This study investigated the influence of the consumption of hawthorn (Crataegus tanacetifolia) fruit vinegar (HFV), a fermented product, on meat quality and gut microbiota in broiler chickens under cyclic heat stress (HS). A total of 300 one-day-old male Ross 308 chicks were divided into six groups with five replicates of ten birds, following a 2×3 factorial design with two temperatures (24 and 35°C) and three HFV supplementing levels (0, 2, and 4 mL/L) after one-week acclimation. Broilers in the thermoneutral groups were kept at 24°C, while HS groups experienced 35°C for 8 hours daily from day 21. Feed and water were provided ad libitum under a 24-hour lighting program. HS increased breast pH, reduced b* color value, raised ΣSFA and ΣMUFA levels, and lowered ΣUFA and ΣPUFA ratios. Supplementing 4 mL/L HFV increased breast L* color value and ΣSFA level while reducing ΣUFA ratio. The 2 mL/L HFV dose decreased ΣMUFA and increased ΣPUFA levels. Overall, HFV supplementation improved meat quality and beneficially altered fatty acid composition in heat-stressed broiler breasts. These results suggest that HFV supplementation may be a practical natural additive for broilers under cyclic heat stress and provide new evidence regarding its combined effects on meat quality and intestinal microbiota.

Pudrası ve Probiyotik Bakteri Kullanımının Dondurmanın Probiyotik Raf Ömrü ve Kalite Özelliklerine Etkisi]
Gündoğdu, Engin; Ertem, Hatice; Çakmakçı, Songül
In this study, the effect of green tea powder (GTP) in ice cream production on the ice cream properties and viability of probiotic bacteria [Bifidobacterium animalis ssp. lactis (Bifidobacterium BB-12) (P)] was investigated. Four ice cream groups (Control, C: without GTP and P; Probiotic Control (PC): with P; P+1% GTP; P+3% GTP samples) were produced. Bifidobacterium BB-12 (P) was added at 108 cfu/mL. pH, overrun, color, first dripping time, complete melting time and sensory properties were carried out on the second day. P was counted at 2, 15, 30, 45, 60, 75 and 90 days of storage. Bifidobacterium BB-12 number of PC was 6.54 log cfu/g at the 90th day. Bifidobacterium BB-12 number of PC was 7.10 log cfu/g, P+1% GTP sample was 6.48 log cfu/g and P+3% GTP sample was 5.84 log cfu/g at the 75th day. Bifidobacterium BB-12 number of PC was 7.24 log cfu/g, P+1% GTP sample was 6.59 log cfu/g and P+3% GTP sample was 6.69 at the 60th day. Sensory properties and probiotic counts showed that P+1% GTP sample could be accepted as a probiotic ice cream until day 75. Hence, GTP could be successfully used as a functional ingredient in the production of probiotic ice cream.

Yuksel, Ferhat; Gurbuz, Melek
The aim of this study is to determine some physicochemical, textural, cooking and sensory characteristics of traditional Turkish homemade noodles enriched with apple fiber. Apple fiber was incorporated into the noodle dough formulation at three different concentrations (5, 10 and 20%). Dry matter contents of the samples were in the range of 91.80-92.93% and an increase in dry matter with the addition of apple fiber was determined. Protein contents of the samples were in the range of 8.817-9.909 % and decreased significantly (p<0.05) with the addition of apple fiber. Firmness value was determined to be 33.81 kg in the noodle sample enriched with 20% apple fiber while the firmness value of un-enriched one was 23.09 kg. Color characteristics were significantly affected from the apple fiber concentration (p<0.05). Generally, cooking properties of the samples increased significantly in the noodles with the enrichment of apple fiber (p<0.05). No significant difference was determined for the overall acceptability of samples (p>0.05). Results indicated that innovative noodles could be produced by using apple fiber.
