Abstract:
PURPOSE: A method for manufacturing a color chart for determining maturation of red paprika is provided to maintain freshness of the red paprika during distribution and minimize loss rate. CONSTITUTION: A method for manufacturing a color chart for determining maturation period of red paprika comprises: a process of measuring epicarp redness or pigmentation rate on epicarp of red paprika; a process of grading the red paprika in five group based on epicarp redness; and a step of mixing colors based on the color of red paprika. The five groups comprises a first group having -9.5 to -5.7 of epicarp redness, a second group having -5.7 to 7.4 of epicarp redness, a third group having 7.4 to 17.4 of epicarp redness, a fourth group having 17.4 to 24.4 of epicarp redness, and a fifth group having over 24.4 of epicarp redness. The first to fifth groups has epicarp pigmentation rate from under 50%, 50% to 70%, 70% to 85%, 85% to 95%, and over 95%, respectively.
Abstract:
PURPOSE: A method and a color chart which determines maturity of Fuji apple are provided to determine the maturity based on a real picture according to the each step of the apple. CONSTITUTION: A maturity of Fuji apple is determined by connecting pigmentation rate of apple based on mature period of the Fuji apple. The outerior of the Fuji apple is classified by one to five steps according to the value of redness.
