4、ent to maintain current levels.Sustainability is becoming a necessity.3D food printing could probably contribute to the solution.Some experts believe printers could use hydrocolloids (水解膠體) from plentiful renewables like algae (藻類) and grass to replace the familiar ingredients (烹飪原料).3D printing can

5、 reduce fuel use and emissions.Grocery stores of the future might stock “food” that lasts years on end,freeing up shelf space and reducing transportation and storage requirements.

7、has many challenges to overcome.Currently,most ingredients must be changed to a paste (糊狀物) before a printer can use them,and the printing process is quite time-consuming,because ingredients interact with each other in very complex ways.On top of that,most of the 3D food printers now are restricted

8、to dry ingredients,because meat and milk products may easily go bad.Some experts are skeptical about 3D food printers,believing they are better suited for fast food restaurants than homes and high-end restaurants. 【語篇導讀】本文是一篇說明文。文章主要介紹了一項新的3D食物打印技術,包括食物打印的省時高效的特點、所使用的原料的可持續(xù)性、提供顧客所需要的營養(yǎng)以及目前技術推廣面臨的挑戰(zhàn)
