Metodologias para determinação de massa específica de grãos

Abstract: Resumo: A massa específica é um dos principais índices qualitativos dos grãos e essa propriedade é influenciada por fatores como teor de impurezas, variedade e teor de água. Assim, objetivou-se com este trabalho verificar se a metodologia empregada para determinar a massa específica pode ser apontada como uma fonte de variação dos resultados dessa propriedade. Foram utilizados grãos de: arroz (em casca e beneficiado), feijão, girassol, milho e soja. As metodologias utilizadas para a determinação da massa espec… Show more

“…The ASG was determined using a mass scale of the hectoliter weight of the Dalle Molle ® brand (model TYPE 40), which is based on the determination of the mass of grains contained in a container of volume of ¼ L (Botelho et al, 2018). The results are expressed in kg/hL for HW and converted to kg•m -3 to express ASG.…”

“…Knowledge of this physical property is important for sizing silos, dryers, warehouses, and transport systems, and can be used to determine moisture levels and damage caused by insects and pests, causing loss of dry matter in stored grains (Ascheri & Germani, 2004). ASG is considered a physical property indicative of quality, it is used to define prices in the marketing of grains and seeds (Botelho et al, 2018). Considering that the LP moisture was within the recommended content (13.01%) and free of impurities when the ASG was measured, the relatively high value observed in our study may be due to the content of vitreous endosperm, which has a matrix dense protein with structured protein bodies that surround the starch granules, forming a compact structure (Coelho et al, 2018;Delcour & Hoseney, 2010).…”

“…According to Manley et al (2009), two types of devices are being used at present: i) those equipped with a funnel which provides uniform packing in a 500-ml (South Africa and Canada) or 1100-ml (USA) measuring cups and ii) chondrometer of 500 ml (Australia and the United Kingdom) or 1000 ml volume (France and Germany). For experimental purposes, a 250-ml chondrometer has been an option to measure test weight (Stagnari et al, 2008;Durazzo et al, 2015;Botelho et al, 2018).…”

“…The second is a 500 ml chondrometer used in the United Kingdom and Australia or of 1000 ml chondrometer used in Germany and France. For experimental purposes, a small chondrometer (250 ml) has been used in wheat (Stagnari et al, 2008;Durazzo et al, 2015;Botelho et al, 2018), in triticale (Messia et al, 2012;Redaelli et al, 2015;Kuzmanovic et al, 2020) and in oats (Nava et al, 2010;Buerstmayr et al, 2007;Martinez et al, 2010;Da Silva et al, 2015).…”
