The specialized book "Post-Harvest Losses and Value Addition of Grapes in India" offers a comprehensive analysis of the challenges associated with the post-harvest processing of grapes in India. Grapes are a significant fruit variety that constitutes a substantial part of Indian fruit production. The book highlights the various factors that contribute to post-harvest losses, including harvesting, packaging, and transportation methods. These losses not only affect the availability of grapes for the population but also impact the economic stability of the country. A central concern of the book is the development of a methodology for the quantitative assessment of these losses in both physical and monetary terms. Additionally, it emphasizes the need to revise the estimation of marketing margins and costs to better account for the impacts of post-harvest losses.
