Nutritional quality and sensory acceptability of complementary food blended from maize (Zea mays), roasted pea (Pisum sativum), and malted barley (Hordium vulgare)

Complementary weaning foods can be improved by blending of different locally available food grains. Optimum nutrient quality was found in the range of 55.0–68.5% maize, 27.5–35.0% pea, and 4–10% malt barley. Thus, the model generated in study can predict other proximate attributes except for fat.

Effects of pretreatments of banana (Musa AAA,Omini) on the composition, rheological properties, and baking quality of its flour and composite blends with wheat flour

The effect of chemical and heat pretreatments on the proximate and functional properties of flour from the pretreated bananas and its composite with wheat flour (WF) were examined. Water absorption and specific volume were 48.12 ± 0.07–52.60 ± 0.14 and 2.850 ± 0.07–5.635 ± 0.18 with the WF having significantly (P < 0.05) higher values than other blends and the most acceptable in terms of appearance and taste.

Genistein suppresses the proliferation of telomerase-negative cells

In this study, we tested genistein, a TOP2 inhibitor, on the repression of telomere–telomere recombination. The results indicated the inhibitory effects of genistein on telomerase minus cells depend on type II recombination pathway in yeast and the alternative lengthening of telomere (ALT) pathway in human tumors.

Euglena gracilis paramylon activates human lymphocytes by upregulating pro-inflammatory factors

The aim of this study was to verify the activation details and products of human lymphomonocytes, stimulated by different β-glucans, that is Euglena paramylon, MacroGard®, and lipopolysaccharide. Our results indicate that linear fibrous Euglena β-glucan, obtained by sonication and alkaline treatment can act as safe and effective coadjutant of the innate immune system response.

Removal of cadmium from contaminated Lentinula edodes by optimized complexation and coagulation

Heavy metal pollution is a serious problem in Lentinula edodes because it tends to accumulate heavy metals. This study investigated the removal of cadmium (Cd) from contaminated Lentinula edodes and its lentinan by complexation and coagulation. An optimized method for acquiring purified lentinan from contaminated Lentinula edodes was constructed, which affords a method for extracting pure, active ingredients from polluted food or medicinal sources.

Antioxidant potential of Juglans nigra, black walnut, husks extracted using supercritical carbon dioxide with an ethanol modifier

Walnuts have health benefits due in part because of their antioxidant content. Supercritical carbon dioxide with an ethanol modifier can extract antioxidants from walnut husks. The highest antioxidant content measured by the ferric reducing ability of plasma (FRAP) assay was 0.054 mmol Trolox Equivalent/g of husk.

Blanching influences the phenolics composition, antioxidant activity, and inhibitory effect of Adansonia digitata leaves extract on α-amylase, α-glucosidase, and aldose reductase

The influence of blanching on the phenolics composition, antioxidant activity, and inhibitory ability of methanol extract of A. digitata leaves on the activities of some key enzymes implicated in the pathology and complications of type 2 diabetes (T2D) was evaluated in vitro. The raw leaves had appreciable levels of health-benefiting flavonoids and phenolic acids, displayed antioxidant activity and inhibited some key enzymes implicated in the pathology and complications of T2D. However, blanching decreased these functionalities of the leaves.

The relationship between agricultural biodiversity, dietary diversity, household food security, and stunting of children in rural Kenya

Data indicate that households with children with stunted growth and those without are significantly different in dietary diversity score and household food insecurity access scale but not with agricultural biodiversity. This suggests some potential in using dietary diversity score and household food insecurity access scale as proxy measures for stunting.

A nutritional supplement containing lactoferrin stimulates the immune system, extends lifespan, and reduces amyloid β peptide toxicity in Caenorhabditis elegans

We determiend that a lactoferrin-based product protected against acute oxidative stress and extended lifespan of Caenorhabditis elegans. Paralysis of the transgenic C. elegans strain CL4176, caused by Aβ1-42 aggregates, was clearly ameliorated by treatment. Transcriptome analysis in treated nematodes indicated immune system stimulation, together with enhancement of processes involved in the oxidative stress response, protein homeostasis processes, cellular adhesion processes, and neurogenesis in the nematode.

Effect of different salt and fat levels on the physicochemical properties and sensory quality of black pudding

The objective of this study was to investigate the interactive effects of varying fat and salt levels on the sensory and physicochemical properties of black pudding without using additional additives to produce a highly accepted product low in sodium and fat. Black pudding samples containing 0.6% sodium and 10% fat displayed a positive (P < 0.05) correlation to liking of flavor and overall acceptability which meets the sodium target level set by the Food Safety Authority of Ireland and shows additionally that a fat reduction in black pudding products is more than achievable.

Comparison of proximate composition and sensory attributes of Clariid catfish species of Clarias gariepinus, Heterobranchus bidorsalis, and their hybrids

The study determined the preference of Clariid catfish species of Clarias gariepinus, Heterobranchus bidorsalis, and their hybrids based on sensory – cognitive and qualitative parameters, and nutritional quality – proximate composition. In addition to the general cognitive features, the study employed the recent characteristic taste ‘umami’ in its assessment, and concluded that the catfish products are good sources of high protein, fat, and minerals that are indispensable in human diets; and also the parent catfish species possess better sensory qualities than hybrids, but all species need exogenous enhancement to their natural sensory components.

Safety of micronized palmitoylethanolamide (microPEA): lack of toxicity and genotoxic potential

Palmitoylethanolamide (PEA) of defined particle size (0.5–10 μm) was evaluated for mutagenicity in Salmonella typhimurium, for clastogenicity/aneuploidy in cultured human lymphocytes, and for acute and subchronic rodent toxicity in the rat, following standard OECD test protocols, in accordance with Good Laboratory Practice (GLP). No genotoxic effects were induced, and no adverse effects were found at the highest dose in the rodent studies.
