It is possible for humans and animals alike to be contaminated with mycotoxins such as ergot alkaloids, aflatoxins, ochratoxins and fusariotoxins. Aflatoxins are evaluated as strong carcinogens but their real occurrence and importance seems to be low in Europe. Ochra toxin A has become notorious mycotoxin especially in northern parts of Europe. Nephropathies are considered to be induced by ochratoxins...
The effect of the Panax ginseng powder extract on reproduction, growth, renal and liver functions and some blood biochemical indices of Japanese quails were investigated. Panax ginseng powder extract at 2 mg and 4 mg/bird daily increased egg number per hen, average egg weight and hatchability. It slightly improved the efficiency of feed utilization and increased the levels of serum total protein,...
Six most commonly known models for predicting thawing time of food: Nagaoka's et al., Cleland's et al., Calvelo's, Pham's and Piotrovich were compared when testing Tylose MH 1000 test substance, ground beef, and potato, and relative errors, regression and variance. The Cleland's et al. method, disregarding equivalent heat transfer dimensionality (EHTD) and mean conducting path (MCP) coefficient, was...
Our objective was to evaluate the influence of pH values on the microcoagulation process of whey protein concentrate and whey protein isolate, and obtaining a solid fat mimetics. Such substances were obtained in a precise pH condition. Differences in pH values at which fat mimetics can be obtained are caused by differences in composition of the WPC and the WPI, and particularly, by different lactose...
The review shows recent dynamics and directions of methodological development in multidisciplinary area of sensory analysis of food interfaced with consumer preferences and acceptance measurements. Impact of increasing knowledge of physiology and psychology of sensory perception as well as availability of advanced multivariate statistical techniques for data processing has been stressed. Applicability...
This study investigated the influence of four Lactobacillus acidophilus strains (B, V-74, CH-2 and CH-5) and their mixtures on the viability of Escherichia coli NCTC 8196 and Staphylococcus aureus NCTC 4163 in fermented milk stored at 7°C for 21 days. With no L. acidophilus present, both E. coli and S. aureus remained viable with more than 108 cfu/mL. In the presence of L. acidophilus, no detectable...
There is relatively little information concerning the bioavailability of thiamine from food products; nevertheless available data on thiamine show that this vitamin is a significant factor that plays an important role in their nutritional status. The bioavailability of thiamine depends on several factors of which food and diet composition appears to play a paramount importance.
The research was taken up in the aim of comparing daily food rations nutritional value for people snacking or not snacking from two age groups: youth (13-15 years old, 124 persons) and students (19-26 years old, 190 persons). Among all analysed sub-groups, there were people snacking or not snacking. Nutritional value of food consumed by young people in daily food rations (DFR) and snacking (S) was...
Porcine and bovine semimembranosus muscles were examined after, respectively, 24 h and 96 h from slaughter. The muscles were pressurised at 200, 300 and 400 MPa for 10 min. The pH value, pressure-induced drip, ability to hold free- and added water, and thermal drip were analysed. The pH values for muscles were found to increase with pressure. Pressurization at 200 MPa caused the greatest drip of meat...
