Abstract

AbstractN-octyl cinnamic is a compound that has potential as a drug as an antioxidant, anti- inflammatory, but is constrained by the nature of n-octyl cinnamate which is difficult to dissolve in water, causing low bioavailability in the systemic circulation. To overcome this problem, curcumin is formulated in the form of nanoparticles using chitosan polymer, a derivative of chitin which can be obtained from crab and shrimp shell waste. This study aims to synthesize n-octyl cinnamic nanoparticles using a simple coating method using chitosan and sodium alginate and to evaluate the stability of the nanoparticles in vitro. The characterization of nanoparticles that was carried out included adsorption efficiency tests, particle size determination using a Particle Size Analyzer and morphological observations using a Transmission Electron Microscopy (TEM) tool. The antioxidant activity test was carried out to determine the potential of the synthesized compound using DPPH method. The results showed that the nanoparticle formula contained n-octyl cinnamic composition with an adsorption % of 91.02%. The particle size is 68.1 nm based on particle size analyzer testing with an average size of 519.6 . The morphological observations showed that the particles were spherical in shape with an uneven surface. The n-octyl cyanamate/Alginate/Chitosan nanoparticles have antioxidant activity with an EC50 value of 31.57 ppm. This shows that n-octyl siamate/alginate/chitosan nanoparticles have the potential to be developed as an antioxidant.Keywords: Nanoparticle, Antioxidant, n-Octyl cyanamate/Alginate/chitosan, Synthesis

Abstract

Encapsulating lipophilic curcumin improves digestibility and bioavailability. Loading efficiency and droplet size are crucial when encapsulating curcumin into emulsion-based delivery systems. Since the thickness of the emulsifier layer is comparable to that of the radius of the oil droplet, one can deduce that the emulsifier layer is the primary component of the droplet's overall composition. Because the oil droplet radius matches the emulsifier layer thickness. Nanoemulsion (NE) is ideal for encapsulating, protecting, and delivering lipophilic nutraceuticals for food and food-related applications. Conventional emulsion has several-micrometer droplets. Chitosan-coated NE can deliver lipophilic bioactive substances. This is because it will better protect the core material. Phase separation was observed in the NE emulsion sample after it had been stored for three months, in contrast to the CNE emulsion sample. Multilayered emulsion is a multistep procedure that consists of emulsion droplets electrostatically stabilized by layers of alternatively charged emulsifiers and chitosan. The large surface area of nanoemulsions allows the acceleration of the chemical reactions occurring at the oil-water interface such as hydrolysis by lipases. There was a study that investigated the effect of nanosystems' interfacial composition using multilayer chitosan on the stability of curcumin during in vitro digestion, on lipids digestibility, cumin bioaccessibility and antioxidant activity, using a dynamic GI system.

Abstract

Inefficient textile waste processing can pollute the environment and endanger the health of the adjacent community. Methyl orange is one of the most extensively used dyes in the textile industry. Various physical, chemical, and biological processes have been utilized to dispose of methyl orange residue. One of the basics is the adsorption method. This research was conducted to determine the adsorption capacity of activated rice husk powder as an adsorbent to reduce methyl orange content. The activation of rice husk powder also influences the decrease in methyl orange concentrations. The variables used are mass, contact time, and pH, and the adsorption isotherm model is determined. The results demonstrated a decrease in methyl orange concentration from the optimal mass variable of 8 grams, contact time of 60 minutes, and pH of 7, with an adsorption capacity of up to 89%. The adsorption isotherm equation is compatible with the Langmuir equation because the R2 value of 0.926% is closer to 1 than the Freundlich equation.Keywords: Adsorption, Activation, Adsorption Isotherm, Methyl Orange, Rice Husk Powder.
