“…In the test of color changes of the product surface, the increases in CO 2 gas pressures were observed to have trivial effects on the surface colors of the dried apricot samples, which was not detectable with bare eye. In this regard, Sadeghi et al [37,38] reported that increasing ozone concentrations (2, 3, and 5 ppm) and exposure times (15,30,45,60, and 90 min) had no significant effects on the colorimetric factors of their raisins and figs.…”

One of the new ways of warehouse pest control is the carbon dioxide treatment, which had no residues on the target products. In the present research, at first, CO2 gas was applied to control two important pest species infesting dried apricots. Dry apricots infested with adults of Tribolium castaneum (Herbst) or Rhyzopertha dominica (F.) were exposed to CO2 gas pressures correspond to 9.1, 16.7, 23.1, 28.6, and 33.4 mol% for 24 h. The results showed higher mortality rates with increasing the gas pressures in all the experiments. The minimum and maximum losses of the pests were determined at concentrations of 9.1 and 33.4 mol%, respectively. Evaluation of CO2 gas effects on the quality characteristics of dried apricots showed no impacts on the color, brittleness, hardness, sweetness, sourness, and general acceptance of products. CO2 gas treatments at the concentration of 33.4 mol% showed no significant influences on the chemical features of dried apricots, including pH, acidity, Brix, humidity percentage, reducing sugar, and total sugar. It was concluded that CO2 gas had the potential to control T. castaneum and R. dominica in warehouses of dried apricots, without any significant impacts on product qualities.

Raisin grains are among the agricultural commodities that can benefit health. The production of raisin grains needs to be classified to achieve optimal results. In this case, the classification is carried out on two types of grains, namely Kecimen and Besni. However, inaccurate sample data can affect the performance of the model. In this study, two sampling techniques are proposed: stratified and shuffled. The proposed classification model is RF, GBT, NB, LR, and NN. This study aims to identify the performance of classification models based on sampling techniques. Classification models are applied to the seven-features dataset, and modeling is done by cross-validation. The results of the models were tested with a different amount of test data. The performance of the models was evaluated related to accuracy and AUC. The best outcomes of all models based on stratified sampling were founded on tested data of 40 percent with a mean accuracy of 85.50% and an AUC of 0.921. In comparison, models based on shuffled sampling were founded on test data of 20 percent with a mean accuracy of 88.11% and an AUC of 0.935. On the other hand, classification models based on a stratified sampling of all data splits do not all models generate an excellent category. Whereas, based on shuffled sampling, all models resulted in the excellent category. Therefore, models based on shuffled sampling are superior to stratified sampling. The result of the significant test, RF, significantly differs based on sampling techniques.

In order to solve the problem of infestation of fresh fruit after making them into candied fruit and the quality degradation caused by the infestation, a combined ozone-microwave sterilization method was used to treat four candied fruit molds.Response surface optimization analysis showed that when the ozone infusion time was at 10 min and with 560 W microwave power for 20 s, the inhibition rates of the four candied fruit molds S1, S2, X1, and H1 were 100%, 94.28%, 100%, and 100%, respectively. Moreover, according to the characterization of morphology, DNA electrophoretic profiles, and nucleic acid/protein leakage test, the integrity of the mold cell membrane was destroyed after the combined ozone-microwave treatment because of the thermal and nonthermal effects of microwave and the strongly oxidizing properties of ozone. The molds were dead because of the efflux of intracellular nucleic acid and protein and the degradation of DNA, which influenced normal cellular metabolism. Quality identification showed a better expected quality of candied fruit.
