Starch and protein analysis in buckwheat (Fagopyrum esculentum Moench) sprouts enriched with probiotic yeast
Probiotic‐rich bean sprouts alleviate oxidative stress and inflammation induced by a diet with an increased fat‐to‐carbohydrate energy ratio
SummaryThe rat's model evaluated the function of sprouted beans enriched with probiotic Lactiplantibacillus plantarum 299v in alleviating dyslipidaemia, inflammation and disturbed redox homeostasis caused by a high‐lard diet. Sprouted beans improved the total antioxidant capacity of serum and liver, regardless of whether the feeds had a higher content of low‐molecular antioxidants or were additionally enriched with probiotics. The reduction of inflammation (lowered level of C‐reactive protein) and restoration of triglycerides and total cholesterol to the levels recorded in the control group (AIN‐93M) were especially observed in the group supplemented with the control adzuki bean. Introducing sprouted legumes (both the control and probiotic‐rich) improved microbiota activity affected by a high‐lard diet. The highest, desirable reduction of urease (by 80%) and tryptophanase (by 78%) activity was found in the groups fed with probiotic‐rich adzuki and mung bean sprouts respectively. Sprouted beans improve the metabolism of individuals subjected to a diet with an increased fat‐to‐carbohydrate energy ratio, especially concerning oxidative stress injury and microbiota activity.
Effect of the Addition of Buckwheat Sprouts Modified with the Addition of Saccharomyces cerevisiae var. boulardii to an Atherogenic Diet on the Metabolism of Sterols, Stanols and Fatty Acids in Rats
The aim of the study was to evaluate the effect of the addition of Fagopyrum esculentum Moench buckwheat sprouts modified with the addition of Saccharomyces cerevisiae var. boulardii to an atherogenic diet on the metabolism of sterols and fatty acids in rats. It was noticed in the study that the group fed with modified sprouts (HFDPRS) had a greater amount of sterols by 75.2%, compared to the group fed on an atherogenic diet (HFD). The content of cholesterol in the liver and feces was lower in the HFDPRS group than the HFD group. In the serum of the HFDPRS group, a more significant amount of the following acids was observed: C18:2 (increase by 13.5%), C20:4 (increase by 15.1%), and C22:6 (increase by 13.1%), compared to the HFDCS group. Regarding the biochemical parameters, it was noted that the group fed the diet with the addition of probiotic-rich sprouts diet had lower non-HDL, LDL-C and CRP ratios compared to the group fed the high-fat diet. The obtained results indicate that adding modified buckwheat sprouts to the diet by adding the probiotic strain of the yeast may have a significant impact on the metabolism of the indicated components in the organism.
Adding Modified Buckwheat Sprouts to an Atherogenic Diet - the Effect on Selected Nutritional Parameters in Rats
Abstract The germinated seeds of many plants are a natural source of substances that can be used to supplement food and increase its functionality. The seeds’ metabolism may be modified during germination to produce specific health-promoting compounds. Fagopyrum esculentum Moench is a rich source of nutrients. Buckwheat seeds modified during germination may be helpful as an additive to new functional food products with anti-atherogenic properties. However, their effect and safety should be assessed in in vivo studies. The aim of the study was to evaluate the effect that adding modified buckwheat sprouts (Fagopyrum esculentum Moench) to an atherogenic (high-fat) diet has on the morphology and digestibility parameters of rats. Buckwheat seeds were modified by adding the probiotic strain of the yeast Saccharomyces cerevisiae var. boulardii. The study was carried out on 32 Wistar rats, and digestibility and blood counts were assessed during the experiment. There was no evidence of an adverse effect on the animals' weight gain and nutritional efficiency. However, the influence of diets with freeze-dried buckwheat sprouts on digestibility and morphological parameters was noticed. Fat digestibility registered a statistically significant decrease in the groups fed a high-fat diet with the addition of sprouts. The study shows a new direction in the use of buckwheat sprouts.
Analysis of Phenolic Compounds in Buckwheat (Fagopyrum esculentum Moench) Sprouts Modified with Probiotic Yeast
Buckwheat sprouts are a source of various nutrients, e.g., antioxidant flavonoids, which have a positive effect on human health. This study analyzed the content of phenolic compounds and assessed their impact on the antioxidant and anti-inflammatory properties and dietary fiber in modified buckwheat sprouts. For this purpose, the buckwheat seeds were modified by adding Saccharomyces cerevisiae var. boulardii. The modified buckwheat sprouts showed a higher content of total phenol compounds (1526 µg/g d.w.) than the control sprouts (951 µg/g d.w.) and seeds (672 µg/g d.w.). As a consequence, a higher antioxidant activity and anti-inflammatory effect were noted. Probiotic-rich sprouts also had the highest content of total dietary fiber and its soluble fraction. A correlation between phenolic compounds and the antioxidant and anti-inflammatory effects, as well as dietary fiber, was shown. The interaction between dietary fiber and phenolic compounds affects the bioaccessibility, bioavailability, and bioactivity of phenolic compounds in food. The introduction of probiotic yeast into the sprouts had a positive effect on increasing their nutritional value, as well as their antioxidant and anti-inflammatory activity. As a consequence, the nutraceutical potential of the raw material changed, opening a new direction for the use of buckwheat sprouts, e.g., in industry.
