Discuss about the processing of "ready to cook" chicken with a flow diagram and BIS grading for dressed chicken.

Processing of Ready-to-Cook Chicken

Ready-to-cook chicken involves minimal processing to retain the natural flavor and nutritional value while providing convenience. The process typically involves several key steps, as illustrated in the flow diagram below.

Detailed Steps:

• Receiving and Inspection: Live chickens are received and subjected to a thorough inspection to ensure they are healthy and free from disease.
• Slaughtering and Bleeding: Humane slaughtering practices are followed, and complete bleeding is ensured.
• Scalding and De-feathering: Feathers are removed mechanically after scalding the carcass in hot water.
• Evisceration: Internal organs are removed, and the carcass is thoroughly cleaned.
• Chilling: The carcass is rapidly chilled to reduce bacterial load and preserve freshness. This is typically done at temperatures close to 0°C.
• Cutting and Portioning: The carcass is cut into desired portions (e.g., breasts, legs, thighs).
• Marination (Optional): RTC products often undergo marination with various spices and flavorings. This enhances taste and acts as a preservative.
• Packaging: Portioned chicken is packaged in modified atmosphere packaging (MAP) to extend shelf life and maintain freshness. MAP typically involves a mixture of gases like carbon dioxide, nitrogen, and oxygen.
• Freezing/Chilling: The packaged product is either frozen or chilled, depending on the desired shelf life.

BIS Grading for Dressed Chicken

The Bureau of Indian Standards (BIS) has established IS 17274:2019 – “Dressed Chicken – Specification” to ensure the quality and safety of dressed chicken available to consumers. The grading system is based on a point system, evaluating various parameters.

Grading Criteria

Parameter	Acceptable Range/Limit	Points
Carcass Cleanliness	Minimal contamination	5
Odor	Fresh and normal	5
Color	Normal pinkish-red	5
Texture	Firm and elastic	5
Body Weight	As per specification	5
Moisture Loss	Not more than 3%	5
pH Value	5.8 – 6.2	5

Grade Designation:

• Superior Grade: 35-40 points
• Good Grade: 30-34 points
• Passable Grade: 25-29 points
• Below Passable Grade: Less than 25 points (Not acceptable for sale)

The BIS certification mark indicates that the dressed chicken meets the specified quality and safety standards. This certification is voluntary, but increasingly sought after by processors to build consumer trust and access premium markets.

definition Modified Atmosphere Packaging (MAP) A food packaging technique where the atmosphere inside a package is altered to extend the shelf life and preserve the freshness of the food product. It typically involves altering the gas mixture to inhibit spoilage organisms. statistic The Indian poultry sector contributes significantly to the nation's economy, accounting for approximately 6% of the total agricultural GDP (as of 2023 data). National Livestock Mission example Amul, a leading dairy cooperative in India, has diversified into RTC chicken products, showcasing the growing popularity and market potential of this segment. Their products adhere to stringent quality standards. faq What is the difference between chilled and frozen RTC chicken? Chilled RTC chicken has a shorter shelf life and requires refrigeration. Frozen RTC chicken has a longer shelf life due to the freezing process, but may require a slightly longer cooking time. scheme National Livestock Mission A scheme launched by the Government of India to promote livestock development, including poultry farming, by providing infrastructure support, disease control measures, and market linkages. 2014 case-study A study in Tamil Nadu revealed that poultry farms obtaining BIS certification experienced a 15-20% increase in sales and improved access to export markets due to enhanced consumer confidence and adherence to international quality standards. However, initial certification costs posed a challenge for smaller farms. Increased sales, improved market access, but initial cost barrier for smaller farms. definition Evisceration The process of removing the internal organs (viscera) from a slaughtered animal, typically poultry, as part of the processing procedure. statistic India is one of the largest producers of poultry meat in the world, with an estimated annual production of over 4.8 million tonnes (as of 2023).
