WebJun 1, 1989 · X ray diffraction was used to determine the changes in crystal form due to tempering and length of storage. The crystal forms present in the tempered shortenings are reported in Table 2.The shortening tempered at 30°C for 2 and 9 d had mixtures of beta and beta prime crystals at week 0 and the amount of beta crystals increased by week 5. WebThere are two basic concepts that underlie successful tempering: formation or addition of the correct seed crystals and proper cooling and heating to make certain that these crystals are present in ideal numbers. Seed crystals are beta crystals, which, by growing larger, eventually cause the liquid chocolate to solidify.
