Can you use HPP with glass bottles?
HPP is done on juice that has already been pressed and bottled in plastic bottles. HPP does not work on glass bottles, because glass cannot withstand the force without breaking.
Which type of packaging materials are more suitable to process food by HPP give examples?
Plastic bottles, pouches, cups, and trays made of PET, PE, PP and EVOH (or combinations thereof) work very well with HPP due to their good water barrier properties and flexibility.
What is glass used for packaging?
Glass is extensively preferred as a packaging material due to its properties like recycling reuse and neutral reacting nature. It preserves food and beverages for a long term and avoids contamination. For example, beer is stored in dark glass bottles to avoid spoilage.
Which food categories is HPP most effective?
HPP is suitable for foods that have a high water content. It is particularly useful for raw foods, when retention of fresh characteristics is important, as the treatment does not significantly alter flavour, texture or appearance.
What are HPP bottles?
HPP bottles are specifically designed to hold up to high-pressure processing techniques. Cold press bottles that are HPP compliant help protect contents from harmful bacteria while preserving color and taste.
How much does HPP cost?
To purchase and set up one HPP machine, it costs nearly $3 million. Plus, once you have the machine, you need a 24-hour support team for maintenance. Every night there is a two-hour breakdown for maintenance—oiling valves and such. It’s expensive, but we think it’s completely worth it.”
What is HPP packaging?
Simply stated, HPP is a technique by which food and beverage products, already sealed in final packaging, are introduced into a cylinder-shaped pressure chamber where they are subjected to a high level of hydrostatic pressures (43,500-87,000 pounds per square inch) transmitted by cold water.
What is HPP used for?
High-pressure processing (HPP) is a “nonthermal” food preservation technique that inactivates harmful pathogens and vegetative spoilage microorganisms by using pressure rather than heat to effect pasteurization.
What are glass bottles used for?
Common uses for glass bottles include food condiments, soda, liquor, cosmetics, pickling and preservatives. These types of bottles are utilitarian and serve a purpose in commercial industries.
How is HPP applied to foods?
HPP is a non-thermal method of preservation in which a solid or liquid food is placed in a pressure vessel and subjected to very high pressure using a pressure-transmitting medium (usually water). HPP can inactivate vegetative microorganisms and enzymes in the food and alter certain characteristics of the food.
What is HPP compatible?
What are HPP bottles and why are they important?
HPP bottles are specifically designed to hold up to high-pressure processing techniques. Cold press bottles that are HPP compliant help protect contents from harmful bacteria while preserving color and taste. Order bulk beverage bottles to keep production moving and help prevent the introduction of foreign materials to sitting batches of product.
How high pressure can packaging withstand?
Packaging not only extends the shelf life of foods but protects the products from detrimental external agents like chemical compounds or spoilage microorganisms. And combined with high pressure (HPP) lengthens the shelf life as well. Although, many food industries wonder if their current packaging would withstand pressures of up to 6,000 bar.
What is high pressure processing (HPP)?
High pressure processing (HPP), due to the physical aspects inherent to hydrostatic pressures and their effect on pathogenic and altering microorganisms, already significantly increases the shelf life of the product. All this, while preserving the organoleptic and nutritional properties.
What are the different packaging materials used in HPP?
1 Material: due to its good flexibility, elasticity and water barrier properties, plastics are commonly used as packaging material in HPP products. 2 Packaging system: vacuum, modified atmosphere… 3 Manufacturing process of the container: by injection or by thermoforming. 4 Labeling: Containers can be pressurized without and with labels.
