The in vivo dietary fiber contents of wheat milling fractions and wheat foods, determined in rat feeding experiments, were compared with dietary fiber values determined in vitro with pronase alpha-amylase digestion. Both types of dietary fiber values

Strips cut from cold storage (5 C), potatoes were immersed in difluorodichloromethane (R-12) from 5 to 13 sec. This rapid freezing was found to selectively damage only the frozen cells and to increase their permeability with respect to intracellular

Tissue selected from the stem- and bud-end of reconditioned tubers having sugar-end disorder was compared by color after frying and chemical composition to tissue removed from the two ends of tubers without sugar-end disorder taken directly from cold

In an investigation of phenolase-blackspot relationships, experiments were conducted to study sources of variability in phenolase determinations that could account for the inability to get consistent and reproducible data between trials. There was no

Peroxidase and catalase activities in selected potato tuber tissue were studied for differences and possible association with resistance or susceptibility to blackspot. Unbruised stem-end tissue had significantly greater peroxidase activity than did

Potatoes with high-reducing sugar content taken directly from cold storage (4.5 C) and cut into 3/8-inch-square, 3-inch-long strips, were immersed in liquid nitrogen or dichlorodifluoromethane (−30.5 C or−79 C) for 3 to 15 sec and then leached fo

A method for the esterification, extraction, and quantitative gas-liquid chromatography of lactic, pyruvic, fumaric, succinic, malic, and citric acids has been described. The effect of temperature variation on extraction is discussed and optimum cond

The rate of oxidation of tyrosine, p-cresol and catechol by potato enzyme diminished as H2O2 concentration increased. By contrast, the rate of oxidation of chlorogenic acid in the presence of H2O2 increased. Bovine catalase destroyed H2O2 and thus ef

Minor components, including principal phenolics and certain enzymes, are distributed within the potato tuber according to patterns that are significant to many practical problems in the growing, handling, and utilization of potatoes. Chlorogenic acid
