SEM-EDX characterization further verified the successful deposition of CA on the platinum surface. The oxidation peak potential of GA was observed at approximately 0.45 V. Modification with CA enhanced the GA oxidation current by 20.8 %, increasing it from 1.425 mA to 1.722 mA. The oxidation peak currents obtained from differential pulse voltammograms exhibited a linear relationship with GA concentrations ranging from 1.25 × 10⁻³ mM to 0.5 mM. Based on a signal-to-noise ratio of 3, the detection limit was calculated to be 0.32 µM. The proposed CA-modified sensor was successfully applied to quantify GA in fresh orange and lemon juice samples, without significant interference from AA or citric acid (CA).

The experiment was conducted using pulse strength variations of 1.5, 3, 4.5, and 6 kV/cm as drying pretreatment. The properties analyzed were drying rate, total phenolic, flavonoid, anthocyanin, tannin, and antioxidant capacity (FRAP, ABTS, and DPPH). The PEF significantly increased the drying rate and maintained the bioactive compounds. A pulse strength of 6 kV/cm caused a 20 % reduction in drying time compared to the untreated sample and produced the highest increase in all bioactive properties. These included total phenolic (101.97 GAE/mL), flavonoid (75.64 QE/mL), anthocyanin (11.61 mg/L), tannin (21.03 TAE/mL), and antioxidant activity (DPPH 63.59 %, ABTS 58.17 %, and FRAP 107.76 AAE/mL). The mechanism of the increase could be related to the cell electroporation, which facilitated the release of water, accelerated the drying rate, and maintained bioactive compounds.

The nutritional evaluation of the flour highlighted an interesting protein and ash content. Three free sugars were identified in the analyzed flour, with fructose being the main sugar and five organic acids, with malic acid being the most prevalent. Regarding fatty acids, monounsaturated fatty acids predominated, with oleic and linoleic acids being the major components. Seven phenolic compounds were identified by HPLC-DAD-ESI/MS, divided into three different families: phenolic acids, flavan-3-ols, and dihydrochalcone, with phenolic acids predominating, which may justify the antioxidant and antimicrobial potential evidenced by the flour. After characterization, flour was incorporated into two types of bread and the effect of this incorporation over the shelf life was evaluated. Overall, the nutritional and chemical composition of the apple flour obtained in this study makes it a viable alternative for application in the bakery and pastry industry, thus creating alternative products and health promoters for the consumer.

This study aimed to investigate chemical and allergen contamination when allergen-free foods were cooked in transparent polyethylene bags (pack-cooking) in boiled food (for distribution) to provide individualized disaster food support for food allergy sufferers, assuming limited heat sources and drinking water. Residual evaporation migrating from various polyethylene bags was measured through elution tests using food-simulating solvents, following the Japan Positive List (PL) System guidelines. For evacuees with allergies, samples of pack-cooked rice and allergen-free stew wrapped in two layers of polyethylene bags were cooked with a white stew containing allergenic ingredients (wheat, milk, and eggs). Allergenicity was assessed using commercially available enzyme-linked immunosorbent assay (ELISA), western blotting (WB) kits, and polymerase chain reaction (PCR) method. Residual evaporation from all six types of polyethylene bags was below the standard values set by the Japan PL. The protein content derived from each raw material, measured per gram of sampled weight, was significantly lower (<em>p</em> ≤ 0.001) in the pack-cooked meal than in the white stew, with a maximum detected level of 2.5 µg/g for wheat protein in the pack-cooked stew. Thus, the protein content of all pack-cooked meals was below Japan's labeling threshold (10 μg protein per gram of food). A small amount of wheat-, egg- and milk-derived protein was detected in the ELISA test, but no allergens were identified in the WB and PCR. These results suggest that allergen-free meals can be safely prepared using polyethylene bags that can be heated in hot water, even in dishes containing allergens.
