| This previous discussion linked below on the Ball recommendation explains why it is in that particular book (Canadian publication) and why it is not required by any other source. As the book says: Lemon juice is added to help preserve the apples natural color and to assure the acidity of the finished product since different varieties and harvesting conditions can produce apples of lower acidity. If it is not just a cover their a** inclusion and a color preservative additive as I suspect then only Ball can explain why they included it when no other approved source does. The link below also includes some info from Dr. Andress from NCHFP. As to why not in the apple juice? I would assume it is the very different density aspect. Juice is easily heat processed safely while sauce, given its density (many make it way too thick), MAY be considered "safer" with the lemon added. Windfall apples being the exception since it is required by all when using windfalls. Bottom line - its your choice. Since I never use windfalls and I don't make really thick sauce I never add lemon to either. Dave |
