Biofilms are microbial communities nested in self-secreted extracellular polymeric substances that can provide microorganisms with strong tolerance and a favorable living environment. Deepening the understanding and research on positive effects of microbial biofilms is consequently necessary, since most researches focuses on how to control biofilms formation to reduce food safety issues. This paper highlights beneficial roles of biofilms including the formation mechanism, influencing factors, health benefits, strategies to improve its film-forming efficiency, as well as applications especially in fields of food industry, agriculture and husbandry, and environmental management. Beneficial biofilms can be affected by multiple factors such as strain characteristics, media composition, signal molecules, and carrier materials. The biofilm barrier composed of beneficial bacteria provides a more favorable microecological environment, keeping bacteria survival longer, and its derived metabolites are better conducive to health. However, in the practical application of biofilms, there are still significant challenges, especially in terms of film-forming efficiency, stability, and safety assessment. Continuous research is needed to discover innovative methods of utilizing biofilms for sustainable food development in the future, in order to fully unleash its potential and promote its application in the food industry.

Consumer interest in a shift toward moderating animal products in their diets (flexitarian) is constantly increasing. One way to meet this consumer demand is through hybrid meat products, defined as those in which a portion of the meat is substituted by plant protein. This review article aims to analyze literature regarding the impact of replacing meat proteins with other alternative proteins on the functional and nutritional properties of hybrid products. Different food matrices created by hybrid products have impact on the digestive processes and outcomes in vitro and in vivo, and the bioavailability of protein, lipid, and mineral nutrients is modified, hence these aspects are reviewed. The functional properties of hybrid products change with regard to type of alternative protein source used. In hybrid products, deficiencies in amino acids in alternative proteins are balanced by amino acids from meat proteins, resulting in wholesome products. Additionally, animal protein degrades into peptides in the gut which bind non-animal iron and increase the availability of iron from the alternative protein material. This relationship may support the development of hybrid products offering products with increased iron bioavailability and a previously unseen beneficial nutritional composition. The effects of alternative protein addition in hybrid meat products on protein and mineral digestibility remains unclear. More research is required to clarify the interaction of the protein-food matrix as well as its effects on digestibility. Very little research has been conducted on the oxidative stability and microbiological safety of hybrid products.

Ultrasound is regarded as an effective and promising non-thermal technology, and it is increasingly investigated in recent years in the meat field in order to speed up the processing or improve the quality properties. This review comprehensively summarizes the contributions of ultrasonic application in seven aspects (curing, tenderization, emulsification, freezing, thawing, sterilization and flavor) in the processing of meat and/or its products, discussing the different types of application with some examples, and deeply explaining the involved mechanisms. Ultrasound-triggered cavitation effect is confirmed to be a pretty important reason for the promotion of processing efficiency and quality attributes of meat and/or its products. The present work will provide an in-depth systematic review on the knowledge of ultrasonic technology for a better understanding of the positive aspects of the application of such technology in the meat field.

Soybeans (Glycine max [L.] Merr.) are a globally significant crop, valued for their high protein content and nutritional versatility. However, they contain anti-nutritional factors (ANFs) that can interfere with nutrient absorption and pose health risks. This comprehensive review examines the presence and impact of key ANFs in soybeans, such as trypsin inhibitors, lectins, oxalates, phytates, tannins, and soybean polysaccharides, based on recent literature. The physiological roles, potential health hazards of the ANFs, and the detailed balance between their harmful and beneficial effects on human health, as well as the efficacy of deactivation or removal techniques in food processing, were discussed. The findings highlight the dual nature of ANFs in soybeans. Some ANFs have been found to offer health benefits include acting as antioxidants, potentially reducing the risk of cancer, and exhibiting anti-inflammatory effects. However, it is important to note that the same ANFs can also have negative impacts. For instance, trypsin inhibitors, lectins, and tannins may lead to gastrointestinal discomfort and contribute to mineral deficiencies when consumed in excess or without proper processing. This review will provide a clear understanding of the role of ANFs in soybean-based diets and to inform future research and food processing strategies.

Bread consumption dates back thousands of years, being one of the oldest and most widespread staple food worldwide. While bread is often associated with taste, pleasure, and tradition, its perception as a vehicle of nutrition and health remains complex. Today, there is no scientific consensus on whether bread consumption is beneficial or deleterious to human health. The objective of this review is therefore to present and discuss epidemiological and clinical evidence on the nutritional contribution of bread and its relationship with health. We also present different aspects of bread such as flour type and inclusions that may modulate this relationship. Studies included in this review investigate bread as part of a dietary pattern as well as the effect of bread alone on overweight, cardiometabolic health, and digestive health. Bread is an integral part of diets around the world, with a significant contribution to key nutrients. Although evidence on the impact of bread consumption on health is still lacking and depends on the overall diet, whole grain breads have shown consistent beneficial effects on human health. Substitution modeling studies and well-designed clinical trials are warranted to fill the research gaps and understand the role of bread consumption in health and disease.

In recent years, there has been a growing demand for alternative food processing technologies that can improve food safety while preserving the nutritional quality of food products. Traditional thermal processing methods can lead to nutrient loss and degradation, prompting the exploration of novel approaches. Cold plasma (CP) technology, an emerging non-thermal food processing technique, has gained significant attention for its potential in the food industry. We provide herein, an introduction to CP and an overview of the technology, highlighting its potential advantages in safety, efficiency, and environmental friendliness.

The prediction of food shelf life has become a vital tool for distributors and consumers, enabling them to determine storage and optimal edible time, thus avoiding unexpected food waste. Artificial neural network (ANN) have emerged as an effective, fast and accurate method for modeling, simulating and predicting shelf life in food. ANNs are capable of tackling nonlinear, complex and ill-defined problems between the variables without prior knowledge. ANN model exhibited excellent fit performance evidenced by low root mean squared error and high correlation coefficient. The low relative error between actual values and predicted values from the ANN model demonstrates its high accuracy. This paper describes the modeling of ANN in food quality prediction, encompassing commonly used ANN architectures, ANN simulation techniques, and criteria for evaluating ANN model performance. The review focuses on the application of ANN for modeling nonlinear food quality during storage, including dairy, meat, aquatic, fruits, and vegetables products. The future prospects of ANN development mainly focus on optimal models and learning algorithm selection, multiple model fusion, self-learning and self-correcting shelf-life prediction model development, and the potential utilization of deep learning techniques.

Microalgae contain a diverse range of high-value compounds that can be utilized directly or fractionated to obtain components with even greater value-added potential. With the use of microalgae for food and medical purposes, there is a growing interest in their digestive properties and impact on human gut health. The extraction, separation, and purification of these components are key processes in the industrial application of microalgae. Innovative technologies used to extract and purify microalgal high-added-value compounds are key for their efficient utilization and evaluation. This review's comprehensive literature review was performed to highlight the main high-added-value microalgal components. The technologies for obtaining bioactive compounds from microalgae are being developed rapidly, various innovative, efficient, green separation and purification technologies are emerging, thus helping in the scaling-up and subsequent commercialization of microalgae products. Finally, the digestive behavior of microalgae nutrients and their health effects on the human gut microbiota were discussed. Microalgal nutrients exhibit favorable digestive properties and certain components have been shown to benefit gut microbes. The reality that must be faced is that multiple processes are still required for microalgae raw materials to final usable products, involving energy, time consumption and loss of ingredients, which still face challenges.

Functional foods and their by-products contain a wide range of bioactive components with an array of health benefits and were proposed to improve public health, well-being, and others. To achieve a circular economy, the processing and extraction of flavonoids, phenolic compounds, and others from functional food and agri-food wastes will require the use of environmentally friendly, sustainable, and a low-cost solution. Extraction methods that can eliminate the use of organic solvents, suitable for use in the laboratory and production of extracts will be covered. This will include subcritical water extraction (SBE), pressurized hot water extraction (PHWE), supercritical fluid extraction (SFE), and others. Based on the selected analytical methods, the determination of the marker or bioactive compounds and chemical fingerprints will provide the control measures to identify the batch-to-batch variation of the composition of the functional food products obtained. The combination of chemical standardization with antioxidant assay, such as DPPH and ABTS⁺ will provide further information on the quality of the extracts. Lastly, to ascertain the biological and physiological relevance of the antioxidant properties of the target sample, treatment of the antioxidant compounds or extracts was carried out using cellular models, and validated using other experimental endpoints, such as metabolomics.

The extensive utilization of pesticides in agriculture has resulted in the presence of pesticide residues in food and feed, which poses a significant threat to human health. Various physical and chemical methods have been proposed to remove pesticides, but most of these methods are either costly or susceptible to secondary contamination. Consequently, the utilization of microorganisms, such as probiotics, for eliminating pesticides, has emerged as a promising alternative. Probiotics, including lactic acid bacteria, yeasts, and fungi, have demonstrated remarkable efficiency and convenience in eliminating pesticide residues from food or feed. To promote the application of probiotic decontamination, this review examines the current research status on the utilization of probiotics for pesticide reduction. The mechanisms involved in microbial decontamination are discussed, along with the toxicity and potential health risks of degradation products. Furthermore, the review explores strategies to enhance probiotic detoxification and outlines prospects for future development.
