The use of fermented minced fish with probiotics in the recipe composition of dry-cured sausages
Abstract
The paper analyzes the effect of using fermented minced fish (FMF) with the L. plantarum probiotic in the formulation of dry-cured sausages on the quality characteristics of the finished product in comparison with sausages based on unprocessed minced fish. The microbiological, physico-chemical, structural-mechanical and organoleptic properties of the product have been evaluated. The results have shown that dry-cured sausage samples with FMF had a higher content of probiotics (2.5×108 CFU/g) compared to the control sample (6.3×106 CFU/g), which allows a person to fully meet the daily requirement in probiotics with just through the use of 40 g of such a product. The use of FMF in the dry-cured fish sausages provides a safe pH value (5.21) and significant increase in total acidity (1.39 %) compared to the control sample (pH – 6.80 and total acidity – 0.45 %). It has been established that using FMF in the technology of dry-cured fish sausages can reduce the time of their manufacture by increasing the average rate of dehydration of the product. It has been determined that samples of dry-cured sausages with FMF have higher values of hardness and cutting force. A comprehensive assessment of the quality of sausages with FMF has shown good results – 76.85 % of the maximum possible level. Thus, the possibility of using FMF with L. plantarum in the manufacture of dry-cured sausages has been determined. The proposed method makes it possible to obtain a product with a high protein content (32.31 %), enriched with L. plantarum probiotics, having a low pH value and a peculiar sour-milk taste and aroma. Based on the results of the study, normative and technical documentation for this type of product has been developed and approved.
