An edible wrapping paper made of milk extract

It seems to be a new gimmick in the packaging industry to make food packaging, especially those non degradable plastics, edible materials We have previously reported that bakeys, an Indian start-up, made a spoon out of sorghum, which can not only decompose naturally, but also consume very little energy to produce sorghum spoon These researches and inventions have also brought some new ideas to the "non-technical business": KFC in the UK has designed an edible coffee cup (though it is not listed yet), which is more like a kind of marketing; the dirty, a dessert shop in California, USA Cookie's introduction of a sweet food that makes milk and biscuits bound together is actually the invention of an interesting new way to eat sweets Someone wants to make a substitute for plastic wrap again Several scientists at the USDA Institute used casein from milk to make a kind of film paper for food packaging Compared with traditional plastic paper and plastic film, it can biodegrade naturally It is said that another advantage of the film is that its anti-oxidation effect is 500 times stronger than that of ordinary plastic film According to Laetitia bonhailie, a chemical engineer who is in charge of the project, the casein film paper feels like plastic, but its ductility and elasticity are not as good as some plastics There are some edible starch packaging paper on the market, but there are more holes in the ingredients of starch packaging paper, which will let the air penetrate The packaging paper of casein material has smaller pores, which can better isolate air and keep fresh They also designed other uses for casein (how much they love it): instead of sugar powder, for example, sprinkle it on breakfast cereals and biscuits to keep them dry It can also be sprinkled under the pizza box to prevent oil from coming out, or used to make tea bags You may be worried about the cost Laetitia says they use the remaining milk powder reserve in the United States to make films, so the cost is not high There is no flavor in casein, and they plan to launch seasoning casein wrapping paper in the future At present, a company in Texas has begun to use the casein film for food packaging This kind of film is likely to start mass production within three years and officially come out If it is eaten directly, the "milk paper" may not be clean The outer layer may be touching some strange things (including your dirty hands!) Of course, the spoon made of sorghum and the cup made of biscuit also have such problems If you add a layer of wrapping paper to the film for eating, it seems that it's not so environmentally friendly again If you do get a casein wrapper, the best way to eat it is to throw it away (don't stuff your stomach with everything you can eat) Edible properties are more of a gimmick in these products According to Shilpa rosenberry, senior director of global consumption strategy at Daymon worldwide, a food industry consulting company, "edible packaging represents a global consumer's thinking and realm, especially in the environmental awareness of sustainable development and life simplification." So you see, at least for now, it's not a promising solution.
