Rosemary is an important medicinal and aromatic plant and is cultivated for its valuable essential oil. It is well known that the activity of both the essential oil as well as rosemary extracts in the food industry is due to the presence of some important compounds such as carnosol and carnosic acid. Due to its antioxidant and antimicrobial activity, it can serve as a potent natural food additive in the food industry. Also because of its flavoring agent, it can be used as an alternative to synthetic food flavoring agents. Since the current demand in the food industry is the reduction or elimination of the use of synthetic food additives which can be met by the application of rosemary oil and extracts. In this review, a brief introduction to rosemary plant, its health benefits, and applications as a food additive in food industry are discussed.

Sixty surface (0-20 cm) soil samples each from the farmers paddy field collected from different villages in Gangavati taluk, North Karnataka in the year 2010. Distributions of different forms of zinc in twelve village paddy growing soils were studied. The results showed that more than 79.38% in Herura village and 99.35% in Maralanahalli village of total zinc occurred as residual zinc, whereas water soluble + exchangeable Zn occurred only in 0.11% in Maralanahalli village and 6.71% in Sanapura village soil samples. Soils contained water soluble + exchangeable zinc from 0.13 to 1.93 ppm, organically bound zinc from 0.16 to 5.32 ppm, manganese oxide bound zinc from 1.00 to 5.89 ppm, amorphous sesquioxides bound zinc from 0.09 to 2.16 ppm, crystalline sesquioxides bound zinc 1.21 to 9.94 ppm and residual zinc from 53.29 to 277.99 ppm. In this fractions water soluble + exchangeable zinc was low in all the soils when compared to other fractions, still it is very important from the plant availability point of view. Amorphous sesquioxidebound form of zinc is the seat for zinc adsorption because of its high specific surface area. Crystalline sesquioxide bound form of zinc dominated when compared to water soluble + exchangeable, organically bound, manganese oxide bound and amorphous sesquioxide bound zinc fractions.
