متن کاملPectin methylesterase activity and other factors affecting pH and titratable acidity in processing tomatoes
Pectin methylesterase (PME) rapidly hydrolyzes pectin methylesters in cold break tomato juice to form methanol and to increase titratable acidity (TA). Within 30 min, the juice methanol concentration increased from 35 to over 400 lg g 1 while the pH dropped from 4.45 to 4.20. On average, cold break juice pH values were 0.21 U lower and TAs 12.4 leq g 1 higher than those for hot break juices pre...
متن کاملIntracellular Acidity in Valonia
The very large cells of the marine green alga Valonia macrophysa permit one to obtain several cubic centimeters of fluid from the central vacuole of a single cell (cf. Wodehouse, 1917), without involving appreciable alteration in the composition of the cell-sap through protoplasmic 'injury during the process of extraction (cf. Chambers, 1917). Estimations have been made of the acidity of this c...
متن کاملTextural modification of processing tomatoes.
Knowledge of the textural properties of processing tomatoes is crucial to ensuing product acceptability; measurement, control, and optimization of these properties through judicious selection of varieties and control of unit operations results in products that the consumer prefers. It is important to first define the terms texture, rheology, consistency, and viscosity prior to discussing princi...
متن کاملProduction of Processing Tomatoes in California
Background In the early 20 century, processing tomatoes were mainly produced in the eastern U.S. with the leading states being New Jersey, Maryland and Indiana. At that time, the shipping costs from these states to the major markets in the East and Midwest were considerably lower than those for tomatoes produced in California . Despite this disadvantage, production was considerably expanded in ...
