Abstract

One of the most notable advances in the food industry was the introduction of chemical additives, such as dyes, since their use in most foods is just by eating habits. There are a variety of substances with coloring power, however, vary substantially dyes allowed in each country, due to its current legislation, applications and their harmful effects on human health. The use of natural colorants is dependent on issues related to throughput and process costs, since it depends on raw materials derived from natural sources. Most synthetic dyes shows toxic activities, mutagenic and resistant to degradation. Since 1972, at the Stockholm Conference, the environmental law began to acquire legal character, concerns about the environment and the harmful effects that chemical processes bring to ecosystems increase and continue to be concern of many international debates and academic technology research. Thus, green chemistry has been developed in support of the environmental and human needs in an attempt to reduce or eliminate the possible hazards and damage to health by developing methodologies in their processes and replacing reagents and raw materials. In this scenario, the natural dyes gain opportunity and expansion of use, with room for further research in order to replace the synthetic dyes, as far as possible, and reduce the negative impact of such additives in everyday life. In this research project, it is proposed to obtain natural dyes, apply them in biodegradable packaging produced by the company OKA Bioembalagens Botucatu / SP and study the stability of natural dyes compared with synthetic dyes.
