| description |
Sweetpotato(Impomeabatatas) or locally known as ‘keledek’in Malaysia, is one of the
popularcrops grown by small farmers for the fresh market. Sweet potato is a rich crop
with carbohydrates, carotenoidsand pro-Vitamin A.Carotenoids are antioxidants with
pharmaceutical potential and have attracted the interest ofresearchers from diverse
fields including, biochemistry, biology, food science and technology, medicine,
pharmacy, and nutrition for more than a century.Malaysian climate is suitable for sweet
potato growingandthere are 10 popular sweet potato variety recommended to grown in
Malaysia. This study was conducted to identify which type of Malaysian sweet potato
ttuber is the best in its content of carotenoids. Moreover, this study was carried out to
evaluate and compared the total carotenoid content (tot. carot. cont.) and their stability
in themost popular, available and cheapest variety of Malaysian sweet potato tuber over
different postharvest storage time of four types of fresh flesh of sweet potato (SP) from
KL, Malaysian local markets. Totalcarotenoid content were identified by
spectrophotometric method for the powder of freeze dried of flesh for; orange, yellow,
purple and white sweet potatofresh samples. The results of this study showed that the
orange sweet potato flour showed the highest value in total carotenoid content for the
whole four weeks of storage comparing to the other types of sweet potato followed by
yellow, purple and white sweet potato for four weeks storage. Total carotenoid content
ranged from 111.18 µg/g dry weight (DW)in white sweet potatoWSP to 382.217
µg/gdry weight (DW)in orange sweet potato (OSP) in the first week of storage, while
the fourth week of storage shows that total carotenoid content ranged from 42.903 µg/g
DW in white sweet potato WSP to 233.182 µg/g DWin orange sweet potato OSP.This
study showed that the local varieties of sweet potatoes differ among themselves with
respect to the content of carotenoids in tubers before and after storage. The postharvest
storage time was influenced by the quantity and stability of those four types of fresh
flesh of sweet potatoes nutritional values. |
