Comparison of Dilute Acid and Alkali Catalysed Liquid Hot Water Pretreatment of Hazelnut Shells for Enzymatic Hydrolysis
(Eta-Florence Renewable Energies, 2015)
The efficiency of alkali and acid pretreatment of hazelnut shells for increasing enzymatic saccharification of cellulose has been evaluated. Hazelnut shells were pretreated with 1% of sulphuric acid, and 2.25 % sodium ...
Optimization of Hydrothermal Pretreatment Parameters for Glucose and Xylose Recovery From Poppy Stalks
(Eta-Florence Renewable Energies, 2015)
Response surface methodology (RSM) was employed to optimize hydrothermal pretreatment conditions for glucose and xylose recovery from poppy stalk, with respect to temperature (120-200oC), solid to liquid ratio (0.05-0.20) ...
Investigation of the effect of low temperature low time alkali pretreatment on hazelnut shells composition and enzymatic hydrolysis
(Gazi University, Fac Engineering Architecture, 2017)
In this study, effect of low temperature-short time alkali pretreatment of hazelnut shells on glucose recovery after enzymatic hydrolysis was investigated. NaOH pretreatment was found to give the highest glucose recovery. ...
Ethanol production from hazelnut shells through enzymatic saccharification and fermentation by low-temperature alkali pretreatment
(Elsevier Sci LTD, 2017)
Low-temperature sodium hydroxide (NaOH) pretreatment, enzymatic saccharification and ethanol fermentation were evaluated for hazelnut shell cellulose to fermentable sugars and ethanol. Maximum glucose recovery (48.33 g/100 ...
Antioxidant activity and phenolic composition of sumac (Rhus coriaria L.) extracts
(Elsevier Sci LTD, 2007)
Antioxidant activity and phenolic compounds of sumac extracts were investigated. Sumac was extracted in methanol and subjected to solvent-solvent partitioning to yield two fractions as ethyl acetate and aqueous. Methanol ...
Extraction of poppy seed oil using supercritical CO2
(Inst Food Technologists, 2003)
Extraction of poppy seed oil with supercritical carbon dioxide (SC-CO2) was performed and the effect of extraction conditions on oil solubility and yield as well as oil composition was evaluated. Within the temperature (50 ...
Optimization of Alkaline Pretreatment for Enzymatic Saccharification of Poppy Stalks
(North Carolina State University Dept Wood & Paper Sci, 2014)
Response surface methodology (RSM) was employed to optimize dilute alkaline pretreatment conditions for the maximum glucose yield of poppy stalk, with respect to NaOH concentration (1.0 to 3.5%, w/v), pretreatment temperature ...
Study of polyphenol content in the seeds of red grape (Vitis vinifera L.) varieties cultivated in Turkey and their antiradical activity
(Elsevier Sci LTD, 2008)
The polyphenolic content and antioxidant capacity in the seeds of 11 red grape varieties (five international and six native) widely cultivated in Turkey were investigated. Total phenolic, total flavanol and total polymeric ...
Antioxidants from laurel (Laurus nobilis L.) berries: influence of extraction procedure on yield and antioxidant activity of extracts
(Akademiai Kiado, 2007)
The antioxidant activities of laurel (Laurus nobilis L.) berries extracts were evaluated using a DPPH assay, a beta-carotene/linoleic acid assay and the Rancimat method. Pericarp and kernel of berries were extracted by ...
Effect of Temperature and Time on the Steam Pretreatment of Hazelnut Shells for the Enzymatic Saccharification
(Aidic Servizi Srl, 2014)
Saturated steam pretreatment of hazelnut shells was studied for fermentable sugars after enzymatic hydrolysis. The elevation of temperature (from 160 to 200 degrees C) and time (0-30 min) of steam pretreatment were ...
