Obtenção e análise química do caldo e biomassa da casca do abacaxi (Ananas comosus L. Merril.) para desenvolvimento de formulação cosmética

Abstract

The Pineapple (Ananas comosus L. Merril.), belonging to the Bromeliaceae family, has a high concentration of Bromelain, a complex of proteolytic enzymes, in several of its tissues, including its peel. Bromelain has great potential for use as an active ingredient in cosmetic preparations, due to its power of cell renewal in the skin. The large production of the fruit in Paraíba, and in Brazil as a whole, associated to the non-use of its peel by its biggest consumer (the food industry), makes the pineapple peel an abundant, low cost and easy to acquire raw material. This work aimed to extract and characterize the chemical composition of pineapple peel extract and its biomass. As well as develop a formulation for a moisturizing body cream containing pineapple peel extract as an active ingredient and evaluate its stability. For the characterization of the plant materials obtained, physical chemical analyzes were carried out to determine the percentage of moisture, minerals, proteins, lipids, carbohydrates, sugars (total, reducing and non-reducing). To produce the body moisturizing cream, pineapple peel juice was used at a concentration of 3.0% in g per 100g of product. For the extract, a result of 86.923% moisture, 1.488% minerals, 0.442% proteins, 0.602% lipids, 10.545% carbohydrates, 10.4% total sugars, 4.7% reducing sugars was obtained and 5.7% of non-reducing sugars. For the biomass, a result of 1.179% moisture, 3.936% minerals, 4.778% proteins, 4.778% lipids, 88.054% carbohydrates, 31.4% total sugars, 22.2% reducing sugars was obtained and 9.2% of non-reducing sugars. The cream was produced by oil-in-water emulsion (O/W), where the oil phase is dispersed in the aqueous phase and obtained satisfactory stability results. Thus, the potential of plant materials obtained from pineapple peel as ingredients of a cosmetic formulation is evidenced.
