Notes:
Tomato pulp recovered from acidified and screened caustic (sodium hydroxide) peelings obtained from rotating rubber disc peelers at a cannery in 1975 was found to be a potential food material. However, this pulp contained high levels (150-450 ppm) of peeling aids used in commercial caustic baths; these are not approved food additives. In the spring of 1976, a preliminary study evaluated 50 compounds and various procedures for their peeling aid efficiency. Compounds tested included carboxylic acids (C2-C1 8) and their esters and salts and other surfactants, emulsifiers, and proprietary mixes. The most effective and acceptable peeling aids were C2-C8 saturated fatty acids. For the processing variety, VF145B-7879, the most effective peeling was with a pretreatment of 0.5% octanoic acid at 65°C for about 1 mm, followed by the usual caustic immersion. This was at least as effective as using the octanoic acid directly in the caustic bath.
