Following the debate on food processing, resulting in a negative definition of ultra-processed products, the improvement of the food system could be pursued through the co-creation of new food solutions aimed at enhancing human health and increasing safety and sustainability, in particular by using neglected foodstuff, crops or by-products, and applying mild processing technologies. The proper management of mild/non-thermal processing technologies, such as dynamic and hydrostatic high-pressure, vacuum impregnation, ultrasound, pulsed electric field and cold plasma applications, can result in a less negative effect with respect to the traditional thermal treatments, and, in some cases, the overall functionality can be improved. In many cases, these treatments can induce structural changes that improve the bioaccessibility and/or the bioavailability of bioactive compounds such as probiotic microorganisms. Moreover, non-thermal pretreatments, also combined with mild thermal drying technology, could lead to a significant reduction in the total request of energy, even when considering the energy input for their application. A selected review of results published in the last few years on those strategies is presented, considering studies carried out within the frame of different national and EU projects.
在关于食品加工的辩论得出超加工产品的负面定义之后，可以通过共同创造旨在增进人类健康、提高安全性和可持续性的新食品解决方案来推动食品体系的改善，特别是通过使用被忽视的食品原料、作物或副产品，并应用温和的加工技术。妥善管理温和/非热加工技术，如动态和静水压高压、真空浸渍、超声、脉冲电场和冷等离子体应用，与传统热处理相比，可能产生较小的负面影响，并且在某些情况下，整体功能可以得到改善。在许多情况下，这些处理可以引起结构变化，从而提高生物活性化合物（如益生菌微生物）的生物可及性和/或生物利用度。此外，即使考虑到应用非热预处理所需的能量输入，将其与温和的热干燥技术相结合，也可能导致能源总需求显著降低。本文对过去几年在不同国家和欧盟项目框架内开展的研究中发表的有关这些策略的结果进行了精选综述。
