Description
Adulteration Detection of Milk Powder with All Purpose Flour (Maida) Location: Mahila, Malda, West Bengal, India Time: 10 AM to 5 PM About Milk Powder: Milk powder is a dairy product made by evaporating milk to dryness, which increases its shelf life and makes it easier to store and transport. It contains essential nutrients like proteins, calcium, and vitamins, and is widely used in beverages, baking, and confectionery products. High-quality milk powder should be pure, free from contaminants, and have a characteristic milky taste. About All Purpose Flour (Maida): All-purpose (AP) flour is a milled wheat flour with a moderate protein content (9-12%) suitable for various culinary applications, such as making breads, cakes, and thickening sauces. Adulteration Concern: All Purpose Flour (Maida) is sometimes fraudulently mixed into Milk Powder to increase the product’s weight and profits. This adulteration significantly lowers the nutritional value of the milk powder and poses serious health risks such as digestive discomfort, gastrointestinal issues, and other harmful diseases. --- Mobile Details: Mobile Name: Moto G85 Camera Sensor: Sony LYT600 with OIS (Optical Image Stabilization) RAM & Storage: 4 GB RAM, 128 GB ROM Camera: Rear Camera – Dual; Front Camera – 16 MP Display: 6.5-inch Full HD+ Battery: 5000 mAh --- Process: 1. Sample Preparation: First, buy pure milk powder and all-purpose flour (maida) from the local market. 2. Precautions: Wear masks and gloves, as fine powders can cause respiratory discomfort. Conduct the experiment in a clean, dry place with proper ventilation. 3. Weighing Samples: Measure pure milk powder using a precision weighing balance. Divide the sample into 20 equal portions. 4. Adulteration Proportions: Prepare adulterated samples by mixing milk powder with All Purpose Flour at different proportions by weight: 0% (Pure milk powder), 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, and 100% (pure flour). 5. Background Setup: Use two types of backgrounds: White background Black background (For clearer identification of adulteration levels during image analysis). 6. Sample Display: On a white paper and black paper (210 mm x 297 mm, 80 gsm), draw 20 equal-sized cells. Spread each sample thinly and evenly within the cells. 7. Image Capture: Click photos of each sample using Moto G85 (Sony LYT600 sensor with OIS) for high clarity and stability. For each background, 12 sets of samples are prepared: 1 set of 100% pure milk powder 1 set of 100% All Purpose Flour 10 sets of adulterated samples (with varying proportions of flour). 8. Total Image Count: Each background sheet: 12 sets × 20 samples = 240 images. Two backgrounds → Total images = 240 × 2 = 480 images.
