This section discusses the classification of processed foods by examining various categories such as minimally processed, preserved, manufactured, formulated, food derivatives, functional foods, and medical foods. Each classification emphasizes different processing techniques and their relevance in food technology.
Detailed
Processed Foods Classification
Processed foods can be categorized according to the extent and type of processing they undergo. Understanding these classifications is crucial in the field of food technology as it reflects the methods used to extend shelf life, enhance safety, and fulfill consumer demands for convenience.
- Minimally Processed Foods: These undergo the least alteration to retain freshness and quality, involving processes such as cleaning and refrigeration. Examples include fresh-cut fruits and vegetables.
- Preserved Foods: These retain the character of the original product but undergo preservation methods such as freezing or dehydration, such as frozen vegetables or dried fruits.
- Manufactured Foods: In these items, the original properties are altered through preservation methods alongside the use of ingredients like sugar and salt. Examples include pickles and jams.
- Formulated Foods: These are complex food products created by mixing multiple ingredients, resulting in items like bread and ice cream.
- Food Derivatives: Components extracted from raw materials follow purification processes, such as oils extracted from oilseeds.
- Functional Foods: Foods designed to provide health benefits beyond basic nutrition, like probiotics.
-
Medical Foods: Meant for dietary management of health conditions, such as low-sodium salt for heart health.
Each classification aids in understanding consumer needs and helps the food industry in developing targeted products.

- Minimally processed foods: These are processed as little as possible in order to retain the quality of fresh foods. Generally, the processes used are cleaning, trimming, shelling, cutting, slicing, and storage at low refrigeration temperatures.
Detailed Explanation
Minimally processed foods undergo very few changes from their raw state to ensure they retain their freshness and quality. Common techniques include cleaning and cutting vegetables or fruits, which helps to prepare them for cooking or eating while ensuring they stay as natural as possible. These foods require refrigeration to maintain their quality, preventing spoilage.
Examples & Analogies
Think about pre-cut vegetables you might buy at a grocery store. They are clean and ready to use, maintaining their original flavor and nutrients, similar to how you would prepare fresh veggies at home before cooking.
Preserved Foods

- Preserved foods: The methods of preservation used do not change the character of the product substantially e.g., frozen peas and frozen vegetables, dehydrated peas, dehydrated vegetables, canned fruits and vegetables.
Detailed Explanation
Preserved foods are treated in ways that extend their shelf life while keeping much of their original flavor and texture intact. Techniques like freezing or dehydrating minimize nutrient loss and prevent spoilage, allowing these foods to be available long after they are harvested.
Examples & Analogies
Consider frozen peas. They are harvested at their peak and quickly frozen, preserving their taste and nutrients much like capturing a moment in time. When you cook them later, they taste fresh, despite being stored for months.
Manufactured Foods

- Manufactured foods: In such products, the original characteristics of the raw products are lost, and some basic methods of preservation are used, often using various ingredients such as salt, sugar, oil, or even chemical preservatives. Examples are pickles, jams, marmalades, squashes, papads, wadis.
Detailed Explanation
Manufactured foods undergo significant changes from their raw ingredients, often resulting in a new product that may have different textures and flavors. These foods often include preservatives to enhance their shelf life, making them suitable for longer storage. The transformation involves the addition of other ingredients to achieve desired taste and consistency.
Examples & Analogies
Think about fruit jam. Fresh fruit gets cooked down with sugar and preservatives to create a spreadable product. Itβs quite different from the original fruit, but it offers convenience and a longer shelf life, allowing us to enjoy those flavors year-round.
Formulated Foods

- Formulated foods: These are products prepared by mixing and processing individual ingredients to result in relatively shelf-stable food products such as bread, biscuits, ice cream, cakes, kulfi.
Detailed Explanation
Formulated foods are created by combining various ingredients in specific proportions. The aim is to achieve a product that is both durable and enjoyable to eat. The formulation process can involve complex methods to ensure the final product has the right texture, flavor, and shelf stability.
Examples & Analogies
Imagine baking a cake. You combine flour, sugar, eggs, and other ingredients, mixing them in just the right way to create a delicious dessert that can be kept for days. This careful blending and the use of stabilizers allow the cake to maintain its quality during storage.
Food Derivatives

- Food derivatives: In industry, components of foods may be obtained from the raw product through purification, e.g., sugar from sugarcane or oil from oil seeds. In some cases, the derivative or the component may be processed further, e.g., conversion of oil to vanaspati (the process is called hydrogenation).
Detailed Explanation
Food derivatives are products that are extracted and refined from raw materials. This can involve several steps to purify and process the original components into usable ingredients for various applications in the food industry. For example, extracting oil from seeds involves pressing and refining the oil to remove impurities.
Examples & Analogies
Think about how olive oil is made. Olives are harvested, crushed, and then the oil is extracted, refined, and bottled. Consumers can then use this versatile ingredient in many dishes or for cooking.
