The USDA no longer recommends alum in pickles. The alum was used in the past to make pickles crisp (it did not work very well). Most pickle recipes now create crispness by soaking cucumber slices in a salt water brine, kept cold for 6-24 hours. Refer to a modern recipe for making pickles.
The USDA no longer recommends the use of alum in pickle recipes. You can leave it out entirely with no ill effects so long as you follow approved canning methods. Ball makes a product called Pickle Crisp that can be added at the end of the preparation process. I do not use it and have crispy pickles, it's your choice.
According to the USDA, alum may still safely be used to firm fermented cucumbers, but it does not improve the firmness of quick-process pickles. If you use good-quality ingredients and follow current canning methods, alum is not needed. If you do use alum, do not use more than 1/4 teaspoon per quart of pickling liquid. Excess will cause bitterness. For up-to-date canning recipes, contact your local county Extension agency.
Alum can cause stomach problems although it was once used in the pickling process to make pickles crisper. Alum is used in the canning process, particularly for pickles, to provide extra crunch. It is allowed by government agency, but its use is not recommended. Do not use in final product, only in intermediate soaking steps.
Any difference, both are sodium chloride.
The USDA no longer approves of the use or alum of picking lime in the preparation of pickles. Refer to the National Center for Home Food Preservation (NCHFP) website, it is an excellent source for current research-based recommendations for most methods of home food preservation and includes many tested recipes.
