Green Peas Processing and Preservation using IQF Technology

Categories

The green peas processing and preservation using IQF technology is a highly efficient and commercially viable method to retain the freshness, texture, color, and nutritional value of peas. IQF, or Individual Quick Freezing, is an advanced freezing technique used across the food processing industry, especially for fruits and vegetables. With rising global demand for ready-to-cook frozen foods and extended shelf life, IQF green peas have become a staple in retail chains, institutional kitchens, and food manufacturing units.

Importance of IQF in Green Pea Preservation

Fresh green peas are seasonal, perishable, and prone to rapid degradation due to moisture and enzyme activity. Traditional freezing techniques often result in clumping and loss of natural taste. The IQF technology for green peas processing and preservation overcomes these challenges by freezing each pea individually at ultra-low temperatures, ensuring optimal quality retention and long-term usability.

Key Benefits of IQF Green Peas

Non-sticky Texture: Each pea remains free-flowing, making portioning and cooking easier
Nutrient Retention: IQF locks in natural vitamins, minerals, and antioxidants
Extended Shelf Life: Frozen green peas can last up to 18 months in cold storage
Color and Freshness: Bright green color and natural taste are maintained
Reduced Waste: IQF peas are cleaned, sorted, and ready-to-use, minimizing consumer preparation time

These qualities make IQF green peas a preferred choice in the frozen food segment across domestic and export markets.

Raw Material Selection and Pre-processing

The production process starts with the selection of high-quality, mature but tender green peas. Key steps include:

Harvesting: Peas are harvested at the peak of maturity to ensure sweetness and softness
Sorting and Grading: Removal of damaged, overripe, or discolored peas
Washing: Multiple stages of washing to eliminate dirt, pesticides, and debris
Shelling: Using mechanical shellers to separate peas from pods
Blanching: Brief exposure to hot water or steam to deactivate enzymes and preserve color

Blanching is a crucial step before freezing, as it ensures microbial stability and enhances the freezing process.

IQF Freezing Process

The core of the preservation process is the IQF freezing system, which typically includes spiral or fluidized bed freezers. The process involves:

Feeding Blanched Peas: Cleaned and cooled peas are evenly spread on a mesh conveyor
Cold Air Blast: High-velocity cold air (–35°C to –40°C) rapidly freezes each pea
Individual Freezing: Unlike block freezing, each pea remains separate and does not stick together
Discharge and Packing: IQF-frozen peas are collected, weighed, and packed in LDPE or HDPE bags

The entire process takes just a few minutes, preserving all sensory and nutritional qualities of the peas.

Packaging and Storage

Proper packaging is essential to maintain product quality during transport and storage. Common packaging practices include:

Primary Packaging: 500g, 1kg, 5kg pouches made from food-grade, moisture-proof material
Secondary Packaging: Corrugated boxes for bulk handling
Storage Conditions: –18°C or lower in cold rooms with humidity control
Labeling: Includes batch number, manufacturing date, best-before date, and nutritional information

This packaging ensures the peas remain intact, fresh, and compliant with food safety standards.

Applications and Market Demand

IQF green peas are widely used in:

Ready-to-Eat Meals: Curries, soups, pulao, and pasta
Catering Services and Institutional Kitchens: Consistent quality and convenience
Food Processing Units: Used in frozen mixes, samosas, cutlets, and pre-packaged foods
Export Markets: High demand in Gulf countries, Europe, USA, and Southeast Asia

The IQF frozen vegetable market is expected to grow at a CAGR of over 5% globally, with green peas as one of the top-selling products.

Machinery and Plant Setup Requirements

To start a green peas IQF processing business, the following machinery and infrastructure are needed:

Green Pea Sheller
Sorting and Grading Lines
Blanching Unit (Steam/Water)
Cooling Conveyor or Hydro Cooler
IQF Freezer (Tunnel/Spiral Type)
Weighing and Packaging Machines
Cold Storage Units

A medium-scale plant with a capacity of 1–2 tons per hour can be set up with an investment of ?1.5–3 crores, depending on automation and land costs.

Licensing and Compliance

To operate legally and ensure food safety, the following approvals are require:

FSSAI License – Mandatory for food processing units
Pollution Control Board Clearance
Factory License and Fire Safety Certificate
Cold Chain Infrastructure Registration
Export Certification (APEDA) – If targeting international markets

In addition, compliance with ISO 22000, HACCP, and BRC standards enhances credibility and market access.

Profitability and Business Potential

IQF green peas offer a high return on investment due to:

Year-round Demand despite seasonal harvesting
Value Addition through pre-processing and freezing
Bulk Orders from retail chains, hotels, airlines, and exporters
Scalability to other vegetables like carrots, sweet corn, beans, etc.

With a shelf life of over a year and efficient cold chain management, entrepreneurs can cater to both B2B and B2C segments profitably.

Environmental and Sustainability Considerations

Modern IQF plants are increasingly adopting:

Energy-efficient Freezers
Water Recycling Systems in washing and blanching units
Solar Power Integration for cold storage
Zero Waste Policies by converting pea pods into animal feed or compost

These efforts not only reduce operational costs but also align with global sustainability goals.

Conclusion

The green peas processing and preservation using IQF technology represents a smart investment for food entrepreneurs, agro-processors, and exporters. It combines the advantages of high product quality, long shelf life, and versatile applications across industries. With growing demand for frozen vegetables and government support for cold chain infrastructure, this business promises strong growth, reliable profits, and wide market reach.
