Food Preservatives Essay
Due to the need of keeping the food's natural characteristics and taste for longer as well as to meet the requirements of food manufactures many chemical compound have been discovered and developed as ways to preserve food and extend their life for longer. With the increasing of new technologies, transportation and a growing population, food processing which requires the use of preservatives, ensures the extension of shelf life of many foods and beverages. There are many different types of food preservatives that are added to our daily diet. Butylated hydroxyanisole and Butylated hydroxytoluene are among the chemical compounds used in certain food and beverages to ensure their preservation. The objective of this paper is to discuss the use

Since the lifespan of rats is short, scientists believe that problems will be noticeable sooner than over the lifespan of humans who ingest normal amounts. When rats are fed massive quantities of BHA and BHT, some health problems have developed. Since this is the case, some scientists believe that these results are probably negligible when determining their importance for human safety since there are many things we can consume safely in small quantities but would die from in massive amounts. However they are taking into account something called bioaccumulation. Bioaccumulation refers to the accumulation of substances, such as pesticides, or other chemicals in an organism (8). Bioaccumulation occurs when an organism absorbs a toxic substance at a rate greater than that at which the substance is lost (8). Since BHA and BHT are extensively used not only in the food industry but also the cosmetic and pharmaceutical industry we are becoming more exposing to the them which can lead to bioacumulation. The Estimated annual U.S. use of BHA in food increased from 170,000 kg (374,000 lb) in 1960 to 300,000 kg (660,000 lb) between 1970 and 1982 (3). Unfortunately I could not find recent estimative but we can predict by the trend that these number probably doubled after
