本研究的目的是评估SIMCA方法和近红外光谱的非侵入性和非破坏性分类的印尼特色咖啡,来自两个地理来源:加约咖啡亚齐10个样品和瓦梅纳从巴布亚10个样品。所有样品在相同条件下烘烤(在200 ℃的温度下中等烘烤10分钟),并使用家用咖啡研磨机研磨,然后使用50目筛筛分以获得297微米的均匀粒度。在漫反射模式下,使用两个配备有积分球的手持式光谱仪(ISP-REF,Ocean Optics,USA)测量650-1650 nm的短和长近红外范围内的光谱数据。结果表明,该分类的准确性、敏感性和特异性均为100%。
The objective of this study is to evaluate the SIMCA method and NIR spectroscopy for the non-invasive and non-destructive classification of Indonesian specialty coffees that come from two geographical origins: Gayo coffee from Aceh 10 samples and Wamena from Papua 10 samples. All samples were roasted at the same condition (medium roasting at a temperature of 200 C for 10 minutes) and were ground using a home coffee grinder and then sieved using 50 mesh to obtain a homogenous particle size of 297 micrometers. Spectral data in the short and long near infrared range of 650–1650 nm was measured in a diffuse reflectance mode using two handheld spectrometers equipped with an integrating sphere (ISP-REF, Ocean Optics, USA). The result demonstrated that the classification was satisfied with 100% accuracy, sensitivity, and specificity.
