Günümüzde; hastalıkların önlenmesinde ve tedavisinde doğal yollarla alınan birtakım gıdaların etkili olduğunun bilimsel olarak ispatlanması, tüketicilerin bu gıdalara olan ilgisini ve bu gıdaların önemini arttırmıştır. Yapılan bilimsel çalışmaların sonuçları tüketicileri beslenme alışkanlıkları üzerinde düşünmeye ve düzenleme yapmaya itmiş ve yaygın olarak kullanılan sentetik katkı maddeleri hakkındaki düşüncelerini olumsuz etkileyerek doğal bitkisel kaynaklara yönlendirmiştir. Bu gelişmelerle birlikte, bitkilerden doğal antioksidanların elde edilip, geliştirilip ve çeşitlendirilmesi üzerine yapılan araştırmalar da hız kazanarak devam etmiş ve tıbbi ve aromatik bitkiler ile baharatlar, araştırmaların odak noktası haline gelmiştir. Sıvı baharat olarak bilinen oleoresinler, sahip oldukları fizyolojik aktiviteleri sayesinde, bazı tip kanserleri, kardiyovasküler hastalıkları ve yaşlanmayı önleyici etki göstermekte, bağışıklık sistemini güçlendirmekte, kolesterolü, tansiyonu ve kan şekerini düşürücü etki göstermektedir. Yapılan çalışmada ham ürüne göre üstünlükleri olan, fenolik ve yağ asitlerince konsantre edilmiş formda, hem gıda katkıları hem de fonksiyonel ürün olarak çeşitli amaçlarla kullanımları mümkün olan keten tohumu ve zencefil oleoresinleri elde edilmiş ve elde edilmesinde kullanılan solvent ekstraksiyonu koşulları optimize edilmiştir. Bu amaçla deney paremetrelerine göre üç faktör-üç seviye Box-Behnken tepki yüzey deneme deseni oluşturularak ekstraksiyon işlemi gerçekleştirilmiştir. Ekstraksiyon sıcaklığı, ekstraksiyon süresi ve örnek/çözücü oranı değişken parametre olarak belirlenmiştir. Bu değişken parametrelerin ekstraksiyon verimi, toplam fenolik madde miktarı ve radikal süpürücü güçleri üzerine etkisi incelenmiştir. Bu etkilerin değerlendirilmesinde ise; Design-Expert® yazılım programı kullanılmıştır. Zencefilden toplam fenolik miktarı, antiradikal aktivitesi ve ekstraksiyon verimi yüksek olan oleoresin elde edilmesinde; örnek çözücü oranı 1/40, sıcaklık 42,5°C ve ekstraksiyon süresi 22 dakika olarak optimize edilmiştir. Keten tohumundan elde edilen oleoresin için program cevaplarının maksimum değerde olduğu koşullar; örnek çözücü oranı 1/35, sıcaklık 41,3°C ve ekstraksiyon süresi 27 dakika olarak optimize edilmiştir.
Today, scientific proof of the effectiveness of certain foods taken naturally in the prevention and treatment of diseases has increased consumer interest in these foods and the importance of these foods. The results of the scientific studies have pushed consumers to think and regulate their eating habits and have directed them to natural plant resources by negatively influencing their thoughts about the commonly used synthetic additives. With these developments, the research on the obtaining, development and diversification of natural antioxidants from plants has also continued to gain speed and medicinal and aromatic plants and spices have become the focus of research. The oleoresins known as liquid spices, thanks to their physiological activities, have a preventive effect on certain types of cancers, cardiovascular diseases and aging, strengthening the immune system, having a reductive effect on cholesterol, blood pressure and blood sugar. The study, which has advantages over the raw product, in the form concentrated by phenolic and fatty acids, has been achieved and optimized the conditions of solvent extraction used in the obtaining, which can be used for various purposes as both food additives and functional products. For this purpose, according to the trial parametrics, the extract process was carried out by creating a surface trial pattern of three factors-three levels Box-Behnken reaction. The extraction temperature, extraction time and sample/solver ratio are determined as variable parameters.The effect of these variable parameters on the extraction efficiency, the total amount of the phenolic substance and the radical dusting forces has been studied.In the assessment of these effects, the Design-Expert software program has been used.®In obtaining oleoresin with the total phenolic amount, antiradical activity and high extraction efficiency from zinc, the sample solvent ratio is optimized to 1/40, the temperature is 42.5°C and the extraction time is 22 minutes.The conditions in which the program answers are at the maximum value for oleoresin obtained from the chain seed; the sample solvent ratio is optimized to 1/35, the temperature is 41.3°C and the extraction time is 27 minutes.
Today, scientific proof that certain foods taken by natural means are effective in the prevention and treatment of diseases has increased consumers ' interest in these foods and the importance of these foods. The results of scientific studies have led consumers to think about and regulate their eating habits and directed them to natural herbal sources that have negatively affected their thinking about widely used synthetic additives. With these developments, research on the acquisition, development and diversification of natural antioxidants from plants continued to increase, and medicinal and aromatic plants and spices became the focus of research. Oleoresins, known as liquid spices, have physiological activities that prevent certain types of cancers, cardiovascular diseases and aging, strengthen the immune system, cholesterol, blood pressure and blood sugar lowering effect. In the study, linseed and ginger oleoresins, which are superior to raw products, are obtained in phenolic and fatty acids concentrated form, which can be used for various purposes as both food additives and functional products, and the solvent extraction conditions used in their production were optimized. For this purpose, Three Factor-three Level Box-Behnken surface test pattern was created according to the test parameters and extraction process was performed. Extraction temperature, extraction time and sample/solvent ratio were determined as variable parameters. The effect of these variable parameters on extraction yield, total amount of phenolic and radical scavenger powers were studied. In the evaluation of these effects; Design-Expert ® software program was used. The total phenolic content, antiradical activity and extraction yield of flax seed were optimized for high oleoresin; sample solvent ratio was 1/35, temperature 41.3°C and extraction time was also 27 minutes. In ginger, the conditions in which the program responses are maximum are optimized; sample solvent ratio is 1/40 temperature 42.5°C and extraction time is 22 minutes.
