Preserve


It is customary to add preservatives for enhancing shelf life of processed foods. Common salts, sugar and oil are three preservatives widely used by housewives. In food processing industry, many chemical preservatives are used to prevent growth of fungus. In the present experiment this aspect is studied in a systematic way. Preservative is used in different quantities. pH and water activity level are two other factors that affect chance of fungal growth. It is of interest to delineate a 'safe zone', set of conditions under which probability of fungal growth is very small. 


datasets

Collection of datasets as prepared by Profs. A.P. Gore, S.A. Paranjape, and M.B. Kulkarni of Department of Statistics, Poona University, India. With their permission, first letter of their names forms the name of this package, the package has been built by me and made available for the benefit of R users. This collection requires a rich class of models and can be a very useful building block for a beginner.
