A three-stage homogenate extraction was used as a new method for inulin extraction from Jerusalem artichoke tubers. Compared with the results from conventional hot water extraction, the three-stage homogenate extraction gave higher yields and caused less degradation of the inulin. The inulin crude extract was then clarified by a carbonate-precipitation method, during which three variables -the quicklime mass, the reaction temperature and the reaction time were optimized for the main liming process to give the best clarification effect. A PlackettBurman design, the path of steepest ascent method, a BoxBehnken design and response surface methodology (RSM) were employed in the experimental design. The optimal conditions for the main liming process were determined to be 12.0 g/L, 71.4°C and 8 min. The confirmatory tests proved that the best clarification efficiency (92.74%) was achieved at these conditions and this was approximately equal to the value predicted by the model.

“…Jerusalem artichoke has been accepted as a good raw material for ethanol production, human diet and medical applications (Kaur and Gupta, 2002;Szambelan et al, 2004;Takeuchi and Nagashima, 2011;Chen et al, 2013;Jin et al, 2013), because the tuber is rich in fructose and inuline (Baldini et al, 2004;Saengthongpinit and Saijaanantakul, 2005). More importantly, Jerusalem artichoke has been utilized to exploit abandoned saline land in coastal zone in China at present due to its high salinity tolerance (Zhao et al, 2006;Xue and Liu, 2008;Long et al, 2009).…”

a b s t r a c tIn order to explore the response of photosynthetic electron transport chain to heat stress, chlorophyll a fluorescence and modulated 820 nm reflection transients were examined in the leaves of Jerusalem artichoke (Helianthus tuberosus L.). J step was elevated at 43• C, suggesting that electron transport beyond primary quinone electron acceptor of photosystem II (Q A ) was inhibited. I step was elevated at 45• C due to the lowered plastoquinol re-oxidation rate. Significant decrease in the Q A reducing reaction centers per photosystem II (PSII) antenna chlorophyll and marked increase in relative variable fluorescence intensity at 300 s also occurred at 45• C, indicating that the electron transport chain from PSII donor side to Q A was injured. Overall, the fragment between Q A and plastoquinol is the most susceptible to heat in the electron transport chain before photosystem I (PSI). The maximal photochemical capacity of PSI was not affected by heat stress even at 48• C, and the interaction between PSII and PSI become unbalanced, when temperature rose to 45• C. At 45 • C, prolonged PSI oxidation occurred in the expanding leaves because of the inhibited electron donation from PSII, however, PSI oxidation amplitude decreased in the expanded leaves. We infer that electron transport chain of PSI acceptor side is more sensitive to heat stress than the chain before PSI in the expanded leaves. Therefore, electrons in PSI reaction center could not be efficiently drained to the downstream at high temperature, and then PSI oxidation was blocked.

“…In the recent years, Jerusalem artichoke has been accepted as a good source of fructose and inuline (Saengthongpinit and Saijaanantakul 2005) that can be used for many purposes like ethanol production, human diet and medical applications (Kaur and Gupta 2002;Szambelan et al 2004;Takeuchi and Nagashima 2011). It has been reported that Jerusalem artichoke possesses high drought tolerance and can be cultivated at a relatively low cost without irrigation (Monti et al 2005).…”

Gas exchange, chlorophyll a fluorescence and modulated 820 nm reflection were investigated to explore the development of photosynthesis in Jerusalem artichoke (Helianthus tuberosus L.) leaves from initiation to full expansion. During leaf expansion, photosynthetic rate (Pn) increased and reached the maximal level when leaves were fully expanded. The same change pattern was also found in the stomatal conductance and chlorophyll content. Lower Pn could not be ascribed to the higher stomatal resistance in developing leaves, as intercellular CO 2 concentration was not significantly lower in these leaves. Lower Pn partly resulted from the lower actual photochemical efficiency of PSII in developing leaves, as more excited energy was dissipated through non-photochemical quenching. The development of primary photochemical reaction and electron transport in the donor side of PSII was completed in the initiating leaves. However, the development of electron transport in the acceptor side of PSII was not accomplished until leaves were fully expanded, indicated by the change in probability that an electron moves further than primary quinone (wo). PSI activity changed in parallel with wo suggesting that PSI cooperated well with PSII during leaf expansion. It should be stressed that the development of carbon fixation process was later than primary photochemical reaction but earlier than photosynthetic electron transport during leaf expansion. The later development of photosynthetic electron transport may reduce the production of reactive oxygen species from Mehler reaction, particularly under low carbon fixation.
