Vegetables and Vegetable Products

The analysis of vegetables and vegetable products is now an important part of everyday life. From the dietary point of view we need to know both the positive and negative aspects of the vegetables we consume - whether they have a high fibre content, for example, or what pesticide residues are present. And from the producers' standpoint, we need to know the methods that are being used to develop new and better vegetables. Thus, genetic analysis becomes important. In this book, a chapter on genetic mapping of pea is included, together with approaches to squash and pumpkin breeding with high carotene content. Also, there are chapters covering the analysis of leaf protein and the oxalic acid content of vegetables, and the analysis of vegetables consumed in tropical Africa. All in all, it is a useful book to have on the shelf for those interested in horticulture, human nutrition or chemical analysis.
