As food science and our understanding flora proteins expands by leafs and stem , some food - thinking entrepreneurs are looking for slipway to make our agricultural products safer , more environmentally sustainable , more humane , and yes , cheaper . of late , I paid a visit to food scientific discipline startupHampton Creek Foodsto learn about one such undertaking : the quest to make an egg out of industrial plant protein .
I first heard about Hampton Creek Foods ’ labor , Beyond Eggs , ina post on the sustainability blog Inhabitat , and when I mentioned it to a vegan friend , she quickly put me in touch with someone from the company . Next thing I know , I had an appointment to tour the Hampton Creek Foods quickness and taste eggless cookies and mayo .
The facility is planted in San Francisco ’s SoMa neighborhood , in a spot filled with soundbox shops and package startup . And when I walk through the door , Hampton Creek Foods did indeed search a lot like a software startup . It ’s a small but efficiently used blank , where you ’re straightaway greeted by the glow of Apple screens and a favorable Golden Retriever ( Jake , who was introduced as an official taste examiner ) . But or else of standing workstation , the myriad laptops are propped up on kitchen scales . The piece of work tables are carry not with desk toys but Kitchenaid mixers . Instead of a syndicate table , there ’s a program library of mayonnaise . And or else of cooking up software , the employees are broil cakes in test tubing .
“ We think that our food system is broken , ” excuse Joshua Tetrick , Hampton Creek Foods CEO , “ and break up from the inside out . And we do n’t just suppose that it ’s break in the United States , but breach all over the world . ” Tetrick says that he was interested in tackling one facial expression of the animal agricultural manufacture — from which the Food and Agriculture Organization of the United Nations estimates 18 percent of all nursery emissions stream — and improve it through skill . He selected the barrage John Milton Cage Jr. eggs . “ Now , I ’m not talking about complimentary range [ eggs ] , ” he says . “ I ’m not even utter about John Cage gratis . And our explicit focus is the battery John Cage egg . We ’re trying to focalize on the most abusive , the most environmentally unsustainable , the most inhumane , the most food safety issue . ”
The trouble , Tetrick enjoin , from a consumer standpoint , is that a somebody who is concerned with the welfare of hens might make the effort to buy free - range or coop - free eggs . But one - third of nut lay in the US land not in cartons but in food ware : cooky , muffins , mayo , salad dressings . “ Cruelty thrives on this abstractedness , ” says Tetrick . “ And nothing is more abstract than eat a chocolate chip cookie with a battery cage egg embedded inside it . ” To that end , Tetrick and his colleagues at Hampton Creek Foods are trying to make an nut substitute made entirely out of plant that can perfectly take the place of eggs in all of those food products .
It ’s not an sluttish task , however , because the ball is such an awe-inspiring food for thought item . “ Who would have know that , ” Tetrick break , “ and I ’m sorry to be crass about it — the end result of a hen ’s ovulation cycle would do so many amazing things in food ? It have a muffin to rise , rock oil and H2O to hold together in an emulsion .
Rather than endeavor to copy all of the features of the egg all at once , Hampton Creek Foods is alternatively endeavor to replicate how eggs function in specific products . Tetrick vaunt an egg that works particularly well in cookies and another that make delicious muffins . Plus , they ’ve had achiever with mayonnaise and decorate that mops the trading floor with Vegenaise ( more on that later on ) . Their end is to eventually create a single product that can officiate as well as an egg for every determination .
It ’s a lofty end , one that produce the how more interesting than the why . Hampton Creek Foods has meet a divers team : molecular biologists with backcloth in HIV gene therapy research , vaccines , and sponge - target drugs ; food scientists with a heat for emulsion and bake ratio ; Chris Jones , former Chef de Cuisine at Chicago ’s MOTO Restaurant ( and , for fans of Top Chef , a Season 9 contestant ) .
food for thought scientist Megan Clements explicate how these different backgrounds work in the research lab :
Chris can tinker with a lot of different gums because he ’s intimate with them from the gastronomy world and then I can help him contrive a response - surface methodology experiment with five variables change at the same time so we can see how they involve each other . And we can reach out to Josh [ Klein , senior scientist in protein inquiry ] and say , “ What ’s going on at the port of the crude - water droplet ? What are the protein configurations doing to the flexibility of the film that ’s modernise ? ” And he can bring that protein by to a thick level than is in my background .
But it all starts with that protein . Klein , who heads up the protein team , likens their work to the work of a pharmaceutic company . Just as a pharmaceutical fellowship keeps a program library of compound and their software , his squad is working to build a library of plant protein and their functions . One plant protein might be particularly good at emulsifications ; another might work particularly well in a meringue . There wo n’t be one exclusive plant that answer all of functions of an egg , but by identify and testing the functions of individual plant proteins , they trust to eventually conflate them into the ideal egg second-stringer . Klein would n’t unwrap which proteins they have had particular succeeder with , but he did say that some plants had proven especially fruitful in this section . And they are n’t needfully plants that one would intuitively suspect of being honest egg reserve . “ So far , we ’ve been surprised , ” Klein allege . “ We would n’t have just intuitively gauge [ which plant would mold well ] . That ’s what makes it a challenge — a playfulness challenge . If it were visceral , it would n’t be science . We have to design experiment around it . ”
The testing phase is where things ( potentially ) get tasty . The proteins team will make diminutive patty in test tube to test the functions of single proteins , but the baking team experiments with the ratios in an attempt to create something that will bear like an ball when bake into anything from a cookie to a loaf of bread bread . The company ’s electric refrigerator are backed with various doughs , each labeled and date , to compare how each eggless rendering stacks up against its egg - fill up similitude .
So how does skill appreciation ? My fellow taster ( alias “ my mom ” ) and I did a unreasoning taste test of four different cookies made with two dissimilar recipes ( chocolate bit and chocolate with lily-white deep brown chips ) . In the case of each formula , one cooky was made with orchis , the other with the company ’s Beyond Eggs for Cookies . Otherwise , the recipes were monovular . Here ’s how it shake out :
Beyond Eggs for Cookies is meant as a single backup man for eggs in cookie recipes ; the estimation is that consumers would swop out their ball but keep their recipe the same in all other regard . At the minute , they have no such fill-in for egg whites and yolks , although substitutes are in the works . We also got to taste one of the advantages of ballock - costless cooky making : dough that you may eat without care about salmonella .
That brings us to the emulsions team , who seem to be have more fun with mayonnaise than anyone has any right to be receive . One of the more marvelous abilities of eggs is their powerfulness to hold in oil and water unchanging , lending mayo that incredible shelf aliveness . For each possible egg replacement , the emulsions team read the chemical mechanism of the emulsions and how they break down over prison term , tracking the military force being exerted on the fossil oil droplets in the emulsion , how the gums are interacting , how viscous the photographic emulsion is . Several times , Jones marvels at the way the emulsion squad is capable to quantify what he , as a chef , is see in the photographic emulsion . Clement , who heads the emulsion squad and whose middle ignite up with excitement when excuse the unexpected behavior of a protein in an emulsion , shows off her experiments . She keeps a chamber at dissimilar temperature to study how different formulation of mayonnaise break down over time . She taper to the mayonnaise library , where Hampton Creek Foods keep their myriad mayonnaise . ( She jokes that her apocalypse selection program involves holing up in the office and seeing how long she can live on mayo . ) She uncaps one of the sample mayonnaises and squeezes the jar . The emulsion breaks apart in the middle like a nut of mozzarella . Clement grins and explains it was made from a white potato protein .
The mayonnaise and binding do n’t get a blind taste test , but the taste impressive nevertheless . To my testicle salad - loving palate , the mayonnaise tastes like specially good mayo , and Jones and the emulsion team are clearly lofty of the upshot . I ’ve never had Vegenaise before , but I taste it for comparison and I ’m surprised by how tenuous and acidic it is . ( For the book , some vegan friend of mine tried the same appreciation test and prefer the Vegenaise . )
Tetrick excuse that Hampton Creek Foods presently works with packaged food companies to get eggless versions of their exist products , although the squad has originate a few recipes of their own . He says that the protein in Beyond Eggs is comparable to the protein in substantial eggs , with a remainder of 0.1 percent . He also hopes that Beyond Eggs will be beneficial to those with egg allergic reaction ; although the squad does not yet know if any person will hurt allergic reaction to Beyond Eggs , the squad is not using protein from any of the allergen the FDA legally requires food for thought manufacturers to list on packaging — not monkey nut , no tree nut , no straw , no soy . And without the price of maintain wimp , he claim that Beyond Eggs will be cheaper than testis from a biddy .
The team is also make on a merchandise that will misrepresent like a scramble egg , and Tetrick show us TV of a very other image . Although the product depend like throw together testicle in the genus Pan , Tetrick admit they ’re not ready for meridian time . “ If we wanted to cheat , we ’d have you eat them decently away , ” he say . regrettably , after about a moment , the scrambled Beyond Eggs deflate .
There ’s clearly a band of passion on the Hampton Creek Foods squad , and the foods they make on the assumption were telling . But there ’s a crowing deviation between consuming a intersection in someone else ’s cookery and using the Cartesian product yourself . Hampton Creek Foods station me home with a sampling pack of Beyond Eggs for Cookies . Unfortunately ( having nothing to do with the Cartesian product itself ) , it did n’t go quite as I had hoped :
Thanks to Hampton Creek Foods for letting me tour their facility , and if you happen to be in the region of 10th Street and Harrison in San Francisco , you might get pulled in for a cooky tasting mental testing . I urge it .
