“…Emulsion stability was assessed by visual observation and monitored by taking photos for a storage period of at least one month, at 4 • C. Moreover, accelerated stability tests against gravitational separation were also conducted, by centrifuging the emulsions at 3500 rpm for 10 and 20 min, which are considered equivalent to a gravitational acceleration field applied for around 6 and 12 months, respectively [23]. The effects on the stability of the Pickering emulsions of pH over storage were investigated through microstructure observation and rheological analysis.…”

This work aimed at studying the stabilization of O/W Pickering emulsions using nanosized cellulosic material, produced from raw cellulose or tomato pomace through different mechanical treatments, such as ball milling (BM) and high-pressure homogenization (HPH). The cellulose nanofibrils obtained via HPH, which exhibited longer fibers with higher flexibility than those obtained via ball milling, are characterized by lower interfacial tension values and higher viscosity, as well as better emulsion stabilization capability. Emulsion stability tests, carried out at 4 °C for 28 d or under centrifugation at different pH values (2.0, 7.0, and 12.0), revealed that HPH-treated cellulose limited the occurrence of coalescence phenomena and significantly slowed down gravitational separation in comparison with BM-treated cellulose. HPH-treated cellulose was responsible for the formation of a 3D network structure in the continuous phase, entrapping the oil droplets also due to the affinity with the cellulose nanofibrils, whereas BM-treated cellulose produced fibers with a more compact structure, which did adequately cover the oil droplets. HPH-treated tomato pomace gave similar results in terms of particle morphology and interfacial tension, and slightly lower emulsion stabilization capability than HPH-treated cellulose, suggesting that the used mechanical disruption process does not require cellulose isolation for its efficient defibrillation.

Makromolekul hidrokoloid dinilai mampu menstabilkan emulsi ganda. Penelitian ini bertujuan untuk membuat formulasi emulsi ganda air dalam minyak dalam air (A/M/A) dengan menggunakan natrium karboksimetil selulosa (CMC Na) sebagai emulgator fase air eksternal. Emulsi primer air dalam minyak (A/M) dibuat dengan parafin cair sebagai fase minyak dan mengevaluasi pengaruh konsentrasi emulgator span 80, yaitu 5, 10, 15, dan 20%, terhadap mikroskopi ukuran droplet, viskositas, dan stabilitas emulsi A/M setelah uji heati4ng-cooling cycle. Span 80 dengan konsentrasi 15% menghasilkan karakteristik emulsi primer A/M yang paling baik. Emulsifikasi emulsi primer A/M ke dalam fase air eksternal yang mengandung CMC Na menghasilkan emulsi ganda A/M/A. Peningkatan konsentrasi CMC Na dari 1, 2, dan 3% menghasilkan peningkatan viskositas emulsi ganda secara signifikan. Mikroskopi visual droplet minyak menunjukkan rentang ukuran droplet minyak yang relatif besar pada semua emulsi ganda A/M/A. Pelepasan model zat warna larut air (Ponceau 4R) dari semua emulsi ganda A/M/A sangat kecil (0,06-0,09%) setelah 6 jam pengujian yang mengindikasikan potensi penggunaan emulsi ganda ini sebagai sistem penghantaran lepas lambat. Emulsi ganda A/M/A pada semua konsentrasi CMC Na tidak memisah setelah uji stabilitas dengan metode heating-cooling cycle.

“…The starting sample was transferred into the centrifugation tubes in order to be separated by a centrifugal force (Tehnica LC-320) at a speed of 3500 rpm for 20 minutes at a room temperature (Restu et al, 2015). The supernatant was separated from sediment and was used for the purpose of further analysis.…”

Sugar beet molasses represents the most important by-product in the sugar beet industry which can be valorised through various methods due to very valuable composition. Standard beet molasses composition consists of sugar, nonsugar components and water. Furthermore, beet molasses normally contains betaine in the range from 3 to 8%/DM. Betaine is an important nonsugar component which is not eliminated during the production of sugar, so it accumulates in the molasses and could be obtained through separation process on an industrial chromatographic columns. The main objective of this research was to increase betaine content in betaine fractions and lower other impurities by applying different pretreatments before final separation process. Samples composition was characterized by using the HPLC technique and the quantification was performed by applying external standard method with betaine as a standard. Separation techniques used in this research were: (I) separation method without pretreatment (II) separation with preceded acidification (samples pH value adjustment) and (III) separation with alcohol fermentation as previous treatment. Betaine content in the starting sample was 62.76%/DM. The highest increase in betaine content was achieved by using separation method without pretreatment having final betaine content of 85.16%/DM. By using acidification as pretreatment before centrifugation the level of betaine was increased up to 67.68%/DM, whereas implementing the alcohol fermentation before centrifugation showed no significant differences compared to the starting sample.
