“…The entrapment efficiencies (EE) of both SD and HD preparations were high in all cases, reaching values above 95% for CH and PP samples regardless of the drying procedure used (Table 1). These values were higher than those reported, for instance, by Goula and Adamopoulos 20 for spray-dried skimmed milk powder microcapsules containing a pomegranate seed extract with an average particle size of ≈13 µm (80%) or by Jayanudin et al 23 for red ginger oleoresin-chitosan-corn oil emulsions dried at 70°C (79.5-82.5%). In general, comparisons with the reported literature are quite difficult since both materials and encapsulating conditions differ considerably from each other.…”

Zingiber officinale var. rubrum (red ginger) is widely used in traditional medicine in Asia. Unlike other gingers, it is not used as a spice in cuisines. To date, a total of 169 chemical constituents have been reported from red ginger. The constituents include vanilloids, monoterpenes, sesquiterpenes, diterpenes, flavonoids, amino acids, etc. Red ginger has many therapeutic roles in various diseases, including inflammatory diseases, vomiting, rubella, atherosclerosis, tuberculosis, growth disorders, and cancer. Scientific evidence suggests that red ginger exhibits immunomodulatory, antihypertensive, antihyperlipidemic, antihyperuricemic, antimicrobial, and cytotoxic activities. These biological activities are the underlying causes of red ginger’s therapeutic benefits. In addition, there have been few reports on adverse side effects of red ginger. This review aims to provide insights in terms the bioactive constituents and their biosynthesis, biological activities, molecular mechanisms, pharmacokinetics, and qualitative and quantitative analysis of red ginger.

“…Penggunaan kitosan yang ditaut silang dengan glutaraldehida juga sudah dilaporkan oleh Jayanudin et al, (2019a), tetapi untuk membuat mikrokapsul oleoresin jahe merah yang digunakan sebagai antioksidan. Kelebihan lain dari penggunaan kitosan karena bersifat biodegradabel dan biokompatibel.…”

“…Mikrokapsul pupuk NPK yang dibuat dari reaksi taut silang antara larutan kitosan dengan 5% (v/v) konsentrasi larutan glutaraldehida Gambar 5 menunjukkan bahwa perubahan konsentrasi larutan kitosan sebagai penyalut mikrokapsul pupuk NPK berpengaruh pada jumlah pupuk NPK yang release. Peningkatan konsentrasi larutan kitosan membuat viskositasnya semakin meningkat dan membuat dinding mikrokapsul menjadi lebih padat yang memungkinkan pupuk NPK yang release menjadi lebih rendah (Jayanudin, 2019a;Dini et al, 2003).…”

Pelepasan terkendali pupuk NPK bertujuan untuk meningkatkan efisiensi penggunaan unsur hara tanaman dan juga untuk mengurangi pencemaran lingkungan. Penelitian ini bertujuan untuk menentukan pengaruh konsentrasi larutan kitosan dan glutaraldehida terhadap yield dan daya serap mikrokapsul pupuk NPK. Tujuan lain adalah menentukan karakterisasi dan analisis release pupuk NPK dari mikrokapsul dan juga menghitung kinetika release. Mikrokapsul pupuk NPK dipreparasi dengan mencampurkan pupuk NPK cair ke dalam larutan kitosan, kemudian campuran tersebutkan diteteskan ke dalam larutan glutaraldehida sambil diaduk. Mikrokapsul pupuk NPK yang terbentuk dicuci menggunakan petroleum eter dilanjutkan dengan heksana dan dikeringkan. Hasil penelitian menunjukkan bahwa peningkatan konsentrasi larutan kitosan dan glutaraldehida menghasilkan peningkatan yield, menurunkan daya serap air, dan menurunkan pupuk NPK yang release dari mikrokapsul pupuk NPK. Model kinetika release yang sesuai berdasarkan tingginya nilai R2 adalah model order satu dan model Higuchi didapat dari mikrokapsul pupuk NPK yang dipreparasi dengan 1% (b/v) larutan kitosan dan 5% (v/v) larutan glutaraldehida. <div> </div><div>Encapsulation and Characterization of Controlled Release of NPK Fertilizer Using Glutaraldehyde-Crosslinked Chitosan. Controlled release NPK fertilizer aims to improve the nutrient use efficiency (NUE) of plants and also to reduce environmental pollution. This study aims to determine the effect of the concentration of chitosan and glutaraldehyde solutions on the yield and absorptive ability of NPK fertilizer microcapsules. Another objective was to determine the characterization and analysis of NPK fertilizer releases from microcapsules and also to calculate the release kinetics. NPK fertilizer microcapsules were prepared by mixing liquid NPK fertilizer into a chitosan solution, and then the mixture was dripped into a glutaraldehyde solution while stirring. NPK fertilizer microcapsules formed were washed using petroleum ether, followed by hexane and dried. The results showed that an increase inthe concentration of chitosan and glutaraldehyde solutions resulted in an increase in yield, decreased water absorbency, and lower NPK fertilizer released from microcapsules. The appropriate release kinetics models based on the higher R2 value were the first-order model and the Higuchi model obtained from microcapsules of NPK fertilizer that was prepared with 1% (w/v) chitosan solution and 5% (v/v) glutaraldehyde solution.</div>
