A platform was being constructed from one storage tank to another, without the workers knowing that mixture of benzoic acid and air in the open storage tank could explode. DSM is the largest European producer of benzoic acid which is used in a range of applications from a pla.sttcizcf to food preservative. DSM s capacity here is 440 million lb per year. 

Another potential application of radioactive species is in food preservation (Figure 19.2, p. 518). It is well known that gamma rays can kill insects, larvae, and parasites such as...

The obliteration of these iron-dependent oxidative processes by phytate suggests that this ubiquitous and abundant plant component functions as a natural antioxidant, preventing oxidative damage during storage of seeds. Surface treatment with phytic acid of various fruits and vegetables preserved their color, texture and flavor (7). Thus, dietary phytate may be a superior substitute for presently employed food preservatives, many of which pose significant health hazards. Additional applications of phytic acid are summarized in a recent review (34). 

Potential therapeutic applications of host defense peptides also include the lantibiotic nisin. Indeed, nisin has had an impressive history as a food preservative with FDA approval in 1988 for use in pasteurized, processed cheese spreads. The attractiveness of nisin as a potential therapeutic is also enhanced due to its relative resistance to proteases and broad spectrum Gram-positive antimicrobial activity including multidrug-resistant strains. Biosynexus Inc. has licensed the use of nisin for human clinical applications and Immucell Corp. has licensed the use of Mast Out, an antimastitic nisin-containing product, to Pfizer Animal Health." Indeed, nisin formulations have been used as an active agent in the topical therapies Mast Out and Wipe-Out for bovine mastitis, an inflammatory disorder of the udder that is the most persistent disease in dairy cows." ...

Benzoic acid and its derivatives are among the most widely used antimicrobial agents these, together with the propionates, sulfur dioxide, nitrates, nitrites and sorbic add, account for the bulk of food preservatives. A number of other compounds find use, however, in various miscellaneous applications, including 3-acetyl-6-methyl-3f/-pyran-2,4-dione (67)... 

In short, the trade in spices, usually carried out along the many historic spice routes, has been one of the most important commercial activities throughout ancient and modern times. The importance placed on spices is reflected by economic developments that began early in many ancient civilizations, where spices found applications in food preservation, cooking and traditional medicine.

Irradiation techniques are more and more widely utilized for industrial applications for instance, for food preservation, medical sterilization, and polymer processing. Such techniques require specific rules of control by means of accurate dosimetry [89]. In this context, new promising dosimeters based on resistance measurements of organic conducting crystals have been reviewed by Zuppiroli et al. [89]. The crystals utilized as dosimeters are either small needles (0.01 x 0.01 x 3 mm3) or larger plates (0.1 x 0.5 x 3 mm3), and their electrical resistances ( 1 kfl in the first case, 1 H in the second) increase exponentially with the adsorbed radiation dose, up to quite high doses.

Although a relatively new commercial process, food irradiation has been studied more thoroughly than any other food technology. More than 40 years of research have shown conclusively that there are no adverse effects from the consumption of irradiated food. In fact for many foods, preservation by irradiation has proved to be by far the best method. Table 4.4 summarises the general applications of food irradiation technology.
