高油酸葵花籽油作为糖衣中棕榈油的潜在替代品—使用多光谱成像和电子鼻的比较质量测定 

摘要：棕榈油因对农民的剥削和对濒危动物栖息地的破坏而声名狼藉。因此，许多消费者希望避免使用棕榈油。装饰糖含有少量棕榈油，以防止糖在热烘焙产品上融化。本研究通过多光谱成像和电子鼻分析了用作棕榈油替代品的高油酸葵花籽油，这两种方法适用于糖/油涂料的潜在大批量分析。多光谱成像是一种用于比较样品表面波长反射的无损方法。参考样品能够估计未知样品的质量，这些样品通过酸值测量得到确认。此外，为了测定质量，用电子鼻测量装饰糖中的挥发性化合物。这两种应用都提供了可比较的数据，提供了有关装饰糖质量的信息。

High-Oleic Sunflower Oil as a Potential Substitute for Palm Oil in Sugar Coatings—A Comparative Quality Determination Using Multispectral Imaging and an Electronic Nose 

Abstract: Palm oil has a bad reputation due to the exploitation of farmers and the destruction of  endangered animal habitats. Therefore, many consumers wish to avoid the use of palm oil. Decorative sugar contains a small amount of palm oil to prevent the sugar from melting on hot bakery products. High-oleic sunflower oil used as a substitute for palm oil was analy zed in this study via multispectral imaging and an electronic nose, two methods suitable for potential large-batch analysis of sugar/oil coatings. Multispectral imaging is a nondestructive method for comparing the wavelength reflections of the surface of a sample. Reference samples enabled the estimation of the quality of unknown samples, which were confirmed via acid value measurements. Additionally, for quality determination, volatile compounds from decorative sugars were measured with an electronic nose. Both applications provide comparable data that provide information about the quality of decorative sugars.
