Opis:
Celem pracy było określenie zawartości związków fenolowych oraz aktywności przeciwutleniajacej gotowych do spożycia deserach dla niemowląt. Materiał do badań stanowiło sześć rodzajów deserów owocowych zakupionych w handlu detalicznym w 2008 roku, w których oznaczono zawartość suchej masy, zawartość związków fenolowych i poziom aktywności przeciwutleniajacej na podstawie zdolności wygaszanie wolnego rodnika ABTS∙. Największym udziałem suchej masy charakteryzował się mus z jabłek moreli i bananów (16,9%). Pod względem zawartości związków fenolowych wyróżniał się krem z jabłek i dzikiej róży (186,3 mg/100 g) oraz jabłuszka z owocami leśnymi (170,7 mg/100 g). Najwyższą aktywność antyoksydacyjną wśród deserów oznaczono w kremie z jabłek i dzikiej róży (14,2 μmol Trolox/g) oraz musie jabłkowym z brzoskwiniami (12,8 μmol Trolox/g). Pojemność przeciwutleniajaca pozostałych przecierów była nieco mniejsza i wahała się w granicach 11,4-11,7 μmol Trolox/g.
The aim of this study was to determine the content of phenolic compounds and antioxidant activity in ready-to-eat desserts for babies. The experimental material consisted of six kinds of fruit desserts taken from the market in 2008, in which the content of dry matter, phenolic compounds and antioxidant activity levels on the basis of free radical quenching ability ∙ ABTS were determined. The largest share of dry matter was found in apricot mousse with apples and bananas (16.9%). The largest amounts of phenolic compounds were found in the cream with apple and wild rose (186.3 mg/100 g) and apple with forest fruits (170.7 mg/100 g). The highest antioxidant activity among the desserts was determined in cream with apple and wild rose (14.2 μmol Trolox/g) and apple mousse with peaches (12.8 μmol Trolox/g). The antioxidant capacity of the remaining examined purée was slightly lower and ranged from 11.4-11.7 μmol Trolox/g.

Opis:
Introduction. Osteoporosis, the “quiet epidemic”, is one of the most serious threats to public health. It is known that estrogen plays a significant role in the regulation of bone turnover, and its loss at menopause causes osteoporosis. Added to this, insufficient calcium intake accelerates bone mass loss, increasing the risk of fractures. Objective. The study aimed to answer the question whether a fructan-enriched diet could be helpful in preventing from disturbances in bone turnover caused by calcium restriction combined with ovariectomy-induced estrogen deficiency. The differences related to the kind of fructan and “matrix effect” of fructan action (form of addition) were also evaluated. Materials and method. The study was conducted using sham-operated (control groups) or ovariectomized (OVX) rats fed a calcium restricted diet. The treatment diets contained one of three fructan sources – Jerusalem artichoke, yacon and Beneo Orafti Synergy1 – added alone or as an ingredient of strawberry sorbet, all in the amount providing 8% fructans. Analyses of biological material included: serum Ca, Mg and P concentrations, alkaline phosphatase activity (ALP), osteocalcin (OC) and C-telopeptide degradation products from type I collagen (CTX). Densitometric parameters of femora were also assayed. Results. Among markers of bone turnover, the ALP activity depended both on the kind of fructan and the form of addition. The highest value was shown in the OVX group fed a low-calcium diet, whereas administration of diet enriched with Jerusalem artichoke led to an almost 50% decrease in the value of this parameter. Dietary fructans also lowered the OC level. Feeding rats with diet containing sorbet enriched in yacon or Jerusalem artichoke resulted in a decrease of CTX, compared to the diet containing yacon alone or fructan formulation in both forms No significant differences were observed in densitometric parameters between treatment groups. Conclusions. The obtained findings suggest that fructan administration with a calcium-restricted diet might exert a positive effect on bone turnover parameters. Regarding the form of their addition, it is possible that other constituents of sorbets contributed to the fructan action. It remains open whether this impact would be significant over a longer period of time.

Opis:
Introduction. Osteoporosis, a disease associated with ovarian hormone deficiency following menopause, is the most common cause of age-related bone loss. Although an optimal intake of Ca is vital – both bone accretion during growth and maintenance in adult life – a great percentage of the population consumes far below the recommended amounts of this mineral. On the other hand, there are evidences that fructans enhance not only Ca absorption, but bone calcium as well. Objective. In the knowledge that estrogen deficiency and insufficient Ca in the diet during postmenopause cause serious problems with resultant osteoporosis, the aim of this study is to assess the effects of a diet enriched in fructan-containing sources alone, or in the “strawberry matrix”, on the structure of bone in OVX rats under calcium hypoalimentation. Materials and method. Experimental animals were female Wistar rats, sham-operated or ovariectomized. The treatment with Ca-restricted diets also contained one of the sources of fructan (Jerusalem artichoke, yacon, Beneo Orafti Synergy1), in the amount providing 8% of fructans. Femur architecture of rats was assessed by tomography and Ca content by the AAS method. Results. Ovariectomy led to a significant decrease in femoral Ca content, total mineral content and bone density of rats. This study shows that a diet containing inulin-type fructan (especially as a component of strawberry product) improved bone quality (i.e. increase in Ca content in femur, total density in middle part of bone, as well as decrease of endosteal circumference) in OVX rats under calcium hypoalimentation. Conclusions. These findings suggest that a fructan-enriched diet could be potentially useful for postmenopausal osteoporosis. It is important to determine an optimal dietary level of fructan with the long-term goal of developing a dietary strategy in osteoporosis prevention.
