Yes, buffered vinegar powder can potentially be used to preserve other foods besides meat.
It could be used in preserving certain types of fruits and vegetables. For example, in pickled vegetables like cucumbers or carrots, the buffered vinegar powder could contribute to their preservation by creating an acidic environment that inhibits microbial growth. It might also be suitable for preserving some dairy products, such as certain cheeses, where the controlled acidity can help prevent spoilage. In baked goods, especially those with a longer shelf life requirement, buffered vinegar powder could play a role in maintaining quality and extending freshness. However, the effectiveness of its use would depend on various factors including the specific food’s composition, processing methods, storage conditions, and the amount of buffered vinegar powder used. For instance, when making homemade pickles, buffered vinegar powder could be added along with other seasonings to ensure the pickles stay preserved for an extended period. Or in a batch of homemade muffins, a small amount of buffered vinegar powder could potentially help keep them from going stale too quickly.
