How to improve quality and safety of raw meat products with HPP

2015 has been an intense year for food industry and its actors and, If there was a Food Oscar ceremony, Salmonella would have won the most recurring pathogenic bacteria of the year category.  With more than 75 FDA recalls in 2015 and 19 recalls at this stage in 2016, Salmonella is becoming a recurring problem alongside Listeria (at a lesser extent) with the increase of fresh/minimally processed & additive-free products. But, isn´t there any solution to conciliate food safety and quality with customer´s demands?wordle_new4 Continue reading

HPP in China & ASEAN. Is it starting to take off?

asia-globoHPP technology is the fastest growing non-thermal processing technology nowadays. It has started a revolution in the market of fresh products, specially fruit juices and other fruit products, where this revolution will be even more evident in the coming years.

This is a relatively young technology and indeed Japan was the first country to adopt and launch HPP products in the market worldwide, using prototype equipment. It happened in 1990 when the company Meidi-Ya launched its Continue reading


One of the questions most commly asked by fresh protein processors, whether it’s meat or fish, is: “can we high pressure process fresh, raw product, in order to extend the shelf life and guarantee the absence of pathogens?”

Well, the answer is YES, you could, BUT… pay attention, because HPP changes completely the color and the texture of the meat. The fresh meat or fish turns much paler, whiter, with a more texturised, gelified apperance. Almost like it had been slightly cooked! Though no thermal treatment has been applied whatsoever.

The reason is that high isostatic pressure, in the same way that inactivates the microorganisms by changing the proteins in their membrames and citoplasm, also causes changes in the raw protein. HPP does not break the primary structure of the protein, but it can fold a protein, changing its 3D structure and shape, and hence modifying the texture and aspect of that protein matrix

Such changes in appearance and texture of the meat pose a big challenge when it comes to marketing HPP “raw” meat. Consumers, in general, will find hard to understand if that differently processed meat is marketed as fresh-like. Why is it so pale? How come can it last that long? Etc

Despite this historical limitation of high pressure technology, several innovators have used HPP in new value propositions.

Campofrío in Spain, for example, developed and marketed “Ready-to-Finalise” turkey and chicken breasts in a marinade. It is a product with long shelf life (35 days), convenient, faster to finalise on the pan or grill because the protein struture had already been transformed in the HPP step.

DIL, a leading technology center in Germany working extensively on HPP applications, developed a method to substitute the thermal step in some products such as the German onion sausage, or the liver sausage, with an HPP step. Yes the sausage could be paler, but more nutritious, faster to manufacture an with important savings in energy. As for the liver sausage, the spreadability was improved, and the liver flavor profile is avoided when eliminating the thermal treatment and using only HPP.

Check out this explanatory video:

Cargill, leading multinational in the protein business (amongst other food segments) has worked very hard to develop HPP beef patties with extended shelf life and increased safety: The Fressure burgers, for foodservice application. In this case, it’s probably easier to explain the chefs and the operators why that pattie is different… but also, why it’s more convenient (refrigerated vs. frozen), safer, and knowing that the final result, once grilled, is all good the same.

Other interesting developments for fresh meat are being worked in Australia by CSIRO-Food Science Australia and the Meat and Livestock Commission there, as well as by Hormel, a leading American meat corporation, for applications of HPP as a slaughterhouse intervention. The objective: using relatively low pressures, literature suggests that meat cuts can be tenderised, and even better, as a pre-rigor mortis step, glycolisis can be inhibited – hence preventing the hardening and acification of fresh meat after slaughtering.

In conclusion, there are several challenges and limitations when it comes to implementation of HPP technology in fresh meat. But also very interesting potentialities and even current truly innovative applications!!


Opening of Donny Boy Fresh Food’s state of the art HPP facility

donny-boy-fresh-foods-inaugura-en-australiaAt a ceremony in Melbourne, the Hon John Brumby, Premier of Victoria, opened first Australian High Pressure Processing (HPP) facility for the manufacture of fruit products, using the industrial installation supplied by NC Hyperbaric. Donny Boy Fresh Food Company manufactures Preshafruit®juices and fruit for retail, food service and industrial applications. HPP fruit, juice and other foods are pressurised cold for freshness (not heat pasteurised). This means fresh taste, colour, texture, nutrition and smell are retained in foods whilst delivering a product with an extended shelf life. All product   development of the Preshafruit products and initial commercial production was   undertaken at Food Science Australia’s (FSA) Innovative Foods Centre.   Representing Spain’s NC Hyperbaric as supplier of this leading edge technology were representatives of the Spanish Embassy in Sydney and Spain’s Consulate in Melbourne.
