BPVI-013 IGNOU Solved Assignment 2026-27

BPVI-013 Solved Assignment: Milk Processing and Packaging (DDT 2023)

This structured solution aligns with the official IGNOU curriculum for BPVI-013, covering core blocks with verified answers for TMA submission. Below are key units from the syllabus, along with solved examples and FAQs.

1. Block-1: Milk Reception

This block focuses on the initial handling of raw milk, including quality checks, temperature control, and storage practices. Key topics include:

• Milk Quality Standards: Analysis of fat, SNF (Solid Not Fat), and microbial load as per IS 2894:2018.
• Temperature Regulation: Chilling milk to 4°C within 2 hours of collection to prevent spoilage.
• Storage Methods: Bulk storage tanks, silos, and refrigeration systems for large-scale operations.

2. Block-2: Processing of Milk

This block details standard processing techniques, including homogenization, pasteurization, and standardization. Solutions for TMA questions include:

• Homogenization: Reduction of fat globule size to 2 µm using high-pressure homogenizers (e.g., APV Gaulin).
• Pasteurization Methods: Comparison of HTST (72°C/15 sec) and UHT (135°C/2 sec) for shelf-life extension.
• Standardization: Adjusting fat-SNF ratio (e.g., 3.2% fat, 8.5% SNF for standard milk).

3. Block-3: Packaging and Distribution

Packaging solutions for milk products are analyzed here, including materials, aseptic packaging, and distribution logistics. Key points:

• Packaging Materials: Tetra Pak cartons (laminated paperboard + aluminum foil) for UHT milk.
• Aseptic Packaging: Sterilization of both product and container (e.g., Tetra Brik Aseptic).
• Distribution Chains: Cold chain maintenance (0–4°C) for perishable products.

4. Block-4: Cleaning and Sanitization

This block emphasizes hygiene protocols for equipment and processing areas. Sample TMA answers include:

• CIP Systems: Circulating alkaline/acid solutions (e.g., 0.2% NaOH) for tank cleaning.
• Sanitization Agents: Chlorine (50–100 ppm) or peracetic acid for surface disinfection.
• HACCP Compliance: Critical control points (CCPs) in cleaning schedules (e.g., post-production rinsing).
