The Meat of the Matter: Plant-Based Meat Analogue versus Traditional Meat Product Nutritional Quality

引用

Food Science and Human Wellness 2024年

作者： arshia Shireen Amanda J Wright Department of Human Health and Nutritional Sciences， University of Guelph Guelph， Ontario， Canada bDepartment of Human Health and Nutritional Sciences， University of Guelph Guelph， Ontario， Canada

Plant-based meat analogues (PBMA) are formulated to mimic the sensory characteristics of traditional meat products (TMP) using vegetarian ingredients and are increasingly popular with the trend towards plant-based diets， even among meat-eating consumers. This narrative review compared the nutritional quality of PBMA and TMP to broaden the discussion on the suitability of simulated meat products to substitute TMP， while exploring other attributes for their comparison. The complexity of PBMA and TMP means they are not entirely interchangeable. Importantly， PBMA health effects extend beyond their basic nutrient content and quality. Postprandial metabolism and satiety， for example， can be affected by product formulation， ingredient interactions， and thermomechanical processing involved in producing organoleptically acceptable PBMA. There are specific opportunities for low-sodium PBMA products to contribute to a healthy shift toward plant-based diets. In conclusion， PBMA cannot be assumed to be healthier than TMP. They should be designed with comprehensive consideration of composition and processing to ensure they support consumers who are adopting plant-based diets in realizing the theoretical health benefits.

Aggregation-induced emission meets magnetic bistability: Synergy between spin crossover and fluorescence in iron(Ⅱ) complexes

引用

Chinese Chemical Letters 2023年第4期34卷 608-613页

作者： Yao Li Mohammad Khurram Javed Shu-Qi Wu arshia Sulaiman Ying-Ying Wu Zhao-Yang Li Osamu Sato Xian-He Bu School of Materials Science and Engineering Nankai UniversityTianjin 300350China Institute for Materials Chemistry and Engineering Kyushu UniversityFukuoka 819-0395Japan

Luminescent spin crossover(SCO) materials have attracted significant interest owing to their potential applications in magneto-optical switches. However, the majority of previously reported FeII-based SCO complexes are adversely affected by fluorescence quenching in the solid-state. Here, we have constructed the first mononuclear FeIIcomplex decorated with an aggregation-induced emission(AIE) luminophore(i.e., tetraphenylethylene) that exhibits synergistic SCO and fluorescence behavior. Intriguingly, we obtained two types of crystals in different solvent systems, both displaying distinct magnetic bistability and fluorescence properties. The fluorescence intensity was observed to track the magnetic susceptibility, which confirmed that SCO and solid-state fluorescence operate synergistically. We introduce a novel approach for the construction of luminescent SCO compounds using an AIEgen as a luminophore, which leads to fluorescence emission in the solid-state, thus allowing us to study the synergy between SCO and fluorescence.
