FENNEMA’S FOOD CHEMISTRY FIFTH EDITION

FENNEMA’S FOOD CHEMISTRY FIFTH EDITION

Description :

Unnoticed in the darkness of a subterranean cavern, a water droplet trickles slowly down a stalactite, following a path left by countless predecessors, imparting, as did they, a small but almost magical touch of mineral beauty. Pausing at the tip, the droplet grows slowly to full size, then plunges quickly to the cavern oor, as if anxious to perform other tasks or to assume different forms. For water, the possibilities are countless. Some droplets assume roles of quiet beauty - on a child’s coat sleeve, where a snowake of unique design and exquisite perfection lies unnoticed; on a spider’s web, where dew drops burst into sudden brilliance at the rst touch of the morning sun; in the countryside, where a summer shower brings refreshment; or in the city, where fog gently permeates the night air, subduing harsh sounds with a glaze of tranquility. Others lend themselves to the noise and vigor of a waterfall, to the overwhelming immensity of a glacier, to the ominous nature of an impending storm, or to the persuasiveness of a tear on a woman’s cheek. For others the role is less obvious but far more critical. There is life - initiated and sustained by water in a myriad of subtle and poorly understood ways - or death inevitable, catalyzed under special circumstances by a few hostile crystals of ice; or decay at the forest’s oor, where water works relentlessly to disassemble the past so life can begin anew. But the form of water most familiar to humans is none of these; rather, it is simple, ordinary, and uninspiring, unworthy of special notice as it ows forth in cool abundance from a household tap. “Humdrum,” galunks a frog in concurrence, or so it seems as he views with stony indifference the watery milieu on which his very life depends. Surely, then, water’s most remarkable feature is deception, for it is in reality a substance of innite complexity, of great and unassessable importance, and one that is endowed with a strangeness and beauty sufcient to excite and challenge anyone making its acquaintance.

AVANT PROPOS

Welcome to the fth edition of Fennema’s Food Chemistry. The 11-year interval from the fourth edition has prompted transitions in contributors and content evoked by the waxing and waning of careers, and discoveries based on another decade of research and development. New contributors and co-contributors appear for chapters on “Water and Ice”, “Colorants”, “Bioactive Substances: Nutraceuticals and Toxicants”, “Characteristics of Milk” and “Postharvest Physiology of Edible Plant Tissues”. The Chapters titled ‘’Physical and Chemical Interactions of Components in Food Systems” and “Impact of Biotechnology on Food Supply and Quality” have been omitted from the 5th Edition. In contrast, some things never changed. Dr. Robert Lindsay has been the sole author of the “Food Additives” chapter in all ve editions (titled “Other desirable constituents of food” in the rst edition) and “Food Flavors” in the second through the fth edition, despite our efforts to nd a better contributor. Some acts are just tough to follow. We are greatly appreciative of the authors’ efforts in preparing the fth edition, for the seriousness and dedication they invested in preparing chapter revisions and complete rewrites to bring the content of Fennema’s Food Chemistry up to date as much as possible. On a very sad and somber note, many of you are aware that Dr. Owen Fennema made his nal transition in life in August 2012. Sir Isaac Newton said, “If I have seen further it is by standing upon the shoulders [sic] of giants.” For those of us privileged to have had our lives touched by Owen, we have beneted from the perch of insight he offered, enabling us to see further than we could have on our own. He also inspired us by the manner in which he conducted himself as a scientist, professional, and human being. This fth edition is dedicated to Dr. Owen Fennema, and, in that context, we share with you the following two documents.
