Processing Of Products Research Articles

Influence of (ultra-)processing methods on aquatic proteins and product quality.

Aquatic products are a high-quality source of protein for humans, and the changes in protein during aquatic product processing are crucial for nutritional value, product performance, and consumer health. With the advancement of science and technology, aquatic product processing methods have become increasingly diverse. In addition to traditional methods such as thermal processing (steaming, roasting, and frying) and pickling, emerging non-thermal processing technologies, such as high pressure, ultrasound, and irradiation, are also being applied. During (ultra-)processing, aquatic products undergo complex biochemical reactions, among which protein oxidation significantly affects the quality of aquatic products. Protein oxidation can alter the molecular structure of proteins, thereby changing their functional properties and ultimately impacting product quality. This paper primarily explored the effects of protein changes under different processing methods on aquatic product quality and human health, as well as techniques for controlling protein oxidation. It aims to provide a theoretical basis for selecting appropriate processing methods, improving aquatic product quality, and controlling protein oxidation in aquatic products, and to offer scientific guidance for practical production.

ANÁLISE DE RISCOS NA PRODUÇÃO DE FRIGORÍFICOS: ESTRATÉGIAS PARA PREVENÇÃO E CONTROLE

This paper is a scientific article whose theme is the analysis of risks in the production of meatpacking plants: strategies for prevention and control. In this environment, workers face physical risks, biological risks and risks of accidents. This is because, in meatpacking plants, we find places where the temperature is extremely low (usually below 0º). Therefore, the function of the PPE provided is to provide safety to avoid humidity, low temperatures, noise, injuries caused by sharp instruments and biological contamination. What strategies should be adopted to prevent and control the occurrence of accidents and/or the spread of diseases in the production line of meatpacking plants, based on risk analysis? The general objective is: to describe what risk management is as well as the best way to apply it in a meatpacking plant to prevent accidents and control occupational diseases. The specific objectives are: to characterize what risk analysis and management are in a meatpacking plant; to present the main characteristics of the production environment as well as the main precautions that should be taken to ensure the physical integrity of the worker; describe the guidelines set out in NR-32 and its determinations for occupational health and safety, especially in companies that work with the slaughter and processing of meat and meat products. The methodology used will be a descriptive and exploratory literature review

Unraveling the molecular interactions and antioxidant mechanism of β-lactoglobulin with aloe’s hydroxyanthracene derivatives: A focus on aloin and aloe-emodin

Aloe dairy products have occupied a certain market share, and the interaction between the small bioactive molecules contained in aloe and milk proteins during product processing profoundly affects the performance of dairy products. In this study, two typical and potentially dangerous bioactive small molecules of aloe, aloin (AA) and aloe-emodin (AE), were selected to investigate their interaction mechanism with β-lactoglobulin (β-La). Computer simulations showed that AA/AE had the potential to form complexes with β-La, and the β-La-AA system exhibited a stronger binding affinity than the β-La-AE system. Fluorescence analysis showed that the binding affinity values of AA to β-La at 298 K were deduced to be (4.184 ± 1.06) × 104 M−1, meaning medium-strength interactions, comparatively, AE to β-La was weaker, were deduced to be (3.15 ± 1.25) × 103 M−1. In addition, the thermodynamic analysis found that ΔH0 and ΔS0 were positive in both the β-La-AA system and the β-La-AE system, which implies that the main driving force for the combination of AA/AE and β-La to form the ground state complex is the hydrophobic force. The conformation changes in β-La brought about by binding to AA/AE may alter the properties and functions of the protein, such as surface hydrophobicity and oxidation resistance. Analysis shows that β-La is potentially present in whey as an AA/AE carrier during the production of aloe milk.

A Brief Review of Hemp Fiber Length Measurement Techniques

Accurate fiber length measurement is essential for the processing and quality management of textile products. This article reviews the current methods used to measure fiber length, including manual, photoelectric, capacitive, and optical techniques. Existing sample preparation processes for natural fiber characterization have been primarily developed for cotton and wool fibers. However, hemp fibers present unique challenges due to their greater length variability, high strength, and low elongation, making some traditional sample preparation methods less effective. Image processing offers a promising approach for scalable and precise measurement of hemp fiber length. Nevertheless, current image processing techniques are limited by the inability to effectively handle overlapping fibers, which increases both the time and cost of testing. Continued research into developing more advanced segmentation algorithms could lead to more widely adopted commercial methods for fiber measurement.

Optimization of carbon emission in an integrated machine-piece scheduling and vehicle routing problem and its solution using MOPSO and NSGAII metaheuristic algorithms

The growth of the global economy is accompanied by significant energy consumption, and greenhouse gas emissions create various problems such as global warming and environmental degradation. To protect the environment, governments are seeking to reduce carbon emissions. Production systems that operate solely based on economic factors in the workshop only consider problems such as production speed, cost, and processing time. Two aspects can be effective in saving energy and reducing emissions at the production planning level: using routing to find the shortest path for collecting workpieces to the workshop, and turning off machines with long idle times and restarting them at the appropriate time. If the workshop production problem is combined with vehicle routing, a new problem arises. According to the research conducted so far, an integrated mathematical model for production routing has not been designed in a situation where the routing is before the production workshop. In this research, this bi-objective model is introduced, and it is solved using the augmented epsilon-constraint (AEC) method. The proposed mixed-integer linear programming model of this research includes three dimensions: environmental, social (customer satisfaction), and economic simultaneously. Given the high complexity of the mathematical model, MATLAB software and MOPSO and NSGA-II algorithms were used to solve it at higher dimensions. Seven evaluation criteria were used to compare the two proposed algorithms, and the results show that the MOPSO algorithm performs better. The findings suggest that minimizing pollution may involve sacrificing on-time delivery to customers. Consequently, decision-makers must carefully weigh the trade-off between reducing environmental impact and maintaining satisfactory delivery performance, ultimately deciding on an acceptable pollution level.

Separation and Purification of CHO Secretome and Extracellular Vesicles for Proteome Analysis.

For decades, host cell proteins (HCPs) have been investigated as putative contaminants in downstream processing of biopharmaceutical products of Chinese hamster ovary (CHO) cells. However, little is still known about the composition of the entire protein and vesicle environment in CHO cultivations. Ever evolving mass spectrometry techniques allow more and more insights into cell-cell communication processes and the composition of extracellular matrix, proteases, and further actively segregated compounds such as extracellular vesicles (EVs). EVs themselves are a heterologous group consisting of exosomes, ectosomes, and apoptotic vesicles. To specifically analyze these subsets of the secretome and determine beneficial and detrimental factors for a production process, targeted separation and purification techniques are necessary.In this chapter, we present our optimized workflows for a clear differentiation between directly secreted proteins and the vesicular protein content of different fractions (especially exosomal small EVs) from CHO cell supernatant for proteomic analysis by NanoLC ESI-MS.

Towards the fair regulation of all coca leaf derivatives in Colombia

Purpose The purpose of this study is to envision the possible path to regulation of the coca leaf and its derivatives. There are a range of possible coca derivatives that could be considered for the broader market and which could be conceived of as risk and harm reduction interventions, as well as have other nutritional and industrial uses. Design/methodology/approach The methodology consists of a historical analysis of the advances in alternative uses of the coca leaf within a commercial market in Colombia as a means of providing greater economic capacity to communities that cultivate the plant, while exploring the nutritional and industrial benefits of the plant. Findings Low-risk products, such as coca leaf and coca tea, could be regulated under the same criteria as coffee or other caffeinated beverages. With a more diverse range of products on the market, consumers can make more informed decisions about their consumption, particularly regarding the associated risks and the effects they desire. Practical implications The legal regulation of coca leaf products implies the creation of a regulatory government agency specialized in the subject, as well as monitor and evaluate the cultivation and processing of products. The production of the coca leaf would still be in the hands of the cultivating communities but would fall under the control and monitoring of the government. Social implications The legal regulation of the coca leaf could have strong impacts on cultivating communities to guarantee their human rights and provide greater protection. Various industries have expressed an interest in using coca leaf derivatives and could represent economic opportunities for communities that cultivate. Originality/value Minimal work has been done on the regulation of coca leaf although there are some international examples that could be relevant in Bolivia and Perú. There is a need to continue exploring the multiple uses of the leaf to reach greater international consensus on its rescheduling.

Assessment of Whole Grain Ancient Wheat Sourdough in Lyophilised and Native Forms for Cookie Formulation

This study explored the potential of two forms of sourdough—native and lyophilised—obtained through the spontaneous fermentation of whole grain flours from ancient wheat varieties, for cookie production. The research involved evaluated the dough’s rheological properties through creep and recovery measurements and Mixolab analysis, assessing proximate composition, physical attributes, texture, colour, and sensory characteristics using the Rate-all-that-apply (RATA) method. The rheological analysis revealed that native sourdough significantly impacted dough behaviour, making it more challenging to process. Although differences were observed in the proximate composition, colour, and texture, these factors did not influence the samples as much as the rheological parameters. Sensory evaluation identified Khorasan lyophilised sourdough, along with its control sample, as the most promising, while modern wheat, spelt, and emmer exhibited potentially undesirable attributes. Based on these findings, it was concluded that lyophilised Khorasan sourdough was very favourable for cookie production and should be considered for further in-depth research and development. This suggests that the lyophilised forms of ancient wheats could offer valuable alternatives for cookie formulation, with implications for both the processing and sensory attributes of the final product.

Analysis of Entropy Optimization in MHD Flow of Non-Newtonian Nanofluids with Chemical Reaction and Thermal Energies

Investigation of nanofluid flows under various conditions is becoming fascinating research due to its numerous applications in many science and engineering fields such as solar energy, geothermal energy, water purification, glass blowing, enhanced oil recovery, petroleum production and food processing. For the present requirements in thermal energy applications, this mathematical model is considered to explore the diffusion and heat source effects on the flow of conductive Casson and Maxwell nanofluids in a porous medium on an elongating sheet with a chemical reaction. Further, the effects of viscous dissipation and thermal radiation are also examined. Moreover, the entropy generation is analyzed since this approach is employed in solar energy exchangers. The governing equations and the corresponding boundary conditions are constructed. This system of partial differential equations (PDEs) is changed into a system of nonlinear ordinary differential equations (ODEs) with the help of a suitable transformation and then solved numerically by the bvp5c MATLAB package. The influences of the physical parameters on the flow phenomena are discussed and presented through figures and tables. This analysis explains that the Casson fluid flow has a higher velocity field than the Maxwell fluid flow. The Nusselt number becomes higher as the Dufour numbers increase. It has also been noticed that increasing the Brinkmann number improves the entropy and, an increase in radiation enriches the temperature profile. The concentration of the fluid is decreased for the increasing values of the higher-order chemical reaction parameter. Furthermore, comparisons of the current results were conducted for limiting examples of the problem and found to be in good agreement with existing results in the literature.

Water hyacinth biorefinery: Improved biofuel production using Trichoderma atroviride pretreatment

AbstractThe pyrolysis of water hyacinth is gaining attention and acceptance as a resource recovery technique due to its availability and economic viability. However, the presence of lignin, one of the three major biomass fractions, presents significant challenges for profitable water hyacinth processing for biofuel production. Fungal pretreatment of water hyacinth for lignin breakdown has been explored but the application of Trichoderma atroviride as a pretreatment for pyrolysis is relatively novel. The efficacy of T. atroviride pretreatment in improving water hyacinth's pyrolytic products using a fixed‐bed reactor was therefore investigated in this study. The optimization process was studied using a central composite design in response surface methodology with Design Expert 13. Delignification of the biomass was established because the elemental analysis showed a 25.42% increase in cellulose content and a 23.40% and 3.37% decrease in lignin and hemicellulose content, respectively. The biomass pretreatment applied influenced the physical and chemical characteristics of the pyrolytic products. The highest pyrolysis oil yield increased by 25.81% at 575 °C and particle size 2290 μm, and the highest char yield decreased by 4.23% at 273 °C and particle size 1500 μm. This research is crucial for policy and research conversations as it offers a scientific basis for the application of T. atroviride pretreatment in biomass pyrolysis technology and emphasizes the optimal utilization of water hyacinths to obtain socio‐environmental benefits.

The signal peptide of BmNPV GP64 activates the ERAD pathway to regulate heterogeneous secretory protein expression

As a powerful eukaryotic expression vector, the baculovirus expression vector system (BEVS) is widely applied to the production of heterogeneous proteins for research and pharmaceutical purposes, while optimization of BEVS remains a work in progress for membrane or secreted protein expression. In this study, the impact of the signal peptide (SP) derived from Bombyx mori nucleopolyhedrovirus (BmNPV) GP64 protein on protein expression, secretion, and the endoplasmic reticulum-associated degradation (ERAD) pathway were investigated in BmN cells and BEVS. Transient expression studies in BmN cells revealed that SP alters the localization and expression levels of recombinant proteins, reducing intracellular accumulation while enhancing secretion efficiency. Quantitative analysis demonstrated that SP-mediated secretion was markedly higher compared to controls, albeit with lower total expression levels. Further exploration into SP-mediated ERAD pathway activation showed increased expression of BiP and other ERAD-associated genes (PDI, UFD1, S1P, and ASK1), correlating with higher SP-driven protein expression levels. RNA interference (RNAi) experiments elucidated that knockdown of ERAD-associated genes enhances both the secretion efficiency of SP-guided proteins and the infectivity of BmNPV. Particularly, interference with BiP demonstrated the most pronounced effect on protein secretion enhancement. Viral infection experiments further supported these findings, showing upregulated ERAD-associated genes during BmNPV infection, indicating their role in viral protein processing and infectivity. In conclusion, this study elucidates the complex interplay between SP-mediated protein secretion, ERAD pathway activation, and viral infectivity in BmNPV-infected cells. These insights suggest strategies for optimizing recombinant protein production and viral protein processing in baculovirus expression systems, with potential implications for biotechnological and biomedical applications. Further research could refine our understanding and manipulation of protein secretion pathways in insect cell-based expression systems.

These products include primary processed products such as minimally processed carrots, dried carrots, pickles, preserves, fruit purees, yoghurt, juice, and essential oils, as well as processed by‐products including functional phytochemical extractions such as carotenoids, polyphenols, dietary fibers, active peptides, and glycoproteins. This review also covers other by‐products, including feeds, fast food boxes, and bioethanol production. Furthermore, cutting‐edge technologies related to carrot processing are discussed. The ultimate goal of this review is to provide researchers and practitioners with an in‐depth understanding of the present status of carrot production.

Optimization Study on Hardness of Cold Rolled Strip Steel Based on a Data-Driven Approach

As a key index to measure product quality and processability, the hardness of cold-rolled strip steel has an important influence on the production efficiency of iron and steel enterprises. However, due to the coupling between the process parameters at each stage of the continuous annealing process, and the setting of traditional process parameters depending on the experience of the operator, the lack of scientific and systematic optimization methods, which easily leads to the problem of high hardness fluctuation and low resource utilization. In this study, the data-driven method is used to conduct a preliminary correlation analysis to further clarify the optimal combination of process parameters for achieving the target hardness. The Pearson correlation coefficient is used to determine that carbon content, quenching furnace temperature, and strip speed significantly affect strip hardness. To further clarify the optimal combination of process parameters to achieve the target hardness, a Genetic Algorithm (GA) was tried in this study. The results show that the optimized process parameter combination can effectively improve the stability and consistency of strip hardness, and provide a scientific basis for the process parameter setting in the cold rolled strip production process, which is helpful for enterprises to improve product quality, reduce cost, and enhance market competitiveness.

ABSTRACT This study aims to modify different types of steel slag by heating, characterise the material and test its ability for adsorption of phosphate and ammonia from aquatic products processing wastewater. The materials were characterised by SEM, EDS, BET and FT-IR analyses. The effects of the type of steel slag, calcination temperature in steel slag modification, pH, contact time, adsorbent mass and initial pollutant concentration were investigated using the one-factor-at-a-time approach. The results show that the adsorption kinetic of the samples followed the pseudo-second-order model, whereas their adsorption isotherm fitted well with the monomolecular adsorptive Langmuir with a maximum phosphate adsorption capacity of 45.045 mgPO43-/g. Optimisation using Response Surface Methodology was conducted with the independent factors (adsorbent doses, contact time and calcination temperature of steel slag) and response (removal efficiency of phosphate). The temperature and dosage of the material significantly affected phosphate removal efficiency and optimisation conditions were suggested. Validation of one optimum condition at the calcination temperature of 801°C, the adsorbent dosage of 11.9 g/L and the contact time of 72 min using real aquatic products processing wastewater resulted in the removal efficiencies of 86.93, 87.59, 7.76 and 7.58% for phosphate, total phosphorus, ammonia and total nitrogen, respectively.

Research Progress on the Mechanism of the Impact of Myofibrillar Protein Oxidation on the Flavor of Meat Products.

Myofibrillar proteins primarily consist of myosin, actin, myogenin, and actomyosin. These proteins form complex networks within muscle fibers and are crucial to the physical and chemical properties of meat. Additionally, myofibrillar proteins serve as significant substrates for the adsorption of volatile flavor compounds, including aldehydes, alcohols, ketones, and sulfur and nitrogen compounds, which contribute to the overall flavor profile of meat products. A series of chemical reactions occur during the processing, storage, and transportation of meat products. Oxidation is one of the most significant reactions. Oxidative modification can alter the physical and chemical properties of proteins, ultimately impacting the sensory quality of meat products, including flavor, taste, and color. In recent years, considerable attention has been focused on the effects of protein oxidation on meat quality and its regulation. This study investigates the impact of myofibrillar protein oxidation on the sensory attributes of meat products by analyzing the oxidation processes and the factors that initiate myofibrillar protein oxidation. Additionally, it explores the control of myofibrillar protein oxidation and its implications on the sensory properties of meat products, providing theoretical insights relevant to meat processing methods and quality control procedures.

Interrelation of protein metabolism and autonomic nervous system in laying hens

The study of factors influencing the processes of protein metabolism in the poultry body will help to better balance the diet, which will help to more effectively stimulate the growth of animal productivity. The aim of the work was to investigate the role of the autonomic nervous system in protein metabolism and to take into account the individual characteristics of the poultry organism, characterized by different tone of the autonomic nervous system. The formation of experimental groups of animals was carried out by electrocardiographic examination using the Baevsky method, on the basis of which three experimental groups of animals were formed: normotonics, vagotonics, and sympathotonics. The blood serum was studied using a LabLine-010 spectrophotometer (Austria) and test systems from Laboratory Granum LLC, Kharkiv. Kharkiv. According to the results of the biochemical study, it was found that the content of total protein, which was compared with the experimental group of normotonics (46.10±1.35 g/l) with a balanced sympathovagal balance, was 14.8 % lower than that of the experimental group of sympathotonics (54.10±2.60 g/l) (P<0.01) and 18.1 % lower than that of the experimental group of vagotonics (56.30±1.90 g/l) (P<0.01). The albumin content, which was compared with the experimental group of normotonics (4.56±0.55 g/l) with a balanced sympathovagal balance, was 40.55 % lower than that of the experimental group of sympathotonics (6.96±0.49 g/l) (P<0.001) and 1.5 times lower than that of the experimental group of vagotonics (7.67±0.38 g/l) (P<0.01). The creatinine content compared to the normotonic group (47.12±0.77) with a balanced sympathovagal balance was lower than that of the experimental group by 6.77 % compared to the experimental group of vagotonic poultry (7.67±0.38 g/l) (P<0.001). Taking into account the individual characteristics of the poultry organism and establishing the tone of the autonomic nervous system, it was determined that the autonomic nervous system has an effect on protein metabolism in poultry. The prospect of further research is to study the use of nanoaquahelate preparations to improve productivity and metabolic processes, taking into account the tone of the autonomic nervous system.
