Influence of the Dose and Length of Wheat Fiber on the Quality of Model Sterilized Canned Meat Products [PDF]

Foods, 2020
The aim of this study was to evaluate the quality of model homogenized sterilized canned meat products produced with wheat fiber preparations (WF 200 R or WF 600 R) with different fiber lengths used in the amount of 3% or 6% by weight of the batter. Basic chemical composition (water, protein, fat, collagen and salt content), pH level, water activity ...
