TB122: Comparison of Alpha- and Beta-Carotene Content of Supermarket vs Roadside Stand Produce in Maine
A study was conducted to determine the alpha- and beta-carotene content of supermarket vs roadside stand produce using high-performance liquid chromatography (HPLC). The fruits and vegetables were obtained from a major local supermarket chain and three roadside stands in Dixmont, Etna and Charleston, ME. Thirteen vegetables and one fruit were sampled during a ten-week period between July and September of 1985. Significant differences at the 0.05 level were observed between supermarket and roadside stand produce for only Swiss chard and green peppers with roadside stands having higher beta-carotene levels in both instances. Alpha-carotene was shown to be nonsignificant among sources at the 0.05 level in all cases.https://digitalcommons.library.umaine.edu/aes_techbulletin/1082/thumbnail.jp
