Persimmon () is an underutilized tree fruit. Previous studies have shown the feasibility of making a hot-air-dried, chip-style product from persimmon. However, the texture of this type of product has not been explored or connected to consumer preference. Thus, for dried samples representing 37 cultivars, this study aimed to (1) predict trained sensory panel texture attributes from instrumental measurements, (2) predict consumer liking from instrumental measurements and sensory texture attributes, and (3) elucidate whether astringency type affects dried product texture. Partial least-squares regression models of fair-to-good quality predicted all measured sensory texture attributes (except Tooth Packing) from instrumental measurements. Modeling also identified that consumer preference is for a moist, smooth texture. Lastly, while astringency type has significant ( < 0.05) effects on several individual texture attributes, astringency type should not be used a priori to screen-in or -out persimmon cultivars for processing into a hot-air-dried product.
柿子是一种未得到充分利用的树生果实。先前的研究已表明用柿子制作热风干燥的片状产品具有可行性。然而,此类产品的质地尚未得到探究,也未与消费者偏好建立联系。因此,针对代表37个品种的干燥样品,本研究旨在:(1)根据仪器测量结果预测经过培训的感官评定小组的质地属性;(2)根据仪器测量结果和感官质地属性预测消费者的喜好程度;(3)阐明涩味类型是否会影响干燥产品的质地。质量为中等至良好的偏最小二乘回归模型根据仪器测量结果预测了所有测得的感官质地属性(除了牙齿咬合感)。建模还确定消费者偏好湿润、光滑的质地。最后,虽然涩味类型对几个单独的质地属性有显著影响(P<0.05),但涩味类型不应预先用于筛选用于加工成热风干燥产品的柿子品种。
