This review systematically analyzes the core physical mechanisms of LNSF — cavitation, atomization, heat transfer, and ice crystal dynamics — highlighting key controlling parameters including cavitation number (<i>σ</i>), Weber number (<i>We</i>), Ohnesorge number (<i>Oh</i>), and Reynolds number (<i>Re</i>). The effects of flow properties, nozzle geometry, ambient conditions, and surface characteristics are examined in detail. We also explore digital innovations that enable a shift from rapid to precision freezing, including multimodal sensing, predictive modeling, and adaptive control. Applications across aquatic products, fruits and vegetables, edible fungi, starch-based products, and biological tissues are discussed, emphasizing how cross-scale coupling between flow dynamics and thermophysical behavior influences freezing efficiency, ice morphology, and product quality.

This review explores the application of AI across pre- and postharvest stages using spectroscopic (e.g., NIR, THz), imaging (e.g., hyperspectral, X-ray), and sensor-based systems (e.g., electronic nose).

Data science tools (keyword co-occurrence, thematic maps, and multiple correspondence analysis) were applied to identify trends, emerging themes, and conceptual relationships. The analysis revealed two main lines: one focused on complex emulsions and the other on vegetable formulations optimized with hydrocolloids. The rheological properties and the type of protein isolate prove to be fundamental axes in the formulation of food inks. It was identified that the type of ingredient (hydrocolloids, lipids, enzymes) and their interaction with proteins directly influence the viscosity, elasticity, extrudability, and shape retention capacity of the inks. Additionally, post-processing methods (baking, microwaving, and enzyme treatment) have a significant impact on the texture, stability, and overall acceptance of the final product. From experimental and literature data, unsupervised classification models (K-means, GMM, hierarchical clustering) based on rheological variables (G′, G″, tan δ) were developed, which allowed the identification of three groups of inks with differential behavior, associated with printing parameters such as nozzle diameter, speed, and filling percentage. Visualization by PCA showed how these properties impact extrusion and structural fidelity.

Neglected and underutilised vegetables (NUVs) cultivated in arid ecosystems are climate-resilient, highly nutritious, and possess immense potential to combat malnutrition and hidden hunger. However, NUVs poses short shelf life, and the absence of suitable post-harvest management and storage systems leads to 20–40% losses, exacerbating the food crisis. Conventional drying methods rely on fossil fuels or grid-dependent energy, which are scarce and unaffordable in remote arid areas, resulting in continued reliance on open-sun drying (OSD), which is associated with prolonged drying periods, uncontrolled thermal exposure, fluctuating humidity, contamination risks, and significant nutrient degradation. This review critically evaluates controlled solar drying systems capable of regulating key parameters to enhance drying kinetics and process stability. Under arid conditions, these systems typically maintain drying air temperatures of 45–75 °C and achieve effective moisture diffusivity in the range of 10⁻⁹–10⁻⁷ m²/s, reducing drying time by 30–60% compared to open-sun drying while improving moisture uniformity, nutrient retention, and microbial safety. Beyond technical performance, controlled solar drying contributes to shelf-life extension, value addition, rural income generation, and low-carbon food processing. Unlike existing solar drying system reviews that primarily focus on commercially cultivated crops, this review uniquely synthesizes controlled solar drying for NUVs in arid ecosystems, integrating performance metrics, quality preservation, and sustainability within a broader food security framework.</p>\u0000 </div>","PeriodicalId":565,"journal":{"name":"Food Engineering Reviews","volume":"18 2","pages":""},"PeriodicalIF":7.6,"publicationDate":"2026-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147607147","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}
