Food has been an essential commodity for humans for thousands of years. As humans, we consume food in all forms. Our prehistoric ancestors who discovered fire also found a way to cook food using the fire. It’s interesting to see how food processing evolved from the early fires to the sophisticated methods we see today. 

According to a report, “The Indian food industry with a size of 61 billion US dollars, ranks 5th in terms of size, contributes nearly 6% of GDP, 13% of Indian exports, and involves 6% of total industrial investment in the country. Besides, it is estimated to grow at the rate of 20% of which the processed food segment accounts for 25%. “

Let’s start with the basics. What exactly is food processing? 

Food processing is a technique used to transform raw ingredients into finished and semi-finished products. It involves a series of processes, with the help of sophisticated equipment, to convert these raw ingredients into edible and more palatable foods and beverages. Food processing is carried out to make food safe for consumption, improve taste, last long by increasing shelf-life and add nutrition. 

What are the categories of processed foods? 

The categories are as follows: 

1) Minimally processed foods

This process requires minimal interference and is done only to maintain the original quality of fresh foods. It involves only cleaning, trimming, slicing, and storage at low temperatures. 

Example: Cut fruits, Roasted Nuts 

2) Preserved foods 

All foods that are refrigerated, canned, and dried come under the category of ‘preserved foods’. This process is undertaken to slow down the spoilage of food and prevent any illnesses from unwanted microorganisms. 

Example: Canned food

3) Manufactured Foods 

These foods are processed using added ingredients that alter their basic, natural state. This process requires the use of natural or chemical preservatives. 

Example: Fruit jams, pickles, papads. 

4) Formulated Foods 

These foods are a complex mixture of various ingredients resulting in the formation of a new food product much different from its original natural form. 

Example: Bread, biscuits, ice-cream, cakes 

5) Food derivatives 

This process involves obtaining certain foods using a method. 

Example: i) Sugar is obtained from sugarcane using the method of purification. 

  1. ii) Conversion of oil to vanaspati using the method of hydrogenation. 

6) Functional foods 

These foods are made for the sole purpose of providing a beneficial effect on human health. 

Example: Probiotic products such as yogurt, milk, etc. 

7) Medical Foods 

These food products are manufactured for a niche part of the society that suffers from intolerance and allergies to certain foods. 

Example: Low sodium salt, Lactose-free milk. 

Food processing equipment plays an important role in carrying out various food processes. Let’s understand the various kind of food processing equipment listed below: 

1) Preparation Equipment 

This equipment is used by food manufacturers to remove foreign matter and contaminants to avoid damaging the food or other food processing equipment in the supply chain. 

The following processes are carried out by Food preparation equipment: 

  • Cleaning 
  • Grading 
  • Peeling/Skinning 
  • Sorting 

2) Mechanical Processing Equipment 

Mechanical processing operations are undertaken to reduce, enlarge, homogenize, or otherwise change the physical form of solid, semi-solid, and liquid food matter. Food manufacturers alter the form and size of the food matter to increase the efficiency and effectiveness of the food for further processing. 

The following processes are carried out by Mechanical Processing Equipment: 

  • Size Reduction
  • Size Enlargement 
  • Homogenization
  • Mixing 

3) Heat Processing Equipment 

Heat Processing Equipment can influence not only the physical changes in the food material, but also bring about chemical, and biochemical changes. These changes transform and affect the overall quality of the resulting food products by altering their chemical structure or by enhancing their flavor. 

The following processes are carried out by Heat Processing Equipment: 

  • Baking 
  • Blanching 
  • Dehydration 
  • Evaporation
  • Frying 
  • Pasteurization 
  • Roasting 
  • Sterilization 

4) Preservation Equipment 

The preservation stage of the food processing production cycle ultimately aims to prevent or inhibit spoilage of the food product and increase its shelf life. Preservation methods range from refrigeration to irradiation, each of which acts to destroy microorganisms and enzymes within the food material or, at the very least, limit and depress their activity.

The following processes are carried out by Preservation Equipment: 

  • Chemical 
  • Irradiation 
  • Refrigeration
  • Water Reduction

5) Packaging Equipment 

Following the preparation and processing stages, food material generally undergoes one or more post-processing operations, which help to produce the final food product and complete the food processing production cycle. 

The following processes are carried out by Packaging Equipment: 

  • Containment 
  • Protection and Preservation 
  • Convenience 
  • Communication
