In the study; fruit skin color parameters, fruit flesh firmness and total soluable solid (TSS) ratios, as well as total acidity, total phenolic substance, total monomeric anth°Cyanin amounts and total antioxidant capacity were determined. After the fruits were harvested, they were immersed in three different doses (0-2-4%) of calcium chloride (CaCl2) solution for 5 minutes. The fruits removed from the solution were kept to dry. The fruits were stored for 14 days in a cold store with a temperature of 1-2°C and a relative humidity of 90±5%. Before the storage and on the 7th and 14th days of storage, the fruits samples were taken and kept on the shelves in the rooms with a temperature of 21±1°C and a relative humidity of 60±5%for 3 days. Measurements and analyses of fruit quality parameters were made in the samples taken from the fruits that were kept on the shelf for three days. As a result of the study, it was determined that 4%CaCl2 application was effective in maintaining fruit flesh firmness. In fruits kept on the shelf for 3 days after 14 days of storage, SSC of 4%CaCl2 treatment was found to be higher than the control treatment. Compared to the control, 4%CaCl2 caused a significant increase in the total phenol content. The highest total monomeric anth°Cyanin content and total antioxidant capacity was determined in the control treatment. While there were no significant changes in L* values between treatments, a* and b* values were found to be higher in 2%CaCl2 treatment. In the light of the data obtained, it was concluded that 4%CaCl2 application had a positive effect on the shelf life of strawberry fruits.

Gamze Hatip | Şeyda Türkay | Kevser Karaman
Yeast cells are carriers with great potential for encapsulation of both hydrophobic and hydrophilic compounds, due to protection from external environmental influences, controlled release, biocompatibility and biodegradability. The promising research results on the encapsulation of bioactive substances in the recent past promise a bright future in many fields such as agriculture, medicine and cosmetics, including functional food. The significant decrease in the stability of many bioactive compounds due to environmental conditions (heat, humidity, oxygen, etc.) has revealed the necessity of preserving the stability of these types of compounds by encapsulation process. After the recognition of yeast cells as suitable carriers for water-soluble flavor encapsulation, the possibilities of using various yeasts, especially Saccharomyces cerevisiae, in the encapsulation of various oils, vitamins, flavors and some phenolic compounds have been the subject of various scientific studies. The fact that the encapsulation process using yeast cells offers some advantages compared to other encapsulation methods has made the use of yeast cells in the encapsulation process very popular and there has been an increase in studies conducted in recent years. In this study, various scientific studies on the possibilities and effectiveness of the use of yeast cells in the encapsulation of various structures, especially various bioactive compounds, have been reviewed.

Taner Yıldız | Elçin Yeşiloğlu Cevher
Mechanical properties provide information to design and develop suitable machines (equipment) for processing, transporting, and conveying chestnuts. Four chestnut cultivars that have not been studied before were investigated in the study carried out for this purpose. Some engineering properties of Macit 55, Akyüz, Ali Nihat, and Bouche de Betizac chestnut cultivars were determined and compared. The mechanical properties were determined by rupture force, rupture energy, deformation, and firmness values. The friction coefficients of chestnut varieties on a galvanized sheet, stainless steel, and rubber surfaces were investigated. Mechanical properties were determined using a Universal Testing Machine. The values obtained from the samples were obtained by compression between the parallel plate along the X, Y, and Z axes. For the static friction coefficient, while the galvanized sheet surface had the lowest value (0.145), the rubber surface had the highest value (0.212). For rupture forces, the force required to break the chestnut at the Z loading axis position (714.09 N) was higher than the required force at the Y loading axis position (396.35 N) of the fruit.

The aim of this study was to investigate the effects of resveratrol extract (RE) and curcumin extract (CE) added to diet on the serum biochemical parameters and hepatic enzyme levels as Alanine Aminotransferase (ALT), Aspartate Aminotransferase (AST), Alkaline Phosphatase (ALP), and Gamma Glutamyl Transferase (GGT) of broiler. A total number of 200, 0-day-old male broiler chicks (Ross 308) were used in the study. The animals were divided into 5 groups; the control group was fed only basal diet but groups RE-1, RE-2, CE-1 and CE-2 had 250 mg/kg RE, 500 mg/kg RE, 250 mg/kg CE and 500 mg/kg CE, respectively, added to their diets. At the end of the study, 10 randomly selected animals from each group were slaughtered and blood was taken from the vena jugularis and used in the analysis. In the examinations, it was determined that the serum creatinine level in the group RE-1 and the Lactate Dehydrogenase (LDH) level increased significantly in the group CE-2 group. In addition, it was determined that the albumin/globulin ratio in the RE-2 group, and the magnesium (Mg) level increased significantly in the RE-1 and RE-2 groups. It was found to be statistically similar in all groups that serum glucose, cholesterol, triglyceride, urea, blood urea nitrogen (BUN), creatine kinase (CK), ALT, AST, ALP, GGT, amylase, total protein, albumin, globulin, calcium (Ca) and phosphorus (P) levels. As a result, it was observed that the additives applied did not have an effect on serum hepatic enzymes and partially affected other routine biochemical parameters.

This study aimed to investigate the body weight and some body measurements in Central Anatolian Merino sheep regarding ages and to carry out a comparative analysis between them. The study included a total of 60 animals aged 2, 3 and 4 years. The sheep were fed daily with hay, vetch, alfalfa and limited amount of concentrated feed (400 g head-1) until the pasture period, and pasture grass and mixed grass-clover hay during the pasture period. The live weights of the sheep of different ages in the farms were measured with a digital scale, and some body size were measured using a measuring tape and a measuring stick. When the live weight and chest circumference values of the 4-year-old sheep were compared with the data obtained in the other age groups (2 and 3 years old), and it was statistically significant, chest width and rump height values were found to be similar to those in the 3-age group. There were significant correlations between live weight and chest circumference, between withers height and rump height and significant correlations between live weight and chest width, body length with rump height, chest width with chest depth. In addition, significant correlations were found between live weight and chest depth, and between withers height, body length, and chest depth. Present findings revealed that the Central Anatolian Merino sheep can be beneficial in the development of meat-type sheep breeding.

Sarra Bettihi | Nadia Mahdeb | Abdelouahab Bouzidi
Peganum harmala L. (Zygophyllaceae) known locally as harmel is a medicinal plant. In traditional medicine, its seeds have long been used for therapeutic purposes because of their richness in β-carboline alkaloids. This study aimed to evaluate the maternal and developmental toxicity during pregnancy by daily IP administration of 7.99 mg/kg/day (1/20 DL50) of total alkaloids extract in P.harmala’ seeds. The results summarized in confirmed pregnancy rates were high 90-100%, decreased locomotor activity, paralysis, and hypothermia. Maternal body weight and weight gain changes were statistically significant in all pregnant. Precisely, the relative weight of ovaries was significantly changed in all the groups treated. The ALAT and gamma GT concentrations show a significant change in the group treated for seven days. Significant changes in the total and indirect bilirubin levels were observed in all treated groups. The hormonal analysis showed a significant decrease in FSH levels in a treated group for seven days and two weeks, Progesterone levels were increased significantly in treated groups for seven and three weeks and increased significantly in a treated group for two groups, however, the levels of Estrogen were changed significantly only in the treated group for three. The results show a significant difference in total resorbed litters and the number of fetus deaths in the group treated for three weeks. The fetus weight in the group treated for two weeks was significant. The results show a significant decrease in the number of implantations and an increase in pre-and post-implantation loss rates, and there were no developed live or dead, and no resorbed fetuses in all treated dams, there were only implantation sites in both uterine horns. The total extract of the alkaloids in the seeds of P. harmala has adverse effects on maternotoxicity, embryonic development, and abortion.
