The Chemist’s Recipie for Chocolate Chip

The following recipie for chocolate chip cookies recently appeared in Chemical & Engineering News (C&EN, Jun 19, 1995, p. 100). It was attributed to Jeannene Ackerman of Witco Corp.
1 532.35 cm3 gluten
2 4.9 cm3 NaHCO3
3 4.9 cm3 refined halite
4 236.6 cm3 partially hydrogenated tallow triglyceride
5 177.45 cm3 crystalline C12H22011
6 177.45 cm3 unrefinedCl2H22011
7 4.9 cm3 methyl ether of protocatechuic aldehyde
8 Two calcium carbonate-encapsulated avain albumen-coated protien
9 473.2 cm3 theobroma cacao
10 236.6 cm3 de-encapsulated legume meats {sieve size #10)

To a 2-L jacketed round reactor vessel {reactor #1) with an overall heat-transfer coefficient of
about 100 Btu/F-ft2-hr add one, two, and three with constant agitation.

In a second 2-L reactor vessel with a radial flow impeller operating at 100 rpm add four, five, six, and seven until the mixture is homogeneous.

To reactor #2 add eight followed by three equal portions of the homogeneous mixture in reactor #1. Additionally, add nine and ten slowly with constant agitation. Care must be taken at this point in the reaction to control any temperature rise that may be the result of an exothermic reaction.

Using a screw extrude attached to a #4 nodulizer place the mixture piece-meal on a 31655 sheet {300 x 600 mm). Heat in a 460K oven for a period of time that is in agreement with
Frank & Johnston’s first order rate expression {see JACO5, 21, 55), or until golden brown.

Once the reaction is complete, place the sheet on a 25 deg. C heat-transfer table allowing the product to come to equilibrium.
