“…Sulphuring did not influence the sorbitol content. Its level was considerably higher than in apricots grown in other countries (Forni et al, 1997;Dolenc-Sturm et al, 1999;Katona et al, 1999), reaching about 23 g/100 g dry matter (Table 2), confirming this to be a characteristic of Malatya apricots (Akin et al, 2008). It is reported that sugar alcohol sorbitol is more beneficial than other sugars with regard to dental health and diet control, because the different metabolism of sorbitol in comparison to other sugars results in lower energetic input to the body, and it improves the taste and texture of fruits (Akin et al, 2008).…”

IntroductionDrying is one of the oldest preservation techniques for foods and is the most important process in the successful storage of apricots (Göğüş et al., 2007). The objective in drying apricots is to reduce the moisture content to a level that allows safe storage over an extended period. In Turkey, the most common drying method for apricots is open-air sun-drying, requiring low capital, simple equipment, and low energy input (El Halouat and Labuza, 1987;Gezer et al., 2003). Generally, the fruits are spread on rooftops or on rocks without subjecting them to any pretreatment or washing with water (Mir et al., 2009). To decrease the effect of spoilage reactions, to facilitate the drying process, to prevent browning, to ensure colour stability, and to improve the overall product quality, some pretreatments are advised. One of these treatments is sulphuring

“…However, identification of minor components such as lysine remained unreliable at that time. Derivatization conditions for metabolite profiling were optimized by selecting 12 compounds representative of plant primary metabolism (Adams et al, 1999), and were applied to profile polar organics (sugars, polyols, acids and amino acids) in apricots (Katona et al, 1999). These techniques were used more systematically to analyse the number of metabolites involved in potato tuber primary metabolism by evaluating recovery rates using spiking experiments and external calibration curves (Roessner et al, 2000).…”

Metabolites are the end products of cellular regulatory processes, and their levels can be regarded as the ultimate response of biological systems to genetic or environmental changes. In parallel to the terms 'transcriptome' and 'proteome', the set of metabolites synthesized by a biological system constitute its 'metabolome'. Yet, unlike other functional genomics approaches, the unbiased simultaneous identification and quantification of plant metabolomes has been largely neglected. Until recently, most analyses were restricted to profiling selected classes of compounds, or to fingerprinting metabolic changes without sufficient analytical resolution to determine metabolite levels and identities individually. As a prerequisite for metabolomic analysis, careful consideration of the methods employed for tissue extraction, sample preparation, data acquisition, and data mining must be taken. In this review, the differences among metabolite target analysis, metabolite profiling, and metabolic fingerprinting are clarified, and terms are defined. Current approaches are examined, and potential applications are summarized with a special emphasis on data mining and mathematical modelling of metabolism.

“…In particular, trimethylsilyl derivatives (TMS) are used for the clinical analysis of acid metabolites formed in organisms in a group of genetic disorders. [15][16][17] In the TMS form, phenols and phenolcarboxylic acids are determined in plants, [18][19][20][21] in wines [22][23][24] and in vegetable oils. 25,26 Retention indices of TMS derivatives of many important biochemical aliphatic and aromatic acids have been reported in these articles.…”

GC Identification of Organic Compounds Based on Partition Coefficients of Their TMS Derivatives in a Hexane-Acetonitrile System and Retention Indices

This paper reports the experimentally determined and calculated partition coefficients (Kp) in a heterogeneous system consisting of two partially mixing organic solvents for trimethylsilyl derivatives of 119 compounds including phenols, phenolcarboxylic acids, mono-and dicarboxylic acids, and some carbohydrates and polyols. It was demonstrated that a simple model based on the available physico-chemical properties of molecules can be used to accurately predict the hexane-acetonitrile partition coefficients. Phenols, other organic acids, and carbohydrates form complex mixtures in extracts of plant tissues, in various biological fluids, as well as in waste waters. For group identification of these mixture components, it is desirable to use the parameter j which is a combination of Kp and gas chromatographic retention indices: j = kI -log Kp. This approach increases identification reliability in gas chromatographic analysis. The use of the group parameter j in the analysis of nonvolatile organic components of waste waters is reported.
