RETENTION OF VITAMIN C, IRON, AND β‐CAROTENE IN VEGETABLES PREPARED USING DIFFERENT COOKING METHODS1

Abstract: The true retention of vitamin C, iron, and &carotene in five vegetables cooked by household microwave-steaming, stirgrying with oil, stir-frying with water, and boiling to equal degrees of overall acceptability were compared. Vegetables prepared by microwave-steaming and stir-frying with oil had significantly higher (means of 1.31 -to 1.83 fold) vitamin C retention values than those which were boiled. lron retention was significantly higher (means of 1. I7-to 1.34-fold) in four of jive vegetables cooked by mic… Show more

“…Cooking decreased the vitamin C content of potatoes by about 30% and keeping potatoes hot for 1 h after cooking decreased vitamin C content by a further 10% (Hagg et al, 1998). Vegetables prepared by microwave-steaming and stir-frying with oil had significantly higher (1.3-1.8-fold) vitamin C retention values than those that were boiled (Masrizal et al, 1997). Vegetables reheated after 1 day of chilled storage had greater losses of vitamin C compared to those held at 72°C for 30 min, but better vitamin C retention than vegetables held hot for 2 h. If warm-holding is restricted to less than 90 min vitamin retention in vegetables is likely to be higher in a cook/hot-hold foodservice than with a cook/chill system (Williams et al, 1995).…”

“…Processing methods such as microwave-steaming and stir-frying with oil have been reported to offer greater retention of β-carotene in some vegetables than when boiled or stir-fried with water (Masrizal et al, 1997). On the other hand, eating cooked and pureed spinach leads to higher plasma total β-carotene concentrations, compared to raw consumption (Rock et al, 1998).…”

“…En relación a la cocción por microondas, los resultados del presente estudio son semejantes con los encontrados por Campbell et al (1958), Tannenbaum (1979), Marrizal et al (1997), Howard et al (1999), Kaur y Kapoor (2001) y Ramesh et al (2002), que observaron que la retención de vitamina C fue mayor en los alimentos cocidos por microondas que en los cocidos a ebullición.…”

Gester (1989) afirma que, debido a que la cocción utilizando microondas exige menor tiempo para la preparación del alimento, éste es expuesto al calor por un En relación a la coliflor, se observó una diferencia significativa (p≤0,05) entre las muestras ultracongeladas y en fresco solamente con respecto al color cuando fueron sometidas a ebullición, siendo la coliflor en fresco la preferida.…”
