ANALYSIS OF THE TRACE ELEMENT CONTENT OF GRAPE MOLASSES PRODUCED BY TRADITIONAL MEANS

Abstract

Molasses, sugar and other food additives, such as without adding any substance, concentrated by boiling and shelf life is a long concentrated product. Molasses is an important food for humans in terms of mineral content and high energy content. Grape fruit is considered as a rich food source with strong health effects. Grape fruit generally contains 70-80% water, 15-25% carbohydrate and small amount of minerals, amino acids, phenolic compounds. Heavy metals are highly toxic elements, which can severely influence plants and animals and have been involved in causing a large number of afflictions. Heavy metals in the environment are non-biodegradable and ubiquitous, it can cause serious human health hazards and momentous ecological effects through food chain's bioaccumulation. Inorganic micro-pollutants are of important concern because they are non-biodegradable, highly toxic and have a probable carcinogenic influence. In this study, it was aimed to determine the heavy metal levels in grape molasses collected from the villages of Karaman and to emphasize the importance of nutrition in carob molasses. The samples were prepared to be 2 parallel for each sample and were solutioned by wet burning method. The concentrations of the determined elements were determined by Flame Atomic Absorption Spectrometry (FAAS). Traditional produced grape molasses are determined by comparing metal contents with each other and with standard values.
