| ABSTRACT: This study aimed to investigate the extraction and characterization of protein concentrates from pig by-products (heart, liver and kidneys) using the pH-shifting technique. From the solubility profiles (pH 2 to 12), the protein extraction was performed at alkaline pH (10.0 to 11.5), obtaining two fractions: soluble (SC) and insoluble (IC). Higher protein content (71 to 77%) and extractability (214 to 459 mg/g) were observed in heart and liver concentrates; whereas, for water holding capacity (WHC) the highest values (4.20 to 4.54 g water/g protein) were for the heart (SC) and kidney (SC and IC) concentrates. All concentrates had high emulsion stability and higher WHC than commercial protein extenders (whey and soybean). The concentrates obtained... |

| ABSTRACT: In order to improve nutritional and functional quality, chicken burgers were made with different amounts of chia seed (0, 2, 4 and 8%) as pork fat replacers and evaluated for the microbiological, technological and sensorial characteristics. The proximate composition and the microbiological characteristics of raw burgers were in accordance with Brazilian legislation. Higher additions of chia increased the amount of dietary fiber (up to 1.46%) and carbohydrate in the products and reduced the fat content by up to 29%. The addition of chia seed reduced the a* values and increased the h* values of the raw burgers and reduced the tenderness and degree of lipid oxidation in the cooked burgers. Lower sensory taste scores and overall acceptance were... |
