  Effects of Dietary Fibers Obtained from Cold-Press By-products on the in vitro Digestion of Spirulina

  Berktas, Serap

  This study aimed to investigate the effects of dietary fibers obtained from cold-pressing by-products on the bioactivity of Spirulina (SP) during in vitro digestion. For this purpose, insoluble dietary fibers (CCDL and KCDL) were extracted from cold-pressing by-products of flaxseed and black cumin. SP was combined with CCDL and KCDL, and subjected to an in vitro digestion protocol (INFOGEST). The results showed that the total phenolic content of SP decreased after oral and gastric digestion with the addition of dietary fiber. After small intestinal digestion, the total phenolic content increased. Antioxidant activity values (DPPH and ABTS) decreased in the presence of dietary fiber, while chlorophyll values increased after small intestinal digestion. In particular, in the presence of CCDL, the chlorophyll content increased from 1.61 mg g(-1) to 4.48 mg 2 g(-1) after small intestinal digestion. Furthermore, the bioactivity values of SP after in vitro digestion varied depending on the type of dietary fiber. While KCDL was effective in increasing phenolic compound content, CCDL was more effective in increasing chlorophyll content. Considering the bioactivity values of SP after oral, gastric, and small intestinal digestion, it was determined that the values increased especially in the small intestine. This highlights the possibility that the bioaccessibility and therefore the bioavailability, of SP can be increased through the incorporation of dietary fiber. The addition of bioactive compounds to the development of functional foods rich in dietary fiber has advantages for the food industry in terms of designing and improving healthy foods. This study emphasizes that the in vitro digestion of Spirulina is regulated in the presence of CCDL and KCDL, and that the addition of dietary fibers may contribute to the potential health benefits of Spirulina.

  An Analysis on The Relationship of Organic Honey Production and The Number of Producers with Growth, Employment, and Agricultural Employment in Türkiye; [Türkiye’de Organik Bal Üretimi ve Üretici Sayısı ile Büyüme, İstihdam ve Tarımsal İstihdam Arasındaki İlişkinin Tespitine Yönelik Bir Analiz]

  Merdan, Kurtuluş

  The growing world population has driven humanity to produce more food, potentially leading to the neglect of quality and safety in food production. Evolving life conditions and technological progress have altered the consciousness level of humanity, bringing about new demands in some communities due to high income. Organic beekeeping has developed within this structure and tends to flourish as a model in Türkiye. Organic beekeeping has increased the income from beekeeping. It is practiced in natural unspoiled areas with no conventional feeding and chemical pesticides and requires supervising all processes through inspection and certification. Besides organic honey, the most common organic beekeeping product, organic bee products include bee pollen, propolis, royal jelly, beeswax, and bee venom. This study presents the economic analysis of organic honey production volume in Türkiye. For this purpose, the short and long-term relationships of organic honey production and the number of producers with economic growth, employment, and agricultural employment were analyzed. In addition, organic honey production and the number of organic honey producers were examined as driving forces for growth, employment, and agricultural employment. In this context, annual time series data between 2004 and 2022 were used as the sample. According to the analysis, organic honey production, an independent variable, had no long-term relationship with employment and agricultural employment variables, whereas it had a long-term relationship with the growth variable. The number of organic honey producers, another independent variable, was found to have no long-run relationship with the employment variable; however, it had a long-term relationship with the growth and agricultural employment variables. The findings of the study indicated that organic honey production did not drive growth, employment, or agricultural employment. On the other hand, the number of organic honey producers led to growth, yet not to employment or agricultural employment.

  The Effects of Boron (Orthoboric Acid) Supplementation into Diets on Serum Lipid and Protein Profiles of Hens During Late Laying Period

  Kaya, Hacer; Macit, Muhlis

  This study was carried out to determine the effects of boron addition into the diets on serum parameters of hens. A total of 288 Lohman laying commercial hybrid chickens of 62 weeks were fed for 12 weeks with four different rations containing basal feed 0 (B0), 50 (B50), 75 (B75) and 150 (B150) mg / kg B. Each group was replicated in 18 cages, four hens per cage. During the study, 16 hours lighting program was applied, feed and water were given as ad-libitum. The effect of boron supplementation was not significant on the rates of diacylglycerol and hydrocarbon+cholesterol esters (P>0.05) but the rates of polarlipid, triacylglycerol (P<0.05), and serum total cholesterol (P<0.01) were found significant. Lipid peroxidation values of groups fed with diets including 75 and 150 mg/kg B were determined lower than others. Addition of ration B affected different molecular weight proteins at different levels. In conclusion, it has been determined that the addition of B at different levels into the diets of laying hens during late laying period significantly influenced the serum lipid peroxidation, serum lipid and serum protein profile, but further researches are needed to clarify the changes related to the effects of B addition into diets on mentioned parameters of laying hens.

Ayrıca, kalite kriterlerinden, tane iriliği oranı (%), bin tane ağırlığı (g), hektolitre ağırlığı (kg) ve ham protein oranı (%) belirlenmiştir. İncelenen bütün tarımsal özellikler yönünden çeşitler arasında önemli farklar bulunmuştur. İki yıllık ortalamalar ışığında en yüksek tane verimi Fahrettinbey (623.66 kg/da), Sladoran (596.41 kg/da) ve Çumra-2001 (579.32 kg/da) çeşitlerinden, en düşük tane verimi ise Çıldır-02 (409.15 kg/da) ve Özdemir-05 (425.44 kg/da) çeşitlerinden elde edilmiştir. En yüksek 1000 tane ağırlığı, hektolitre ağırlığı ve tane iriliğine sırasıyla Fahrettinbey, Sladoran ve Çumra-2001 (49.84, 47.97 ve 47.32 g; 70.76, 70.61 ve 69.58 kg; % 92.00, 90.25 ve 90.75) çeşitleri, en yüksek ham protein oranına ise Çıldır-02 (% 11.74) ve Efes-98 (% 11.69) çeşitleri sahip olurken, en kısa bitki boyu ise Sladoran çeşidinden (96.42 cm) elde edilmiştir. Bu çalışma sonucunda verim ve kalite özellikleri bakımından düşünüldüğünde, Fahrettinbey, Sladoran ve Çumra-2001 çeşitlerinin, diğer çeşitlere göre Bafra Ovası koşullarında umutvar çeşitler olduğu sonucuna varılmıştır.
