Artificial ripening, frequently performed with the use of calcium carbide, speeds up the process but harms fruit and its nutritional value. Spotting unnaturally ripened fruits is crucial for the quality and safety of food, but current models are inefficient or too complicated, especially for diverse fruit varieties. Long-Short-Term Memory (LSTM) as well as Gated Recurrent Unit (GRU) extraction and selection of features techniques are combined using Extended Gradient Boosting (XGBoost) with Convolutional Neural Networks to deal with these challenges. The proposed structure segments fruit thermal pictures employing Saliency Maps to draw attention to relevant areas. LSTM and GRU models are fused to produce multiscale sets of characteristics, allowing the model to record temporal along with geographic characteristics. A Bacterial Foraging Optimizer (BFO) built around variance maximization retains high-density as well as discriminative features during feature selection. A novel Convolutional XGBoost Network (CXGBN) combines CNN's completely connected layers with XGBoost classifications for enhanced efficiency. On Mango as well as Apple data sets, precision, reliability, as well as recall improved 8.3 %, 4.9 %, and 3.4 %. The model efficiently identified artificially ripened fruits, decreasing classifying delays by 6.5 %. This study presents a novel hybrid framework for spotting prematurely ripened fruits using LSTM-GRU fusion and XGBoost CNN. The proposed model outperforms and scales existing methods by solving inefficiencies and using advanced optimization as well as classification techniques. It will be tested for adaptability to other fruit types and real-time applications using low-complexity feature sets along with advanced methods like Q-Learning as well as Auto Encoders that will enhance dynamical performance.
人工催熟,通常使用电石进行,加速了这一过程,但损害了水果及其营养价值。发现不自然成熟的水果对食品的质量和安全至关重要,但目前的模型效率低下或过于复杂,特别是对于多种水果品种。长短期记忆(LSTM)和门控循环单元(GRU)提取和特征选择技术结合使用扩展梯度增强(XGBoost)和卷积神经网络来应对这些挑战。所提出的结构段生成热图像,使用显著性图来引起对相关区域的注意。LSTM和GRU模型融合产生多尺度特征集,使模型能够记录时间和地理特征。围绕方差最大化构建的细菌觅食优化器(BFO)在特征选择过程中保留了高密度特征和判别特征。一种新颖的卷积XGBoost网络(CXGBN)将CNN的完全连接层与XGBoost分类相结合,以提高效率。在芒果和苹果的数据集上,准确率、可靠性和召回率分别提高了8.3 %、4.9 %和3.4 %。该模型有效地识别了人工成熟的水果,减少了6.5 %的分类延迟。本研究提出了一种利用LSTM-GRU融合和XGBoost CNN识别早熟水果的新型杂交框架。该模型通过解决低效率问题和使用先进的优化和分类技术,超越并扩展了现有的方法。它将被测试对其他水果类型和实时应用的适应性,使用低复杂性的特征集以及先进的方法,如Q-Learning和自动编码器,将增强动态性能。

Brazilian papaya production and exports have increased in recent years, and as a phytosanitary requirement, emerging technologies have been introduced into the agricultural chain. Electron beam (E-beam) irradiation has phytosanitary potential for the treatment of fruits, as it is safe and effective in controlling agricultural pests, extending the shelf life of the fruits, and preserving their quality. E-beam irradiation doses of 1, 3, and 5 kGy were applied on 'Golden' papaya fruit, with non-irradiated fruits (0 kGy) used as a control were applied on 'Golden' papaya fruit inoculated with fungi Colletotrichum gloeosporioides and Phoma caricae-papayae to verify if this technology could reduce postharvest diseases from the papaya rot complex. Also, this study evaluated the effects of the same E-beam doses on the postharvest quality of papayas, by analyzing physicochemical characteristics such as titratable acidity (TA), total soluble solids (TSS), Total Phenolic Content (TPC), firmness, and weight loss, as well as enzymatic activity of pectin methylesterase (PME) and polygalacturonase (PG) in the fruit. E-beam irradiation did not affect these variables. A difference was observed among the tested doses on the TA, TSS, TPC, and weight loss with the temperature increase during storage. In the other analysis, PME and PG activity and firmness were not influenced by the irradiation doses. Fruit at the 1 kGy, in general, had similar results as the control ones, this dose also was effective in reducing the growth of C. gloeosporioides and P. caricae-papayae and maintaining the quality of fruit since the doses of 3 and 5 kGy caused injuries to them.
近年来,巴西木瓜的生产和出口有所增加,作为植物检疫要求,新兴技术已被引入农业链。电子束辐照在控制农业害虫、延长水果保质期和保持水果品质方面具有安全有效的应用前景。将1、3和5 kGy的电子束辐照剂量应用于“黄金”番木瓜果实,并将未辐照的果实(0 kGy)作为对照,应用于接种了真菌炭黑菌和番木瓜病菌的“黄金”番木瓜果实,以验证该技术是否可以减少番木瓜腐病复合体的采后病害。此外,本研究还通过分析木瓜果实的可滴定酸度(TA)、总可溶性固形物(TSS)、总酚含量(TPC)、硬度和失重等理化特性,以及果胶甲基酯酶(PME)和聚半乳糖醛酸酶(PG)的酶活性,评估了相同电子束剂量对木瓜采后品质的影响。电子束辐照对这些变量没有影响。在贮藏过程中,随着温度的升高,不同剂量的TSS、TPC、TA和失重量均有差异。在另一项分析中,PME和PG的活性和硬度不受辐照剂量的影响。1 kGy处理的果实总体上与对照效果相似,由于3 kGy和5 kGy处理对gloeosporioides和P. caricae-papayae造成伤害,该剂量也能有效地抑制gloeosporioides和P. caricae-papayae的生长并保持果实品质。

The charring of a whisky barrel is a critical step at the beginning of the whisky ageing process. The extent of barrel charring and its resultant influence on the generation of phenols and esters that alter whisky flavour profiles is yet to be fully explored. In this study, American white oak (Quercus alba) was charred at nine different temperatures, 473–1073 K, and added to both neat ethanol and new make unaged whisky for 500 days. Through the tailoring of the surface area to volume ratio, ageing was focussed over the equivalent of a 250-day maturation period in a full-sized sherry butt, enabling nine chemical species, each associated with a unique flavour profile, to be tracked via regular sampling. The temperature at which the char was formed was not observed to directly alter the tracked flavour congeners, although trends concerning early ethyl ester formation are discussed. Notably, it was found that the presence of a char gradient, arising from the use of a blowtorch, increased the production of ethyl esters, particularly significant during the early stages of the aging process. We believe that additional studies investigating the influence of set heat exposures on char formation could further quantify this effect, enabling the impact of charring on whisky flavour profiles to be further understood.
威士忌桶的炭化是威士忌陈酿过程开始的关键步骤。橡木桶炭化的程度及其对产生改变威士忌风味的酚类和酯类物质的影响还有待进一步研究。在这项研究中,美国白橡木(Quercus alba)在9种不同的温度(473-1073 K)下烧焦,并加入纯乙醇和新酿造的未陈酿威士忌中500天。通过对表面积与体积比的调整,陈酿过程集中在相当于一个全尺寸雪利酒臀250天的成熟期上,通过定期取样,可以跟踪九种化学物质,每种化学物质都有独特的风味。虽然讨论了早期乙基酯形成的趋势,但没有观察到形成焦炭的温度直接改变所追踪的风味同系物。值得注意的是,研究发现,由于使用喷灯而产生的焦炭梯度的存在,增加了乙酯的产量,在陈化过程的早期阶段尤其显著。我们相信,进一步的研究可以进一步量化这种影响,使炭化对威士忌风味的影响得到进一步的了解。

Background

The physical properties of resistant starch (RS) are similar to those of dietary fiber; thus, RS is often added to food products to provide the same health benefits as dietary fiber.

Methods

In this study, four types of RS were mixed with wheat flour, and gels were prepared. RS-2, high amylose corn starch (HACS), was used alongside three types of RS-4: phosphate cross-linked tapioca starch (XLTS) and low- and high-hydroxypropylated phosphate tapioca starch (LHTS and HHTS, respectively). The flour suspension (16.7 w/w %) consisted of a mixture of medium wheat flour (1:1 mixture of low- and high-gluten wheat flour) and RS, combined in a 95:5 ratio. The suspension was heated at either 90 or 120 °C. The control sample consisted of wheat flour only. Compressive analysis, texture analysis, microscopic observations, RS measurements, and thermal properties analysis were performed.

Results

The gel made with HACS was soft after heating at 90 °C, and this gel showed the highest RS content. Additionally, the control and HACS gels had increased RS content when heated at 120 °C. In contrast, while the physical properties of the RS-4 mixed gels (XLTS, LHTS, and HHTS) changed upon heating, the RS content did not increase in the gels heated at 120 °C. Therefore, the RS-4 mixed gels may inhibit wheat starch aging during retort cooking.

Conclusions

These results indicate that mixing HACS into flour is the most effective way to increase the RS content in a water-dispersed flour system with high-moisture content, with higher heating temperatures facilitating this process.
抗性淀粉(RS)的物理性质与膳食纤维相似;因此,RS经常被添加到食品中,以提供与膳食纤维相同的健康益处。方法将4种RS与小麦粉混合,制备凝胶。高直链玉米淀粉(HACS) RS-2与三种类型的RS-4:磷酸交联木薯淀粉(XLTS)和低羟丙基磷酸木薯淀粉(LHTS)和高羟丙基磷酸木薯淀粉(HHTS)一起使用。面粉悬浮液(16.7 w/w %)由中筋小麦粉(低筋和高筋小麦粉1:1混合)和RS以95:5的比例混合而成。悬浮液在90或120°C下加热。对照样品仅由小麦粉组成。进行了压缩分析、织构分析、微观观察、RS测量和热性能分析。结果用HACS制备的凝胶经90℃加热后呈柔软状,RS含量最高。另外,对照组和HACS凝胶在120℃下加热时RS含量增加。相比之下,RS-4混合凝胶(XLTS、LHTS和HHTS)的物理性质在加热后发生变化,而在120℃加热时RS含量没有增加。因此,RS-4混合凝胶可以抑制小麦淀粉在蒸煮过程中的老化。结论在高含水率的水分散面粉体系中,在面粉中加入HACS是提高RS含量最有效的方法,而较高的加热温度有利于提高RS含量。

Jun tea, a non-alcoholic functional drink, can confer physiological and neurological benefits to human beings. Various phenolic components in Jun tea are degraded in an acidic condition by the enzymatic activity of bacteria and yeast present in the tea fungal association. Therefore, this study aimed to explore the efficacy of ultrasonication (750 W power; 27 kHz frequency) on the physicochemical, microbiological and rheological properties of Jun tea with variation in treatment time (20–40 min). The total phenolic content (TPC), antioxidant activity, pH, and cloud stability of Jun tea were significantly (p < 0.05) increased after the ultrasonic treatment, which was further confirmed by the FTIR spectra analysis. In contrast, prolonged exposure to ultrasound resulted in a significant declination of alcohol content, whiteness index, plate count, and apparent viscosity of Jun tea. The outcomes of this study explore the application of low-cost non-thermal technology (ultrasound technique) in fermented beverage industries. This product replaces the extensive use of commercially available carbonated beverages.
君茶是一种不含酒精的功能性饮料,对人体的生理和神经系统都有好处。在酸性条件下,茶真菌群落中存在的细菌和酵母菌的酶活性降解了君茶中的各种酚类成分。因此,本研究旨在探讨超声(750 W功率;27 kHz频率)对君茶理化、微生物学和流变性能随处理时间(20-40 min)变化的影响。超声处理后的君茶总酚含量(TPC)、抗氧化活性、pH值和云稳定性显著提高(p <; 0.05),FTIR光谱分析进一步证实了这一点。相比之下,长时间暴露于超声波导致君茶的酒精含量、白度指数、平板计数和表观粘度显著下降。本研究探讨了低成本的非热技术(超声技术)在发酵饮料工业中的应用。该产品取代了市售碳酸饮料的广泛使用。

Wheat is one of the most important cereal crops and a critical ingredient in a wide range of ready-to-eat products, such as bread, noodles, cakes, and snacks, due to its favorable sensory attributes and processing properties. Extrusion, a process commonly used in the food industry, has proven effective in enhancing the nutritional value and functionality of wheat-based products by precisely controlling processing parameters. In this review, we explore the effects that extrusion process parameters have on the structural, functional, and physicochemical properties (e.g., expansion ratio, water absorption index, water solubility index, texture, viscosity, and digestibility) of wheat-based products. We also discuss specific applications of extruded wheat products. The findings of this review highlight how including an extrusion process can improve product quality and advance wheat-based product development in the food industry.

In our previous studies, ultrasonic washing was proven to induce phenolic biosynthesis in fresh-cut red cabbages; however, the related regulatory mechanisms remain unclear. In response, this study investigates the mechanisms of phenolic biosynthesis in fresh-cut red cabbages under ultrasound stress from the perspective of energy metabolism. The effects of exogenous adenosine triphosphate (ATP) and 2,4-dinitrophenol (DNP) on the phenolic biosynthesis and antioxidant enzymes of fresh-cut red cabbages were also studied. The results show that ultrasound treatment induces the activities of adenosine triphosphatases (ATPase), succinate dehydrogenase (SDH), and cytochrome oxidase (CCO), thus maintaining the high-energy status of fresh-cut red cabbages during storage, primarily characterized by an increase in ATP content and energy charge (EC). The high-energy status is beneficial for providing energy to the biosynthesis of phenolic compounds. In addition, the phenolic content, as well as the activities of phenylalanine ammonia-lyase (PAL), cinnamate-4-hydroxylase (C4H), 4-coumarate-CoA ligase (4CL), superoxide dismutase (SOD), catalase (CAT), and ascorbate peroxidase (APX), was increased in the fresh-cut red cabbages after ATP treatment, whereas DNP treatment showed the opposite effect. The results indicate that energy plays an essential role in regulating the antioxidant systems of fresh-cut red cabbages. The energy enhancement induced by ultrasound treatment is a key reason to promote the biosynthesis of non-enzymatic antioxidant–phenolic compounds and enhancing antioxidant enzyme activities. Therefore, the increase in energy levels induced by ultrasonic washing is closely related to the accumulation of phenolic compounds. Positive energy regulation could be a potential mechanism to improve the nutritive value of fruits and vegetables subjected to ultrasonic washing.
在我们之前的研究中,超声波洗涤被证明可以诱导鲜切红甘蓝的酚类生物合成;然而,相关的监管机制尚不清楚。为此,本研究从能量代谢的角度探讨超声胁迫下鲜切红甘蓝酚类物质的生物合成机制。研究了外源三磷酸腺苷(ATP)和2,4-二硝基酚(DNP)对鲜切红甘蓝酚类生物合成和抗氧化酶的影响。结果表明:超声处理可诱导三磷酸腺苷酶(ATPase)、琥珀酸脱氢酶(SDH)和细胞色素氧化酶(CCO)活性,维持鲜切红甘蓝贮藏期间的高能状态,主要表现为ATP含量和能量电荷(EC)的增加。这种高能状态有利于为酚类化合物的生物合成提供能量。此外,ATP处理提高了鲜切红甘蓝酚类物质含量,并提高了苯丙氨酸解氨酶(PAL)、肉桂酸-4-羟化酶(C4H)、4-香豆酸-辅酶a连接酶(4CL)、超氧化物歧化酶(SOD)、过氧化氢酶(CAT)和抗坏血酸过氧化物酶(APX)活性,而DNP处理则相反。结果表明,能量在调节鲜切红甘蓝抗氧化系统中起重要作用。超声处理诱导的能量增强是促进非酶抗氧化酚类化合物生物合成和增强抗氧化酶活性的关键原因。因此,超声波洗涤引起的能级升高与酚类化合物的积累密切相关。正能量调节可能是提高超声清洗果蔬营养价值的潜在机制。

Microwave heating is one of the most significant food-related physical-field processing technologies, possessing wide application potential in the food industry and for scientific research. This study explores microwave heating characteristics by conducting Multiphysics numerical simulations within a single-mode microwave system, emphasizing the impact of solvent type and volume on the heating rate, temperature profile, and distribution of the electric field and power dissipation density. In addition, the study examined the microwave-induced aggregation behavior of myofibrillar proteins (MPs) in diverse monovalent salt solvents by employing an established heating protocol. Results indicate that both the volume and type of solvent influence the microwave heating rate considerably. Specifically, volumes of 2 and 3 mL exhibited significantly higher rates than those of 1 and 4 mL under the test conditions, and these alterations were relatively consistent with the observed distributions of the electric field and power dissipation density. Simulations and measurements disclosed notable temperature gradients within the heating system, which were also affected by the solvent volume and type. Abnormal convection led to increased temperatures in the upper solution layers, and this abnormal convection-induced higher temperature could affect the experimental outcomes in scientific research. Using the aggregation behavior of MPs as an example, we also demonstrated the crucial importance of selecting appropriate heating volumes in single-mode microwave systems. These findings offer a theoretical basis for comprehending microwave-heating processes in single-mode reactors and clarify the common microwave-specific effects encountered in laboratory settings.
微波加热是一种重要的食品物理场加工技术,在食品工业和科学研究中具有广泛的应用潜力。本研究通过在单模微波系统中进行多物理场数值模拟,探讨了微波加热特性,强调了溶剂类型和体积对加热速率、温度分布、电场分布和功耗密度的影响。此外,该研究通过采用既定的加热方案,检测了微波诱导的肌纤维蛋白(MPs)在不同的一价盐溶剂中的聚集行为。结果表明,溶剂的体积和种类对微波加热速率有较大影响。在实验条件下,2和3 mL的体积表现出明显高于1和4 mL的体积,这种变化与观测到的电场分布和功耗密度分布相对一致。模拟和测量结果表明,加热系统内存在显著的温度梯度,温度梯度也受溶剂体积和类型的影响。对流异常导致上层溶液温度升高,对流异常引起的温度升高会影响科学研究中的实验结果。以MPs的聚集行为为例,我们也证明了在单模微波系统中选择合适的加热体积的重要性。这些发现为理解单模反应堆中的微波加热过程提供了理论基础,并澄清了在实验室环境中遇到的常见微波特异性效应。

Infrared (IR) heating technology represents a cutting-edge thermal technology in food processing, offering energy-efficient and effective solutions for various unit operations such as blanching, microbial decontamination, peeling, roasting, and thawing. Recent advancements in IR heating have highlighted its advantages over conventional methods, including short processing time, uniform heating and product temperature, superior quality of products, low energy consumption, high heat transfer rate, high energy efficiency, ease of control, compact equipment and eco-friendliness over the conventional heating systems. Considering these merits, IR has found several applications in food processing with increased interest and research in the last decade. Thus, this review discusses recent studies and technological advancements in IR heating, addressing the benefits, limitations, and challenges of its implementation across different food processing applications. In addition, it explores the synergistic utilization of IR radiation when combined with other novel technologies by assessing their combined impact on process efficiency, energy savings, and food quality. The findings of this study showed that in blanching, IR heating has shown potential to reduce nutrient loss and preserve sensory quality, enhancing the retention of vitamins and minerals. For microbial decontamination, it provides a non-chemical approach to pathogen reduction, minimizing foodborne risks while preserving product quality. In peeling applications, IR heating can achieve efficient removal of skin with minimal waste and damage to the edible portion, making it an eco-friendly option. When used for roasting, it contributes to the development of desirable colour, flavor, and texture attributes. Finally, in thawing applications, IR technology provides faster and more uniform heating, reducing drip loss and improving product quality. From the foregoing, it was established that the adoption of IR heating technology in food processing represents a significant advancement in enhancing product quality and process efficiency across the various applications. Moreover, combining IR heating with other novel food processing technologies further improved process efficiency, enhanced energy savings, and preserved or even boosted food quality. Further research on optimization, process modelling, and the integration of IR heating with other technologies could expand its applicability and effectiveness, paving the way for more sustainable and high-quality food processing solutions.
