An Optical Reflectance Nondestructive Method for Studying Apricot Fruit Color

Abstract:

Fruit colour is a major quality attribute of apricots affecting perception of consumer of their maturity and eating quality and is a main factor of good price of fruits. The aim of this study is the objective estimation of fruit colour by the use of colorimetric tristimulus system CIE L*a*b*, CIE L*C*h. To this goal, fresh fruits from apricot varieties were analyzed by spectral measurement in reflectance. The color parameters (L*, a*, b*) of the fruits were evaluated by using a colorimeter Hunter Lab Mini Scan XE Plus with a special software that allowed the recording of the data and their processing. Spectral recordings in the visible wavelength range using reflectance mode were tested to obtain information on the fruit pigment content which is related to the ground colour of fruit. To establish fruit quality the measurement of soluble solids content and titratable acidity was made. Comparing the results obtained it was found that colorimetrical method could achieve characterization of fruit color, fruit quality control, and objective selection of high performance hybrid relying on maturity period with a view to optimal valorization. Likewise, this method is highly advatageous, as it nondestructive, it is not toxic and does not pollute environment and is very quickly. Keywords: CIELAB, apricot, color, nondestructive method
