This study aimed to investigate the effects of using 1%, 3% and 5% pomegranate seed powder (PSP) on model system chicken meat emulsion (CME) quality parameters. For this purpose, the properties of the emulsion samples prepared using different amounts of PSP were compared with the control group prepared with 70% chicken breast meat, 18% chicken skin, 10% water, 1.5% salt and 0.5% sodium tripolyphosphate (STPP). Chemical composition, pH, emulsion stability, water holding capacity, cooking yield, and color were analyzed in emulsion samples. TBARs and peroxide values of the samples were determined on days 0, 3, 5 and 7 during storage. Use of pomegranate seed powder in emulsion formulation resulted a decrease in b* and a* values. At the same time, with the addition of pomegranate seed powder, there was no difference in the protein values of the raw samples and the moisture, ash and pH values of the cooked samples. It was also observed that pH values, water holding capacity and cooking efficiency of emulsions increased with the increasing levels of PSP. Both peroxide and TBARs values were lower in emulsion samples formulated with PSP on 7 d compared to the control group.

Patties were extended with gluten free flours (linseed flour: LF, coconut flour: CF and their combination: LC) at a level of 5%. Control sample (B) was formulated with the same level of breadcrumbs. Using gluten free extenders did not change the water holding capacity (WHC); however, improved cooking yield resulted (P<0.05). Similarly, LF, CF and LC patties had lower diameter reduction and thickness change compared to the control sample (P<0.05). Due to color differences between breadcrumbs and gluten-free flours, color values of patties were affected significantly by the extender type (P<0.05). LF patties had the lowest L* and b*, the highest a* values within all patty groups. Different trends were observed in TBARS values of patties during storage, but in any case, all patties had TBARS values lower than 2.0 mg MA/kg throughout the storage. No significant differences were observed in patties’ sensory properties.

Tavuk eti marinasyonunda ardıç (Juniperus communis L.) ekstraktı kullanımının etkilerinin araştırılması.

In recent years, there is in-creased awareness of con-scious consumers about the fact that foods they eat are related directly to their health. In meat industry re-search and development, studies have accelerated to formulate healthier meat products formulations using plant sources as additive, which are also expected to improve the functional properties of the product. Pectin is a water soluble fi-ber with a structural com-plexity that occurs naturally in the cell walls of fruits and vegetables, contributes to reducing the risk of can-cer, and has some health benefits. Gelation is the most unique property of pectin; it forms a gel in the presence of Ca2+ ions or sugar and acid. Pectin pre-sents good water and fat binding property. Therefore, it can be used as a gelling agent, film/coating, and emulsifier and in low-calorie meat products as fat and /or sugar substitution (dietary fiber), as a natural component contributes to phosphate substitution and medical delivery systems in meat products. In this paper, it was aimed to discuss the physico-chemical proper-ties, health implications of pectin and its potential ap-plications in meat products.
