The industrial application of pigments of biological origin has been gaining strength over time, which is mainly explained by the increased interest of the consumer for products with few synthetic additives. So, the search for biomolecules from natural origin has challenged food scientists and technologists to identify, develop efficient and less consuming strategies for extraction and characterization of biopigments. In this task, elucidation of molecular structure has become a fundamental requirement, since it is necessary to comply with compound regulatory submissions of industrial sectors such as food, pharmaceutical agrichemicals, and other new chemical entity registrations. Molecular elucidation consists of establishing the chemical structure of a molecule, which allows us to understand the interaction between the natural additive (colorant, flavor, antioxidant, etc) and its use (interaction with the rest of the mixture of compounds). Elucidation of molecular characteristics can be achieved through several techniques, the most common being infrared spectroscopy (IR), spectroscopy or ultraviolet-visible spectrophotometry (UV-VIS), nuclear-resonance spectroscopy (MAGNETIC MRI), and mass spectrometry. This review provides the details that aid for the molecular elucidation of pigments of fungal origin, for a viable and innocuous application of these biopigments by various industries.
随着时间的推移，生物源色素的工业应用越来越广泛，这主要是因为消费者对合成添加剂较少的产品兴趣增加。因此，从天然来源寻找生物分子对食品科学家和技术专家提出了挑战，要求他们确定、开发高效且消耗较少的生物色素提取和表征策略。在这项任务中，阐明分子结构已成为一项基本要求，因为有必要符合食品、制药、农用化学品等工业部门的化合物监管申报以及其他新化学实体注册要求。分子阐明包括确定分子的化学结构，这使我们能够了解天然添加剂（色素、香料、抗氧化剂等）与其用途之间的相互作用（与化合物混合物中其他成分的相互作用）。分子特征的阐明可以通过多种技术实现，最常见的是红外光谱（IR）、光谱或紫外-可见分光光度法（UV-VIS）、核磁共振光谱（MAGNETIC MRI）和质谱分析。本综述提供了有助于对真菌源色素进行分子阐明的详细信息，以便各行业能够切实且无害地应用这些生物色素。
