A

(2018·天津，C) There’s a new frontier in 3D printing that’s beginning to come into focus：food. Recent development has made possible machines that print，cook，and serve foods on a mass scale. And the industry isn’t stopping there.

Food production

With a 3D printer，a cook can print complicated chocolate sculptures and beautiful pieces for decoration on a wedding cake. Not everybody can do that—it takes years of experience，but a printer makes it easy. A restaurant in Spain uses a Foodini to “re－create fo rms and pieces” of food that are “exactly the same，” freeing cooks to complete other tasks. In another restaurant，all of the dishes and desserts it serves are 3D－printed，rather than farm to table.

Sustainability(可持续性)

The global population is expected to grow to 9. 6 billion by 2050，and some analysts estimate that food production will need to be raised by 50 percent 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 (水解胶体)from plentiful renewables like algae (藻类) and grass to replace the familiar ingredients (烹饪原料). 3D printing can 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.

Nutrition

Future 3D food printers could make processed food healthier. Hod Lipson，a professor at Columbia University，said，“Food printing could allow consumers to print food with customized nutritional content，like vitamins. So instead of eating a piece of yesterday’s bread from the supermarket，you’d eat something baked just for you on demand. ”

Challenges

Despite recent advancements in 3D food printing，the industry has many challenges to overcome. Currently，most ingredients must be changed to a paste(糊状物) 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 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.

(2018·全国Ⅰ，B) Good Morning Britain’s Susanna Reid is used to grilling guests on the sofa every morning，but she is cooking up a storm in her latest role—showing families how to prepare delicious and nutritious meals on a tight budget.

In Save Money：Good Food，she visits a different home each week and with the help of chef Matt Tebbutt offers top tips on how to reduce food waste，while preparing recipes for under ￡5 per family a day. And the Good Morning Britain presenter says she’s been able to put a lot of what she’s learnt into practice in her own home，preparing meals for sons，Sam,14，Finn,13，and Jack,11.

“We love Mexican churros，so I buy them on my phone from my local Mexican takeaway restaurant，”she explains. “I pay ￡5 for a portion (一份)，but Matt makes them for 26p a portion，because they are flour，water，sugar and oil. Everybody can buy takeaway food，but sometimes we’re not aware how cheaply we can make this food ourselves. ”

The eight－part series (系列节目)，Save Money：Good Food，follows in the footsteps of ITV’s Save Money：Good Health，which gave viewers advice on how to get value from the vast range of health products on the market.

With food our biggest weekly household expense，Susanna and Matt spend time with a different family each week. In toni …… 此处隐藏：5049字，全部文档内容请下载后查看。喜欢就下载吧 ……
