A comparative study of the nutritional values, volatile compounds, and sensory qualities of pea pastes cooked in iron pot and clay pot

摘要

In the current study, the nutritional values, volatiles compounds, and sensory qualities of pea pastes cooked in iron pot and clay pot were compared. Results showed that the iron pot-cooked pea pastes contained profoundly more iron, total sugar, and starch than the clay pot-cooked ones, and the effects were found related to iron ion by comparing the results between clay pot-cooked pastes with and without iron ion addition. Samples prepared with the two utensils demonstrated similar contents of protein, polyphenol, and tannin, but differed in the composition of some volatile alcohols, alkanes, aldehydes, ketones, esters, and organic acids. The clay pot-cooked samples had higher score of “color,” “mouthfeel,” “taste,” and “overall quality” than the iron pot-cooked pastes. In conclusion, iron pot can allow the production of iron-enriched pea pastes whose sensory qualities are remarkably lower than those of the clay pot-cooked samples but are still in the acceptable range.
