Item Acesso aberto (Open Access) Physicochemical properties of three sugary cassava landraces(2013-05) SOUZA, Hugo Antonio Lima de; BENTES, Ádria de Sousa; LADEIRA, Taiana Marina Souza; LOPES, Alessandra Santos; PENA, Rosinelson da SilvaThis study evaluates the physical and physicochemical properties of three sugary cassava (Manihot esculenta Crantz) landraces: São Francisco Bag 3, Manicueira 62, and Castanhal Iracema. These three landraces showed high estimated productivity (≥3.93kg plant-1) and had a high sugar content (≥3.92g 100g-1 of root), making them viable for use in syrup production, especially the São Francisco Bag 3 landrace (4.76g 100g-1). The Manicueira 62 landrace had the highest starch content (4.40g 100g-1). The three sugary cassava landraces exhibited high levels of cyanide (>195mg kg-1), indicating the need for processing prior to consumption.Item Acesso aberto (Open Access) Qualidade da farinha de mandioca do grupo seca(Universidade Federal do Pará, 2006-12) CHISTÉ, Renan Campos; COHEN, Kelly de Oliveira; MATHIAS, Erla de Assunção; RAMOA JÚNIOR, Afonso Guilherme AraújoIn the north of Brazil, cassava flour is produced in small-scale processing units called ´flour mill houses'. These processing units have difficulty in complying with current legislation due to processing methods and to poor sanitary conditions. The objective of this study is to evaluate the quality standard of cassava flour from the dry group, subgroup "fina", type 1. Ten samples of cassava flour were collected from the main supermarkets and free markets in Belém-PA, and the physical-chemical, microbiological and dirt research analyses were carried out. According to Regulation nº 554 from 08/30/1995 issued by the State Agriculture Secretariat, all cassava flour samples analyzed showed total acidity values above the permitted standard (3 meq NaOH/100 g) and five samples were below the minimum tolerance level required for starch (75%). According to Resolution RDC nº 12 from 01/02/2001 of the National Sanitary Control Agency, all cassava flour samples were under the acceptable standards for microbiological contaminants. According to Resolution CNNPA nº 12 from 1978, eight of the analyzed samples did not comply to the permitted standards because they showed dirt.
