal Bar as Emergency Food Product and The Chemical-Microbiological Properties and Nutritional Content

Background: Dietary fiber is essential for maintaining digestive health, especially during emergencies with limited food availability. Objectives: To analyze the chemical, microbiological, and nutritional properties of high-fiber cereal bars designed as emergency food. Methods: This study used an experimental design. The cereal bars were made from rice crisps and oats and tested based on chemical and microbiological parameters. Chemical analysis included dietary fiber, carbohydrates, protein, fat, minerals, and vitamins while the microbiological analysis covered total plate count (TPC) and detection of pathogenic bacteria such as Escherichia coli, Salmonella, and Staphylococcus aureus in accordance with food safety standards from the Indonesian Food and Drug Authority (BPOM). The testing was conducted from November 3–15, 2023, at PT Saraswanti Indo Genetech laboratory, Indonesia. Results: The test showed that the mixed berry cereal bar contained 9.43% dietary fiber, exceeding BPOM standards. The product was free from heavy metal contamination (arsenic, cadmium, mercury, lead, and tin) and showed no trans fats. Microbiological tests confirmed that the product was safe from pathogenic microbes, with total plate count (TPC) and Enterobacteriaceae within safe limits. The product also did not contain Salmonella or Staphylococcus aureus. Conclusions: This high-fiber cereal bar meets strict food safety and nutritional standards, making it suitable for development as emergency food. Its high fiber content and lack of harmful contaminants make it safe and nutritious for disaster victims. Continued testing and development with diverse flavors and formulations are recommended to improve acceptance across age groups in emergency situations.
