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

Food processing has a long history, starting with simple preservation techniques. Early civilizations would dry or preserve grains after harvest to ensure they could be stored for longer durations. This basic method was developed further, and today we have a variety of processed foods. In India, for example, traditional foods such as pickles and papads demonstrate how people have preserved foods for flavor and longer shelf life.

Examples & Analogies

Think about how you might save leftovers from dinner by refrigerating them. Similarly, our ancestors found ways to keep foods fresh longer, which allowed them to be used later, like making pickles from seasonal fruits and vegetables.

Evolving Consumer Demands

With passage of time, improved transportation, communication and increasing industrialisation, the needs of consumers have become more diverse and there is now increasing demand for ‘fresh’ and ‘organic’ foods, ‘safer and healthier’ foods and foods with adequate shelf life.

Detailed Explanation

As transportation and industrial capabilities improved, consumer preferences evolved. People began to seek out foods that are not only fresh and healthy but also have longer shelf lives without compromising quality. This shift has led to the creation of new processing technologies that cater to these demands, ensuring that food remains nutritious while being convenient for modern lifestyles.

Examples & Analogies

Consider how grocery stores today offer organic food sections. This change reflects the growing consumer awareness of health and nutrition, paralleling how producers adapt to meet these new preferences.

India has progressed from an agro-deficit to an agro-surplus country creating need for storage and processing of agricultural and horticultural produce. Indian food industry has thus emerged as a major producer of processed foods and ranks fifth in terms of size, contributing nearly 6 percent of GDP.

Detailed Explanation

The development of food processing technology in India has transformed the country’s agricultural landscape from one of food scarcity to abundance. This shift has increased the need for sophisticated techniques to store, process, and market agricultural products, helping India rank among the largest producers of processed foods globally. The food industry plays a critical role in the economy, highlighting the importance of food technology in modern India.

Examples & Analogies

Think of it like how a local farm changes once it starts processing its products. Instead of just selling raw vegetables, the farm starts making and selling sauces, pickles, or frozen foods, thus increasing its income and market reach, while also providing jobs in the community.

Health and Nutrition in Food Processing

Food fortification is done by adding the nutrient that is lacking in the foodstuffs or condiments to ensure that minimum dietary requirements are met. Some examples are iodised salt, folic acid added to flour, vitamin A and D added to milk and oils/fats.

Detailed Explanation

Food fortification is an important aspect of food processing aimed at addressing common nutritional deficiencies in populations. By adding essential vitamins and minerals to staple foods, we improve public health outcomes. For example, iodising salt helps prevent iodine deficiency, which is crucial for thyroid function.

Examples & Analogies

Just like how we might take vitamin supplements to ensure we're getting enough nutrients, food fortification serves a similar purpose on a larger scale, ensuring whole communities receive the nutrients they need through everyday foods.

Consumer Expectations

Consumer perceptions about food have changed. The demand for foods free of chemicals, pesticides and preservatives, yet having a longer shelf life and retaining their natural flavour and appearance, is rapidly increasing.

Detailed Explanation

Modern consumers are becoming more aware of the ingredients in their food. They want options that are natural and healthy but also convenient. This growing awareness demands that food processing technologies evolve to ensure products meet these expectations without sacrificing quality or safety.

Examples & Analogies

Similar to how you might choose a product with 'all-natural' on its label over a highly processed option, consumers today prefer to navigate towards transparent food processing methods that highlight the benefits of natural ingredients.
