plantbased alternatives to cow milk, including soy, nuts, and coconut milk.these products are popular with consumers who cannot drink cows milk for health reasons, as well as with those concerned about animal welfare and environmental sustainability.while the dairyfree(非乳制的) options work well with cereal or in coffee, they fail miserably when it comes to making milkbased products like cheese or yogurt.however, these shortcomings may soon be a thing of the past, thanks to a new company in california, which has figured out how to create animalfree milk in a laboratory!perumal gandhi and ryan pandya founded the company in 2014 after becoming increasingly annoyed with the lack of cows milkfree alternatives, particularly for cheese.for gandhi, who stopped consuming animal products five years earlier due to environmental and animal welfare concerns, the motivation to create a better alternative stemmed(起源于) from his love of cheesy pizza.pandya was spurred(鼓励) into taking action after being forced to eat some“really bad”dairyfree cream cheese on his sandwich.the two mit biomedical engineering scientists decided to join forces to create a more realistic alternative to dairybased products.in their university lab, the pair spent nine months first isolating cow dna and then inserting it into yeast(酵母)this genetic modification enabled the yeast to produce the necessary milk proteins.the final step of the process involved mixing the proteins with some plant nutrients and fats.the dairyfree milk not only tastes like the real thing but is also healthier, has a longer shelf life and, the most important of all, is earthfriendly.according to the companys website, when compared to conventional milk production, their process uses 65% less energy, creates 84% less greenhouse gas emissions and requires 91% less land and 98% less water! best of all, since it contains real milk proteins, the product behaves like the cowproducing version, which means vegetarian consumers will no longer have to deal with soggy(受潮的) cheese on their sandwiches and pizzas.the company plans to bring their creation to the market later this year and their first product will most likely be cheese since there are already numerous good cows milk alternatives available to consumers.语篇导读本文为说明文。麻省理工学院生物医学工程科学家创立的公司取得了技术突破， 成功研制了非动物乳制品的产品， 并计划生产第一代产品。1the underlined word “those” in paragraph 1
