“…Various factors, such as the nozzle size, applied voltage, flow rate, and distance of the collection of the polymeric solution that is required to produce the desired size of particles or morphology, must be taken into account [ 95 ]. In the microencapsulation process, an electrospray technique is also used for the fabrication of a wide range of particle sizes [ 96 ]. To overcome the viscosity and surface tension of the polymeric solution, which leads to the distortion of particles at the needle tip, electrostatic forces are applied [ 97 ].…”

The current review investigates the effects of black seed (Nigella sativa) on human health, which is also used to encapsulate and oxidative stable in different food products. In recent decades, many extraction methods, such as cold pressing, supercritical fluid extraction, Soxhlet extraction, hydro distillation (HD) method, microwave-assisted extraction (MAE), ultrasound-assisted extraction, steam distillation, and accelerated solvent extraction (ASE) have been used to extract the oils from black seeds under optimal conditions. Black seed oil contains essential fatty acids, in which the major fatty acids are linoleic, oleic, and palmitic acids. The oxidative stability of black seed oil is very low, due to various environmental conditions or factors (temperature and light) affecting the stability. The oxidative stability of black seed oil has been increased by using encapsulation methods, including nanoprecipitation, ultra-sonication, spray-drying, nanoprecipitation, electrohydrodynamic, atomization, freeze-drying, a electrospray technique, and coaxial electrospraying. Black seed, oil, microcapsules, and their components have been used in various food processing, pharmaceutical, nutraceutical, and cosmetics industries as functional ingredients for multiple purposes. Black seed and oil contain thymoquinone as a major component, which has anti-oxidant, -diabetic, -inflammatory, -cancer, -viral, and -microbial properties, due to its phenolic compounds. Many clinical and experimental studies have indicated that the black seed and their by-products can be used to reduce the risk of cardiovascular diseases, chronic cancer, diabetes, oxidative stress, polycystic ovary syndrome, metabolic disorders, hypertension, asthma, and skin disorders. In this review, we are focusing on black seed oil composition and increasing the stability using different encapsulation methods. It is used in various food products to increase the human nutrition and health properties.

“…Dış kaplama malzemesi; mikrokapsüllerin morfolojik ve yapısal özelliklerini ve buna bağlı işlevsel performanslarını önemli ölçüde etkilemektedir. Bu nedenle gül yağının mikroenkapsülasyonunda jelatin ile yapılan kaplamanın yeterli olamayacağından, ikinci bir kaplama malzemesi olarak kahverengi alglerin hücre duvarlarından ekstrakte edilerek kolaylıkla elde edilebilmesi ve ayrıca biyobozunur, biyouyumlu, antibakteriyel doğal bir polimer olması nedeniyle sodyum aljinat tercih edilmiştir [20].…”

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.

This study aims to produce an active lipase detergent additive dry powder using spray drying. Staphylococcus aureus HA25, growing at a pH range of 5.0–8.5, was isolated from Erzurum gogermis cheese and purified using a three‐phase partitioning technique. Optimal immobilization processing conditions were determined for 0.1% wt/wt chitosan, alginate, and chitosan/alginate concentrations of pure lipase enzyme. Morphological features of the immobilized enzyme structure were determined using scanning electron microscopy (SEM) analysis, and structural characterizations were determined using x‐ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, and thermogravimetric (TG) analysis. The results showed that the natural structure of the lipase was largely restored upon reconstitution of the spray‐dried immobilized lipase structures in water. While the free enzyme removed 52.6% of the oil added to the cotton fabric, the immobilized lipase@alginate enzyme removed ~98% of the oil added to the cotton fabric at the highest rate when used as a detergent additive. It was found that the reusability activity of chitosan@lipase, alginate@lipase, and chitosan/alginate@lipase enzymes remained at 86.4%, 92.8%, and 88.6% of their original activity, respectively. The study suggests that immobilized variations of the lipase enzyme within chitosan, alginate, and chitosan/alginate matrices may serve as a natural, secure, and efficient substitute for conventional chemical detergents, offering a non‐toxic alternative for additive materials.
