“…The protein content of the jack bean flour used is 32,178%, this protein content had a higher value than the protein content of the jack bean in Susanti et al is 28,6% [14]. The anthocyanin content of the red dragon fruit concentrate used has a level value of 2,933%, this is much lower than the anthocyanin content of the red dragon fruit syrup which is 43,15% [24]. This may be due to the different levels of ripeness of the fruit used or the nutrients that the fruit gets during its growth period.…”

“…Buah naga merah mengandung vitamin C, vitamin B3 (niasin), serat dan betasianin yang lebih tinggi dibandingkan buah naga putih (Prakoso et al, 2017). Pemanfaatan daging maupun kulit buah naga merah sudah banyak dilakukan oleh peneliti-peneliti sebelumnya, diantaranya sebagai pewarna dan pengawet alami pada mie basah (Enjelina et al, 2019), bahan tambahan pada pembuatan permen jelly (Fajriani, 2013) dan es krim (Waladi & Vonny, 2015), fortifikasi sari daging buah naga merah pada yoghurt (Maleta & Kusnadi, 2018). Sebagaimana diketahui buah naga merah tidak dapat disimpan terlalu lama karena kadar airnya yang tinggi yaitu sekitar 82,5 -83 g per 100 gram daging buah (Gunasena et al, 2007).…”
