Fermented foods are very good for health and they have particular value, too, in being sources of nutrition that can be preserved for later consumption. This book makes a global contribution to the literature on fermented foods. Authors from many different countries present information from their local experience and research. The book's 23 chapters are contributed by 55 authors. While editors Sankaranarayanan and Amaresan (both, Uka Tarsadia Univ.) as well as Dhanasekaran (Bharathidasan Univ.) are all from India, contributing authors also hail from Brazil, Greece, Indonesia, Italy, Korea, Nigeria, Portugal, and Turkey. Many chapters include information on multiple fermented foods. Dairy products include amasi, borhani, cheese, dahi, kefir, rob, viili, and yogurt. Amasi is produced in Zimbabwe, while borhani is from Bangladesh. Rob is from Sudan and viili is found in Finland. Substrates for fermentation include cereals such as maize, millet, rice, sorghum, and wheat. Vegetables used include beets, cabbage, carrots, cauliflower, and cucumber, as well as eggplant, onion, and turnip. Fruits documented include durian, grapes, olives, and peaches. Tahiti and Taiwan are examples of island countries whose preserved foods are included. The book is written for readers who have an interest in fermentation processes and some background in foods. The useful index and many good references are an added attraction.--L. E. Erickson, emeritus, Kansas State University, Choice, 2020 Vol. 58 No. 4
