“…This is possibly due to the removal of impurities such as betacyanin, red pigment, anthocyanin, and the total phenolic compounds from the peel extract of pectin. 27,28 The wet pectin from papaya had an orange-cream colour, whereas those from the others had a yellowish-white colour (Figure 2b). The drying temperature for all the pectin samples was in the range of 45 to 50 °C, which is considered to be optimum owing to the highest extraction yield obtained.…”

Pectin is widely used as the main polymer in cosmetics, pharmaceuticals, and biomedical applications. The pectin utilization in diverse fields can contribute to fruit waste processing since waste such as fruit peel serves as a pectin source. This study is aimed to analyze the extraction temperature effect on the physicochemical properties of extracted pectin from various tropical fruit peel waste. In this study, we determined the extracted pectin’s physicochemical properties from peel wastes of tropical fruits like papaya, lime, lemon, and dragon fruit using 3% citric acid at 65 and 90°C. A higher pectin yield resulted from a higher extraction temperature of 90oC (8.78 to 27.03 %) than that obtained at 65oC (5.78 to 17.71 %). The spectra of Fourier transform infrared (FT-IR) mainly showed the degradation of pectin, specifically in the cases of papaya, lime, and lemon, indicated by the higher OH peak intensity. All samples extracted were high methoxyl pectin (HM), with degrees of esterification (DE) ranging from 56.98 to 89.63%. Among the fruit peels studied, only the lemon peel pectin extracted at 90°C, with anhydrouronic acid (AUA) content of 77.35%, meets the criteria for food additives and pharmaceutical purposes.

Tujuan penelitian ini adalah menganalisis gugus fungsi dan menentukan kadar total fenol ekstrak air kulit buah naga merah dan buah naga putih. Analisis gugus fungsi ditentukan dengan FTIR. Penetapan kadar total fenol memakai metode Follin Ciocalteu. Hasil penelitian menginformasikan bahwa ekstrak air kulit buah naga merah dan putih mengandung gugus fungsi O-H, C-H, C-O, dan C=C. Ekstrak air kulit buah naga merah dan putih muncul vibrasi yang menunjukkan senyawa fenolik, saponin, dan tanin dari gugus O–H pada bilangan gelombang 3470,09 dan 3471,22 cm-1; senyawa terpenoid dan steroid untuk gugus fungsi C–H alkana pada bilangan gelombang 2921,32 dan 2923,25 cm-1; senyawa terpenoid dan steroid untuk gugus fungsi C=C alkena pada bilangan gelombang 1637,64 dan 1638,60 cm-1; senyawa flavonoid, alkaloid, tanin untuk gugus C–O pada bilangan gelombang 1079,22 dan 1081,15 cm-1; dan senyawa fenolik, flavonoid, tanin, dan saponin untuk gugus C–H aromatik pada bilangan gelombang 699,23 dan 697,30 cm-1. Kadar total fenol pada ekstrak air kulit buah naga merah sebesar 52,99478 + 0,6678 mg/L sedangkan untuk kulit buah naga putih sebesar 78,8739 ± 1,1301 mg/L.

Dragon fruit contains various nutrients and functional values both in the flesh and skin. The skin of dragon fruit contains 30-35% water. It has lots of phenolic compounds and antioxidants, of which the higher amount of antioxidants are in the skin. These compounds are very easily damaged due to the extraction process especially if done incorrectly. This article is written to be a guide in selecting the extraction process in order to preserve the compounds. Based on the review, it is found the modern UAE (Ultrasound Assisted Extraction) process provides better quality than the other various conventional and modern extraction processes. UAE is an extraction process that does not use a heating process in its extraction which can damage the phenolic compounds and antioxidants. The results of the analysis of phenolic compounds using the UAE system have found betacyanin 17.64 mg, phenolic compounds 65.16 mg, flavonoid compounds 195 mg and antioxidants 620 mol. Thus, the recommended treatment to do is to use UAE extraction.
