Good and Bad Classification of Mutton
Description
Capara hircus commonly known is a widely consumed in South Asia. It is valued for its High calorie content and high moisture level, making it suitable for healthy and Good. Mutton is a no source of dietary fiber, vitamins such as vitamin B12 and Vitamin B3 and essential minerals including potassium, magnesium, and iron, which support digestion, immunity, and cardiovascular health. The standard shelf life of Capra hircus depends mainly on storage conditions: At ambient (room) temperature (4 - 17 °C) 1–2 days . Rapid moisture loss, softening, and microbial spoilage occur due to high respiration rate. The Mutton showing deep red or light to dark red to with relatively smooth and intact skin represent better-preserved samples, although slight shrivelling and surface dullness suggest moisture loss and advancing senescence. In contrast, the severely deteriorated dull grey, brownish-red, or green exhibits discoloration, extensive fungal growth (white mycelium), tissue softening, and surface decay, which are typical symptoms of microbial spoilage and over-ripening. These changes reflect high respiration rate, enzymatic breakdown of tissues, and microbial invasion during prolonged storage. The image clearly demonstrates that after 2 days, Mutton stored under uncontrolled or suboptimal conditions becomes unacceptable for consumption, confirming its limited shelf life. Sample collection:- Fresh and mature Mutton of Capra hircus were collected from local markets of Malda town, West Bengal, India (24°59′N, 88°08′E), and the collection location was mapped using GPS coordinates. Immediately after procurement, the samples were sorted to remove damaged. The selected Mutton samples were first washed thoroughly with normal tap water to remove adhering soil and surface impurities. Digital images of the samples were captured using a smartphone (Realme C63 5g) operating on Android version 15. The device was equipped with an processor (MediaTak Dimensity 6300 GHz), 8 GB RAM, and 128 GB internal storage.Image acquisition was carried out daily for 1-2 consecutive days after purchase to monitor visual quality changes and shelf-life deterioration. Approximately 1000 images were captured per day, out of which 500 high-quality images per day were selected based on clarity, focus, and uniform illumination for further analysis. The image dataset was used to study progressive changes in color, texture, surface integrity, and microbial spoilage during storage. This systematic image acquisition protocol enabled continuous non-destructive monitoring of Mutton quality throughout the storage period. In this dataset, the bad image folder contains 500 images of Capra Hircus , and the good image folder also contains 500 images of Capra Hircus . Therefore, the total number of images in the dataset is 1000
