7种不同果型草果果粉的理化指标及挥发性成分分析
Analysis of Physicochemical Indexes and Volatile Components of Seven Amomum tsaoko Powder
摘要
Abstract
The study was aimed to explore the differences in physical and chemical indexes and volatile components of different types of Amomum tsaoko powder.The physicochemical indexes of A.tsaoko powder such as color difference,essential oil content,moisture content,particle size and surface microstructure were investigated.The volatile compo-nents of A.tsaoko powder were analyzed by headspace solid-phase microextraction and gas chromatography-mass spec-trometry.The color difference ∆E of seven different fruit types of A.tsaoko powder was from 19.17±0.29 to 25.15±0.17,L* value was from 72.50±0.23 to 76.87±0.07,a* value was from 5.17±0.05 to 6.97±0.15,b*value was from 12.35±0.43 to 16.91±0.43.The content of volatile oil was from(0.76±0.01)mL/100 g to(1.30±0.26)mL/100 g.The moisture content was from 11.13%±0.12%to 15.05%±0.23%.In terms of particle size,NL5 and NL6 fruit powder particles had the larg-est difference.A total of 31 volatile components were detected in the seven fruit powder,and 17 common components were detected,mainly aldehydes and alcohols,including 2-decenal,(E)-,eucalyptol,citral,geraniol,geranyl acetate,etc.Among them,28 volatile components were detected in NL2 fruit types,and the relative content of 2-decenal,(E)-was the highest(22.24%±2.29%).The relative content of eucalyptol in NL5 fruit type was the highest(17.52%±2.16%).Therefore,there are some differences in color difference,essential oil content,moisture content,particle size and sur-face microstructure of the powder of different fruit types.The volatile components of different fruit types of A.tsaoko fruit powder have both common characteristics and differences.The research could provide theoretical guidance for the production and application of high-quality pure natural A.tsaoko powder.关键词
