Abstract

Enkapsulasi asam klorogenat ekstrak umbi yakon merupakan salah satu cara untuk melindungi senyawa-senyawa aktif menggunakan paduan polimer alam kappa karagenan-locust bean gum dengan penggunaan ion K+ sebagai pengikat matriks melalui metode gelasi ionik. Pada penelitian ini dilakukan pembentukan gel dari kappa karagenan dan locust bean gum dengan bantuan larutan KCl. Tujuan penelitian ini adalah untuk mengetahui pengaruh konsentrasi larutan KCl pada pembentukan gel serta efektifitas enkapsulasinya. Bertambahnya konsentrasi larutan KCl juga membuat gel menjadi lebih kaku. Hasil uji menunjukkan bahwa penggunaan larutan KCl 0,3M dapat menghasilkan nilai efisiensi enkapsulasi sebesar 79,44%. Kemiripan spektra IR antara gel kappa karagenan-locust bean gum, asam klorogenat murni dan asam klorogenat terenkapsulasi menunjukkan bahwa asam klorogenat hanya terperangkap secara fisik dalam matriks kappa karagenan-locust bean gum dan perubahan spektra karakteristik dari kappa karagenan dari 1018 cm-1 menjadi 1023,62 cm-1 pada sampel hasil enkapsulasi menunjukkan adanya interaksi antara gugus OH dari locust bean gum dan kappa karagenan. Kata kunci: asam klorogenat; enkapsulasi; kappa karagenan, locust bean gum, Yakon The encapsulation of chlorogenic acid of yacon tuber extract is one way to protect the active compounds using naturals polymers kappa carrageenan-locust bean gum with K+ ions as a matrix binder through the ionic gelation method. This process was carried out by forming a gel from kappa carrageenan and locust bean gum with the help of KCl solution. This encapsulation process has purposes to determine the effect of the concentration of KCl solution on gel formation and the effectiveness of its encapsulation. The test results indicated that the use of 0.3M KCl solution resulted in an encapsulation efficiency value of 79.44%. The bonding between the two polymers and the K+ cation was thought to result in a higher encapsulation effectiveness. The similarity of IR spectra among kappa carrageenan-locust bean gum gel, pure chlorogenic acid and encapsulated chlorogenic acid showed that chlorogenic acid was only trapped physically in the kappa carrageenan-locust bean gum matrix and the shift of kappa carrageenan peak from 1018 cm-1 to 1023,62 cm-1 of the encapsulated sample had shown an interaction between OH groups from locust bean gum and kappa carrageenan.

KCL浓度对雪莲根提取物绿原酸包封率的影响
叶绿素提取物提取物是利用kappa karxan -locust bean合金保护活性化合物的一种方法,该化合物使用K+离子+酶通过离子离子方法将矩阵结合起来。这项研究是在KCl溶液的帮助下构建了kappa kar代理商和locust bean gum凝胶。本研究的目的是确定KCl溶液浓度对凝胶形成及其有效性的影响。KCl溶液浓度的增加也使凝胶更强。测试结果表明,使用KCl 0.3m溶液可以产生79.44%的凝聚力值。凝胶kappa karagenan-locust bean之间的IR光谱相似性口香糖,酸klorogenat纯洁和klorogenat terenkapsulasi表明klorogenat酸只是被困身体里面kappa karagenan-locust bean口香糖和光谱变化特征矩阵从卡帕karagenan 1018 cm-1成为1023.62在enkapsulasi结果显示样本中cm-1星团之间的互动从蝗虫bean口香糖和kappa karagenan哦。关键词:盐酸;enkapsulasi;kappa karagenan, locust bean, Yakon用博物学家kappa carrageenst -locust bean与K+ ions一起矩阵的电离层方法来保护活性分子acid。在KCl解决方案的帮助下,这个过程被kappa carrageenan和locust bean引用了。这种抑制过程的目的是确定KCl溶液在凝胶形成和其抑制效果方面的作用。仅用0.3米的三分之四作为权宜之计被建议的3.3米的结果的结果,价格是79。44%。两种聚合物和K+方正之间的结合是考虑考虑提高效率。卡帕之similarity IR光谱》carrageenan-locust bean口香糖,pure chlorogenic酸凝胶和细胞因子chlorogenic酸那里那个chlorogenic酸只困住的《卡帕carrageenan-locust bean口香糖矩阵和shift键》1018 carrageenan峰从cm-1到1023.62 cm-1》,浓缩展示了样本的interaction哦蝗虫集团从bean口香糖和kappa carrageenan之间。基调:氯乙酸;encapsulation;kappa carrageenan, locust bean, Yacon
