Abstract

ABSTRACT The nutritional and sensory qualities of tomatoes favor their acceptance worldwide. This study was carried out to evaluate the risk perception of agrochemical and sensory residue in tomato consumption. Thus, 12 kg of organic tomatoes (OT) and 12 kg of conventional tomatoes (CT) at an equal maturation stage were selected. R version 3.6.1 was applied to the analysis of physical and chemical variables. The Mann-Whitney test with a value of p<0.05 was used to verify associations between the groups. The sensory evaluation involved 37 volunteers and considered the mean answers of each question about the perception of fresh tomatoes. The OT presented about 13% more ascorbic acid in relation to CT, but there was no significant difference between them (p>0.05). OT detected higher values for pH, soluble solids (ºBrix) and titratable acidity, but there were no significant differences between them (p>0.05). Chlorfenapir residues below the Acceptable Daily Intake (IDA) value (0.03 mg/kg per capita) were detected, indicating a low risk of acute toxicity. Chlorfenapir is banned in Europe, but remains detected in Brazil. Public policies are needed to encourage sustainable food production.

巴西圣保罗露天市场新鲜番茄的风险认知和感官分析
西红柿的营养和感官品质使其在世界范围内被接受。本研究对番茄消费过程中农药残留和感官残留的风险认知进行了评价。因此,在相同的成熟阶段,选择了12公斤的有机番茄(OT)和12公斤的传统番茄(CT)。使用R 3.6.1版本进行理化变量分析。Mann-Whitney检验,p0.05)。OT检测到pH、可溶性固形物(Brix)和可滴定酸度较高,但两者之间无显著差异(p < 0.05)。检测到低于可接受日摄入量(IDA)值(人均0.03 mg/kg)的氯非那韦残留,表明急性毒性风险较低。氯非那匹在欧洲被禁用,但在巴西仍能检测到。需要制定公共政策来鼓励可持续粮食生产。
