    Investigation effects of inulin degree of polymerization on compound chocolate quality
    (Wıley, 2021) Göktaş, Hamza; Konar, Nevzat; Sağdıç, Osman; Toker, Ömer Said
    This is the first study in which the effect of degree of polymerization (DP) (?10 and ?23) of inulin (6.00, 9.00, and 12.0/100 g) on main quality parameters (color, texture, water activity, sensory properties, and melting behavior) of compound chocolate's (CC) was investigated. According to the determined L* values, using inulin (12/100 g) with high DP resulted in more glossy samples (p < .05). Except ?h value, the melt ing parameters of CC were not affected. However, the hardness of samples (391.9– 587.1 g) was determined in a wide range. The CC samples including inulin with higher DP had higher aw values (p < .05). According to the results of sensory analysis, using low DP inulin (<12/100 g) has advantages when compared with higher DP inulin containing samples. As a result, DP is an important parameter for developing choco late enriched with inulin as a fiber source, prebiotic, and/or bulking agents. Novelty Impact Statement: This is the first study in which the effects of inulin de gree of polymerization (DP) and concentrations (6.00, 9.00, and 12.0/100 g) on the main quality parameters of compound chocolate were investigated. The effect of (DP) (?10 and ?23) of inulin on the main quality parameters of compound chocolate samples as color, texture, water activity, melting behavior, and sensory properties was determined.

    Using paprika extract in chocolate spread and white compound chocolate: effects on color stability and bioavailability
    (Springer, 2023) Goktas, Hamza; Baycar, Abdullah; Konar, Nevzat; Yaman, Mustafa; Sagdic, Osman
    White compound chocolate (CC) and chocolate spread (CS) do not contain cocoa solids and thus they have deficiency of antioxidant activity. So, paprika extract (PE) was used to develop the visual and functional features of compound chocolate (CC) and chocolate spread (CS). Color stability of both chocolate samples was investigated for 12 weeks under accelerated shelf-life conditions and using PE significantly increased + a*, C*, and h degrees values of chocolate samples (P < 0.05). Also, at the end of shelf life, Delta E values were determined as > 2.83 and > 3.74 for CC and CS samples, respectively. Using PE in the production of CC and CS samples significantly increased antioxidant activity for pre-and post in vitro digestion, except for post digestion of S025 samples (P < 0.05). General acceptability of the CS samples decreased with increasing of PE ratios, for CC samples it was increased except for C100. The results showed that PE can be used in the production of functional chocolate with high antioxidant activity and as a natural coloring agent.
