Post Harvest Operations and Processing of Fruits, Vegetables, Spices and Plantation Crop Products


Prof. Hari Niwas Mishra


*Additional GST and optional Exam fee are applicable.



Horticultural and plantation crops have always played an important role in Indian dietary. Globally, India is the second-largest producer of fruits and vegetables. However, only about 2-3% of the produce is processed and converted into value-added products. About 15 to 20 % of the produce, in some cases even more, is wasted due to improper cold storage infrastructures, transportation systems, lack of technical knowledge, skilled labour, and limited processing. It is necessary to develop skills and increase the technical knowledge base in the sector of novel post-harvest handling, processing, packaging, and storage technologies and infrastructure to improve availability and accessibility of the produces, improve the nutritional status of country, provide nutritional security, increase the agri-startups and improve nation’s economy.

This online course is being offered to disseminate the knowledge on recent developments and innovations in different science and engineering domains of post-harvest management and processing of fruits, vegetables, spices, and plantation crop products. This course will develop trained human resource for the food industry and prepare them to face the newer challenges in the fast-expanding sector of horticultural & plantation crop products processing. Also, this course will provide ample materials to the students for the preparation of competitive examinations like GATE, NET, etc.

INTENDED AUDIENCE: Food Processing and Engineering, Food Technology, Agricultural Engineering, Biochemical Engineering, Post  Harvest Technology, Chemical Engineering, Horticulture and related disciplines.
INDUSTRY SUPPORT: Food industries such as Britannia Industries Ltd, Nestle,  Hindustan Unilever Ltd, Patanjali, PepsiCo Frito Lay,  General Mills, Glaxo, ITC, Parle, Coca Cola, Keventer  Agro, Reliance Fresh, etc.
