Pumpkin is rich in nutrients, low fat, provide little energy and inexpensive. It is benefit to increase the nutritional value of instant noodles. Therefore, the objective of this research was to study the effect of pumpkin powder (PP) on qualities of instant noodle. PP was added as part of instant noodle at 0, 5, 10, 15 and 20% of the whole mixture basis. The results showed instant noodle without PP had highest water absorption rate, 71.97% (p 0.05). Instant noodles tended to increase cooking loss when increasing the PP. The addition of PP had effect on product color, L* value decrease while a* and b* values increased (p 0.05). The ash and beta-carotene content of PP instant noodles were significantly higher than control (p 0.05). The sensory evaluation showed that the instant noodles substitute with 10% PP had higher score than the others (p 0.05); color, flavor, taste, texture and overall acceptance were 8.77, 8.23, 8.73, 8.33, 8.33 and 8.76, respectively.
This research aimed to develop herbal tea from agricultural by-product such as mango peel. The study was conducted using a 3x3 Factorial in completely randomized design. Two factors were investigated; the kneading time of mango peel at 10, 20 and 30 minutes and the fermentation time of mango peel at 15, 30 and 45 minutes. The result showed that total phenolic content and antioxidant activity of the unripe mango peel were 8.48 mg/g and 18.34%, respectively. And those contents were significantly higher than that ripen mango (p ≤ 0.05). The kneading and fermentation time were affected on total phenolic content and antioxidant activity of the peel. Mango peel kneaded for 20 minutes had 20.83 -28.50% antioxidant activity which significantly higher than that kneaded for 10 and 30 minutes (p ≤ 0.05). And mango peel fermented for 15 minutes had 21.96 -23.01 mg/g total phenolic compounds that significantly higher than fermentation time at 30 and 45 minutes (p ≤ 0.05). Sensory evaluation showed that the score of color, flavor and taste of tea from mango peel kneaded and fermented for 10 and 15 minutes, respectively significantly higher than other kneading and fermentation times (p ≤ 0.05)..
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
