“…The values of TPC and surface phenolic compound values allowed the calculation of the EE. According to Mahdavi et al [ 13 ] a successful encapsulation method dealing with the high retention of the core materials and minimum amounts of the core on the surface. The EE, which ranged from 68.03 to 76.74%, was strongly influenced by both core:shell and MD:GA ratio.…”

“…The approach used by the researchers was the so-called “one variable at time” method in which it was possible to consider just one variable while the others remain constant. The disadvantages of this method are ignoring factors interactions, the relatively high number of experiments, and time/reagent consuming approach [ 13 ].…”

“…In this field, MD has the advantage of being cheap, having low viscosity at high solid concentration and being able to protect the core material from oxidation. Similarly, gum Arabic (GA), a natural colorless plant heteropolysaccharide, has been commonly used as shell material in spray-drying, due to its interesting emulsifying and rheological properties, and besides its high protection against oxidation [ 13 ].…”

The nutritional quality of animal products is strongly related to their fatty acid content and composition. Nowadays, attention is paid to the possibility of producing healthier foods of animal origin by intervening in animal feed. In this field, the use of condensed tannins as dietary supplements in animal nutrition is becoming popular due to their wide range of biological effects related, among others, to their ability to modulate the rumen biohydrogenation and biofortify, through the improvement of the fatty acids profile, the derivate food products. Unfortunately, tannins are characterized by strong astringency and low bioavailability. These disadvantages could be overcome through the microencapsulation in protective matrices. With this in mind, the optimal conditions for microencapsulation of a polyphenolic extract rich in condensed tannins by spray drying using a blend of maltodextrin (MD) and gum Arabic (GA) as shell material were investigated. For this purpose, after the extract characterization, through spectrophotometer assays and ultra-high-performance liquid chromatography-quadrupole time-of-flight (UHPLC-QTOF) mass spectrometry, a central composite design (CCD) was employed to investigate the combined effects of core:shell and MD:GA ratio on the microencapsulation process. The results obtained were used to develop second-order polynomial regression models on different responses, namely encapsulation yield, encapsulation efficiency, loading capacity, and tannin content. The formulation characterized by a core:shell ratio of 1.5:5 and MD:GA ratio of 4:6 was selected as the optimized one with a loading capacity of 17.67%, encapsulation efficiency of 76.58%, encapsulation yield of 35.69%, and tannin concentration of 14.46 g/100 g. Moreover, in vitro release under varying pH of the optimized formulation was carried out with results that could improve the use of microencapsulated condensed tannins in animal nutrition for the biofortification of derivates.

“…Helichrysum italicum ) in a microcapsule of ethyl cellulose because the major advantage of using microencapsulation technology is its ability to protect the active ingredients from hazardous environments, i.e., oxidization, heat, acidity, alkalinity, moisture, or evaporation [ 15 , 21 , 22 , 23 , 24 , 25 ]. There are many previous reports of essential oil encapsulation and some of them are based on: How to control the size distribution of capsules, establish that the essential oil was entrapped within the microcapsules rather than being adsorbed onto the surface, the influence of weight ratio of core and wall material, control the main variables (the sample-flow transfer rate, drying air-flow, and temperature) to obtain the best powder recovery and oil content [ 14 , 15 , 22 , 23 , 24 , 25 , 26 , 27 ].…”

In this study, microcapsules were prepared by solvent evaporation technique using ethyl cellulose component as wall and essential oil as core material. The synthesis of microcapsules was carried out using different oil masses. The analysis of the microcapsules was carried out using field emission scanning electron microscope (FE-SEM) and UV spectrophotometric analysis using absorption spectrophotometer. The obtained results confirm the regular spherical shape and size of the synthesized microcapsules. The qualitative and quantitative spectrophotometric analysis of the microencapsulated immortelle oil was measured at the wavelength of 265 nm. The calibration diagram was used to calculate the unknown concentrations of the microencapsulated oil. The obtained results confirm the application of the presented method as relevant for the possible determination of microencapsulated oil on textile materials.

Mikroenkapsülasyon, günümüzde gıda, ilaç, tarım, tekstil, kozmetik, biyomedikal gibi endüstrilerde aktif bileşen stabilitesinin ve biyoaktif özelliklerinin korunması için sıklıkla başvurulan, aktif maddelerin etrafını bir ya da birden çok kaplama maddesi ile sarılmasını sağlayan bir teknolojidir. Ülkemiz için ticari öneme sahip olan ve antikanser, antioksidan, antiseptik, hipolipidemik, antidiyabetik, antimikrobiyal ve antibakteriyel özellikleri nedeniyle geniş uygulama alanı bulabilecek gül yağı, oda sıcaklığında hidrokarbon grubu bileşen oranının artmasıyla katılaşmaya başlamakta ve karakteristik özelliklerini kaybetmektedir. Bu nedenle yapılan bu çalışma ile, duvar materyali olarak jelatin ve aljinat kullanılarak, kompleks koaservasyon metodu ile gül yağının mikroenkapsüle edilmesi amaçlanmıştır. Sentez sırasında farklı oranlarda jelatin/aljinat içeren mikrokapsüller (6J/A/5GY, 8J/A/5GY, 10J/A/5GY, 12J/A/5GY) elde edilmiş olup, jelatin/aljinat oranının mikrokapsülleme verimi, % yüzey yağı, % toplam yağ miktarı ve enkapsülasyon etkinliği üzerine etkileri araştırılmıştır. 12J/A/5GY mikrokapsüllerinin %85,5 mikrokapsülleme verimi, 50,1 % toplam yağ, % 88,0 enkapsülasyon etkinliği ile en yüksek özelliklere sahip olduğu gözlemlenmiştir. Mikrokapsüllerin morfolojileri ve oluşumları taramalı elektron mikroskobu (SEM) ile incelenmiş olup, kaplama materyal oranının mikrokapsüllerin oluşumlarında önemli etkiye sahip olduğu tespit edilmiştir. Ayrıca, mikrokapsüllerin termal kararlılıkları diferansiyel termal analiz ve termogravimetrik (DTA-TG) analiz ile incelenmiş olup, mikrokapsüllerin yüksek sıcaklıklarda bile termal kararlılıklarını koruduğunu gözlemlenmiştir. Bu çalışma ile elde edilen sonuçlara göre gül yağı içeren mikrokapsüllerin; parfümeri, kozmetik, sağlık ve tekstil sektöründe önemli kullanım alanları bulabileceği düşünülmektedir.
