“…Besarnya aktivitas antioksidan berbanding terbalik dengan nilai IC50, artinya semakin tinggi aktivitas antioksidan maka semakin rendah nilai IC50 (Budilaksono et al, 2014;Nurullita & Irawati, 2022;Palimbong et al, 2020;Permadi et al, 2022;S. S. Putri et al, 2020;Safitri & Herdyastuti, 2021;Utari et al, 2017). Waktu ekstraksi yang lama dapat mempengaruhi kadar antioksidan tersebut.…”

Radikal bebas dapat melemahkan fungsi membran sel dan retikulum endoplasma serta menghancurkan sel pada tingkat DNA molekuler. Tubuh manusia membutuhkan antioksidan untuk menstabilkan jumlah radikal bebas dalam tubuh. Antioksidan yang alami terdapat pada tumbuhan diantaranya vitamin, fenol, flavonoid dan karetonoid. Kayu secang termasuk tanaman herbal yang bersifat antioksidan. Senyawa antioksidan yang terkandung pada kayu secang berupa senyawa fenolik,resorsinin, brasilein, asam galat, flavonoid, saponin, terpanoid dan tanin. Metode yang digunakan adalah studi pustaka yang dikaji secara saru persatu, setelah itu jurnal yang diperoleh dikumpulkan dan informasinya disusun dengan cara merangkum isi jurnal yang dijadikan sumber. Dari hasil olahan data, kayu secang memiliki aktivitas antioksidan yang dapat dilihat dari uji In Vitro dengan nilai IC50 dan uji In Vivo pada tikus. Kayu secang digunakan sebagai bahan sediaan kosmetik dapat berupa essence dan hair tonic. Selain itu, juga digunakan sebagai bahan dalam pembuatan minuman dan makanan karena kayu secang memiliki antioksidan yang tinggi.

“…This vibration results in friction between mass particles, which then generates heat [33]. Increasing the temperature of the ultrasonicator can increase the antioxidant activity of red ginger because temperature can increase the phenolic compounds that act as antioxidants [34]. The formation of phenolic compounds takes place at a temperature of about 60 ºC [35].…”

“…The higher the heating temperature, the higher the PPO (polyphenol oxidase) enzyme inactivation process, so that the degradation of phenol is lower. In addition, heating causes the release of antioxidant components as a result of damage to cell walls due to heat [34]. However, if the heating temperature is too high, it can damage the active substance of red ginger.…”

Nanotechnology has developed in various industrial fields. This encourages innovation in the use of additives such as antioxidants, dyes, flavors, and other active ingredients that can be modified in the form of nanoemulsions. Red ginger contains oleoresin, which has thick properties to form a paste. These properties make oleoresin difficult to mix with food, disperse, hydrophobic and susceptible to the effects of heat and light. One solution to overcome this problem is to convert oleoresin into a nanoemulsion so that it has high solubility, is stable, good bioavailability, and improves sensory properties. One technique for making nanoemulsions is ultrasonication. The high-intensity ultrasonication effect can cause the movement of the oil phase into the liquid phase in the form of droplets, thereby increasing the pressure in the liquid and resulting in the breakdown of the oil droplets into smaller sizes. The purpose of this research was to determine the effect of ultrasonication on some chemical properties of the red ginger oleoresin nanoemulsion bioactive compounds, which includes antioxidant activity, total phenol, gingerol content, and droplet microstructure. The study used a completely randomized design with four treatments based on sonication time. Data from the test results were analyzed using analysis of variance (ANOVA) and Tukey's advanced test. Based on the results of the analysis, it was found that ultrasonication had effect on the red ginger oleoresin nanoemulsion biactive compounds. The best treatment is 90 min of sonication. The antioxidant activity (IC50) was 11.45±3.48 ppm, the total phenolic content was 3342.74±283.00 mg GAE/g, and the gingerol content was 0.33 %. The nanoemulsion droplet microstructure complies with the standard; that is, the particles are in the form of small spheres, like balls, and there are no visible holes or cracks on the surface of the particles. HIGHLIGHTS Red ginger contains higher oleoresin than other types of ginger Oleoresin is in the form of a viscous paste, so it is hydrophobic Application of nanoemulsion to oleoresin can increase solubility and bioavailability One of the methods for making nanoemulsions is using ultrasonication The novelty in this research is the manufacture of red ginger oleoresin nanoemulsion using the ultrasonication method to increase the content of bioactive compounds such as antioxidant activity, total phenolic content, and gingerol GRAPHICAL ABSTRACT
