The main objective of the current study was to use a by-product from the deboning process of poultry meat and use it to produce products with high nutritional value. Four product assortments (chicken and turkey soup concentrate and chicken and turkey stock respectively) were produced using bone tissue of the two species as biological material. It was found that there were no significant differences in the technological process to obtain them, the most varied differences being evident in the raw chemical composition, where chicken broth concentrate had the highest percentages of water (69.5%), protein (20.1%) and collagen (18.2%) compared to chicken stock where a higher rate of fat (17.6%) was evident. In the case of turkey backbone products, the highest percentage of fat was found in the concentrated broth, with the stock having the highest percentages of water (65.2%), protein (18.8%), and collagen (17%). The color characteristics are closely related to the Maillard reaction resulting from the cooking operation of the biological material, resulting in products with a positive sensory appearance and microbiological safety.

Following the slaughtering and processing of animals for meat, only one-third of them is meat, while the remainder consists of byproducts and waste, which need to be processed and utilized appropriately. Industrial byproducts constitute costly losses for these industries and pose challenges in their eco-friendly disposal. These costs can be offset through innovation to generate value-added products that increase profitability. Efficient utilization of byproducts has a direct impact on the economy and the environment. This study explores the potential to create collagen-rich bone broths and to this end, four batches were developed, two made from bones sourced from adult cattle and two from bones sourced from juvenile cattle. These were analyzed physicochemically and microbiologically to characterize them qualitatively. The findings suggest that both types of bone broths offer significant nutritional value, with variations influenced by the age of the cattle and the vegetable additions, as evidenced by highly significant differences (p < 0.001) among batches obtained through statistical processing. These findings underscore the importance of efficiently exploiting resources and the potential to develop valuable food products from seemingly residual sources. [ABSTRACT FROM AUTHOR]
