Hazelnut shell is a lignocellulosic waste obtained from hazelnut processing. It is a potential source of pentose and hexose sugars (xylose, glucose) which can be used as a raw material for production of food enzymes, biofuel, and chemicals (acetic acid, furfural, methanol). An increasing interest in lignocellulosic wastes seems to stay consistent as these materials are low cost, renewable and abundant. The objective of the present study was to determine the effect of dilute acid (H2SO4) concentration, temperature and time on production of reducing sugars.The conventional one factor at a time approach showed that the highest concentration of reducing sugar was 16.74 g/L at a temperature of 130°C, an acid concentration of 3%, and a reaction time of 37.5 min, which also revealed a saccharification yield of 64.4%. Thus, this study showed that dilute acid hydrolysis is a promising pretreatment for hazelnut shells.

Bioconversion of Alkali Pretreated Hazelnut Shells to Fermentable Sugars for Generation of High Value Products
Uzuner, Sibel; Shivappa, Ratna Rani Sharma; Çekmecelioğlu, Deniz (2017-03-01)
Hazelnut shells are lignocellulosic by-products of hazelnut processing. As the shells are rich in cellulose and hemicellulose, they have high potential as a raw material for production of food enzymes, biofuel, and various chemicals (acetic acid, furfural and lignin degradation products) after bioprocessing. The objective of this study was to determine the effect of alkali pretreatment and enzymatic hydrolysis on production of fermentable sugars from hazelnut shells. The hazelnut shells were pretreated with...

In the biochemical conversion of lignocellulosic biomass to biofuels, the process of pretreatment is currently one of the most difficult and expensive operations. The use of ionic liquids (ILs) in biomass pretreatment has received considerable attention recently because of their effectiveness at decreasing biomass recalcitrance to subsequent enzymatic hydrolysis. In addition, ILs have the potential for decreasing the need for corrosive or toxic chemicals and associated waste streams that can be generated by...
CHARACTERIZATION OF ACTIVATED CARBON PRODUCED FROM ALMOND SHELL AND HAZELNUT SHELL
BALCI, S; Doğu, Timur; YUCEL, H (Wiley, 1994-08-01)
Ammonium chloride-impregnated and untreated almond shell and hazelnut shell samples were carbonized in a flow of nitrogen at relatively low temperatures. Pore structure characterization and sorption capacities of activated carbons prepared from shells of almond and hazelnut indicated that treatment with NH4Cl increased the total surface area and improved sorption characteristics. Chemical activation carried out at 350-degrees-C gave products with surface area values above 500 m2 g-1. On the other hand, the ...
Hydrolysis of Hazelnut Shells as a Carbon Source for Bioprocessing Applications and Fermentation
Uzuner, Sibel; Çekmecelioğlu, Deniz (Walter de Gruyter GmbH, 2014-12-01)
Hazelnut shells are generated in large amounts from hazelnut processing. Currently, it is used as fuel. However, reuse in bioprocessing can release remarkable content of sugars, which can be used for production of additives such as enzymes widely used in the food industry. Thus, the present study was undertaken to determine the effect of single and combined chemical and enzymatic hydrolysis on the production of fermentable sugars from hazelnut shells. Batch hydrolysis was carried out under various condition...
A preliminary investigation of caramelisation and isomerisation of allulose at medium temperatures and alkaline pHs: a comparison study with other monosaccharides
Ertuğrul, Ülkü; Taş, Ozan; Namlı, Serap; Öztop, Halil Mecit (2021-01-01)
Allulose, also known as rare sugar, is a very reactive monosaccharide in browning reactions. In this study, the caramelisation of allulose was investigated for the first time. To study caramelisation, sugar solutions (glucose, fructose and allulose) were prepared with distilled water and buffer solutions at pH 7, 10, 12 and were freeze-dried afterwards. To let caramelisation occur, samples were incubated at 55% relative humidity (RH) and 50 °C. Results showed that samples prepared with pH 10 and pH 12 buffe...
