Effect of Partial Replacement of NaCl with Salty Pig Bone Peptides on the Quality and Flavor of Low-NaCl Sausages
The objective of this study was to investigate the feasibility of partially replacing NaCl with salty pig bone peptides(SPBP)in the production of low-NaCl sausages(LNS).The impact of varying proportions of SPBP replacing NaCl on sensory attributes,texture characteristics,color variation,pH,yield,moisture content,taste,and volatile profile was examined.The findings indicated that sausages supplemented with 1%NaCl+l%SPBP(1%LNS-SPBP)outperformed the control(supplemented with 2%NaCl)in terms of color,appearance,taste and flavor,while tissue structure was comparable to that of the control group.Additionally,1%LNS-SPBP significantly enhanced the textural properties of LNS(P<0.05).E-tongue results demonstrated that the salty,freshness,sweetness,and richness attributes of 1%LNS-SPBP surpassed those of the control and other experimental groups,while sour,bitter and bitter aftertaste were notably reduced compared to the control group.However,the sausage yield and moisture content were significantly(P<0.05)diminished when different percentages of SPBP were applied.Furthermore,HS-GC-IMS analysis revealed alterations in the volatile profiles of LNS,and in combination with the results of the sensory scores,a certain amount of SPBP in place of NaCl conferred a better flavor to LNS.In conclusion,the combination of 1%LNS-SPBP effectively substituted 2%NaCl,achieving the objective of reducing salt content without compromising saltiness in LNS.
