High-Temperature Short-Time (HTST) pasteurization, also known as flash pasteurization or continuous pasteurization, is one of the most widely used methods in the food and beverage industry today. From dairy to juice to plant-based drinks, HTST pasteurisation offers an efficient, reliable, and food-safe way to extend product shelf life without compromising taste or nutrition.
In this article, we’ll walk you through what HTST pasteurization is, explore the six key advantages of pasteurization, and help you understand how to find the right HTST pasteurizer for your business.
What is HTST Pasteurization?
HTST stands for High-Temperature, Short-Time pasteurization. It involves heating liquid food products to a temperature of around 71.5°C to 74°C (160–165°F) for 15–30 seconds, followed by rapid cooling to around 4–5.5°C (39.2–42°F).
Unlike traditional methods, HTST pasteurization does not rely on prolonged heating. Instead, it applies high temperatures for a short duration, killing harmful bacteria such as Listeria, Salmonella, E. coli, and Coxiella burnetii—the most heat-resistant pathogen found in raw milk. This method is commonly used for milk, fruit juice, beer, wine, and various plant-based beverages like soy, almond, or oat milk.
HTST pasteurization is typically performed using a plate heat exchanger, a homogenizer, and a cleanable, stainless-steel modular system designed for continuous production.
6 Advantages of Pasteurization
Kills Harmful Pathogens, Improves Food Safety
One of the primary advantages of pasteurization is its ability to kill pathogenic microorganisms that may be present in raw food and beverages. HTST pasteurization is effective against a wide range of harmful bacteria, viruses, yeast, and mold, helping producers meet strict food safety standards.
By ensuring microbial safety, HTST pasteurization reduces the risk of foodborne illnesses and contributes to consumer confidence in packaged beverage products.
Extends Product Shelf Life
HTST pasteurization significantly extends the refrigerated shelf life of perishable liquids. For instance, HTST-treated milk can be safely consumed for 16 to 21 days, while fruit juices and plant-based drinks benefit from similar shelf-life improvements.
This longevity helps manufacturers and distributors reduce product waste, streamline logistics, and reach wider markets without compromising quality.
Preserves Nutritional Value
Compared to longer, higher-temperature processes, HTST pasteurization retains more vitamins and minerals in the final product. Scientific studies, such as those published in Frontiers in Bioscience, show that HTST is one of the best methods for preserving the nutritional integrity of sensitive liquids like breast milk or juice.
Although some nutrient loss is inevitable with any heat treatment, HTST strikes a balance by minimizing degradation while ensuring safety.
Maintains Original Flavor and Color
HTST pasteurisation uses minimal heat exposure, which helps maintain the natural taste, aroma, and appearance of the product. This is especially important for juices and dairy alternatives, where consumer preferences lean heavily toward fresh, authentic flavor profiles.
HTST pasteurization also helps preserve color — a critical factor for fruit-based beverages and plant milks where visual appeal influences purchasing decisions.
Suitable for Large-Scale Production
Designed as a continuous-flow system, HTST pasteurization is ideal for high-volume manufacturing. From the moment pasteurization starts, the system can run consistently with minimal downtime, making it a cost-effective solution for large-scale production environments.
This efficiency also supports faster bottling, reduced processing times, and better utilization of factory resources.
Easy to Clean and Maintain
HTST pasteurization systems are typically built with sanitary stainless steel, allowing for automated Clean-in-Place (CIP) procedures. These systems reduce contamination risk, minimize labor costs, and keep hygiene standards consistently high.
Regular cleaning and preventive maintenance are straightforward, ensuring long-term durability and system reliability.
