A unique solution to automatically measure color and lycopene in tomatoes.

COLOR INDICES / LYCOPENE

• Capable to calculate color and lycopene content
• Measurement of the sample as it is
• Quick results
• Calibration with standard BCR tile
• Software for data analysis

The Maselli LC01 Colorimeter + Spectrophotometer is a laboratory instrument developed to measure the color indices a, b, a/b and L, as well as the Lycopene content in tomato products. It has been designed to be accurate, robust and simple to use: the stainless steel enclosures and waterproof display permit the LC01 to also be used in the processing area The LC01 is able to quickly measure the sample as it is introducing a new innovative method to measure directly the lycopene content of the tomatoes during each stage of the processing. An intuitive software and touch-screen display simplify the interface for all the operations related to graphics, data storage, transfer and printing features. While the equipment does not need frequent calibration, it can be checked using the classic tomato standard BCR red ceramic tile, while using its PVC sample holder with optical glass window for the measurements.

Automatic system designed to assess quality control parameters of incoming tomatoes directly from the truck in the fruit receiving area.

QUALITY CHECK OF THE INCOMING TOMATOES

• Turn key solution
• More than 200 installations worldwide
• Robust sampler
• Fully automatic cycle (5 minutes / truck)
• Software for data analysis

The SV01 station is installed at the receiving area of the tomatoes processing plant to evaluate the quality of the incoming raw fruit. The station is a turn key modular construction which consists of a truck sampler, a prefabricated module with all the elements for the check of the tomatoes and a PC handling automatically the whole system. All the cycle is very quick and only one operator can process 1 load every 5 minutes making it easy the circulation of the trucks into the factory. Each plant may personalize the software with the parameters to be checked: in average, the system is determining the percentage of waste (inerts, fruit defects, fruit illness) and the physical parameters such as Bx, pH, color and lycopene. The data gathered, which may be printed and stored in a database, not only provides a more accurate economical evaluation of the delivered fruit, but also makes it possible to send the various loads to the most appropriate processing lines and can be used to help with the making of agronomic decisions for the cultivation of the fruit in the coming years.
