Food items are being processed for various reasons. Since times immemorial, grains have been dried after harvest to increase their shelf life. Initially, foods were processed primarily to improve digestibility, palatability and to ensure a continuous supply. In India, pickles, murabbas and papads are examples of preserved products made from certain vegetables/fruits/grains.

Detailed Explanation

This chunk explains the historical context of food processing. Humans have always processed food to make it last longer or to enhance its taste and digestibility. For example, when grains are dried, it prevents them from spoiling quickly. In India, traditional foods like pickles and murabbas show how various fruits and vegetables are preserved to enjoy them over time.

Examples & Analogies

Think of your favorite fruit jam. When you see it in a jar on the shelf, it’s the result of fruit processing that not only makes the fruit last longer but also enhances its flavors. Just like with dried grains or pickles, processing helps in enjoying seasonal products all year round.

Modern Consumer Demands

With the passage of time, improved transportation, communication and increasing industrialization have led to more diverse consumer demands for fresh and organic foods, safer and healthier options, and products with adequate shelf life.

Detailed Explanation

This chunk highlights how advancements in society have changed consumer preferences. Today, people are not just looking for food that is safe to eat; they also desire options that are fresh, organic, and healthier. As a result, food processing scientists are challenged to develop products that meet these specific demands.

Examples & Analogies

Consider how grocery shopping has evolved. Years ago, most people bought just what was fresh and in season. Now, you can find fresh organic fruits and vegetables from different parts of the world at your local store. This demand for diversity influences food processing techniques.

India has progressed from an agro-deficit to an agro-surplus country creating the need for storage and processing of agricultural and horticultural produce, emerging as a major producer of processed foods.

Detailed Explanation

This chunk focuses on India's transition in the agricultural sector. As the country became able to produce more food than it consumed, there arose a crucial need for systems that can store and process this surplus to prevent waste and ensure availability.

Examples & Analogies

Think about how much food is grown in your local area. With more food available, processing practices become critical to avoid spoilage and ensure that surplus fruits and vegetables reach consumers in a consumable format.
