Patent number: 11903400Abstract: The present invention relates to a process for fast and homogeneously heating a liquid product to a predetermined temperature by means of resistive heating. Sufficient and effective microbial inactivation is achieved upon applying an electrical field strength of between 0.1-5.0 kV/cm for a prolonged period of time, thus by selecting a relatively low electrical field strength and a pulse duration of at least 10 microseconds while the maximum temperature of the liquid product autonomously remains below 92° C. during the resistive heating. The present invention further relates to said process wherein the liquid product is pre-heated prior to subjecting the liquid product to the process. The present invention also relates to the liquid product obtainable by the process according to the invention.Type: GrantFiled: November 17, 2016Date of Patent: February 20, 2024Assignee: STICHTING WAGENINGEN RESEARCHInventors: Rian Adriana Hendrika Timmermans, Ricardo Ermirio De Moraes, Hendrikus Cornelis Mastwijk

Patent number: 11512330Abstract: It has been found that esterification of a hydroxy-fatty acid by a lipase can be coupled with oleate hydratase (OHase) generation of that hydroxy-FA from an unsaturated FA with a cis C9-C10 double bond, e.g. oleic acid, in a single aqueous buffered reaction medium at low temperature, e.g. 30° C. A simple one-pot enzymatic method to produce fatty acid estolides from one or more triglycerides, e.g. starting from a natural plant oil, is thereby enabled in which the same lipase catalyses both the initial hydrolysis of triglyceride and the final esterification step.Type: GrantFiled: January 25, 2021Date of Patent: November 29, 2022Assignees: Stichting Wageningen Research, Technische Universiteit DelftInventors: Carmen Gabriela Boeriu, Anamaria Todea, Isabella Wilhelmina Christina Everdina Arends, Ludwina Gerharda Otten

Patent number: 11284632Abstract: The invention relates to a method for obtaining a protein from a plant material, wherein the method comprises the steps of i) mechanically disrupting the plant cells to obtain a plant juice in the presence of a reducing agent, ii) treating the plant juice to cause aggregation of chloroplast membranes, iii) removing the aggregated chloroplast membranes by precipitation and/or microfiltration, iv) subjecting the plant juice to ultrafiltration, and v) subjecting the soluble plant protein concentrate to hydrophobic column adsorption to remove residual chlorophyll, phenolic compounds and off-odors in a single column passage. The present invention also pertains to an apparatus and system for plant protein isolation based on this method. The isolated proteins can be economically obtained in batch scale and in large scale. Further, the invention is directed to a protein obtained by the method of the invention, a food product comprising thereof, and a use thereof.Type: GrantFiled: December 20, 2013Date of Patent: March 29, 2022Assignee: STICHTING WAGENINGEN RESEARCHInventors: Govardus Adrianus Hubertus de Jong, Peter Geerdink, Paulus Josephus Theodorus Bussmann, Nienke Hylkema

Patent number: 10966381Abstract: A switch to haploid embryogenesis is controlled by the activity of histone deacetylases (HDACs). Blocking HDAC activity with HDAC inhibitors (HDACi), e.g. trichostatin A (TSA), in Brassica napus, B. rapa, B. oleracea, Arabidopsis thaliana and Capsicum annuum male gametophytes leads to a large increase in the proportion of cells that undergo embryogenic growth. In B. napus, treatment with one specific HDACi (SAHA) improves the conversion (i.e. germination) of these embryos into seedlings. Existing methods of culturing microspores of angiosperm plants following stress to produce haploid embryos, haploid plants and double haploid plants can be improved by adding HDACi to the culture medium. Advantageously, species hitherto recalcitrant to haploid embryogenesis via microspore culture are rendered useful when using HDACi. Haploid and double haploid plants are of industrial application in the plant breeding programmes.Type: GrantFiled: September 24, 2014Date of Patent: April 6, 2021Assignee: STICHTING WAGENINGEN RESEARCHInventors: Kimberly Boutilier, Gerrit Cornelis Angenent, Mercedes Soriano Castan, Li Hui
