The SBF coating significantly reduced weight loss and maintained higher firmness i.e. with only 7 ± 1.14% weight loss resulted after 9 days compared to a 16.5 ± 0.7% weight loss in uncoated strawberries. It also preserved higher levels of total soluble solids and titratable acidity compared to uncoated strawberries. Additionally, the SBF coating effectively slowed moisture loss, prevented infection, and regulated pH and respiration rate, demonstrating its potential for postharvest preservation of strawberries.</p></div>","PeriodicalId":564,"journal":{"name":"Food Biophysics","volume":"19 4","pages":"1147 - 1156"},"PeriodicalIF":2.8,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11483-024-09889-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142259266","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates the drying kinetics and moisture sorption isotherms of jelly candy. The aim of the study focuses on comparing the effectiveness of conventional models (Courie-GAB-Peleg) and artificial neural networks (ANN) in analyzing the sorption behaviour of jelly candy, specifically when corn stract was added. In addition, the drying characteristics, shrinkage, and storage recommendations of jelly candies were also identified. The static gravimetric method uses a saturated solution of sulfuric acid with 13 (thirteen) different concentrations to condition the water activity (a<sub>w</sub>) in the range of 0.06–0.89 (25–35 °C). In addition, the oven drying processed at a temperature of 40–60 °C with an air speed of 3.6 m/s. The study results show that the final equilibrium moisture content (EMC) of drying has a range of 19.74%w.b-22.02%w.b, and the highest drying rate is 0.11%w.b/min-0.27%w.b/min. At the end of dryng, shrinkage of jelly candy is 22-33% compared to initial conditions. Based on the model accuracy test, it shows that the Peleg model was identified as the best model. The correlation between drying kinetic and moisture sorption was explained with storage recommendations and its recommendation for good jelly candy storage is 24.19%w.b. These storage recommendations were used to determine the appropriate stop of the drying process to minimize drying time.</p></div>","PeriodicalId":564,"journal":{"name":"Food Biophysics","volume":"19 4","pages":"1134 - 1146"},"PeriodicalIF":2.8,"publicationDate":"2024-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142190168","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We found that ice nucleation rates in beef and zucchini were significantly higher than those in broccoli and potato, whereas ice growth was faster in broccoli and potato compared to beef and zucchini. Thus, ice nucleation and ice growth in the foods tested here, were found to be opposing processes.

Potato protein solubility varied with pH, being insoluble at its isoelectric point (pH 5), whereas mushroom powders were insoluble across all pH values. Heating the protein-mushroom hybrids at 90 °C for 30 min promoted denaturation and gelation of the potato proteins. Texture profile analysis showed hybrids were harder and chewier, particularly for Shiitake mushrooms, giving a more meat-like texture. Dynamic shear rheology confirmed the formation of strong, irreversible heat-set gels, and color analysis showed a browner appearance after mushroom addition. Microscopy showed a heterogeneous microstructure due to insoluble mushroom particles in the potato protein matrix.

This research investigates the interaction between waxes and palm stearin in hybrid fat blends. For the oleogels, 150% of the critical gelling concentration of the waxes was used, specifically 6% berry wax (BEW), 1.5% candelilla wax (CLW) and 6% carnauba wax (CRW), all incorporated in rapeseed oil.

It was found that the addition of PS to the wax-based oleogels largely affected the properties on the nano- to macroscale. On the nanoscale, the polymorphic transition from α to β of palm stearin was delayed when adding BEW, while it did not change with the other waxes. On microscale, the high melting CRW acted as a seeding template for the palm stearin in PS-CRW, resulting in the formation of fat crystals that were rich in CRW in the center. For PS-BEW and PS-CLW, it was hypothesized that the fat crystals were the result of co-crystallization.
