Inulin, a prebiotic utilized in the food and pharmaceutical industries, promotes the growth of beneficial bacteria in the colon, thereby enhancing human health. Although inulin is commercially produced from chicory and artichoke, Inula helenium roots offer a high potential for inulin production. The aim of this study is to investigate the prebiotic activity of inulin (inulin‐P) from I. helenium roots on Lactobacillus rhamnosus, as well as its ability to produce synbiotic microcapsules and the effects on probiotic viability during freeze‐drying, in vitro gastrointestinal (GI) digestion, and storage. First, the effect of inulin‐P on L. rhamnosus viability and short‐chain fatty acid (SCFA) production was compared to other commonly utilized prebiotics. The findings revealed that inulin‐P remarkably promoted the growth and SCFA yield of L. rhamnosus for 48 h of fermentation and 28 days of storage. Then, L. rhamnosus was encapsulated with inulin‐P and commercial inulin to compare its survival throughout storage and the GI tract. Inulin‐P microcapsules outperformed in terms of viability during storage (7.98 log CFU/g after 30 days at 4°C). Furthermore, inulin‐P microcapsules were heat‐resistant and protected L. rhamnosus from GI conditions, resulting in a high survival rate (89.52%) following large intestine simulation, which is ideal for increasing customer benefits. Additionally, inulin‐P microcapsules exhibited similar physical characteristics to commercial inulin. Consequently, this study revealed that inulin‐P, which is easy to produce, low‐cost, and has industrial application potential, could be used as a good carrier for the synbiotic encapsulation of L. rhamnosus. Practical Application: Inulin is a prebiotic that promotes the activity and growth of beneficial bacteria in the human gut. Although commercial inulin is currently produced from chicory root and artichoke, Inula helenium root is a potential raw material for inulin production. In this study, inulin was produced from I. helenium roots with a low‐cost and easy production method, and it was determined that this inulin was an effective carrier in the synbiotic encapsulation of L. rhamnosus. This inulin exhibits superior prebiotic activity and encapsulation efficiency compared to commercial inulins like Orafti® GR and HPX and can be easily integrated into industrial production.

Chronic diseases cannot be treated completely, and, therefore, often require repeated treatments. This issue leads to long-term drug utilization. However, medical foods can offer alternative natural drugs in the management and treatment of chronic diseases. Medical foods are specially formulated food to meet the particular nutritional requirements of patients affected by certain diseases. They play an important role in nutritional support for patients in clinical applications such as deglutition, dyspepsia or eating disorders. Moreover, they considerably enhance the quality of living of patients by reducing drug usage, preventing complications that may arise through the overreliance of drugs, and reducing the expenses of treatments. The nutritive value of medical foods can be regulated and personalized depending on the disease. Since they are not drugs, they exempt from regulations applying to drugs. Each medical food is formulated specifically for the relevant chronic disease. However, there are no studies in the literature that provide examples of medical foods for different diseases available in the market. The examination and compilation of medical foods, including examples from the market, is vital both in terms of creating new products and filling the gap in the relevant literature. Consequently, the aim of this review is to explain the use of medical foods for Alzheimer's, Parkinson's, anxiety and sleep disorder, pain syndrome, cancer, congenital metabolic disorders, diabetes mellitus, and indicate why should be used as a nutritional supplement for these chronic diseases.

TEZ10839 Tez (Yüksek Lisans) -- Çukurova Üniversitesi, Adana, 2018. Kaynakça (s. 81-100) var. xiv, 101 s. : res. (bzs. rnk.), tablo ; 29 cm. Bu çalışmada Ege bölgesi’nin Urla yöresi ve Marmara bölgesi’nin Şarköy yöresinde yetiştirilen Merlot üzümlerinden kırmızı şarap üretilmiş ve bu şarapların bileşimi, fenolik özellikleri, aroma ve duyusal özellikleri araştırılmıştır. Şarapların fenolik özellikleri spektrofotometrik yöntem ile, aroma maddeleri GC-MS/FID ile, duyusal özellikleri ise koku ve lezzet profil analizi ile gerçekleştirilmiştir. Urla yöresine ait şarapta 59 adet ve Şarköy yöresine ait şarapta ise 63 adet aroma bileşiği tanımlanmıştır. Yüksek alkoller, esterler ve uçucu asitler her iki şarapta da en baskın olan aroma grupları olmuştur. Şarabın aromasına pozitif etki yapan esterler ve lakton bileşikleri miktarı Şarköy yöresi Merlot şarabında Urla yöresine göre daha yüksek bulunmuştur. Toplam fenolik bileşikleri, tanen ve antosiyanin miktarlarıda Şarköy yöresi merlot şarabında daha yüksek bulunmuştur. Duyusal analiz sonuçlarına göre Urla yöresine ait şarabın kırmızı meyve, siyah meyve ve kuru meyve kokuları ile Şarköy yöresine ait şarabın ise vanilya, kırmızı meyve ve siyah meyve kokuları ile karakterize olduğu tespit edilmiştir. Şarköy yöresi Merlot şarabının Urla yöresine göre fenolik bileşiklerce daha zengin, daha meyve aromalı, buruk, gövdeli ve damakta daha uzun özellikte olduğu belirlenmiştir. İki bölge karşılaştırıldığında yüksek kalite Merlot şarabı için Şarköy yöresinin daha uygun bir bölge olduğu söylenebilir. In this study, red wines were produced from Merlot grapes, which grown in Urla-Aegean region and in Şarköy-Marmara region, and the composition, phenolic properties, aroma and sensory properties of these wines were investigated. Phenolic properties were determined with spectrophotometric method and aroma composition of wines were identified and quantified with GC-MS/FID. 59 aroma compounds were identified in wine of Urla region and 63 aroma compounds were found in wine of Şarköy region. Higher alcohols, esters and volatile acids have been determined as the most dominant aroma groups in both wines. In Şarköy region wines the amounts of esters and lactones, having a positive effect on wines, were found to be higher than Urla region. The amounts of total phenolic compounds, tannins and anthocyanins were determined to be higher in Şarköy region wines. According to the results of sensory analyses; it has been found that wine of Urla region is characterized by red fruit, black fruit and dry fruit odors and wine of Şarköy region is characterized by vanilla, red fruit and black fruit odors. It has been determined that the wine of Şarköy region is more rich in phenolic compounds, more fruit-flavored, astringent, full bodied and longer on the palate compare with the wine of Urla region. When two region is compared, it can be state that Şarköy region is more suitable for high quality wine. Bu çalışma Ç.Ü. Bilimsel Araştırma Projeleri Birimi tarafından desteklenmiştir.
