Recovery of lactose from simulated delactosed whey permeate by a low-temperature crystallization process

Autor: Ruben Halfwerk, Doekle Yntema, Jaap Van Spronsen, Albert Van der Padt

Publikováno v: Journal of Dairy Science, Vol 106, Iss 9, Pp 5958-5969 (2023)

ABSTRACT: Delactosed whey permeate is the mother liquor/by-product of lactose manufacture, but it still contains around 20 wt% lactose. The high mineral content, stickiness, and hygroscopic behavior prevent further recovery of lactose in the manufact

Eutectic freeze crystallization is explored as an alternative to the state-of-the-art evaporation process for the recovery of lactose from whey permeate. At the so-called eutectic freezing point, both water (the solvent) and lactose (the solute) crys

Crystallization kinetics of lactose at sub-zero temperatures are modelled in this paper using a population balance model. There are two competing effects on the crystallization kinetics at low temperatures. On the one hand, mass transport and the rat

Deep eutectic solvents (DESs) based on terpenes are identified and characterized. 507 combinations of solid components are tested, which results in the identification of 17 new hydrophobic DESs. Four criteria are introduced to assess the sustainabili

A sub-zero crystallization process for the recovery of lactose

Publikováno v: Journal of Food Engineering, 308
Journal of Food Engineering 308 (2021)

In industry, lactose is generally produced by concentrating whey permeate by evaporation followed by a slow cooling process where lactose is crystallized. Here, an alternative method is presented whereby the concentration and crystallization steps ar

Oil-in-water emulsions based on hydrophobic eutectic systems

We demonstrate that oil-in-water emulsions can be prepared from hydrophobic eutectic systems (ES). Light microscopy and dynamic light scattering show that droplets are formed and zeta potential measurements indicate sufficient stability against coale

The Effect of Acids on Alkaloid Yield in Pressurized Water Extraction of Narcissus Pseudonarcissus

Autor: Orchidea Rachmaniah, Jaap van Spronsen, Robert Verpoorte, Geert Jan Witkamp

Publikováno v: Journal of Engineering and Technological Sciences, Vol 53, Iss 6 (2021)

Pressurized water (PW) extraction of galanthamine from Narcissus pseudonarcissus bulbs was performed. The obtained yield was compared with the yield from conventional acidified water extraction and methanolic Soxhlet extraction. Both PW and conventio

Publikováno v: Chemical Engineering Science, 165, 74-80. Elsevier

The use of industrial waste streams as a source of biomass is beneficial, not only to reduce environmental problems, but also to save valuable resources. Waste streams containing volatile fatty acids (VFAs) are one such example. However, separation f

Ionic Liquids and Deep Eutectic Solvents in Natural Products Research: Mixtures of Solids as Extraction Solvents

Autor: Geert-Jan Witkamp, Yuntao Dai, Robert Verpoorte, Jaap van Spronsen, Young Hae Choi

Publikováno v: Journal of Natural Products. 76:2162-2173

Mixtures of solid chemicals may become liquid under certain conditions. These liquids are characterized by the formation of strong ionic (ionic liquids) or hydrogen bonds (deep eutectic solvents). Due to their extremely low vapor pressure, they are n
