The site of the Ethiopian Business Development Services Network will be of great value to Ethiopian businesses, but also contains some information that would be of interest to any entrepreneur considering a food processing business.
In particular it has a detailed section on costing with a focus on fixed and variable costs, price setting and cost reduction.
This is a comprehensive publication covering the supporting business and organisational issues as well as focussing on idea generation and screening, product concepts and design specifications & product design and process development.
The body of the book is presented in a straight forward and clear manner and is supported by examples and ideas for further thought.
In a previous post I gave information about an online book on Unit Operations in Food Processing that had been published by the New Zealand Institute of Food Science . To me this was a very informative and useful book on the engineering aspects of food processing.
