| ABSTRACT: The objective was to evaluate commercial eggs quality after being subjected to a cleaning process and immersion in whey protein concentrate (WPC) as a function of storage time. The experimental design was completely randomized in a factorial 4x7, being four methods of treating shell (not cleaned and not coated with WPC, not cleaned and coated with WPC, cleaned and not coated with WPC, cleaned and coated with WPC and seven periods of storage (1, 7, 14, 21, 28, 35 and 42 days) for a total of 28 treatments, with five replicates of four eggs each. Quality parameters evaluated were weight loss of eggs (%), specific gravity (g/cm3), haugh units (HU), yolk index (YI) and potential hydrogen (pH) albumen. The storage period increase, regardless of the... |

| ABSTRACT: This study produced pectin microcapsules containing Lactobacillus acidophilus by external ionic gelation, followed by the adsorption of whey protein and pectin to form multilayers. The viability of free and microencapsulated lactobacilli was evaluated after in vitro exposure to gastrointestinal conditions. They were also assessed by heat treatment, and stability was examined at -18 °C, 5 °C and 25 °C for 120 days. Exposure to different pHs, simulating passage through the gastrointestinal tract, showed that treatment of the microcapsules with only pectin (LA/P0) and with one and two layers of whey protein (treatments LA/P1 and LA/P3, respectively), were able to protect Lactobacillus acidophilus , with microcapsules increasing the release of... |
