Long-life cream, also known as ultra-heat-treated (UHT) cream, is a type of cream that has been treated with high heat to extend its shelf life. UHT cream is heated to a temperature of at least 275°F (135°C) for a few seconds to kill any bacteria present in the cream. This process makes the cream shelf-stable, meaning it can be stored at room temperature without the need for refrigeration.
Long-life cream has a longer shelf life compared to pasteurized cream, which requires refrigeration and has a shorter shelf life. Long-life cream can last for several months without spoiling, making it a convenient option for food manufacturers, retailers, and consumers.
Long-life cream can be used in a variety of food applications, including in coffee, tea, desserts, and cooking. However, it may have a slightly different taste and texture compared to pasteurized cream due to the high-heat treatment. Some people also prefer the taste of pasteurized cream, which is not as processed and has a fresher flavor.
Long-life cream is a convenient and practical option for those who require a cream product with a longer shelf life, but it may not be suitable for those who prefer a fresher, less processed taste.
The market scope for long-life cream, also known as ultra-heat-treated (UHT) cream, is significant, as it is used in a variety of food products and industries. Some of the key applications of long-life cream include:
1. Dairy Industry: Long-life cream is an essential ingredient in the production of various dairy products such as ice cream, whipped cream, and custards. In the dairy industry, long-life cream is used to create consistent and safe products that meet industry standards and regulations.
2. Bakery and Confectionery Industry: Long-life cream is used in the production of a wide range of bakery and confectionery products such as cakes, pastries, and chocolates. It is often used as a key ingredient in fillings, frostings, and toppings, to enhance the flavor and texture of the final product.
3. Food Service Industry: Long life cream is used in the food service industry to create a variety of dishes such as soups, sauces, and gravies. It is often used to add richness and creaminess to these dishes, as well as to create a smooth and consistent texture.
4. Retail Industry: Long life cream is available for purchase in grocery stores and supermarkets, and it is often used by consumers for cooking and baking at home. It is also used as a topping for desserts and hot beverages such as coffee and tea.
The market scope for long-life cream is broad and diverse, and it is expected to continue to grow as the demand for convenient and long-lasting dairy products increases. The growing trend of convenience foods and the increasing demand for dairy products in emerging economies are some of the factors driving the growth of the long-life cream market.
Some of the major players in the global long-life cream market:
1. Nestle S.A.
2. Danone S.A.
3. Fonterra Co-operative Group Limited
4. Arla Foods
The commercial production of long-life cream, also known as ultra-heat-treated (UHT) cream, involves several steps, including:
1. Raw material selection: The first step in the production of long-life cream is to select high-quality milk that meets the required standards. The milk is then transported to the processing plant.
2. Standardization: The milk is standardized to the desired fat content, typically between 30-40%, depending on the product specifications.
3. Homogenization: The milk is homogenized to break down the fat globules and create a smooth, uniform texture.
4. Ultra-heat treatment: The milk is heated to a temperature of at least 275°F (135°C) for a few seconds to kill any bacteria present in the milk. This process also sterilizes the milk and extends its shelf life.
5. Cooling: The sterilized cream is then cooled rapidly to prevent any further bacterial growth.
6. Aseptic packaging: The long-life cream is packaged in aseptic containers, which are sealed to prevent any contamination from the external environment.
7. Storage and distribution: The packaged long-life cream is stored and distributed to retailers, wholesalers, and food manufacturers.
The commercial production of long-life cream requires specialized equipment and expertise. The UHT treatment process requires high-temperature processing equipment, and aseptic packaging requires specialized machinery to ensure the integrity of the product.
