Heat is generally employed as a drying agent in traditional thermal drying methods. This involves a high energy cost and significantly reduces the nutritional quality of vegetable products. This study investigates an unconventional, non-thermal drying method for pomegranate arils (PA). It is based on the use of selective molecular sieves for water molecules. This merely permits the extraction of water without compromising the other components that the fruit still contains. Compared to other dehydration techniques, this drying method uses less energy. It consumes 6.5 kWh of energy to take out 1 l of water including energy consumption for the regeneration of molecular sieves, whereas lyophilization and thermal drying procedures require 19.5 kWh and 8 kWh of energy to remove 1 l of water, respectively. Despite that, there is a lack of previous research on drying pomegranate arils using molecular sieves. Drying process studies were conducted on several characteristics, including water activity, water content, color, hardness, and size variation. It has been also investigated how pretreatments such as freezing and osmotic dehydration enhance drying. Using freezing pretreatment, the time of the drying process was reduced from 34 to 10 h, resulting in a final normalized water content (NWC) of 22.23 ± 0.75%. According to the osmotic dehydration pretreatment (OD), water lost (WL) and solid gain (SG) stabilized with values of 42.38% and 0.38% after 300 min of drying.

By combining the spectral feature information of each sensitive band and using the method of transfer entropy, the study analyzed the information flow between physiological and biochemical indicators and spectral characteristics, unveiling the mechanism behind the spectral feature evolution in damaged apple areas. The conclusions are as follows: (1) The evolution of spectral characteristics within the 650–734 nm band is related to browning and chlorophyll degradation processes in the damaged areas, while the evolution of spectral characteristics within the 850–970 nm band is related to changes in the water content of the damaged areas. Additionally, the evolution of spectral characteristics within the 1255–1314 nm band is related to temperature changes in the damaged areas. (2) The effectiveness of different spectral characteristics in characterizing the extent of damage varies. From the perspective of the average transfer entropy value <span>(overline{T })</span> and the maximum entropy value <i>TE</i><sub><i>max</i></sub>, the spectral characteristic <i>tanθ</i> has a significant advantage. In terms of the time dimension, the spectral characteristic <i>tanθ</i> has an advantage in characterizing damage in the early stages of apple damage (0–60 min), while the spectral characteristic <span>(overline{R })</span> is more suitable after 60–90 min of damage. (3) Using the significance coefficient constructed from transfer entropy as an indicator and analyzing from the perspective of information transfer, the color parameters related to browning in the flesh area and the degradation of chlorophyll in the peel area are the main driving factors for spectral curve changes.

The polylactic acid (PLA) film containing acid-etched HNTs loaded with OEO (consisting 2.5% acid-etched HNTs and 5% OEO) was prepared through melt extrusion casting method. The loading capacity of OEO in HNTs increased from 6.8 to 23.2% after acid etching treatment. The addition of acid-etched HNTs promoted the dispersion of OEO in the PLA matrix. The Fourier transform infrared spectroscopy showed the interactions among OEO, acid-etched HNTs, and PLA via hydrogen bonds. The PLA films added with OEO or acid-etched HNTs loaded with OEO both exhibited excellent anti-ultraviolet property. Compared with the PLA film containing OEO only, the film containing OEO and acid-etched HNTs exhibited lower tensile strength and elongation at break, achieved slower release of OEO in food simulant (10% ethanol), and showed lower antibacterial activity, which was closely related to their release behavior. However, there were no significant differences in oxygen and water vapor permeability between these two films.

The results showed that the film containing OEO and acid-etched HNTs exhibited the best maintenance for spinach quality by inhibiting its respiration rate, weight loss, browning, and microbial growth.

The increased elastic behavior led to the formation of a bead-on-string morphology and a higher average diameter. The thermal stability of the loaded nanofibers was diminished by the presence of incorporated polyphenolic extract. Under simulated gastrointestinal conditions, a sustained release of total phenolic content from the delivery systems was achieved. According to the FTIR spectra, this is mainly due to the efficient interplay of hydrogen and hydrophobic interactions with the polyphenols within the polysaccharide-phospholipid-polypeptide structure.

Subsequently, liquefaction was conducted using α-amylase (AMY), followed by saccharification employing amyloglucosidase (AMG) and pullulanase.

Achieving this requires an understanding of the most critical factors in product quality to predict shelf life. Broccoli has been chosen to model this as it is consumed worldwide. To simulate consumer conditions, broccoli heads were purchased in bulk from a local supermarket and stored (in a disposable, compostable bag) at four storage temperatures (3, 5, 7, and 12 ºC) for 13 days. Broccoli quality was evaluated using five factors: weight loss, vitamin C content, total phenolic content, chlorophyll content, and consumer acceptability. Individual shelf-life estimates were calculated for each factor independently using kinetic models and adequate threshold values. The product’s shelf life was obtained by combining the individual estimates; consumer acceptability was noted as being the most relevant criterion at any temperature, followed by vitamin C content or weight loss depending on the storage temperature. However, the effect of temperature was nonlinear; variations within the 3–5 ºC range had little impact on shelf life (13–14 days), whereas an increase to 7 ºC would cause a significant reduction in shelf life (9 days). Hence, according to the fitted models, it is particularly important that the temperature of refrigerated broccoli is closely controlled within the range of 3 to 5 ºC. This information is highly relevant to the industry, supermarkets, and the end consumer, as it emphasizes that temperature control of broccoli is essential to ensure the quality of the product throughout its shelf life, helping to reduce food waste.</p>","PeriodicalId":562,"journal":{"name":"Food and Bioprocess Technology","volume":"85 1","pages":""},"PeriodicalIF":5.6,"publicationDate":"2024-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141742495","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
