Evaluation of chemical composition and sensory profile in Jerusalem artichoke (Helianthus tuberosus L) tubers: the effect of clones and cooking conditions
Publication date: Available online 7 November 2017 Source:International Journal of Gastronomy and Food Science Author(s): Diana De Santis, Maria Teresa Frangipane Jerusalem artichoke (Helianthus tuberosus L.) (JA) produces ground artichokes, is resistant to most parasites, diseases and tough conditions such as frost and drought. It has many applications including biofuels or bio-chemicals that do not compete with food supply. Improving the genetic diversity would help meet food demand. Four clones of the JA were studied to determine sensory attributes, facilitate the characterization of each clone and promote a better ...

Inulin rich carbohydrates extraction from Jerusalem artichoke (Helianthus tuberosus L.) tubers and application of different drying methods
In this study the operational extraction variables to obtain higher yields of inulin from Jerusalem artichoke tubers (JAT), as well as the optimal conditions to obtain a stable and dispersible powdered product by either spray or freeze drying, were studied. With this purpose, the powder yield, moisture content, water activity and flowability or products obtained by different experimental conditions were analyzed. Inulin rich carbohydrates (IRC) extraction was performed from lyophilized and ground tubers employing distilled hot water as solvent. It was proved that the solid:solvent ratio (S:S) was the critical variable in t...

[Topinambour - nutritional and medical properties of the Jerusalem artichoke (Helianthus tuberoses L.)].
Abstract
Topinambour (Helianthus tuberosus L.), also known as the Jerusalem artichoke is a plant, which origins from North America. In XVII century it was brought to the Europe. For ages it was cultivated due to edible tuber and its healing properties.The aim of the article is to present medical properties and application of topinmbour in patient's diet. Many studies were performed on animals to specify medical properties of topinambour. Results show, that topinambour lowers plasma glucose, total cholesterol and triglyceride levels. It is believed that these effects are caused by high level of inulin prese...

Improving fructose utilization and butanol production by Clostridium acetobutylicum via extracellular redox potential regulation and intracellular metabolite analysis.
Abstract
Jerusalem artichoke (JA) can grow well in marginal lands with high biomass yield, and thus is a potential energy crop for biorefinery. The major biomass of JA is from tubers, which contain inulin that can be easily hydrolyzed into a mixture of fructose and glucose, but fructose utilization for producing butanol as an advanced biofuel is poor compared to glucose-based ABE fermentation by Clostridium acetobutylicum. In this article, the impact of extracellular redox potential (ORP) on the process was studied using a mixture of fructose and glucose to simulate the hydrolysate of JA tubers. When the e...

Efficient Conversion of Fructose-Based Biomass into Lipids with Trichosporon fermentans Under Phosphate-Limited Conditions.
In this study, an alternative strategy to promote lipid accumulation by the oleaginous yeast Trichosporon fermentans CICC 1368 was developed by limiting phosphorous supply, and this strategy was implemented with JA hydrolysate as substrate. We showed that lipid accumulation was directly correlated with the C/P ratio of the culture media for T. fermentans. The time course of cell growth and lipid production was analyzed in a media with an initial C/P ratio of 6342, and the cellular lipid content could reach up to 48.5% of dry biomass. Moreover, JA hydrolysates were used as substrate for microbial lipid accumulation, under h...

Non-enhanced phytoextraction of cadmium, zinc, and lead by high-yielding crops.
Abstract
Heavy metal soil contamination from mining and smelting has been reported in several regions around the world, and phytoextraction, using plants to accumulate risk elements in aboveground harvestable organs, is a useful method of substantially reducing this contamination. In our 3-year experiment, we tested the hypothesis that phytoextraction can be successful in local soil conditions without external fertilizer input. The phytoextraction efficiency of 15 high-yielding crop species was assessed in a field experiment performed at the Litavka River alluvium in the Příbram region of Czechia. This a...

Effect on nutritional, sensory, textural and microbiological properties of low ‐fat yoghurt supplemented with Jerusalem artichoke powder
The effect of supplementing two types of Jerusalem artichoke powder (JAP) with three different concentrations on the properties of low‐fat (LF) yoghurt was investigated. The results indicated that supplementation with JAPs improved the yoghurt's nutritional value, sensory score and microbial counts, while also ameliorating the syneresis, firmness and adhesiveness that was increased by the LF nature of the yoghurt. Although yoghurts with freeze‐dried (FD) JAP had higher viable counts of probiotics compared with oven‐dried (OD) JAP, the higher firmness and adhesiveness of yoghurts with the added FD JAP were undesirable...

Utilization of inulin-containing waste in industrial fermentations to produce biofuels and bio-based chemicals
AbstractInulins are polysaccharides that belong to an important class of carbohydrates known as fructans and are used by many plants as a means of storing energy. Inulins contain 20 to several thousand fructose units joined by β-2,1 glycosidic bonds, typically with a terminal glucose unit. Plants with high concentrations of inulin include: agave, asparagus, coffee, chicory, dahlia, dandelion, garlic, globe artichoke, Jerusalem artichoke, jicama, onion, wild yam, and yacón. To utilize inulin as its carbon and energy sour ce directly, a microorganism requires an extracellular inulinase to hydrolyze the glycosidic bonds to ...

Enhancement of 2,3-butanediol production from Jerusalem artichoke tuber extract by a recombinant Bacillus sp. strain BRC1 with increased inulinase activity.
Abstract
A Bacillus sp. strain named BRC1 is capable of producing 2,3-butanediol (2,3-BD) using hydrolysates of the Jerusalem artichoke tuber (JAT), a rich source of the fructose polymer inulin. To enhance 2,3-BD production, we undertook an extensive analysis of the Bacillus sp. BRC1 genome, identifying a putative gene (sacC) encoding a fructan hydrolysis enzyme and characterizing the activity of the resulting recombinant protein expressed in and purified from Escherichia coli. Introduction of the sacC gene into Bacillus sp. BRC1 using an expression vector increased enzymatic activity more than twofold. Co...
