Many people do not realize that seasoning products also require thermal sterilization during production.

Products such as hot pot bases, chili sauces, seasoning pouches, and compound sauces may contain high salt content, but for shelf-stable storage and longer shelf life, choosing the right retort system has become increasingly important for food manufacturers.

Especially for pouch-packed seasonings, insufficient sterilization may cause swelling, oil separation, discoloration, or affect product quality during transportation and storage.

For these products, DTS recommends using a spray retort system for thermal sterilization.

A spray retort uses circulating hot water to evenly distribute heat around the packages, helping improve seasoning sterilization consistency while minimizing impact on product color, aroma, and texture.

One customer producing spices and compound seasonings reported clear improvements after introducing the DTS spray retort:

✔ More stable product color
✔ Better package integrity
✔ Shelf life extended to over 6 months
✔ Higher production efficiency

For food manufacturers, choosing suitable thermal sterilization equipment is not only important for food safety, but also for stable product quality and market competitiveness.

As quality requirements continue to rise in the seasoning industry, spray retort systems are becoming an important part of modern seasoning production.
