Description
「青果物流通技術の基礎知識」、(株)流通システム研究センター、2007年、p.45
式: 鮮度値= 脂質過酸化物当量 / (リン脂質当量 + 糖脂質当量 +脂質過酸化物当量)
を用いて算出することで、青果物の鮮度を高精度で確実に評価することが可能となる。
(第1実施例) 図1は、本発明の第1実施例の青果物の鮮度評価方法に適用される鮮度評価装置1の構成を模式的に示す図である。本実施例の鮮度評価装置1は、コンピュータ2と、計測手段3とを備えている。計測手段3は、リン脂質と、糖脂質と脂質過酸化物の含量を計測する。コンピュータ2は、計測手段3が計測した計測値から、青果物に含まれる脂質過酸化物当量と、リン脂質当量と、糖脂質当量を算出し、これらの値を用いて積算温度と高い相関を有する鮮度値を算出する算出手段と、算出された鮮度値に基づいて、前記青果物の鮮度を判定する判定手段としての機能を備えている。
(式1)
脂質過酸化物当量 / (リン脂質当量 + 糖脂質当量 +脂質過酸化物当量)=鮮度値 ・・(1)
(式2)
鮮度値 × 100 = 鮮度値% ・・(2)
(回帰式3)
鮮度値%= a×積算温度+b ・・(3)
(回帰式4)
過酸化脂質当量= a×積算温度+ b ・・(4)
2 コンピュータ
3 計測手段
