SUMMARY:

The processing of residues in the food industry is a current global trend of great importance because it allows the recovery and improves the economy of food processing. In Brazil, different forms of agro-industrial production work together with agricultural production. The characteristics and amount of agro-industrial residues produced are versatile over time. For the most part, processing is directly conditioned to the generation of products and, consequently, the generation of waste. Thus, the disposal of processing waste is a problem due to increased production. Thus, its efficient, safe and economical use is important for the environment and is becoming increasingly important due to profitability and possible jobs generated. The Food and Agriculture Organization of the United Nations (FAO) estimates that the world production of agro-industrial waste reaches 1.3 billion tons per year, with 1/3 of food destined for human consumption being wasted, either as waste. , arising from processing or as a loss in the production chain. Thus, the agro-industrial waste being used shows an initiative in the face of food waste, and the processing and processing of these, in addition to providing an opportunity for the development of by-products, with added value. According to the Food and Agriculture Organization of the United Nations (WHO/FAO, 1998), starch is the most important source of carbohydrates in human food, representing a percentage that varies from 80% to 90% of all polysaccharides in the diet. Starch is one of the natural polymers that has been gaining ground in studies of biodegradable materials for food packaging due to its low cost and film-forming property. Jackfruit seed is an unconventional source of starch, in addition to being a waste that is often not used. Jackfruit is a common fruit in Brazil and grows in warm regions. Its seeds are rich in starch and the use of this is configured in the recovery of the residue. This residue can be of paramount importance in the elaboration of biodegradable films, because when added to the compounds present in the acerola extract that will be added to its polymeric matrix, it can delay degradation, which is the need and desire of consumers and the industry. It was thinking like this that led to the development of antioxidant active packaging that has the ability to increase the shelf life of foods without needing to add antioxidants directly in the food formulation, with this, the need to incorporate the extract of acerola residue into the film to characterize it as active and antioxidant.
Based on all this context, the study aims to extract the starch from the jackfruit seed, extract the bioactive compounds from the acerola residue and use it in the elaboration of an active film.
