Abstract

Dried guajillo peppers were first extracted with four different solvents: ethanol, acetone, ethyl acetate and hexane with the aim of obtaining oleoresins which were further fractionated into red and paprika extracts. Results showed that as the polarity of the solvent increased the amount of pigments extracted also increased. Acetone had good affinity for pungent (capsaicin) compounds. Utilization of these solvents alone did not produce red and paprika oleoresins that meet commercial specifications. Fractionation of acetone extracted oleoresins with ethanol: water (90:10) yielded a precipitate and a solution. The precipitate and solution produced red and paprika extracts that meet pungency and color specifications. It was possible to obtain red and paprika oleoresins from mild guajillo peppers.

摘要

首先用四种不同的溶剂（乙醇、丙酮、乙酸乙酯和己烷）对干瓜希略辣椒进行萃取，目的是获得油树脂，然后将其进一步分离成红色提取物和辣椒粉提取物。结果表明，随着溶剂极性的增加，提取的色素量也增加。丙酮对辛辣（辣椒素）化合物具有良好的亲和力。单独使用这些溶剂并不能生产出符合商业规格的红色和辣椒粉油树脂。用乙醇：水（90:10）对丙酮萃取的油树脂进行分馏，得到一种沉淀物和一种溶液。该沉淀物和溶液产生了符合辛辣度和颜色规格的红色和辣椒粉提取物。从温和的瓜希略辣椒中获得红色和辣椒粉油树脂是可能的。
