在这项研究中,独特的化学指纹,有助于各种蛋白质材料的风味特征,比如昆虫,植物性蛋白质,牲畜,被调查了。在食用昆虫中(黄粉虫和短生Protaetia),醛和环状挥发性化合物是主要的挥发性成分,具有独特的风味特征,如奶酪,锋利,绿色,花卉,和甜蜜。相比之下,植物性蛋白质材料中吡嗪和呋喃含量相对较高,如有纹理的蔬菜和豌豆蛋白。它们包括独特的风味特性,以甜味为特征,脂肪,长满草,奶油,和烤。在牲畜蛋白质材料中检测到的主要挥发性化学基团,比如猪肉和牛肉,是酮。猪肉样品显示出特定的味道,比如酒鬼,绿色,和果味,虽然牛肉呈现出独特的味道,包括奶油,果味,和酒鬼。根据结果,这项研究提供了对不同蛋白质材料的风味方面的理解。
In this study, the distinctive chemical fingerprints that contribute to the flavor characteristics of various protein materials, such as insects, plant-based protein, and livestock, were investigated. In edible-insects (Tenebrio molitor and Protaetia brevitarsis), aldehydes and cyclic volatile compounds were the predominant volatile components and had distinct flavor characteristics such as cheesy, sharp, green, floral, and sweet. In contrast, the relatively high levels of pyrazines and furans in plant-based protein materials, such as textured vegetable and pea protein. They included unique flavor properties characterized by sweet, fatty, grassy, creamy, and roasted. The primary volatile chemical group detected in livestock protein materials, such as a pork and a beef, was ketones. The pork sample showed specific flavors, such as alcoholic, green, and fruity, while a beef presented distinctive flavor, including creamy, fruity, and alcoholic. Based on the results, this research provided the understanding of the flavor aspects of diverse protein materials.
