纳米技术在食品领域中的应用 总被引:8,自引:0,他引:8
一、纳米和纳米技术 纳米是长度单位,1纳米(nm)=10-9m.从微观角度来看,1nm大约相当于10个氢原子的大小.研究表明,细微颗粒进入纳米量级(1~100nm)时,其本身则具有表面效应、体积效应、尺寸效应和量子隧道效应,导致纳米体系的光、电、热、磁等物理性质出现许多新奇特征. 相似文献

Nanotechnology is becoming increasingly important for the food sector. Promising results and applications are already being developed in the areas of nutrient delivery systems through bioactive nanoencapsulation, biosensors to detect and quantify pathogens organic compounds, other chemicals and food composition alteration, and even edible film to preserve fruit or vegetables. This article reviews the application and the benefits of nanotechnology in different areas of food industry that include bioactive nanoencapsulation, edible thin film, packages and nanosensors. It is possible to conclude from the review that the nanotechnology advances increase the safety and quality of food and mainly decrease the time for pathogen detection. 相似文献

The NanoRelease Food Additive project developed a catalog to identify potential engineered nanomaterials (ENMs) used as ingredients, using various food‐related databases. To avoid ongoing debate on defining the term nanomaterial, NanoRelease did not use any specific definition other than the ingredient is not naturally part of the food chain, and its dimensions are measured in the nanoscale. Potential nanomaterials were categorized based on physical similarity; analysis indicated that the range of ENMs declared as being in the food chain was limited. Much of the catalog's information was obtained from product labeling, likely resulting in both underreporting (inconsistent or absent requirements for labeling) and/or overreporting (inability to validate entries, or the term nano was used, although no ENM material was present). Three categories of ingredients were identified: emulsions, dispersions, and their water‐soluble powdered preparations (including lipid‐based structures); solid encapsulates (solid structures containing an active material); and metallic or other inorganic particles. Although much is known regarding the physical/chemical properties for these ingredient categories, it is critical to understand whether these properties undergo changes following their interaction with food matrices during preparation and storage. It is also important to determine whether free ENMs are likely to be present within the gastrointestinal tract and whether uptake of ENMs may occur in their nanoform physical state. A practical decision‐making scheme was developed to help manage testing requirements. 相似文献
