Quality and sensory acceptance of ‘Pérola’ pineapple grown in soil with application of organic fertilizer

ABSTRACT: Type of fertilizer and doses used are factors that influence the quality of pineapple fruit. This study aimed to evaluate the physico-chemical and sensorial quality of organically grown ‘Pérola’ pineapple and recommend the effective dose for best fruit quality, especially regarding sensorial acceptance. Effect of doses of 10, 20, 30, 40 and 50 t ha-1 of “bokashi” organic fertilizer on color, weight, pH, titratable acidity, soluble solids, soluble solids/titratable acidity ratio (SS/TA), vitamin C content, sensory acceptance and purchase intention was evaluated. Increasing doses of bokashi positively influenced weight and titratable acidity of the fruits and negatively affected the SS/TA ratio. Fruits produced with doses between 20t ha-1 and 40t ha-1. had good sensorial acceptance and were considered to have ideal acidity, sweetness and texture by most consumers. The authors recommend using 20 t ha-1 of bokashi, as this dose promotes the production of high quality fruits, with satisfactory SS/TA ratio and high sensorial acceptance.

摘要：肥料类型与施用剂量是影响菠萝果实品质的关键因素。本研究以有机种植的‘Pérola’菠萝为研究对象，旨在评估其理化与感官品质，并筛选可获得最佳果实品质（尤其是最优感官接受度）的有效施用剂量。本研究考察了施用剂量分别为10、20、30、40、50 t·ha⁻¹的bokashi有机肥对菠萝果实色泽、单果重、pH值、可滴定酸度、可溶性固形物含量、可溶性固形物/可滴定酸度比值（SS/TA）、维生素C含量、感官接受度及购买意愿的影响。结果显示，随着bokashi有机肥施用剂量的提升，菠萝果实的单果重与可滴定酸度呈正向提升趋势，而SS/TA比值则呈负向变化。施用20~40 t·ha⁻¹剂量bokashi有机肥所结的菠萝果实具备良好的感官接受度，且被多数消费者认定其酸度、甜度与质地均处于理想水平。本研究建议施用20 t·ha⁻¹的bokashi有机肥，该剂量可培育出高品质果实，其SS/TA比值符合生产要求且感官接受度优异。
