Quality of conilon coffee dried on a concrete terrace in a greenhouse with early hulling

Abstract: The time spent in coffee drying is quite important for keeping the product quality and therefore choosing the appropriate method to be used. This study was performed to quantify the decrease in drying time as a result of early hulling of conilon coffee (Coffea canephora) dried on a concrete terrace in a greenhouse, as well as to determine the quality of the dried coffee. The coffee was harvested at more than 80% ripe fruits and immediately placed on concrete terraces in greenhouses for drying. The parcels were… Show more

“…Values below 142 (mL NaOH 0,1 mol L -1 /100g) were obtained for higher quality coffees dried in a greenhouse, indicating that the higher the TTA value, the higher the acidity, the lower the coffee quality. Partelli et al (2014) found total titratable acidity equal to 213 (mL of NaOH 0.1 mol L -1 / 100g) for a sample of conilon coffee with 13% humidity and 75.50 points of sensory analysis. The pH values at 25 o C were very close for all samples analyzed (mean value of 5.99), and pH values at 96 o C did not show a significant difference (P < 0.05), with an average of 5.86.…”

“…Abreu et al (2017) used techniques to simulate the time and the appropriate temperature for the storage beans of Coffea arabica, mechanically peeled after drying with skin, and concluded that the storage time was 90 days and at a temperature of 10 ºC, indicating that this conditions is suitable for beans quality and sensory analysis. Partelli et al (2014) studied the quality of the beverage obtained from dry Coffea Canephora on the concrete floor in greenhouse. The samples were peeled when 22%, 19% and 16% (wb) moisture.…”

“…10 Definir a qualidade do café não é, de modo algum, um esforço simples. 65 Neste sentido, a fim de atender a demanda pelo aumento do consumo café, sobretudo, por cafés especiais, 66 estudos buscam relacionar diferentes métodos de secagem 67,68 e aplicação da enzima polifenoloxidase (PPO) 69 para efeitos na melhoria dos atributos sensoriais de café conilon que, por sua vez, possui um menor valor comercial em relação ao café arábica devido ao seu reduzido perfil sensorial em função dos altos níveis de cafeína e ácidos clorogênicos, responsáveis pela amargura e adstringência. 55,70 Para o café arábica, pesquisas tem sido realizadas a fim de avaliar o potencial do tratamento químico sobre o café tipo rio, que apresenta sabor mais acentuado de iodofórmio, em relação a percepção de melhoria de qualidade sensorial.…”
