Bark from Nordic tree species – a sustainable source for amphiphilic polymers and surfactants

Autor: Isabella Kwan, Tianxiao Huang, Monica Ek, Rauni Seppänen, Peter Skagerlind

Publikováno v: Nordic Pulp & Paper Research Journal. 37:566-575

Many of the amphiphilic molecules, or surfactants, are produced from fossil-based raw materials. With the increasing awareness of the climate situation, focus has shifted toward more environmentally friendly solutions to replace fossil-based products

Durability of the Sizing Degree of AKD and ASA Sized Papers Investigated by Contact Angle Measurements and ToF-SIMS

Autor: Rauni Seppänen

Publikováno v: Journal of Dispersion Science and Technology. 30:937-948

The influence of storage conditions on the sizing degree of AKD and ASA sized pilot papers was evaluated. A number of pilot papers sized with AKD or ASA were prepared from ECF bleached pulp fiber ...

Sodium caseinates with an altered isoelectric point as emulsifiers in oil/water systems

Autor: Pirkko Forssell, Harry Boer, Rauni Seppänen, Hairan Ma, Riitta Partanen, Johanna Buchert

Publikováno v: Ma, H, Forssell, P, Partanen, R, Seppänen, R, Buchert, J & Boer, H 2009, ' Sodium caseinates with an altered isoelectric point as emulsifiers in oil/water systems ', Journal of Agricultural and Food Chemistry, vol. 57, no. 9, pp. 3800-3807 . https://doi.org/10.1021/jf803104s

Sodium caseinate was chemically modified in order to alter its isoelectric point (pI). Negatively charged carboxylic groups were introduced to lower the pI, and positively charged amino groups to achieve the opposite. Different chemical amino acid mo

Effect of relative humidity on oxidation of flaxseed oil in spray dried whey protein emulsions

Autor: Pirkko Forssell, Johanna Buchert, Janne Raula, Rauni Seppänen, Riitta Partanen, Esko I. Kauppinen

Publikováno v: Partanen, R, Raula, J, Seppänen, R, Buchert, J, Kauppinen, E I & Forssell, P 2008, ' Effect of relative humidity on oxidation of flaxseed oil in spray dried whey protein emulsions ', Journal of Agricultural and Food Chemistry, vol. 56, no. 14, pp. 5717-5722 . https://doi.org/10.1021/jf8005849

Flaxseed oil was emulsified in whey protein isolate (WPI) and spray-dried. Powder characteristics and oxidative stability of oil at relative humidities (RH) from RH approximately 0% to RH 91% at 37 degrees C were analyzed. Oil droplets retained their

Mechanism of internal sizing by alkyl ketene dimers (AKD): The role of the spreading monolayer precursor and autophobicity

Autor: Fredrik Tiberg, M. P. Valignat, Rauni Seppänen

Publikováno v: Nordic Pulp & Paper Research Journal. 15:452-458

Alkyl ketene dimers (AKD) only partially wet cellulose and silica surfaces. Further spreading of AKD molecules is shown to occur by surface diffusion in the form of an autophobic monolayer precur ...

Heteroflocculation of kaolin pre-treated with oppositely charged polyelectrolytes

Autor: Göran Ström, Rauni Seppänen, J. Elftonson

Publikováno v: Colloids and Surfaces A: Physicochemical and Engineering Aspects. 164:131-141

Heteroflocculation studies of kaolin particles have been carried out by mixing two kaolin suspensions; one stabilised by a cationic polymer and the other stabilised by a highly charged and low molecular weight anionic polymer. Molar mass and charge d
