There are tactics other than preservatives to make bread last, such as covering it, freezing it, and tangzhong: https://www.kingarthurbaking.com/blog/2018/03/26/introductio...

I tend to bake two loaves (always with tangzhong if the particular recipe can tolerate it), wrap both, immediately freeze one, and the other one lasts somewhere short of a week.
