Recent development has made possible machines that print, cook, and serve a large number of foods. And the industry(产业) isn’t stopping there.

Food production

With a 3D printer, a cook can print complicated(复杂的) 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 Food printer to “re-create forms and pieces” of food that are “exactly the same,” freeing cooks to finish 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 world’s population(人口) is expected to grow to 9.6 billion by 2050, and some experts estimate (估计) that food production will need to be raised by 50 percent to keep present levels(水平). Sustainability is becoming a necessity. 3D food printing could probably help solve the problem. Some experts believe printers could use hydrocolloids (水解胶体) from rich renewable materials(原料) like algae and grass to replace(代替) the ingredients(烹饪原料). 3D printing can reduce fuel use and emissions(排放). The stores of the future might store "food" that lasts for years, freeing up shelf space and reducing transportation and storage requirements.

Nutrition(营养)

Future 3D food printers could make food healthier. Hod Lipson, a professor at Columbia University, said, “Food printing could allow customers(消费者) to print food with customized(定制的) 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(要求).”

Challenges

Though there are great developments in 3D food printing, the industry has many challenges to overcome. Most ingredients must be changed to a dry powder(粉末) before a printer can use them, and the printing process takes a lot of time, because ingredients interact (相互作用)with each other in very complex ways. Besides, most of the 3D food printers now use only dry ingredients, because meat and milk products may easily go bad. Some experts doubt about 3D food printers, believing they are more suitable for fast food restaurants than homes and high-end restaurants.

1.What advantage(好处) does 3D printing bring to food production?

A.It teaches cooks to create new dishes. B.It saves time and effort(努力) in cooking.

C.It improves the cooking conditions. D.It helps to decorate the restaurants.

2.What does the underlined word “raise” mean in paragraph 3?

A.募集 B.导致 C.培育 D.增加

3.According to Paragraph 4, 3D-printed food ________.

A.is easier for consumers to get B.can meet personal nutritional needs

C.is tastier than food in supermarkets D.can keep all the nutrition in raw(生的) materials

4.What is the main factor(因素) that prevents 3D food printing from spreading widely?

A.The printing process is not long. B.3D food printers are too expensive.

C.Food materials have to be dry. D.Some experts doubt 3D food printing.

5.What could be the best title of the passage?

A.3D Food Printing: Delicious New Technology B.A New Way to Improve 3D Food Printing

C.The Challenges for 3D Food Production D.3D Food Printing: From Farm to Table
