HCCI – HunterLab Coffee Color Index measures the reflectance of ground coffee products at 640 nm, which is optimal for defining the degree of roast.

HCCI works best for measuring during the roasting process, taking the coffee product to a consistent end point.

HCCI = [HCCI_slope * R%(640 nm)] + HCCI_offset

where default coefficients for HCCI_slope = 1.958 and HCCI_offset = – 3.32.

HCCI* comes with a user-adjustable bias and offset in each setup to allow display in agreement with existing instruments.

HCCI values are typically displayed to 1 decimal place.

HCCI correlates well with the visual SCAA Roast Standards and exhibit 20 unit range.

The HunterLab ColorFlex EZ Coffee meter comes with a built-in correlation to report HCCI – HunterLab Coffee Color Index, SCAA # and SCAA Roast Classification, all used to quantify the degree of coffee roast.

HCCI - HunterLab Coffee Color Index は、挽いたコーヒー製品の反射率を640nmで測定します。

HCCIは、焙煎工程中の測定に最適で、コーヒー製品を一貫した終点まで導く。

HCCI = [HCCI_slope * R%(640 nm)] + HCCI_offset

ここでHCCI_slope = 1.958、HCCI_offset = - 3.32がデフォルトの係数である。

HCCI*は、既存の測定器と一致した表示ができるように、各セットアップにユーザー調整可能なバイアスとオフセットが付属しています。

HCCIの値は通常、小数点第1位まで表示される。

HCCIは視覚的なSCAAロースト規格とよく相関し、20単位の範囲を示す。

HunterLab ColorFlex EZコーヒーメーターには、HCCI（HunterLabコーヒーカラーインデックス）、SCAA#、SCAAロースト分類をレポートする相関関係が内蔵されており、これらはすべてコーヒーの焙煎度を数値化するために使用されます。
