The complete procedure for the production of inulin powder from Jerusalem artichoke tubers (JAT) was investigated. The procedure consists of isolation of inulin from JAT, elimination of color from the inulin extract and solidification. Washed tubers were first sliced, dried in a 60 °C oven for 10 h and then milled and sieved into a powder. Inulin was isolated from the JAT powder by hot water extraction using an accelerated solvent extractor (ASE). The effects of temperature and time for the extraction were investigated. The highest extraction efficiency was obtained at the extraction temperature of 80 °C for 20 min. The color of the extract was eliminated using ion exchange process with diethylaminoethyl cellulose as the sorbent. The inulin powder was subsequently obtained by freeze drying. Inulin content and inulin profiles were monitored to evaluate the efficiencies of the complete procedure. The inulin content was indirectly determined by spectrophotometry from free and total fructose measurements using potassium iodide. The inulin profile was monitored using high performance anion exchange chromatography equipped with integrated pulse amperometric detection (HPAEC-PAD). The proposed method provided the inulin production yield of 92.5%. The present procedure is fast, simple and effective for production of inulin powder from JAT. In addition, infrared spectra and some physico-chemical properties of the obtained inulin powder were determined and compared with the standard inulin.

Plant protein-stabilized Pickering nanoemulsions show potential as plant-based milk substitutes; however, their stability is challenged by mechanical stress during transportation and oxidative deterioration during storage. Herein, soybean isolate protein-curcumin composite nanoparticle (SPI-Cur-NPs)-stabilized Pickering nanoemulsions were converted into microcapsule powders via spray-drying with maltodextrin (MD), trehalose anhydrous (TA), and inulin (IN) as wall materials. Robust intermolecular hydrogen bonds and an amorphous structure were formed using composite wall materials, reducing microcapsule surface fissures while improving encapsulation rate (92.

Background: Recent studies show that the increase in breath hydrogen (BH) and symptoms after ingestion of inulin is reduced by co-administering psyllium.
Objectives: To determine if slowing delivery of inulin to the colon by administering it in divided doses would mimic the effect of psyllium. Primary endpoint was the BH area under the curve AUC.
Characterization of Physicochemical Properties, Bioactivities, and Sensory Attributes of Sea Buckthorn-Fava Bean Composite Instant Powder: Spray-Drying Versus Freeze-Drying Coupled with Carriers.

Foods and beverages with health benefits have become increasingly popular with consumers, and fruits and legumes are considered good sources of nutrients. In this study, sea buckthorn and fava bean were used as the main raw materials to prepare sea buckthorn-fava bean composite instant powder (S-FCP). Different drying methods (spray-drying (SD) and freeze-drying (FD)) combined with carriers (maltodextrin (MD) and inulin (INU)) were involved to investigate their effects on physicochemical properties, functional properties, and sensory attributes of instant powder.

Background: This study evaluated the effects of black tea drinks with inulin and dextrin (BTID) on postprandial plasma glucose (PG) in patients with type 2 diabetes mellitus (T2DM).
Methods: An acute, randomized, double-blind, placebo-controlled, crossover clinical trial was carried out on T2DM patients. The subjects were randomly assigned to groups consuming placebo black tea powder or BTID (identically packaged) followed by a mixed meal tolerance test (MMTT).
