In this study, the effect of green tea powder (GTP) in ice cream production on the ice cream properties and viability of probiotic bacteria [Bifidobacterium animalis ssp. lactis (Bifidobacterium BB-12) (P)] was investigated. Four ice cream groups (Control, C: without GTP and P; Probiotic Control (PC): with P; P+1% GTP; P+3% GTP samples) were produced. Bifidobacterium BB-12 (P) was added at 108 cfu/mL. pH, overrun, color, first dripping time, complete melting time and sensory properties were carried out on the second day. P was counted at 2, 15, 30, 45, 60, 75 and 90 days of storage. Bifidobacterium BB-12 number of PC was 6.54 log cfu/g at the 90th day. Bifidobacterium BB-12 number of PC was 7.10 log cfu/g, P+1% GTP sample was 6.48 log cfu/g and P+3% GTP sample was 5.84 log cfu/g at the 75th day. Bifidobacterium BB-12 number of PC was 7.24 log cfu/g, P+1% GTP sample was 6.59 log cfu/g and P+3% GTP sample was 6.69 at the 60th day. Sensory properties and probiotic counts showed that P+1% GTP sample could be accepted as a probiotic ice cream until day 75. Hence, GTP could be successfully used as a functional ingredient in the production of probiotic ice cream.

Acar, Emine; Kankal, Murat; Akçay, Fatma; Şan, Murat
Agriculture is affected by climate change, such as extreme increases or decreases rainfall and temperature patterns. It is possible to research that effect by using trend analysis methodologies. This paper investigates trends of monthly total rainfall and mean temperature data of nine selected stations from agricultural regions of Turkey between 1969 and 2020. To the end, the classical Mann–Kendall, Innovative Trend Significance Test (ITST), and Innovative Polygon Trend Analysis (IPTA) with Star Graph methods providing the opportunity to examine seasonal behavior were used for trend analysis. The analysis reveals that about 96% of all monthly rainfall in the Mann-Kendall test has no trend. However, nearly all stations tend to decrease (increase) in November (September) in both innovative approaches. For temperature, it is seen that increasing trend or no trend dominated in general. There were increasing trends in the innovative approaches throughout the year except for April. Temperatures have increased significantly throughout the year in all regions over the last decades. With the help of IPTA, it was also concluded that the seasonal internal variability of rainfall over the entire time and in the last 30 years is quite complex and persists in all agricultural regions. The results show that irregular changes in rainfall and rising temperatures in all stations negatively affected crop yield and/or required more irrigation. In addition, according to the results obtained by comparing trend methods, innovative approaches are very insistent on determining of trend and provide additional information through a visual review of trend behaviors.

İlyasoğlu, Huri; Arslan Burnaz, Nesibe; Arpa Zemzemoğlu, Tuba Eda
Consumers' demand for healthy foods has been increased. The aim of this study was to develop a functional cookie from wheat flour with flaxseed (FS) and Cornelian cherry (CC). The effects of the levels of FS flour (10–30 g for 100 g composite flour) and CC powder (2–10 g for 100 g composite flour) in the cookie formulation on the cookie properties were investigated by using response surface methodology. The lightness of the cookies was decreased with the addition of the FS and CC. The incorporation of the FS into the formulation enhanced the content of omega-3 fatty acids. Both FS and CC enhanced the total phenolic contents (TPCs) and antioxidant capacity of the cookies. Moreover, they did not have effects on the hardness and overall acceptability. The developed cookie contained FS (23.6 g 100 g−1) and CC (10 g 100 g−1) that provided α-linolenic acid (16.5 g 100 g−1), TPC (340.2 mg GAE 100 g−1), and antioxidant capacity (996.6 μmol TEAC 100 g−1). Our study indicated that the combination of wheat flour with FS with CC can have the potential to enhance the nutritional and functional values of the cookies. Novelty impact statement: The combination of wheat flour with flaxseed and Cornelian cherry in the cookie formulation enhanced the contents of omega-3 fatty acids, total phenolic content, and antioxidant capacity of the cookies. The developed cookie may be an alternative product for consumers who look for healthy bakery products.

Aykas, Didem-Peren; Menevseoglu, Ahmed; Gunes, Nurhan
Flaxseed oil is one of the popular edible oils, and its adulteration has become a concern because of its high commodity value. Therefore, there is a need to detect adulterated flaxseeds with a rapid, non-invasive, and simple method to keep the quality of flaxseed oil. This study aimed to develop a machine learning algorithm and information theory to detect adulterated flaxseed oils by vibrational spectroscopy units combined with chemometrics. Oil spectra were collected with portable/handheld vibrational spectroscopic units and analyzed using conditional entropy, support vector machines (SVM), and soft independent modeling of class analogy (SIMCA) to generate classification models to identify the pureness of oils and partial least square regression (PLSR) to predict the adulterant levels and fatty acid distributions. Conditional entropy showed that two or three wavenumbers/shifts could discriminate the oils using machine learning algorithms with an accuracy of over 95%. SIMCA models determined the oils with an interclass distance (ICD) over 1.1. Specifically, the Fourier transform mid-infrared (FT-MIR) unit provided the best classification of the oils with ICD over 4.9. All instruments showed good performance in predicting fatty acids and adulteration levels with rval≥0.89 and standard error prediction (SEP) ≤1.7%. Overall, these portable/handheld units showed great potential for rapid, simple, and non-invasive monitoring to identify adulterated flaxseed oils.

Tan, Mustafa; Yolcu, Halil
Forage crops cultivation area in Turkey is 2.312 million ha in 2020. The rate of forage cultivation in the total agricultural area is 6.1%, and its rate in the field land is 12.3%. Lucerne, silage corn, oat, vetch, and sainfoin are main forage crops in Turkey. The amount of produced is 16.8 million tons of hay and 48.8 thousand tons of seeds. The forage crop cultivation areas have increased by 206% since the beginning of the 2000s due to the government subsidies. However, shortage of quality roughage is still a big problem for animal husbandry of the country. For this reason, new strategies should be developed to increase forage cultivation areas by considering global warming, drought, and climate change. In order to meet the need for roughage, it is necessary to expand the cultivation area of forage crops as winter catch crops and second crops. In addition, some of the fallow fields should be utilized by growing drought-resistant forage species. The fields abandoned due to different problems should be used for the cultivation of suitable forage crops.

Abstract: This research was intended to determine the effect of different cereal and pulse flours and commercial gluten-free flour on the mineral content, fatty acid composition, and volatile compounds of the gluten-free tarhana (cereal-based fermented dry soup). In order to produce the gluten-free tarhana, white bean (BF), chickpea (CF), commercial gluten-free (GWF), yellow lentil (LF), and rice (RF) flours were used. The Mg, K, Al, and Mn contents of tarhanas obtained using different pulse and cereal flours were found to be quite high compared to tarhanas produced with commercial GWF. The utilization of different cereal and pulse flours in the tarhana formulation resulted in an increase in the percentage (30.37–51.47%) of the total polyunsaturated fatty acid (TPUFA). The highest (452.4 µg/g) and the lowest (241.17 µg/g) total concentration of all compounds were detected in BF and GWF, respectively. The highest number (21) of compounds belonged to terpenes and terpenoids, followed by acids, hydrocarbons, alcohols, aldehydes, esters, ketones, and alkanes. Practical Application: This study shows that cereal and pulse flours can be used to produce acceptable tarhana with improved nutritional quality in terms of mineral and fatty acid contents. The results of the current study may be useful and applicable to food manufacturers producing gluten-free products for celiac patients.
