Production, oxidation traits and health of dairy ewes fed diets supplemented with fungus myceliated grains.
2019
Mushrooms contain many bioactive compounds, mainly poly- and oligosaccharides, known to have benefits for human health. Polysaccharides from mushrooms exhibited immunomodulatory, antibacterial, antiviral, and antifungal properties, as well as antitumor activity. Furthermore, some mushrooms showed to have potent antioxidant properties due to the presence of phenolic acids, flavonoids, polysaccharides, carotenoids, ascorbic acid, and tocopherols. These beneficial properties of mushrooms bioactive compounds indicate their potential use as performance-enhancing natural feed additives for livestock animals. In this regard, the use of mushrooms and mushroom-derived products has largely been inves…

Interaction of fluoride ions with milk proteins studied by gel filtration
1992
The interaction of fluoride ions with the bovine milk protein a-lactalbumin, type 1 a-casein, (3-casein, and K-casein was studied at pH 6.6, 5.5 and 3.9. At pH 6.6 and 5.5 fluoride ions do not combine with any of these protein. However, at pH 3.9 they combine with a-lactalbumin.
The influence of somatic cell count on sheep milk composition and cheese-making properties
2005
Somatic cell count (SCC) is an important tool for monitoring intramammary infections in dairy cows. However, systematic generalization of this decision rule is not easy in small ruminants. Determination of SCC in sheep milk is important for the processors of milk (indicator of quality), for breeders (mastitis indicator) and could be useful for selection as well. SCC value can be affected by some non-infective factors such as breed, stage of lactation, parity, type of lambing, type of milking, etc. (Bergonier et al., 1994), as well the health status of the udder (Fruganti et al., 1985; Ranucci et al., 1988). In addition, EC Directive 92/46, which regulates the production and commercialisatio…
Równowaga długookresowa pomiędzy cenami w łańcuchu dostaw na rynku mleka
2019
Łańcuch dostaw żywności łączy działania, ze sfery pierwotnej produkcji rolnej (rolnika) aż do konsumenta. Obejmuje on producentów, dostawców, firmy transportowe, magazyny, sprzedawców hurtowych i detalicznych, organizacje usługowe oraz konsumentów. Poziomy cen w poszczególnych ogniwach łańcucha dostaw na rynku mleka, ale nie tylko, charakteryzują się cyklicznością. Celem artykułu jest zbadanie, na podstawie danych pochodzących z Głównego Urzędu Statystycznego, występowania długookresowych zależności pomiędzy cenami na rynku mleka w poszczególnych ogniwach łańcucha dostaw. W badaniach wspomnianych zależności pomocny będzie test na występowanie kointegracji Engle’a-Grangera. Zakres czasowy an…
Addition of milk or caseinophosphopeptides to fruit beverages to improve iron bioavailability?
2010
Abstract A study has been made of the influence of caseinophosphopeptides (CPPs) added to a fruit beverage versus milk based fruit beverages upon iron retention, transport and uptake, using a combined simulated gastrointestinal digestion/Caco-2 cell system. Grape concentrate, orange concentrate, and apricot puree were used for sample formulation. Eight samples were assayed with/without added Fe sulphate (3 mg/100 ml fruit beverage) and/or added Zn sulphate (1.6 mg/100 ml fruit beverage), with/without skimmed milk (11% v/v). The addition of milk to fruit beverages exerted a positive effect on iron retention, transport and uptake versus fruit beverages, and this effect was greater than that o…
In vitrobioaccessibility of iron and zinc in fortified fruit beverages
2009
Summary Iron and zinc bioaccessibility was estimated in the in vitro gastrointestinal digests of six different fortified fruit beverages (Fb) containing iron and/or zinc and/or skimmed milk (M). Solubility values can be used to establish trends in relative bioavailability of iron and zinc, as the first stage towards mineral bioavailability comprises solubility in the intestinal tract. FbFe, FbFeM and FbFeZnM samples showed iron bioaccessibility above 88%, differing (P < 0.05) from those of FbFeZn (53%). In turn, FbZn, FbFeZn and FbZnM samples presented higher zinc bioaccessibility (above 68%), differing (P < 0.05) from those of FbFeZnM (48%). The presence of milk-derived caseinophosphopepti…

Viscoelastic properties of acid milk gel as affected by fat nature at low level
2005
International audience; The viscoelastic properties of acid milk gels containing small amounts of different fats were investigated. Skim milk was reconstituted from ultra low-heat skim milk powder and emulsions made with 2% (v/v) sunflower oil, olive oil, groundnut oil, or anhydrous milk fat using a pressure homogenizer. Acidification at 20 °C for 14 h to pH ∼4.6 was achieved by adding glucono-δ-lactone to the emulsion. Stress relaxation testing enabled determination of the firmness and the solid-like properties, i.e., elasticity. Regardless of the physical state of the fat, emulsion gels exhibited higher firmness than fat-free gels, despite the low fat level used. The firmness of the gels …
Effects of heat treatment and acid-induced gelation on aroma release from flavoured skim milk
2010
Abstract Time dependent aroma release was studied in skim milk, heated skim milk as well as in acid-induced gels derived from them using static headspace – gas chromatography analysis. A variable order kinetic model was fitted to experimental data and was used to determine headspace equilibrium concentration and initial rates of release. When compared to water, retention in milk based matrices was increased for hydrophobic aroma compounds, while it was decreased for more hydrophilic volatiles. Acid gelation reduced the initial rate of aroma release by a factor varying from 2.0 to 3.8, depending on the compound. Positive deviation from the first order kinetics was observed and suggests that …
