Abstract Objective To investigate the relative importance of specific health knowledge and taste on acceptance Brassica vegetables (broccoli, red green cabbages, broccolini, cauliflower, Brussels sprouts). Design In a sample adults all reporting medium–high physical activity (as marker/control behaviour) either low (≤2 portions/d) or high (≥3 vegetable intake, half those with consumption (Li group) (Hi received cancer protection information, while other did not (Ln Hn groups), before hedonic...
Abstract BACKGROUND: Diets high in fruit and vegetables are known to have significant health benefits. This is part due the presence of phytochemicals, which possess potential protective study focuses on ability strawberries be bred for higher anthocyanin content. a major contributor characteristic colour nutritional value ripe strawberries, together with phenolic acids, ascorbic acid total antioxidant capacity. RESULTS: Anthocyanins five commercial strawberry cultivars three breeding lines...
Vitamin D deficiency is widespread, affecting over 30% of adult Australians, and increasing up to 80% for at-risk groups including the elderly (age>65). The role in development central nervous system supported by association between incidence neurological psychiatric disorders Alzheimer's disease (AD). A reported positive relationship status cognitive performance suggests that restoring might provide a benefit those with deficiency. Mushrooms are rich source ergosterol, which can be...
This study investigated the effect of germination and fermentation on composition carbohydrates in Australian sweet lupin. Specifically, amount sugars (sucrose, fructose, glucose), starch, oligosaccharides (verbascose, stachyose, raffinose), dietary fiber were measured germinated lupin seeds fermented flour, compared with those soy. High performance liquid chromatography coupled refractive index was employed for quantitation sugars, oligosaccharides, gas a flame ionization detector used...
Kakadu plum (Terminalia ferdinandiana Exell, Combretaceae) and Illawarra (Podocarpus elatus Endl., Podocarpaceae) extracts were fractionated, using a bioassay-guided approach screened for antioxidant activity [oxygen radical absorbance capacity (ORAC) cellular (CAA) assays] antiinflammatory (nitrite concentration prostaglandin E(2) release in lipopolysaccharide (LPS)-activated murine macrophages). Among 8 fractions obtained from KP 5 IP, fraction KPF5 exhibited superior all assays, with an...
The consumption of mushrooms has been linked with protection against dementia, including Alzheimer's disease (AD), by several biological pathways inhibiting beta-site APP-cleaving enzyme (BACE1), which is responsible for releasing toxic β-amyloid peptide in the brain. We have investigated capacity medicinal mushroom species−Auricularia polytricha (wood ear mushroom), Agaricus bisporus (button Flammulina velutipes (winter or enoki and Lentinus edodes (shiitake mushroom)−in regulation BACE1....
ABSTRACT In recent years, there has been intense interest in the potential health benefits of dietary derived plant polyphenols and antioxidants. A new variety Prunus salicina, Queen Garnet plum (QGP), was developed as a high anthocyanin, antioxidant plum, Queensland Government breeding program. Following consumption 400 mL QGP juice (QGPJ; 1,117 mg anthocyanins) by two healthy male subjects, anthocyanins (cyanidin-3-glucoside cyanidin-3-rutinoside) were excreted mainly methylated...
Abstract Date ( Pheonix dactylifera L.) seeds are a valuable and abundant by‐product with various potential food applications. Free polyphenols (FPPs) bound (BPPs) of date from Deglet Nour variety grown in Australia were investigated using high‐performance liquid chromatography‐mass spectrometry. The FPP fraction contained the following main phenolic compounds per gram seed powder; procyanidin B1 (499.8 ± 7.8 μg), B2 (288.6 6.1 catechin (167.6 2.1 epicatechin (39.44 0.39 protocatechuic acid...
Chemical and sensory characterisation of whole fractionated myrosinase-free extracts from selected Australian-grown, raw Brassica vegetables (broccoli, cauliflower, Brussels sprouts red cabbage) was carried out to determine the contribution key phytochemicals (i.e. glucosinolates, free sugars, phenolics) taste profiles these vegetables. Glucosinolate (GS) phenolic were determined by liquid chromatography coupled with photodiode array detection mass spectrometry. Ten glucosinolates quantified...
Scope Whey protein isolate (WPI) contains vitamin B 12 and folate. However, the efficacy of WPI as a bioavailable source these vitamins in elderly with low was not previously tested. We investigated effects supplementation on folate status blood measured changes homocysteine (HCY), methylmalonic acid (MMA), genome integrity biomarkers individuals status. The effect compared to soy (SPI). Methods results In this randomized controlled cross‐over intervention trial, 56 subclinically ‐deficient...
Abstract A relationship between the fibre coating/gas phase partition coefficient ( K fg ) of terpenoids and their linear temperature programmed retention index (LTPRI) was derived using a group selected monoterpenoids (with LTPRI's ≤ 1124). The accuracy this tested by comparing calculated experimentally measured values for same 13 compounds, including monoterpene hydrocarbons, alcohols ethers. good agreement two (RSD 11%) found most even when BPX‐5 GC column used determination LTPRI values....
Abstract Numerous in vitro studies using solvent or aqueous extracts of raw dietary plant material have demonstrated modulation colon cancer cell growth and apoptosis effects on immune nonimmune pathways inflammation. We developed a generic, 3-staged food-compatible process involving heating for conversion plants into food ingredients report results potential cancer-regulating properties processed forms Bay leaf (Laurus nobilis). In inhibition by products HT-29, HCT-116, Caco-2, SW-480 human...
