So far, the focus has been on the fact that it is called a nonthermal process and high pressure can affect bioavailability, but it is questionable whether the high pressure affects the ingredients themselves. By using an o/w-microemulsion (ME) as a model system, it was possible to investigate the influence of pressure, especially on lipophilic compounds (e.g., carotenoids and vitamin E), without the complexity of a food matrix. The ME consisted of Capryol® TM 90, Tween® 80 or 20, Transcutol® HP and distilled water. Lipophilic and hydrophilic compounds were introduced to the oil phase and to the aqueous phase, respectively. Storage experiments confirmed the applicability for β-carotene and α-tocopherol. HPP of MEs, performed for 10 min at room temperature (RT) and up to 600 MPa, resulted in pressure stability of β-carotene (exceptional at 400 MPa; −11%) and α-tocopherol. Multicomponent ME showed that both had a positive effect on the stability of chlorophyll a/b during HPP. An ME environment was used to facilitate co-oxidation of β-carotene via lipoxygenase (LOX) from an Edamame-based crude enzyme extract and lyophilized LOX-1 from soybeans during storage (RT and 4°C, dark conditions) and HPP treatment. A loss of β-carotene occurred after addition of linoleic acid, whereas effects of added α-tocopherol could be related to β-carotene protection. Overall, the introduced ME for studying HPP effects on lipophilic food ingredients showed promising results as versatile model system for future investigations regarding interactions of phytochemicals.</p>","PeriodicalId":100109,"journal":{"name":"Applied Research","volume":"3 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/appl.202400016","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140380489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To effectively remove water from natural gas, there is a need to design, compare and modify dehydration plants. This study investigated the performance difference between a conventional triethylene glycol (TEG)-based dehydration system with a cooler at the TEG inlet to the contactor, and a newly proposed TEG-based dehydration system with a heat exchanger replacing the cooler at the TEG inlet with the contactor. The advanced process simulation software Aspen HYSYS was used to design and compare two dehydration system configurations. The modified design configuration exhibited better performance in terms of energy conservation and water-removal capability. The material balance of molar flow, mass flow and volume flow of dry gas produced in the absorber/contactor column showed a higher volume of dry gas produced in the modified system configuration, indicating that it is a better design. The modified design configuration also produced dry gas within the recommended temperature range for underground storage and transmission. There was a significant difference in the percentage difference of 64% between the conventional and modified designs in terms of energy consumption, whereas the percentage differences of 0% and 0.6% showed nonsignificant and significant differences between the two plant design configurations.
