Sensors embedded in smart food packaging materials are commonly synthetic dyes that are known to be toxic and carcinogenic. In this study, biodegradable films were fabricated by employing pH-sensitive anthocyanin extract from <i>Passiflora suberosa</i>, an unexplored source of natural and safer bio-based sensors. Anthocyanin-rich extract of <i>P. suberosa</i> showed remarkable color changes from red (pH 1–3) and eventually turned to pink (pH 4–6), purple (pH 8–10) and green/yellow (pH 11–13) upon contact with different buffer solutions. The films were prepared using a solvent casting process by incorporating different concentrations of <i>P. suberosa</i> anthocyanin (PSA) extracts. Fourier-transform infrared spectroscopy (FT-IR) and Scanning electron microscopy (SEM) analysis were used to study the chemical composition and the surface morphology of the PSA films. The films showed a decreasing trend of moisture content, from 39.5% to 33.2%, upon the addition of increasing concentrations of PSA extracts. The color changes and pH response of the bioactive film were evaluated with a series of standard buffer solutions (pH 3, 5, 7, 9, and 11). The film showed excellent pH-sensitivity properties (visible response within the first 10 s) and good color variations, from red to green, upon testing with the chosen pH buffer. The response surface analysis predicted that maximum color change (Δ<i>E</i>) for the PSA film was 5.38 and could be obtained with the employment of 0.5% of PSA concentration in pH 3 buffer solution. Therefore, incorporating the extract from <i>P. suberosa</i> into the sago starch film matrices equipped the film with excellent pH-responsive characteristics for a new potential formulation of smart food packaging film.</p>\u0000 </div>","PeriodicalId":15932,"journal":{"name":"Journal of Food Process Engineering","volume":"48 3","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143707335","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The texture of almond slices became harder, while the texture of other dried nuts remained unchanged. There were no significant alterations in the original color, flavor, or appearance of the dried nuts. The CP treatment significantly reduced the levels of toxin-releasing aflatoxins in the dried nuts. The moisture content, which is linked to microbial activity, was significantly decreased.

Legumes have been offering significant nutritional advantages and making them a superior choice for meat substitutes due to their advantages in protein quality. Legume composites such as pea protein isolate (PPI) and isolated soy protein (ISP) and vital wheat gluten combine with other ingredients to create a fibrous texture. A mixture design approach was employed to optimize the formulation with freeze structuring methodology; machine learning (ML) models were integrated to predict the textural and sensory properties of the resulting meat analogues. The final samples were tested for textural, water activity, sensory properties, and water activity, which is used to validate the consistency of the experimental formulations. The optimized formulation, consisting of 18.9% PPI, 12.6% ISP, and 8.5% VWG, exhibited a hardness of 815.587 N, springiness of 0.845 mm, overall acceptability of 8.7, and water activity of 0.887. Integrating five ML algorithms for built-in feature selection and classification mechanisms predicted the desired properties. The predicted values from the ML models closely matched the experimental results, demonstrating the potential of this approach with a negligible amount of difference in experimental values. Among the ML models tested, Gradient Boosting provided the best prediction for hardness (RMSE = 24.698, <i>R</i><sup>2</sup> = 0.986), AdaBoost performed best for springiness (RMSE = 0.019, <i>R</i><sup>2</sup> = 0.940) and overall acceptability (RMSE = 0.284, <i>R</i><sup>2</sup> = 0.904), while XGBoost showed the highest accuracy for water activity prediction (RMSE = 0.002, <i>R</i><sup>2</sup> = 0.985).

The results indicated that the parameters extracted using the impedance spectrum can reflect the state of agricultural food, and the dimension, heterogeneity, detection location, and ambient temperature of samples substantially influence measurement precision. However, the following two problems limit further application: the extraction of electrical parameters of different states and the individual differences in samples. Extraction methods include the equivalent circuit model, characteristic frequency, and Cole-Cole function. Because currents of different frequencies flow through tissues in different routes, the characteristic frequency method can express cell information changes. The fusion parameters representing the product's quality can be obtained using proper selected-frequency extraction. Eliminating the individual heterogeneity of agricultural products is the remaining technical limitation. A preliminary study shows characteristic points on the EIS curve could reduce individual differences.

Optimal conditions for the OMD integrated reactor (R-Batch+OMD) were established using response surface methodology, yielding a temperature of 36.7°C, an enzyme concentration of 6.0 U g LS<sup>−1</sup>, and a lactose concentration of 32°Brix (% wt/wt).

The objective of this study was to investigate the kinetic data of these compounds simultaneously throughout conventional solvent extraction (CSE) and ultrasound-assisted extraction (UAE) processes using a real-time spectral monitoring system and to determine the effects of two different extraction methods on the extraction efficiency and end point. In this context, the continuous kinetic data obtained were analyzed and modeled with various mathematical model equations. The results revealed that the highest total phenol content was measured as 4.20 mg GaEq g<sup>−1</sup> fw, total flavonoid content was measured as 3.88 QEq g<sup>−1</sup> fw, and total anthocyanin content was measured as 5.15 mg CynEq g<sup>−1</sup> fw under all conditions tested. Moreover, the UAE method demonstrated superior efficiency in quickly extracting these components and reaching equilibrium. Among the six kinetic models, the modified Peleg model was determined to be the most suitable for both CSE and UAE.
