Bacterial cellulose (BC) is a polymer obtained by fermentation with microorganism of different genera. Recently, new producer species have been discovered, which require identification the most important variables affecting production. In this work, influence carbon sources in BC production novel low pH-resistant strain Komagataeibacter medellinensis was established. The Hestrin-Schramm culture medium used as reference and compared to other media comprising glucose, fructose, sucrose, at...
Cellulose crystallinity can be described according to the crystal size and index (CI). In this research, using Fourier-transform infrared spectroscopy (FTIR) X-ray diffraction (XRD) methods, we studied of three different types cellulose: banana rachis (BR), commercial cellulose (CS), bacterial (BC). For each type cellulose, analyzed crystallization grades. These variations were obtained milling conditions: 6.5 h, 10 min, unmilled (films). We developed a code in MATLAB software perform...
Edible coatings and films are appealing strategies for the postharvest management of blueberries. In current work, alginate alginate/cellulose nanofibril (CNF) edible crosslinked with calcium chloride were developed application on Andean blueberry (a promissory wild blueberry). Cocoa by-products valorized through isolation their CNFs, these incorporated in coatings. coating formulations based blends (2% w/v), CNFs (0%, 0.1%, or 0.3%), glycerol, water. addition, stand-alone prepared, light...
The agroindustry generates substantial quantities of byproducts, particularly in coffee production, which yields significant waste, most notably spent grounds (SCGs). This study explores the potential SCGs as a versatile resource for applications both food and nonfood sectors. A comprehensive chemical analysis revealed that consist 30.2 wt.% cellulose, 25 hemicellulose, 12 lignin. Morphological characterization was performed using field emission scanning electron microscopy (FESEM)....
Emulsion stabilization is a broad and relevant field with applications in oil, polymer food industries. In recent years, the use of solid particles to stabilize emulsions or Pickering have been studied for their kinetic physical properties. Nanomaterials derived from natural sources are an interesting alternative this application. Cellulose nanofibrils (CNFs) widely explored as emulsifier potential applications, however, some cases presence surfactants unavoidable, literature devoid...
Color is an important characteristic of food products. This related to consumer acceptability. To use the entire rhizome Curcuma longa (CL) as a colorant, novel gel alike stable suspension (CLS) was previously developed using cellulose nanofibers (CNFs). Therefore, present study conducted evaluate CLS color additive on stirred yogurt. Three concentrations were studied (0.1, 0.125, and 0.15 wt. %) compared yogurt without CLS. The obtained yogurts characterized through determination pH,...
Cellulose nanofibrils from the banana rachis are a good alternative as packaging materials, food packaging, stabilizing agents, and functional ingredients. To address potential effects of ingested cellulose (BR-CNFs), their toxicity in vitro vivo was evaluated using Caco-2 intestinal cells mice, respectively. The results showed that BR-CNFs did not cause cytotoxic at concentrations on cells. In addition to cytotoxicity tests, genotoxicity assays comet assay indicated no DNA damage CNFs...
Abstract Curcuma longa is a rhizome used for the extraction of curcumin, yellow colorant that only represents 3 wt% dried rhizome. To increase possibility using entire as food colorant, in present investigation, effect ultra‐fine friction grinding ( supermasscolloider ) to obtain turmeric suspensions was evaluated. achieve this goal, two distances between stones or Gap were evaluated (G –1 and –1.5), obtained characterized by infrared spectroscopy through determination curcumin content,...
