Applying egg protein hydrolysates to production of model processed meat products


The objective of this study was an attempt to apply protein hydrolysates of egg-yolk and egg-white, as well as a protein hydrolysate of quail egg mass to produce model processed meat products and to assess their effect on the technological parameter, texture, and colour of experimental products. The stuffing containing pork meat, backfat, and egg protein preparations were thermally treated in a water bath (up to 72 °C in the geometric centre of the sample) and stored for 24 hrs under the refrigeration conditions (2 °C ± 1 °C). In the final products obtained, the thermal drip and the production yield were analysed, the texture profile was determined as were the colour components using an CIE L*a*b* system. Based on the study results obtained, it was found that the addition of protein hydrolysates of egg-yolk and quail egg mass had no effect on thermal loss quantity, but it contributed to the increase in the product yield of the model processed meat products. The values of textural parameters of the experimental products, i.e. the hardness, cohesiveness, springiness, chewability, and gumminess significantly differed depending on the type of the preparation used and on its amount. The similar tendencies were reported during the colour analysis of the ready meat products. It was found that those experimental meat products had a more intensive hue of the red colour, which constituted the production variant with a protein hydrolysate of egg white used.
