In the present study the effect of co-encapsulation of probiotic organism Lactobacillus helveticus 194 with prebiotics (FOS) in kulfi was studied on the sensory attributes during frozen storage. Co-encapsulation of probiotics (1 × 107cfu/g) with prebiotic (3% FOS) was done with extrusion method using 2% alginate. Three lots of kulfi mixes each of 2.5 kgs were prepared i.e. kulfi prepared without supplementing any probiotics was kept as a control, treatment I-kulfi suuplemented with encapsulated Lactobacillus helveticus 194 (@ 8.75 log10 cfu/g), treatment II-kulfi supplemented with non encapsulated Lactobacillus helveticus 194 (@ 8.66 log10 cfu/g). Sensory evaluation of kulfi samples was done using 9 point hedonic scale. No significant difference was observed in terms of colour and appearance, flavor and taste, body and texture and overall acceptability of kulfi samples supplemented either with co-encapsulated or non encapsulated probiotic bacteria but higher sensory scores have been observed in probiotic kulfi samples supplemented with co-encapsulated probiotics than non encapsulated probiotics. This study has shown that co-encapsulation of probiotic bacteria has no significant effect on sensory properties of kulfi further the addition of co-encapsulated probiotic organisms increased the sensory profile of the product than non encapsulated ones....
Soymilk is used as a food supplement and it contains ingredients like isoflavonoids, vitamins, proteins and minerals which provide health benefits. The major obstacle in the studies with soymilk is its instability due to the sensitivity of its ingredients to conditions like light, moisture and temperature. The present work was an attempt to enhance the stability of soymilk by using different drying processes and improving its antioxidant potential by the means of fermentation and combination with a cereal (finger millet). Four types of soymilk powder were taken i.e. non fermented freeze dried soymilk powder (NFFD-1), non fermented spray dried soymilk powder (NFSD-1), fermented soymilk powder by L. plantarum NCIM 2083 (FFD-1) and 1:1 combination ratio of soymilk and finger millet powder (NFFD-2). NFFD-1 and NFSD-1, FFD-1 and NFFD-2 were studied for total phenolic contests, flavonoid content, confirmation of presence of isoflavnoids (diadezein, genistein) by HPLC. In vitro antioxidant models like DPPH, ABTS and nitric oxide scavenging activities followed by iron chelation and lipid peroxidation assays were used to study the antioxidant activity using Freeze dried finger millet (NFFD-2) and combination (1:1) of soymilk and finger millet (NFFD-3). In all the models studied, FFD-1 and NFFD-3 showed better activities. Hence, finger millet used as a supplement with soymilk showed better antioxidant activity. Genistein concentration was found to be higher in FFD-1 than NFFD-1 and NFSD-1....
Fruit pods contain various beneficial compounds that have biological activities\r\nand can be used as a source of pharmaceutical and nutraceutical products. Although pods\r\nor pericarps are usually discarded when consuming the edible parts of fruits, they contain\r\nsome compounds that exhibit biological activities after extraction. Most fruit pods included\r\nin this review contain polyphenolic components that can promote antioxidant effects on\r\nhuman health. Additionally, anti-inflammatory, antibacterial, antifungal and chemopreventive\r\neffects are associated with these fruit pod extracts. Besides polyphenolics, other compounds\r\nsuch as xanthones, carotenoids and saponins also exhibit health effects and can be potential\r\nsources of nutraceutical and pharmaceutical components. In this review, information on\r\nfruit pods or pericarp of Garcinia mangostana, Ceratonia siliqua, Moringa oleifera,\r\nAcacia nilotica, Sapindus rarak and Prosopis cineraria is presented and discussed with\r\nregard to their biological activity of the major compounds existing in them. The fruit pods\r\nof other ethno- botanical plants have also been reviewed. It can be concluded that although\r\nfruit pods are considered as being of no practical use and are often being thrown away,\r\nthey nevertheless contain compounds that might be useful sources of nutraceutical and\r\nother pharmaceutical components....
Aging is a complex and inevitable biological process that is associated with numerous chronically debilitating health effects.\r\nDevelopment of effective interventions for promoting healthy aging is an active but challenging area of research. Mechanistic\r\nstudies in various model organisms, noticeably two invertebrates, Caenorhabditis elegans and Drosophila melanogaster, have\r\nidentified many genes and pathways as well as dietary interventions that modulate lifespan and healthspan. These studies have\r\nshed light on some of the mechanisms involved in aging processes and provide valuable guidance for developing efficacious aging\r\ninterventions. Nutraceuticals made from various plants contain a significant amount of phytochemicals with diverse biological\r\nactivities. Phytochemicals can modulate many signaling pathways that exert numerous health benefits, such as reducing cancer\r\nincidence and inflammation, and promoting healthy aging. In this paper, we outline the current progress in aging intervention\r\nstudies using nutraceuticals from an evolutionary perspective in invertebrate models....
Background: Although statins (STs) are drugs of first choice in hypercholesterolemic patients, especially in those at\r\nhigh cardiovascular risk, some of them are intolerant to STs or refuse treatment with these drugs. In view of this, we\r\nhave evaluated the lipid-lowering effect of a nutraceutical pill containing berberine (BBR) and of ezetimibe, as\r\nalternative treatments, in monotherapy or in combination, in 228 subjects with primary hypercholesterolemia (HCH),\r\nwith history of STs intolerance or refusing STs treatment. In addition, since PCSK9 was found up-regulated by STs\r\ndampening their effect through an LDL receptors (LDLRs) degradation, and BBR suppressed PCSK9 expression in\r\ncellular studies, we supplemented the stable lipid-lowering therapy of 30 genotype-confirmed Familial\r\nHypercholesterolemia heterozygotes (HeFH) with BBR, searching for a further plasma cholesterol reduction. Plasma\r\nlipid pattern was evaluated at baseline and during treatments.\r\nResults: In HCH subjects the nutraceutical pill resulted more effective than EZE in lowering LDL cholesterol\r\n(-31.7% vs -25.4%, P < 0.001) and better tolerated. On treatment, LDL-C level below 3.36 mmol/L (=130 mg/dl) was\r\nobserved in 28.9% of subjects treated with the nutraceutical pill and 11.8% of those treated with EZE (P <0.007). In\r\nthe group treated with EZE the subjects carrying the G allele of the g.1679 C > G silent polymorphism of NPC1L1\r\ngene showed a higher response to EZE than homozygous for the common allele (GG CG: LDL-C -29.4�±5.0%, CC\r\n-23.6�±6.5%, P <0.001). Combined treatment with these drugs was as effective as STs in moderate doses (LDL\r\ncholesterol -37%, triglycerides -23%). In HeFH patients the addition of BBR resulted in LDL cholesterol reductions\r\ninversely related to those induced by the stable therapy (r = -0.617, P <0.0001), with mean 10.5% further decrease.\r\nConclusions: The alternative treatments tested in our HCH subjects were rather effective and safe. The findings in\r\nHeFH patients suggest that BBR might act in vivo increasing expression and stability of LDLRs and/or suppressing\r\nPCSK9 expression....
The use of natural honey (NH) as a nutraceutical agent is associated with nutritional benefits and therapeutic\r\npromises. NH is widely accepted as food and medicine by all generations, traditions and civilizations, both ancient\r\nand modern. The nutritional profiles, including its use in infant and children feeding reported in different literatures\r\nas well as health indices and biomarkers observed by various researchers are illustrated in this manuscript. The\r\nreview documents folk medicine, experimentation with animal models, and orthodox medical practices shown by\r\nclinical trials. This covers virtually all human organs and body systems extensively studied by different workers.\r\nThe sources and adverse effects of NH contamination, as well as the preventive methods are identified. This could\r\npromote the availability of residue free honey and a wholesome natural product for domestic consumption and\r\ninternational market. This could also help to prevent health problems associated with NH poisoning. In addition,\r\napicultural practices and the economic importance of honey are well documented. This report also includes\r\ninformation about a relatively unknown and uncommon South American stingless bee species. We concluded this\r\nreview by identifying important roles for Ethno-entomologists, other Scientists and Apiculturists in the development\r\nof stingless bees to boost honey production, consumption and economic earnings...
The present study was done to evaluate the effect of co-encapsulation of probiotic organism namely, Lactobacillus helveticus 194 along with commercial prebiotic sugars (FOS) on changes in pH and titratable acidity and meltdown values of kulfi, analyzed during 90 days of frozen storage (-20°C) at fifteen days interval. Co-encapsulation of probiotics @ 8.75 log10 cfu/g together with 3% prebiotic sugars (FOS) was made by extrusion method using 2% sodium alginate solution. Three categories of kulfi mixes of 2.5 Kg each were formulated as per standard method. Control kulfi was made without supplementing probiotics in the kulfi mix, treatment I was supplemented with encapsulated Lactobacillus helveticus 194 (@ 8.75 log10 cfu/g), treatment II was supplemented with non encapsulated Lactobacillus helveticus 194 (@ 8.66 log10 cfu/g. The results showed that the mean pH values of probiotic kulfi decreased from initial day to 90 days, whereas the mean titratable acidity values and mean melt down rate values increased from initial day to 90 days of frozen storage....
