Present a mechatronic system having able to determine the concentration of carotenoids

Civilization besides its major advantages (undisputed) brought us some unhealthy habits which unfortunately have managed to penetrate deeply within several generations on the current planetary populations producing great damages to its health. Perhaps it would be the right time to and more people learning to live healthy, to feed ourselves healthy, let's try to break the chain of evil which we grind all already several generations. It has been shown that residual free radicals in the body are responsible for aging. The role to annihilate them is fulfilled by the antioxidants. Antioxidants are a group of compounds produced by the organism or that occur naturally in many foods. Antioxidants work together in the human body to maintain health and vigor, especially during the last decades of life. Antioxidants network offers the advantage of avoiding premature death caused by these deficiencies and sometimes even cure those diseases. The methods generally used for the determination of carotenoids extracted from a natural environment are based on absorption spectrophotometry. These methods may be relatively precise but require a relatively long preparation of the sample to be analyzed. Indeed, because of the other pigments often present in the samples analyzed and extracted at the same time as the carotenoids, the analysis is not very precise on the crude acetone extract, chlorophylls in particular are often troublesome. Saponification and different extraction methods are then necessary to purify the solution, which inevitably leads to loss of carotenoids, thus an error in the assay.
