“…The differences in samples arise from their unique proportions and combinations of absorbed energy, primarily associated with the stretching and vibrations of various bonds like C-H, N-H, S-H, C C, C C, C-N, and O-H within the NIR spectral range (700-2500 nm) (Prananto et al, 2020). NIR spectroscopy has found extensive application in the evaluation of agricultural and food products, though it is more commonly employed in food research compared to agricultural applications (Keskin et al, 2019;Kinhal, 2022;Pandiselvam et al, 2022). In agriculture, NIR spectroscopy has been employed to examine the nutritional status of crops, the determination of harvest time, the detection of diseases, pests, effects of toxins and drought in crops, breeding programs, soil properties, and so forth (Kinhal, 2022;Tsuchikawa et al, 2022).…”

“…Traditionally, soil, plant leaf, or tissue ionomic analyses are essential, especially at early stages, for determining the type and quantity of fertilizers needed for optimal plant growth, yield, and quality (Acosta, Quiñones, et al., 2023). However, these analyses involve multiple laboratory processes that demand significant time, energy, labor, chemicals, and expenses (Keskin et al., 2022). Moreover, they expose laboratory staff to chemicals posing potential health risks.…”

BackgroundPistachio nuts provide many health benefits in human diet. Nutrient levels in plant leaves and fertilizer schedules are determined based on traditional soil and leaf chemical analyses. However, these methods require additional labor, time, and cost, which is why most farmers do not prefer them and cannot detect nutrient deficiencies in time. Fast, easy‐to‐use and low‐cost nutrient level assessment techniques are needed.AimThis study aims to explore the viability of near‐infrared reflectance spectroscopy (NIRS) as a fast, user friendly, and cost effective technique for evluating the major macro‐ and micronutrient contents of dried and ground pistachio leaf sample.MethodsThe feasibility of NIRS for estimating nutrient contents was investigated by analyzing samples from 200 pistachio trees. Dried and ground pistachio leaves were subjected to NIRS analysis. PLSR (Partial least square regression) analyses were performed to develop nutrient content prediction models using spectral information of samples.ResultsIt was found that the NIRS system had a very good potential to estimate the K, Ca, Cu, and Mg contents of the leaf samples (R2 > 0.80). It was also found that Fe and Mn concentrations could also be estimated with good accuracy (R2 = 0.70–0.80). However, the NIRS system did not give good results for the prediction of N, P, and Zn (R2 < 0.40).ConclusionIn conclusion, the NIRS system can be used to quickly, easily, and economically assess the K, Ca, Cu, Mg, Fe, and Mn contents of dried and ground pistachio leaves. This technique has the potential to improve nutrient management practices in pistachio farming within a sustainable and environmentally conscious framework. Fourier transform NIRS (FT‐NIRS) can provide valuable insights by complementing rather than replacing traditional chemical analysis. Laboratory analysis is still required for definitive nutrient content information, but FT‐NIRS can significantly reduce the reliance on such analysis, thereby mitigating the environmental impact caused by the excessive use of chemical fertilizers and minimizing the health risks to laboratory staff. In addition, the rapid information‐gathering capabilities of the FT‐NIRS can be emphasized.

“…During the application of heat treatments, the nutritional value of the food decreases significantly due to the destruction of heat-sensitive phenolic components (Choi et al, 2006). However structure and composition of the foods and the applied heat treatments may cause an increase or decrease in the amount of phenolic compounds (Sakač et al, 2011), antioxidants (Meral, 2016) and color (Aktaş et al, 2013;Keskin et al, 2019;Arslan et al, 2023) properties. Keskin et al (2021b) found that the highest amounts of phenolic were in the black carrot samples dried by HA and IMW compare to freeze drying.…”

The quality of agricultural crops is influenced by growing conditions and post-harvest processes, including drying. Moreover, the total phenolic and total antioxidant content in the product's structure and composition can be either positively or negatively affected by the heat treatments applied during drying. Additionally, the specific growing conditions and methods of water removal can lead to the development of distinct drying characteristics. There was no study comparing the drying kinetics and quality parameters of organic (OBC) and conventional (CBC) black carrot in the literature studies. In this study were aimed that mathematically modelling the drying kinetics for OBC and CBC with IMW (150, 300, 450 W) and HA (60, 70, 80°C), determining their differences and evaluating the effects of methods on quality properties. The results showed that L* and ΔE values of the final products increased significantly by increasing the power and temperature levels applied during drying and the powder samples were lighter in color compared to the fresh samples. The total phenolic and total antioxidant capacity values were higher in fresh OBC samples compared to the conventional variety. This result shows that OBC is superior to the CBC in terms of higher total phenolic and total antioxidant content. The activation energy (Ea) values of OBC and CBC dried by IMW and HA were calculated as 8.41x10-3; 8.40x10-3 Wg-1 and 25.50; 19.72 kJ mol-1, respectively. The Logistic and Verma were the best fit models for describing IMW and HA drying kinetics, respectively. The samples obtained with IMW drying, which resulted in a shorter drying time, were more effect in terms of preserving and increasing the total phenolic and antioxidant content compared to dried samples with HA. The results showed that that the temperature/power levels applied to the products during the drying process, thus the drying times and the methods of removing moisture from the product are effective in the preservation of the total phenolic components.
