Abstract

Starch is a versatile and a widely used ingredient, with applications in many industries including adhesive and binding, paper making, corrugating, construction, paints and coatings, chemical, pharmaceutical, textiles, oilfield, food and feed. However, native starches present limited applications, which impairs their industrial use. Consequently, starch is commonly modified to achieve desired properties. Chemical treatments are the most exploited to bring new functionalities to starch. However, those treatments can be harmful to the environment and can also bring risks to the human health, limiting their applications. In this scenario, there is a search for techniques that are both environmentally friendly and efficient, bringing new desired functionalities to starches. Therefore, this review presents an up-to-date overview of the available literature data regarding the use of environmentally friendly treatments for starch modification. Among them, we highlighted an innovative chemical treatment (ozone) and different physical treatments, as the modern pulsed electric field (PEF), the emerging ultrasound (US) technology, and two other treatments based on heating (dry heating treatment – DHT, and heat moisture treatment – HMT). It was observed that these environmentally friendly technologies have potential to be used for starch modification, since they create materials with desirable functionalities with the advantage of being categorized as clean label ingredients.

摘要

淀粉是一种用途广泛且用途广泛的成分，可应用于许多行业，包括粘合剂和装订、造纸、瓦楞、建筑、油漆和涂料、化工、制药、纺织、油田、食品和饲料。然而，天然淀粉的应用有限，这损害了它们的工业用途。因此，通常对淀粉进行改性以获得所需的特性。化学处理最常用于为淀粉带来新的功能。然而，这些治疗方法可能对环境有害，也可能给人类健康带来风险，限制了它们的应用。在这种情况下，人们正在寻找既环保又高效的技术，为淀粉带来新的所需功能。所以，本综述提供了有关使用环保处理淀粉改性的可用文献数据的最新概述。其中，我们重点介绍了一种创新的化学处理（臭氧）和不同的物理处理，如现代脉冲电场（PEF）、新兴的超声波（US）技术，以及另外两种基于加热的处理（干加热处理 - DHT，以及热湿处理——HMT）。据观察，这些环保技术具有用于淀粉改性的潜力，因为它们创造了具有理想功能的材料，并具有被归类为清洁标签成分的优势。我们强调了一种创新的化学处理（臭氧）和不同的物理处理，如现代脉冲电场 (PEF)、新兴的超声波 (US) 技术以及其他两种基于加热的处理（干加热处理 - DHT 和热湿处理） – HMT）。据观察，这些环保技术具有用于淀粉改性的潜力，因为它们创造了具有理想功能的材料，并具有被归类为清洁标签成分的优势。我们强调了一种创新的化学处理（臭氧）和不同的物理处理，如现代脉冲电场 (PEF)、新兴的超声波 (US) 技术以及其他两种基于加热的处理（干加热处理 - DHT 和热湿处理） – HMT）。据观察，这些环保技术具有用于淀粉改性的潜力，因为它们创造了具有理想功能的材料，并具有被归类为清洁标签成分的优势。
