Recent Research Advancements of Coffee Quality Detection: Targeted Analyses vs. Nontargeted Fingerprinting and Related Issues

Table 1

Advantages and limitations of different detection methods in coffee quality.

Detection methods	Advantages	Limitations	References
Microscope	Simpleness, convenience, and without pretreatment	Low accuracy, destructiveness, limited detection, and subjectivity (samples and adulterants need to be compared visually)	[25]
Chromatography	Quantitative detection and accuracy	Costly operation, time-consuming, and requires specific markers	[32, 50–52]
Spectroscopy	Fast and nondestructive analysis	Poor accuracy and complex metrological analysis	[53, 54]
Mass spectrometry	Precision and sensitivity	High cost and require pretreatment	[55]
Array sensors	Convenience and simpleness	Poor accuracy and sensitivity and limited measurement range	[56]
Sequencing methods	Accuracy and sensitivity	Need to consider the DNA pattern and endogenous genes of a specific substance and complicated operation	[57]
Thermal, digital image and other new detection techniques	Modernization, sensitivity, and other unique merits	Newly developed, not widely available, and needs further study	[58, 59]
