“Foam container + ice pack” is a common packaging form for e-commerce logistics of litchis. However, there are numerous factors affecting the temperature variation under this mode, making it difficult to control and litchi quality during process. In order explore impact scheme on environment in litchis “foam process, paper takes number packs, terminal pre-cooling litchis, weight whether use aluminum foil insulating film as variable study rules these EPS (Expanded Polystyrene) foam temperature, total fruit pericarp, marketable rate. The experimental results show following trends: has significant daily average layer; 15 °C group first day second 5.00 2.78 higher than that 5 group, respectively. Moreover, treatment, growth rate pericarp fungi relatively fast, which could reach 3.87 Lg (CFU/g) day. Increasing amount maintain lower environment, but will cause relative conductivity increasing 4.12% compared with groups no increasing. packs significantly reduce decline soluble solids two days. research expected provide certain reference assurance formulation long-distance transportation strategies perishable agricultural products.

Optimizing ventilated packaging design for strawberries: Assessing the impact on fruit quality from farm to retailer using physics-based modeling

Postharvest Biology and Technology, Journal Year: 2024, Volume and Issue: 214, P. 112949 - 112949

Amongst fruits and vegetables, strawberries (Fragaria × ananassa) are one of the most perishable products. Consequently, it is challenging to maintain their quality until they reach consumer. Therefore, keeping optimal hygrothermal conditions around berries from farm consumer crucial preserving them avoiding food loss. Using ventilated packaging design an established way address this technological, economic, environmental problem. Until now, strawberry often designed using a trial-and-error approach, multitude designs exist. Ideally, should be in such that provides best preservation fruit all retailer. This since change significantly along supply chain. In study, we use physics-based modeling evaluate new regard cooling performance, risk condensation, mass loss, respiration-driven shelf life assess performance whole post-harvest export chain Spain Switzerland. Twelve for with existing newly-designed vent hole configurations were investigated. Simulations quantified how physiologically hygrothermally evolve inside these packages Implementing appropriate ventilation open-and top-sealed trays can help minimize losses As commonly known, cool faster better-ventilated than unventilated trays, condensation-based time wetness could reduced by 45% adding additional holes tray. The height secondary packaging, total opening area (TOA), size, placement vents have substantial influence on packaging. We recommend TOA between 5.5% 7% diameter 5 12 mm. Also, evenly distributed. However, there always trade-off design: condensation comes higher loss strawberries. Strawberry models enabled unique insight into evolution visualized spatial distribution package.

TwinLab: a framework for data-efficient training of non-intrusive reduced-order models for digital twins

Engineering Computations, Journal Year: 2024, Volume and Issue: unknown

Published: July 4, 2024

Purpose: Simulation-based digital twins represent an effort to provide high-accuracy real-time insights into operational physical processes. However, the computation time of many multi-physical simulation models is far from real-time. It might even exceed sensible frames produce sufficient data for training data-driven reduced-order models. This study presents TwinLab, a framework data-efficient, yet accurate neural-ODE type with only two sets. Design/methodology/approach: Correlations between test errors and distinct features corresponding are investigated. Having found single best sets training, second set sought help similarity error measures enrich process effectively. Findings: Adding suitable in reduces by up 49% compared base model trained one set. Such should at least yield good on its own exhibit higher levels dissimilarity regarding respective excitation signal. Moreover, have elevated The relative series ranges 0.18% 0.49%. Prediction speed-ups factor 36,000 observed. Originality: proposed computational facilitates automated, data-efficient extraction non-intrusive existing models, independent software.

Biodegradable Coatings Based on Cassava Starch and Poly(Vinyl Alcohol): Potential Application for Prolonging the Shelf Life of Strawberries (Fragaria ananassa) cv. San Andreas

ACS Food Science & Technology, Journal Year: 2024, Volume and Issue: 4(2), P. 365 - 372

Published: Jan. 12, 2024

Biodegradable edible coatings have become a viable alternative for preserving fruits such as strawberries with high degree of perishability, extending their postharvest shelf life. The study aimed to develop biodegradable coating based on cassava starch and poly(vinyl alcohol) extend the life at 25 ± 5 °C, since no formulations or studies were found this storage temperature. formation composite was confirmed by signals in FTIR spectra. results demonstrate that presence soybean oil lecithin promotes rearrangement polymer bonds, ensuring availability hydroxyls. Thus, formulation B obtained hydrophobic surface, justified lower moisture content, water solubility, vapor permeability. new material applied fresh strawberries, delaying senescence process °C 105% compared control sample.
