“…In C. acanthoides ethanol extracts nystose dominated, followed by 1-kestose, and sugars sucrose, glucose and fructose. The FOSs (1-kestose and nystose) and glucose, fructose and sucrose profile of the O. tauricum extracts was similar to artichoke bract waste extract reported by Machado et al (2015) and C. thoermeri (Petkova et al, 2015а). The 1-kestose content in O. tauricum reached values comparable with other source of prebiotics as dandelion root (Petkova et al, 2015b) and Jerusalem artichoke tubers .…”

“…Ultrasonic power controlled by processor amplitude was the most important factor which increased both CE and CPS. Increase in CE came from required higher energy for applying boosted power increase by raising amplitude (Machado et al 2015). Sonication intensity was found an important factor on both b-glucan yield and molecular weight.…”

The aim of this study is to evaluate optimum process conditions for water soluble polysaccharides (WSP) of plant waste materials such as hazelnut skin by using response surface methodologies (RSM). Polysaccharides from hazelnut skin were extracted by means of probe type sonication system using distilled water as a solvent with several sonication time, temperature and amplitude. Response surface models were applied by both Box–Behnken Design (BBD) and Central‐Composite Design (CCD) for determining optimal condition which satisfies both maximizing polysaccharide yield and minimizing applied energy for sonication. Results showed that both BBD and CCD models represented the system with high regression coefficient (R2 > 0.95) and optimum conditions are 16.15 min, 45C, 50.29% amplitude with 0.733 desirability, 15.97 min, 45C, 47.27% amplitude with 0.712 desirability, respectively, for designs. Results of given conditions are 1.74% yield and 78.75 kJ consumption for BBD and 1.64% yield and 71.68 kJ for CCD. These results were validated by comparing experimental results at 15 min, 45C, 50% amplitude. As a consequence, it was observed that selected statistical models represent the system with a high accuracy and associating scores of each optimal condition is close enough to experimental results. Practical Applications Hazelnut skin is accepted as a waste material and there is no known application area in food industry. Although this waste can be utilized as bioactive polysaccharide source, extraction procedure requires enzymatic and chemical treatments. Sonication can be applied to extract water soluble polysaccharide from hazelnut skin and this method can be applied practically for further studies. Because during polysaccharide extraction, sonication improves uniform heat distribution and enhances mass transfer while decreasing activation energy due to the increase in particle velocity, intense mixing, cell disruption and partial hydrolysis. These effects make sonication profitable tool to obtain bioactive polysaccharides from plant waste materials. RSM is an easy way to organize experiments and optimize complex system such as extraction. On the other hand BBD design is easier and more applicable then CCD especially when the process has some concerns such as difficulties to adjust required level of parameters for CCD.

“…This material consists mainly of the leaves and stems, removed at the end of collection during natural drying, and external bracts discarded during industrial processing . Some studies have demonstrated that artichoke wastes are a good source of phenolic compounds and inulin , highlighting their high added value as food by‐products in the recovery of functional and health‐promoting ingredients. Today, food by‐products of plant origin are considered a cheap and suitable source of functional compounds, which may be recovered and used as biologically active components in functional foods and/or dietary supplements or as natural food ingredients to replace synthetic additives .…”

Pressurized hot water extraction of bioactive compounds from artichoke by‐products

Artichoke by-products are a suitable source of health-promoting ingredients for the production of dietary supplements and food additives. A pressurized hot water extraction (PHWE) was developed to recover caffeoylquinic acids (CQAs) and flavone glycosides (FLs) from agro-industrial artichoke by-products. The main factors influencing PHWE efficiency and CQA isomerization (temperature, numbers of cycles, modifier, and extraction time) were carefully studied and optimized by response surface design. The proposed PHWE procedure provides an exhaustive extraction of CQAs and FLs (recoveries: 93-105% and 90-105%) from artichoke external bracts and leaves of different cultivars (p > 0.05), without significant formation of artefacts generated by high temperatures. PHWE extracts showed CQA and FL levels (14-37 mg/g and 3-19 mg/g, respectively) comparable to commercial products and marked antioxidative effects (EC 11-83 μg/mL) by cellular antioxidant activity assay in human hepatocarcinoma HepG2 cells. These results proved that PHWE is an excellent green technique to recover bioactive compounds from artichoke agro-industrial residues.
