The increase in new technology and consumer demand for healthy safe food has led to the development of smart packaging help consumers understand conditions real time. incorporation red dragon fruit peel anthocyanin into cassava starch chitosan films was used this study as a color indicator monitor conditions. This film generated using solvent-casting method. mechanical, morphological, physicochemical characterizations were studied, freshness monitoring carried out. results showed that adding...
Abstract A novel indicator film was produced with N‐glutaryl chitosan (ChGA) as a matrix and butterfly pea flower anthocyanin (BPA) dye. The synthesis of ChGA achieved by the reaction (Ch) glutaric anhydride (GA), which resulted in structural alteration Ch, carboxylic groups being present ChGA. ChGA–BPA demonstrated higher sensitivity to changes pH, more compact structure, hydrophilic properties compared Ch‐BPA film. antioxidant antimicrobial activity, well an enhanced biodegradable...
This paper investigates the interaction within a liposome-based drug delivery system in silico. Results confirmed that phospholipids, cholesterol, beta-carotene, and vitamin C liposome structures interact noncovalently. The formation of noncovalent interactions indicates liposomal from phospholipid molecules will not result chemical changes to or any encapsulated within. Noncovalent formed include (i) moderate-strength hydrogen bonds with energies ranging -73.6434 kJ·mol-1 -45.6734 bond...
The abundance of applications alginates in aqueous surroundings created by their interactions with water is a fascinating area research. In this paper, computational analysis was used to evaluate the conformation, hydrogen bond network, and stabilities for putative intermolecular between alginate dimers molecules. Two structural forms (alginic acid, alg, sodium alginate, SA) were evaluated density functional theory (DFT-D3) method at B3LYP basis set 6-31++G** chosen calculating data....
Amylum is one of the polysaccharides developed into biodegradable plastic bags. However, amylum-based plastics are easily damaged due to their low mechanical strength and hydrophilic properties. Cellulose used as a support material in increase reduce water damage. This study investigated molecular interactions between amylum cellulose computationally. The minimum interaction energy was calculated using silico modeling Density Functional Theory (DFT) method. B3LYP function basis set 6-31++g**...
Abstract An experimental and computational study was carried out for encapsulation of vitamin C in sesame, Sesamum indicum L., liposomes. Based on studies, the packing parameter (P) sesame phospholipids found to be 0.64 ± 0.09. This indicates that molecular shape is form truncated cone and, aqueous solution, it self-assembles In liposomes, no chemical interaction observed between phospholipid molecules C. However, medium-strength hydrogen bonds ( E i ) from -87.6 kJ/mol -82.02 with bond...
Banana ripeness is generally determined based on physical attributes, such as skin color; however, it considered subjective because depends individual factors and lighting conditions. In addition, improper handling can cause mechanical damage to the fruit. Intelligent packaging in form of indicator film incorporated with anthocyanins from red dragon fruit peel has been applied for shrimp freshness detection; this low color stability during storage, necessitating addition gambier catechins a...
Minyak jelantah merupakan sisa dari proses menggoreng makanan yang umumnya berasal beragam jenis minyak goreng seperti kelapa dan sawit. Penggunaan berulang dalam penggorengan berpotensi menimbulkan masalah kesehatan lingkungan. Program ini mengeksplorasi peluang mengubah menjadi lilin aromaterapi guna mengurangi dampak negatifnya meningkatkan nilai produk limbah di Lilin memiliki ekstra berupa aroma manfaat aromaterapi. Tim Pengabdian Universitas Katolik Indonesia Atma Jaya telah mengadakan...
A new type of hydrogels based on poly(styrene-alt-maleic anhydride) (PSMA) was prepared via Diels-Alder click chemistry.The formulations consisting tetrazine-functionalized PSMA as a multi-clickable polymer and norbornene-terminated poly(ethylene glycol) (PEG) polymeric cross-linker were used precursors to give ultrafast with controlled structures.The formed within several minutes under physiological condition without any catalyst, their storage modulus (G′) values in the range 0.3-1.7 kPa...
The high application of Poly(styrene-maleic acid) (PSMA) in an aqueous environment, such as biomedical purposes, makes the interaction between PSMA and water molecules interesting to be investigated. This study evaluated conformation, hydrogen bond network, stabilities all possible intermolecular interactions with (PSMA−(H2O)n, n = 1–5). All calculations were executed using density functional theory (DFT) method at B3LYP 6–311G** basis set. energy PSMA–(H2O)5 complex was –56.66 kcal/mol,...
In this study, gold nanoparticles (GNPs) were successfully fabricated via a polymer-templating method and applied for surface-enhanced Raman scattering (SERS) enhancement. The block copolymer, poly(ethylene glycol)-block-poly(styrene-alt-maleic anhydride) (PEG-b-PSM) modified with thiol groups, was used to prepare GNPs. results indicated that the polymer facilitated GNPs form an assembly without aggregation; thus, distance between adjacent could be ideal SERS application. Furthermore, when...
