What Is a Shelf Offering?

Heat-treating a high-moisture product allows it to maintain a long shelf life at room temperature. This product is called a shelf stable product (SSP). Products with stable shelves have many advantages, including mild heat treatment (70-110 ° C), which is beneficial to improve the flavor and nutritional value of the product; cold chain is not needed during transportation and sales, and energy is saved; packaging can prevent secondary pollution.

Heat-treated products with high moisture content can keep them long at room temperature

The tomato juice made from Guangdong tomatoes after being heat-treated in boiling water for 3 minutes was crushed and beaten as the research object. The effects of different packaging materials, storage temperature, light, and sterilization treatment on the soluble solids content, pH value, and V _c content of tomato juice influences. Studies have shown that packaging with high oxygen-barrier packaging materials or sterilization or low-temperature storage can reduce the loss of soluble solids content in tomato juice, while packaging with oxygen and light high-barrier packaging materials can reduce V _c The content decreases, but bactericidal treatment will cause some loss of V _c . Therefore, tomato juice is packaged with high oxygen-barrier and light-blocking materials and stored at a lower temperature, which can effectively protect its soluble solids and Vc content, while maintaining a stable pH value ^[1] .
