A high-intensity spectrophotometer interfaced with a computer for food quality measurement

ABSTRACT WE have built for use in our labora-tory a high-intensity, low stray-light spectrophotometer which measures the density of products such as cantaloups, apples, and tomatoes. The spectropho-tometer is a dual monochromator con-figuration; the sample to be analyzed is placed between the two monochroma-tors. The computer controls and collects the data from the spectrophotometer and also provides oscilloscope display and other manipulation of the data.
