What is Food Technology?

Food Technology is the science that deals with the processing, preservation, packaging, distribution, and quality management of food products. It combines principles of chemistry, biology, engineering, and nutrition to create safe and innovative food solutions.

Key Areas of Food Technology:

• Food Processing and Preservation

• Food Chemistry and Microbiology

• Dairy and Meat Technology

• Bakery and Confectionery Science

• Food Packaging and Quality Control

• Nutraceuticals and Functional Foods

What is Post-Harvest Technology?

Post-Harvest Technology (PHT) refers to the science of handling, storing, and preserving agricultural produce after harvesting to maintain quality and reduce losses. Since nearly 30–40% of agricultural produce is wasted due to poor post-harvest practices, this field is crucial for food security and farmer income.

Major Aspects of Post-Harvest Technology:

• Storage and Transportation

• Grain Drying and Milling

• Cold Chain Management

• Fruit and Vegetable Preservation

• Value Addition of Agricultural Produce

• Minimizing Post-Harvest Losses
