In this study, the effects of the combined and separate applications of two plant activators Ortho Silicon (Si, Optysil, 0.5 mL L-1) and Ascophyllum nodosum-based seaweed extract (ANE, KelpGreen 2.5 ml L-1) were tested by two applications after fruit set 15 days intervals to table grapes cvs. Gök Üzüm and Müşküle in a producer vineyard at Hadim town of Konya province in middle Anatolia37°2'15\"N 32°34'53\" E, 1060 m above sea level. The effects of the applications on ripening, cluster and berry characteristics and post harvest shelf life during 10 days of storage at room conditions were analyzed. Both plant activators provided an increase in cluster size and an improvement in ripening. Si+ANE was more effective on the maturation and quality retention during the post-harvest shelf-life period. All applications provided reduction in weight loss (WL), decay rate and berry dullness, and it reduced berry separation force due to the drying of the peduncle and decreased the maturity index (MI) increase in the post harvest period. Thus, it contributed to the formation and retention of fruit quality. According to the data obtained from this study, improvements in the sustainable preservation of table grape quality can be achieved by applying Ortho Silicon and A. nodosum based seaweed extract separately and together between after fruit set and before veraison.\u0000","PeriodicalId":125980,"journal":{"name":"Selcuk Journal of Agricultural and Food Sciences","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122846179","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Five different groups of meatballs were produced: C: control meatballs with breadcrumbs, Gf1: meatballs with buckwheat flour, Gf2: meatballs with chickpea flour, Gf3: meatballs with corn flour and Gf4: meatballs with millet flour. The chickpea flour increased the protein content of raw meatballs (P < 0.05). The cooking yield results were higher in gluten-free meatballs than in control samples (P < 0.05). Chickpea flour (Gf2) and corn flour (Gf3) were the most effective flours for reducing the diameter of meatballs (P < 0.05). The highest antioxidant activity was found in the meatballs with buckwheat flour (Gf1) (P < 0.05). The chickpea flour improved the texture of the meatball samples (P < 0.05), while corn and millet flour increased the hardness and chewiness values of the meatballs (P < 0.05). Millet flour decreased the flavour score compared to the control (P < 0.05), whereas the other gluten-free flours had no significant effect on all sensory properties of the meatballs (P > 0.05).

The solar tunnel dryer used in the study was built at Isparta University of Applied Sciences, Department of Agricultural Machinery and Technologies Engineering. The dryer consists of a flat plate solar collector, drying tunnel, solar cell module and a small axial fan. During the drying process, solar radiation, drying air temperature, relative humidity and air velocity were measured continuously in different parts of the dryer. At the same time, the mass loss of the melon slices was measured every two hours during the drying period. On the other hand, colour measurements were made on untreated and pre-treated melon slices, fresh and after drying, before and after the trials. Fresh melon samples were washed with tap water, and cut in half with a knife, the core in the middle was removed and sliced by hand in a half-moon shape without peeling before pre-treatment. 1% ascorbic acid was applied to the fruits as a pretreatment. After the preparations, the solar tunnel drying behaviour of untreated and pretreated sliced melon samples was investigated. Drying characteristic curves were evaluated according to five different mathematical models. In this study, it was determined that the L*, a* and b* values of melon varieties were preserved without pretreatment.

Three winter canola cultivars (Linus, PR44W29, Es Neptune) were used as material and six different nitrogen doses (0, 50, 100, 150, 200, 250 kg N ha-1) were applied. The research was established to according to the experimental design of split plots in randomized blocks. Half of the nitrogen fertilizer applications were given in the form of ammonium sulfate (21% N) at planting and the remaining half was given as urea (46% N) at the beginning of flowering. As a result of the study, it was determined that plant height, number of branch on the main stem, number of capsule per plant, capsule length, thousand seed weight seed yield, crude oil yield and crude protein ratio increased, while crude oil ratio decreased in winter canola varieties due to increasing nitrogen doses. As a matter of fact, the plant height values varied between 92.6 and 128.5 cm (respectively, LinusxN50 and PR44W29xN250), number of branch (no. main stem-1) of 2.4-5.7 (LinusxN0-PR44W29xN250), number of capsule (no. plant-1) of 103.9-218.9 (Es-NeptunexN0-PR44W29xN150), capsule size of 5.3-6.6 cm (Es-NeptunexN0-LinusxN250), number of seeds in the capsule of 22.5-30.0 (Es-NeptunexN100-PR44W29xN250), thousand seed weight between 3.2 and 4.7 g (PR44W29xN0-LinusxN200), seed yield of 1361-5373 kg ha-1 (Es-NeptunexN0-PR44W29xN250), crude oil yield between 547.0 and 2466.0 kg ha-1 (Es-NeptunexN0- PR44W29xN150) and crude protein ratio values ranged of 16.2 23.9% (Es-NeptunexN0-LinusxN200).It was determined that there were increases in the values of these properties with increasing nitrogen doses in general. In terms of crude oil ratio, the lowest value was determined at PR44W29xN0 with 39.2%, and the highest value was determined at PR44W29xN50 with 46.3%. It has been determined that there are relatively decreases in crude oil ratios with increasing nitrogen doses. The main purpose of cultivation of oil seed crops is to increase the oil yield per unit area. From this point of view, it was concluded that PR444W29 cultivar among the cultivars considered in the study would be more suitable in terms of oil yield with 150 kg N ha-1 application for the regions similar to the conditions in which the study was conducted.\u0000","PeriodicalId":125980,"journal":{"name":"Selcuk Journal of Agricultural and Food Sciences","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121727848","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to compare the effects of molasses and powdered molasses used as natural curing agents in sucuk, a control (K) group containing sodium nitrate was formed. The application of the natural alternative curing process in sucuk production causes a decrease in the pH value and TBA content of the samples during the ripening period, whereas causes an increase in the nitrosomyoglobin and residual nitrate contents. As a result of microbiological analysis, it was determined that the natural alternative curing process increased (P<0.05) the number of LABs and there was no significant change in the total yeast-mold numbers during the ripening period (p>0.05). In addition, total Coliform group bacteria were not detected in sucuk dough and sucuk samples on the last day (5th day) of the ripening period.

RCA 5.3 and MRS 5.2 media were used for L. delbrueckii subsp. bulgaricus counting, ST Agar and M17 Agar were used for Stretococcus thermophilus counts. While using MRS-Bile Agar and RCA-Clindamycin Agar for L. acidophilus enumeration, Bifidobacterium spp. counts were performed using MRS-NNLP medium. 5 out of yoghurt samples (A, C, D, and E) did not reveal satisfactory recovery (< 5 log CFU/g) for L. delbrueckii subsp. bulgaricus colonies on MRS 5.2 Agar while L. delbrueckii subsp. bulgaricus colony counts on RCA 5.3 Agar below 5 log CFU/g for same tested 4 samples (A, C, D, and E).
