TL;DR: In this article, the preparation technology, biochemical and sensory characteristics of lactic acid fermented juice developed by using prickly pears (Opuntia sp.) as substrate are discussed.
Abstract: The demand of functional and probiotic foods are on the rise and there is always a quest to develop array of the products rather than the traditional milk derived products. The current study focuses on the preparation technology, biochemical and sensory characteristics of lactic acid fermented juice developed by using prickly pears (Opuntia sp.) as substrate. Prickly pears lacto-juice was prepared by fermenting the juice of prickly pears (diluted by appropriate factor) with a probiotic strain Lactobacillus fermentum ATCC 9338. The lacto-juice had the following compositions: total soluble solids, 5.9 °Brix; total sugar, 1.75 g/100 mL; reducing sugar, 0.20 g/100 mL; pH, 4.1; titratable acidity, 1.7 g tartaric acid/100 mL; lactic acid, 0.32 mg/100 mL; phenol, 0.41 μg/mL; ascorbic acid, 6 mg/100 mL, DPPH (2,2-diphenyl-1-picrylhydrazyl) scavenging activity, 105 μMTE (micro molar trolox equivalent)/mL. A total of nine proximate attributes loaded heavily on the dimension. Six analytical variables, i.e. titratable acidity (−), total soluble solids (+), total sugar (+), residual sugar (+), phenol (+) and DPPH (+) were loaded on PC1. Infrared spectroscopy revealed the presence of alkenes, organic acids, hydroxyl groups and nitro groups. GC-MS study indicated the disintegration of some risky organic compounds such as 4h-Pyran-4-one, 3, 5-dihydroxy-2-methyl; furfuryl alcohol; 2-propenenitrile, 2-(acetyloxy); 2, 2-diethyl-3-methyloxazolidine; acetaldehyde and furan present in the fresh fruit juice during the course of probiotic fermentation. The sensory panellists recommended the overall acceptability of the product.

TL;DR: In this paper, the authors used Lactobacillus plantarum (MTCC 1407) for 28 days to pickle the sweet potato roots by brining the cut and blanched roots in common salt (NaCl, 2-10%) solution.
Abstract: Lactic acid (LA) fermentation has many benefits. It is feasible in small scale, inexpensive, and does not require additives and confers organoleptic characteristics to the foodstuff according to the habits and requirement of the consumers. Sweet potato roots were pickled by lactic fermentation by brining the cut and blanched roots in common salt (NaCl, 2-10%) solution and subsequently inoculated With a strain of Lactobacillus plantarum (MTCC 1407) for 28 days. The treatment with 8-10% brine solution was found to be the most acceptable organoleptically. The final product with 8 and 10% brine solutions had a pH of 2.9-3.0, titratable acidity of 2.9-3. 7 g/kg LA of 2.6-3.2 g/kg and starch of 58-68 g/kg on fresh weight basis. Sensory evaluation rated the sweet potato lacto-pickle acceptable based on texture, taste, aroma, flavor and aftertaste. Principal component analyses reduced the six original analytical variables to two independent components (factors), which accounted for 92% of the total variations.

TL;DR: The results provided the genetic evidence to establish the diploidy of plants with 2n = 40 chromosomes and to support the hypothesis that plants are diploids, triploids and tetraploid, respectively, and that the basic chromosome number of D. alata is x-= 20.
Abstract: Dioscorea alata is a polyploid species with several ploidy levels and its basic chromosome number has been considered by most authors to be x = 10. Standard chromosome counting and flow cytometry analysis were used to determine the chromosome number of 110 D. alata accessions of the CIRAD germplasm collection. The results revealed that 76% of accessions have 2n = 40 chromosomes, 7% have 2n = 60 chromosomes and 17% have 2n = 80 chromosomes. Progenies were produced from 2n = 40 types of D. alata and the segregation patterns of six microsatellite markers in four different progenies were analysed. The Bayesian method was used to test for diploid versus tetraploid (allo- and autotetraploid) modes of inheritance. The results provided the genetic evidence to establish the diploidy of plants with 2n = 40 chromosomes and to support the hypothesis that plants with 2n = 40, 60 and 80 chromosomes are diploids, triploids and tetraploids, respectively, and that the basic chromosome number of D. alata is x = 20. The findings obtained in the present study are significant for effective breeding programs, genetic diversity analysis and elucidation of the phylogeny and the species origin of D. alata.

TL;DR: The present results suggested that the hypolipidaemic effect of dietary fibre involves a decrease in hepatic production of VLDL and further that it varies with the nature of the fibre.
Abstract: Different classes of fibres differ in their potential to lower lipid levels. In order to examine how chemically diverse fibres differ in their hypolipidaemic activity, mucilages of varying chemical composition isolated from three different sources were administered to experimental animals and the metabolism of lipids and lipoproteins was studied. The mucilages used were a galactomannan isolated from fenugreek (Trigonella foenum-graecum) seeds, a glucomannan from Dioscorea esculenta tubers and an arabinogalactan from Colocasia esculenta tubers. Rats were fed these mucilages at a dose of 4 mg/100 g body weight per d for 8 weeks and the changes in the levels of total cholesterol and triacylglycerols in serum, liver and aorta were analysed. All these mucilages decreased lipid levels both in serum and tissues. Among these mucilages, glucomannan showed the most hypolipidaemic effect followed by galactomannan and arabinogalactan. Further, hepatocytes were isolated from the livers of mucilage-fed rats and the synthesis and secretion of lipoproteins were studied using metabolic labelling. There was a decrease in the synthesis and secretion of apoB-containing lipoproteins, mainly VLDL, by hepatocytes isolated from mucilage-fed rats when compared to control (P < 0·05). This was further confirmed by pulse chase analysis. Among the different mucilages, mannose-rich glucomannan showed the most effect followed by galactomannan, and mannose-free arabinogalactan showed minimal effect. Comparison of relative viscosity and water-holding capacity showed that mannan-rich mucilages like galactomannan and glucomannan, which showed greater hypolipidaemic effect, had greater relative viscosity and water-holding capacity. The present results suggested that the hypolipidaemic effect of dietary fibre involves a decrease in hepatic production of VLDL and further that it varies with the nature of the fibre.
