The accurate identification of postharvest tomato freshness is critical for fruit growers to plan their storage, transportation, and wholesale processes. In this study, a method based on improved frequency-tuned (FT) visual saliency detection ResNet34 model proposed nondestructive freshness. L*, Y, H components were extracted as effective features be introduced into the original FT algorithm by performing color space analysis image processing operations tomatoes variation images with different levels. was utilized obtain maps, which combined corresponding RGB information form four-dimensional data. ResNet four-channel realize classification experimental results show that accuracy, precision, recall are 98.38%, 98.69%, 98.32%, respectively. speed single 0.0326 s. study demonstrated recognizing has effectiveness real-time performance can provide technical support vegetable production industries consumers when shopping fresh tomatoes. PRACTICAL APPLICATION: This introduces computer vision rapid assessment approach permits ascertain produce without causing damage, thereby markedly enhancing management practices such distribution. By optimizing handling processes, reduces spoilage producers ensures receive high-quality produce. study's findings intended advance food science, specific applications in technology quality control.

In this research, physical and mechanical properties, as well color changes FT-IR analyzes of 13 different wheat varieties, which are intensively produced, were examined. For purpose, Altay, Harmankaya, Çetinel, Yunus, Mufitbey, Soyer 02, Dumlupınar, Bezostaja, Sönmez, ES-26, Reis, Karaman2000, Nacibey varieties used. As a result the research Soyer-02 variety exhibited largest seed width (3.42 mm) thickness (2.96 mm), while Müfitbey had smallest (2.72 (2.36 mm). Dumlupınar showed greatest length (7.82 with having shortest (6.07 Surface area was in (53.35 mm²) lowest (36.03 mm²). Arithmetic geometric mean diameters (4.61 mm 4.12 mm, respectively), showing (3.72 3.54 Sphericity ranged from 61.22% Reis to 52.67% Dumlupınar. The thousand-kernel weight varied significantly, recording highest (46.36 g) Altay (33.58 g). Fracture resistance Bezostaja (10.89 N 11.3 N), (5.89 N). Color analysis revealed L values ranging 63.77 Çetinel 51.16 all positive 'a' values, indicating red tones, 'b' yellow (32.81) Harmankaya (24.68). broad O-H stretch vibrations (3270-3300 1/cm) Müfitbey, Soyer, suggesting high moisture or phenolic content.
