How Retort Packaging is Transforming the Ready To Eat Food Industry

While convenience food has been prevalent and popular in the developed world for years, its presence in the Indian market is comparatively recent. However, due to its many advantages, it is becoming increasingly popular. This type of food saves time and labour, has extended shelf life and is easily available – so with more and more couples going out to work, rise in income levels, change in food habits and lifestyles, and the Indian market for convenience food is growing in leaps and bounds.

Retort Processing is the preferred method of Ready-to-Eat food packaging, packing meals in durable pouches. Retort packaging is a unique form of stand up pouch used for cook-in-a-bag meals and sides, such as soups, rice, sauces, and pasta dishes. It maintains the shelf-life, texture and nutritive value of the food.

Ready-to-use retort pouches are flexible packages made from multiplayer plastic films with or without aluminum foil as one of the layers. Unlike the usual flexible packages, they are made of heat resistant plastics, thus making them suitable for processing at a temperature of around 121°C. The food-grade materials used to construct this type of packaging undergo a sterilization process that extends the shelf life of the product inside while boosting the durability of the package itself. After going through a retort machine, the food package is able to withstand high temperatures, making this the perfect solution for microwavable meals.

These retort pouches possess toughness and puncture resistance normally required for any flexible packaging. They can also withstand the rigours of handling and distribution. The material is heat sealable and has good barrier properties. Because of their strength, flexibility, and light weight, retorts pouches have become a widely used alternative to traditional methods for preserving and retailing food.

Indian food like palak paneer, dal fry, curry rice, pulav, vegetables Biryani etc. are retort processed because they are low acid food with moderate to large size particles; hence it is easy to remove oxygen from the head-space by gas flushing.

In India, 3-ply laminate consisting of PET/Al Foil/PP is commonly used for packaging of ready to eat retort packed food. The product packed in such laminates has a shelf-life of one year. The other materials generally used in retort pouch structure includes nylon, silica coated nylon, ethylene vinyl alcohol (EVOH) and polyvinyledene chloride (PVDC). These materials have high moisture barrier properties and are used successfully for packaging of ready-to-eat high moisture Indian food.
