p1, an analyzer to distinguish 10 brands coffee, dif temperature, time; help growers determine
p2, trying for years, no easy becs the aroma--1000 compounds change with temp and time when roasted
gas+ mass s: difficulty distinguishing similar compounds
"electronic noses", other sensors: change colour or chemical properties when react
p3, KS, refined electronic noses: dyes making them specific--36 drops--a range of chemical classes(m, pH, molecules)
p4, produce unique color patterns
p5, the array doesn't give infor about individual compounds in the aromas, but tell differences
words:
tell apart 分辨,区分;volatile 挥发的,反复无常的
