Fashionable technocrats have discovered plenty of tactics to break our meals — like speedy heating of milk as much as 240 levels, zapping with microwaves, irradiating with radioactive fabrics, spray drying at excessive temperatures, extruding at excessive temperatures and pressures and embalming with sugar. Now a brand new generation has come at the scene: ultra-high strain implemented to numerous meals for people, pets and young children.
HPP — Top Drive Processing
Top Drive Processing (HPP) is outlined as “a non-thermal meals and beverage processing method in accordance with the appliance of excessive ranges of hydrostatic strain transmitted via water, with more than one benefits for meals and beverage corporations.” That strain is 1000 instances the strain of air at sea degree — the an identical of water strain in a marine trench.
You’ll be able to learn all about it at hiperbaric.com and spot the way it works for juice, for shelf solid foods waiting to devour, and for “uncooked” dog food. HPP will open oysters with out tricky shucking — after the processing, simply open along with your hand and the oysters — moderately discolored — slither out! The method makes crab and lobster more uncomplicated to take away from their shells.
Examples of high-pressure processed merchandise commercially to be had within the U.S. as of late come with fruit smoothies, guacamole, ready-to-eat foods with meat and greens, oysters, salad dressing, hummus, ham, rooster strips, fruit juice, salsa and fruit purees for young children. You received’t in finding any specific image displayed (as for irradiation) to suggest whether or not a product has gone through HP processing, however you may see the phrases “bloodless pasteurized.”
The meals business claims that “HPP has the prospective to provide fine quality meals that show traits of clean merchandise, are microbiologically protected and feature a longer shelf lifestyles.” The declare that HPP meals are “microbiologically protected” isn’t precisely proper.
What Are the Lengthy-Time period Well being Results of Consuming HPP Meals?
A 2008 evaluate1 entitled “Top-pressure processing — results on microbial meals protection and meals high quality,” appeared on the results of excessive strain processing on more than a few pathogenic organisms and located that it didn’t do away with they all; the researchers discovered that spores have been particularly immune to excessive strain — simply as they’re immune to warmth.
However what we truly need to learn about are the well being results — long-term well being results — of consuming HPP meals. Because the business plunges headlong into excessive strain processing, nobody truly is aware of.
No research on long-term the feeding of HPP meals to mice or rats — and even canines getting HPP “uncooked” dog food — seem within the literature. I did in finding one find out about, revealed within the Magazine of Dairy Science, 20192 which explored the feeding of HPP colostrum to calves. Stated the researchers:
“The result of this find out about counsel that top strain processing of bovine colostrum maintains a suitable IgG degree whilst reducing bacterial and viral counts,” but in addition noticed:
“Calves fed pressure-processed colostrum had an identical serum IgG however decrease potency of absorption than calves fed heat-treated colostrum [emphasis added]. Adjustments in viscosity every so often made calf feeding harder, however nonetheless possible. Further analysis to optimize this generation for on-farm use is essential.”
The meals business is salivating over the speculation of making use of HPP to take advantage of. The primary to try this used to be the Mexican corporate Villa de Patos, which claimed that it used to be “recent” (this is “uncooked”) and had an greater shelf lifestyles when refrigerated.
HPP Dairy Revel in
A couple of years later, the New South Wales Meals Authority licensed the commercialization of HPP milk within the Australian state. The corporate, Made Via Cow, evolved a procedure for the “protected manufacturing of by no means heated and non-homogenized milk,” which they might promote as “protected uncooked milk.” Certainly, the processing made the milk quite thicker and yellowish, which might mimic the viscosity and colour of Jersey milk although it got here from Holstein cows!
With uncooked milk gross sales booming, and pasteurized milk gross sales declining, we will be expecting to peer the dairy business release “cold-processed” pressure-treated milk within the U.S. Will this milk have the similar advantages as actual uncooked milk? A letter revealed within the Summer season 2021 factor of Smart Traditions3 signifies that the solution is not any!
“For a few years I’ve been consuming uncooked milk from a pastured dairy in France known as Gaborit,” wrote our correspondent. “Then again, on account of COVID and closed borders, I used to be not able to procure this milk for 11 months and used to be pressured to drink a change milk from Switzerland.
Once I started to have bother with my tooth, I started to suspect the chance that the native ‘uncooked’ milk (Rohmilch in German) could be thermized (heated) even supposing to not the temperature of pasteurization (or in all probability microfiltered or no matter).
What maximum aroused my suspicions used to be the enjoy of a pal, supposedly milk illiberal (and who hasn’t inebriated animal milk for a just right 20 years), who sneezed (pink eyes as an advantage) a couple of mins after having taken a sip of this ‘native’ Rohmilch.
She made it transparent to me how annoyed she used to be via this enjoy, and she or he fervently blamed herself for giving in to my recommendation. Then again, I will have to admit that I used to be the primary to be stunned via the response she evolved so briefly after ingesting only one sip. I had concluded that she used to be in all probability some of the only a few individuals who have been in reality illiberal to animal milk, although it have been uncooked.
However, a couple of weeks later, she agreed to check the Gaborit milk (from Jersey cows), which I once more had get right of entry to to. She no longer most effective had no response to it, however she even felt so just right that she drank an entire glass part an hour later.
All over the 11 months with out the Gaborit milk, I evolved 5 small cavities, as verified via my dentist. I had an appointment to have them crammed, and whilst ready, used to be in a position to get the French milk once more. I went to the dentist as of late and she or he couldn’t consider her eyes.
Within the area of lower than a month throughout which I used to be as soon as once more in a position to procure the actual qualified uncooked milk from France, the entire prior to now broken tooth had calcified and hardened as a type of self-healing, to the purpose that she instructed me that there used to be not anything extra that had to be finished.
The milk produced via the Swiss dairy is biodynamic and has the Demeter label. The cows are brown Swiss. I due to this fact think that the cows are fed in line with anthroposophical pointers. Then again, this dairy additionally produces pasteurized milk, so I questioned whether or not their Rohmilch is truly 100% uncooked and, above all, non-thermized.
Once I contacted them, they confident me that the milk used to be no longer heat-treated by any means, most effective that they handed it via a cellulose membrane aimed to take away any impurities or grime from the milk — however I believe that is finished with all milk and isn’t a dangerous procedure until finished beneath excessive strain.”
We have no idea whether or not this milk used to be handed beneath strain via a membrane or subjected to the similar excessive strain processing tactics now used for juice, smoothies and such a lot of different “bloodless processed” meals, however it’s transparent that strain reduces the curative homes of Nature’s very best meals.
Since we haven’t any thought what HPP does to the dietary qualities of the meals we devour, it’s very best to workout warning: make your personal salad dressing, salsa and guacamole, cook dinner from scratch, most effective purchase oysters which were shucked earlier than you, and above all, stick with actual, uncooked milk bought without delay from a farmer you understand.
