However, whether the combination of two stresses can further enhance their resistance warrants exploration. This study examined the effects of cross stress on the resistance of the <i>Lactiplantibacillus plantarum</i> LIP-1 strain against freeze-drying. Compared with oxygen or cold stress alone, cross stress increased the post-freeze-drying survival rate of <i>L. plantarum</i> LIP-1 to 84.98% (<i>P</i> < 0.05). After 8 weeks of room-temperature storage, the count of live bacteria could still be maintained at 6.27 × 10<sup>9</sup> CFU/g. Mechanistic analyses revealed that the strain treated with cross stress could synthesize more protective biofilms and surface proteins, which significantly reduced cell wall damage. Furthermore, owing to the combined effect of two single stresses, cross stress could enhance the strain’s antioxidant capacity, reduce the production of reactive oxygen species, inhibit the oxidation of fatty acids in the cell membrane, and maintain the integrity and fluidity of the cell membrane. In addition, cross stress treatment increased the intracellular pH, effectively reducing the degree of DNA damage. These factors significantly improved the survival rate of <i>L. plantarum</i> LIP-1 after freeze-drying.</p>","PeriodicalId":562,"journal":{"name":"Food and Bioprocess Technology","volume":"21 1","pages":""},"PeriodicalIF":5.6,"publicationDate":"2024-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141742685","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}

Several artificial intelligence applications have been implemented for microbiological safety assessment, predictive modelling, and optimization of pasteurization processes that aim to reduce failure costs due to recall incidents and the necessity for costly quality assurance control measures.

In the present study, laser light scattering density (LSD) analysis was applied to study the effect of cell size distribution percentages on fruit mechanics, considering three growth stages and added variance by foliar spray application of Ca, N, and Ca-N. The growth rate k considering cell size range 300–450 µm was enhanced in N compared to Ca treatment with 0.8 and 0.5, respectively. Comparison of cell sizes and mechanical fruit tissue properties reveals a strong effect of cell size on fruit mechanics. Based on cell size data, the particles in discrete element models (DEM) were established, applying a simple contact model of Hertz-Mindlin to test the effect of LSD data input, when simulating the compression peak force of strawberry tissue. Comparing measured compression data and DEM simulation, the mean square error was reduced, e.g., for Ca group of over-ripe fruit, from 9.6 to 6.5% when LSD percentages of cell size distribution were considered. Concluding, the newly available cell size distribution data provide valuable information on fruit growth and enable the simulation of fruit tissue compression under varying environmental growth conditions.

The aim of this study was to evaluate the antioxidant and ACE-inhibitory activities of peptide fractions from triggerfish (<i>Balistes capriscus</i>) processing coproducts. Protein fractions were extracted from fish viscera and hydrolyzed using papain (HP), bromelain (HB), and trypsin (HT) (3% p.p<sup>−1</sup>, 6 h). The molecular mass distribution of soluble protein extract (SPE) and hydrolysate was determined by gel filtration chromatography. Samples were extracted and ultra-filtrated (> 100 MWCO, 30–100, 10–30 and < 10 MWCO). Antioxidant activity of fractions was evaluated, and fraction SPE4 (< 10 MWCO) showed the highest value of Trolox Equivalent Antioxidant Capacity—TEAC (10,157.7 µmol Trolox. g<sup>−1</sup>) and Ferric Reducing Antioxidant Power—FRAP (1588.71 µmol FeSO<sub>4</sub>. g<sup>−1</sup>).

F1 fraction showed the highest value for TEAC capacity (8839.04 µmol Trolox. g<sup>−1</sup>) and FRAP (1749.94 µmol FeSO<sub>4</sub>. g<sup>−1</sup>).

Amino acid sequencing of peptides indicated the presence of hydrophobic amino acids such as leucine (L), valine (V), phenylalanine (F), and alanine (A) in the C-terminal position, which contributed to antioxidant activity of peptides fractions. ACE inhibitory capacity was influenced by the presence of arginine (R) and lysine (K) positively charged in the C-terminal.
