Nondestructive measurement of fresh tomato lycopene content and other physicochemical characteristics using visible-NIR spectroscopy.
Measurement of fresh tomato fruit overall quality, and particularly lycopene content, is challenging in the context of high-volume production. An experiment was conducted to simultaneously measure various quality parameters of tomato in a nondestructive manner using vis-NIR reflectance spectroscopy and chemometrics. The sampling set included different cultivars that are obtainable from both ret...
متن کاملA rapid spectrophotometric method for analyzing lycopene content in tomato and tomato products
Lycopene is a carotenoid that has antioxidant properties and imparts the red pigment in some fruits and vegetables. Tomato (Lycopersicon esculentum Mill.) is one of the predominant lycopene sources in a typical North American diet. Current methods to assay lycopene content in fruit are time consuming, expensive, and use hazardous organic solvents. Here, we report a method by which light absorba...
متن کاملAntioxidants Content in Empetrum nigrum Fresh and Dried Fruits
Empetrum nigrum L. (crowberry or black crowberry) belongs to Ericaceae (Empetraceae) family and is a circumboreal species, including both arctic and alpine environments as well as temperate and sub-arctic climates. The species is divided into two subspecies, whether is a plant produces hermaph-roditic flowers (E. nigrum ssp. hermaphroditum) or is dioecious (E. nigrum ssp. nigrum). There is curr...
متن کاملDetermination of carotenoids in tomato juice by liquid chromatography.
A high-performance liquid chromatography method was developed to determine the various carotenoids in tomato juice. A C30 column and a mobile phase of acetonitrile-1-butanol (7:3, v/v) (A) and methylene chloride (B) with the following gradient elution were used: 99% A and 1% B intitally, increased to 4% B in 20 min, 10% B in 50 min and returned to 1% B in 55 min. Sixteen carotenoids, including ...
