Turkish Journal of Chemistry

The saturated cyclo-hydrocarbons CnH2n (n = 3–7) were constructed by the iterative coupling of the structural unit groups (SUGs), specifically the SUG-CH2C2 fragment, which was previously established for molecular basis optimization. For the McLean–Chandler 6-311+G basis set, under the SUG perturbation, the outer (s′, p′) and diffuse (sʺ, pʺ) primitive Gaussian type orbitals for the core-atom C* of SUG-CH2C2 undergo an off-center spatial displacement into a twinning configuration. Specifically, the s-type twins (s′, sʺ) share identical Gaussian exponents and are symmetrically shifted toward the two neighboring carbon atoms, while the p-type twins (p′, pʺ) exhibit a matching configuration. Generally, this …

Valorization Of Buttermilk As A Functional Ingredient In Yogurt Soup: Effects On Physicochemical Properties, Aroma Profile, Amino Acid Composition, And Bioactivities, Emi̇ne Maci̇t, Fatma Zehra Özyilmaz

Turkish Journal of Agriculture and Forestry

​In this study, the feasibility of using buttermilk as a functional ingredient in yogurt soup, a traditional fermented dairy product, was investigated with the aim of valorizing dairy industry by-products. Soup samples prepared with different buttermilk ratios (0%, 25%, 50%, 75%, and 100%) were evaluated for their physicochemical and sensory properties, aroma and amino acid profiles, antioxidant capacity, and antidiabetic activity. The incorporation of buttermilk resulted in statistically significant differences in total solids, ash, and titratable acidity (p < 0.01 and p < 0.05), while no significant changes were observed in fat, protein, or pH values. Increasing buttermilk levels led to higher L* and b* values and lower a* values. Sensory analysis showed that flavor scores increased with buttermilk content, with the highest score observed in the sample containing 100% buttermilk (T5). In the control sample, hexanoic acid, benzoic acid, acetic acid, methyl salicylate, and several ketones were identified as dominant aroma compounds, whereas buttermilk-enriched samples were characterized mainly by hexanoic acid, acetic acid, butanoic acid, ethyl acetate, higher alcohols, and ethanol. Increasing buttermilk content resulted in a higher proportion of alcohols and a reduction in acids, ketones, and aldehydes. Samples with higher buttermilk levels exhibited increased essential amino acid content, while functional amino acids such as γ-aminobutyric acid, β-aminoisobutyric acid, ethanolamine, proline, and alanine reached their highest levels in the T5 sample. The T5 sample showed a DPPH radical scavenging activity of 5.98%, whereas the highest α-amylase inhibition was observed in the control sample. Overall, the results indicate that buttermilk can be effectively used as a functional ingredient in yogurt soup formulations, improving nutritional quality and sensory characteristics.
