Extração de pectina de goiaba desidratada

Abstract: Goiabas (Psidium guajava L.) cultivar Pedro Sato foram utilizadas para extração de pectina. Os frutos separados polpa e polpa com casca foram secos em estufa com circulação de ar. Amostras secas foram caracterizadas física e quimicamente. O planejamento composto central rotacional com quatro pontos axiais e três repetições no ponto central foi utilizado para determinar o rendimento de extração de pectina das farinhas de polpa e de polpa com casca de goiaba. A extração foi realizada em 4 g de farinha para 200 m… Show more

“…The treatment stage is responsible for the structural fragmentation of the material, and the formation of pores can occur. Acid treatment promotes greater removal of polysaccharides such as pectin, which may be an indication of greater fragmentation [31][32][33]. Figure 4 shows the DRX of the adsorbents with cellulose as a standard.…”
