This study aimed to simultaneously combine the characteristic volatile fingerprints with the odor activity values (OAVs) of different citrus teas for the first time by headspace gas chromatography-ion mobility spectrometry (HS-GC-IMS) and headspace solid-phase microextraction-gas chromatography-mass spectrometry (HS-SPME-GC-MS). Results showed that the establishment of a citrus tea flavor fingerprint based on HS-GC-IMS data can provide an effective means for the rapid identification and traceability of different citrus varieties. Moreover, 68 volatile compounds (OAV > 1) were identified by HS-SPME-GC-MS, which reflected the contribution of aroma compounds to the characteristic flavor of samples. -
Tropical Horticulture: Lecture 32 1
Tropical Horticulture: Lecture 32 Lecture 32 Citrus Citrus: Citrus spp., Rutaceae Citrus are subtropical, evergreen plants originating in southeast Asia and the Malay archipelago but the precise origins are obscure. There are about 1600 species in the subfamily Aurantioideae. The tribe Citreae has 13 genera, most of which are graft and cross compatible with the genus Citrus. There are some tropical species (pomelo). All Citrus combined are the most important fruit crop next to grape. 1 Tropical Horticulture: Lecture 32 The common features are a superior ovary on a raised disc, transparent (pellucid) dots on leaves, and the presence of aromatic oils in leaves and fruits. Citrus has increased in importance in the United States with the development of frozen concentrate which is much superior to canned citrus juice. Per-capita consumption in the US is extremely high. Citrus mitis (calamondin), a miniature orange, is widely grown as an ornamental house pot plant. History Citrus is first mentioned in Chinese literature in 2200 BCE. First citrus in Europe seems to have been the citron, a fruit which has religious significance in Jewish festivals. Mentioned in 310 BCE by Theophrastus. Lemons and limes and sour orange may have been mutations of the citron. The Romans grew sour orange and lemons in 50–100 CE; the first mention of sweet orange in Europe was made in 1400. Columbus brought citrus on his second voyage in 1493 and the first plantation started in Haiti. In 1565 the first citrus was brought to the US in Saint Augustine. 2 Tropical Horticulture: Lecture 32 Taxonomy Citrus classification based on morphology of mature fruit (e.g. -
