Knowledge

Aseptic packaging for food and beverage comes in two categories: high acid and low acid. High-acid products include fruit beverages and processed fruits and vegetables, while low-acid products often consist of dairy-based beverages or RTD beverages without fruit juice.

Beverages

Fruit-based beverages, such as cartons of kids' juice drinks, are a major application for aseptic packaging. But dairy-based beverages - ranging from conventional milk-based drinks and protein shakes to non-dairy milk alternatives, such as almond and soy milk - are also using it. RTD tea and iced coffee, flavored waters, and cocktail and bar mixes could also benefit from aseptic packaging.

While tea is naturally a low-acid beverage, most of it is produced in high-acid hot-fill plants, requiring manufacturers to make significant modifications to the 'tea leaves plus hot water' product. Producers can avoid adding acid—and sweeteners to balance the flavor—by using aseptic cartons. The result is a delicate, high-quality tea with a very short list of ingredients: tea and water.

This type of packaging may also serve the growing demand for liquid meal replacements, including smoothies and breakfast drinks. Shelf stability enables retailers and consumers to store the product longer and more easily until they're ready to sell or consume it, while providing the added convenience of being able to drink a meal's worth of nutrients on the go.

Food

Broth and soup, particularly those with particulates, are among the most common food applications for aseptic packaging. As consumers demand more nutrient-filled foods, manufacturers create more processed vegetable products. The high-acid, tomato-based products such as diced tomatoes and sauces could especially benefit from aseptic packaging.

On the more indulgent side, particularly those often found next to fruit cocktails in grocery stores, are using more aseptic packaging.
