Special Issue Information

Dear Colleagues,

The focus of this Special Issue is technological innovation in food analysis and processing, with particular emphasis on effectiveness and sustainability in terms of usable resources, time, energy and cost savings.

Anthropogenic pressure on the earth’s finite resources has generated serious concerns about the resilience of the contemporary food chains. By gathering your input, we aim to provide cost-effective and reliable solutions to scholars, researchers and stakeholders in the field of sustainable food production, and to promote the adoption of alternative approaches and/or ingredients in the current food-manufacturing system.

Original research articles and reviews are welcome.

Research areas may include (but are not limited to) the following topics:

  • tech and biotech approaches to improving overall food quality;
  • technologies for reducing or recovering water, food waste and energy in factories;
  • exploitation of novel technologies for quality assessment or traceability of food;
  • energetic characterization of food processes through modelling and in situ trials;
  • alternative protein sources and production methods both for animal feed and food production;
  • alternative packaging solutions and methods for extending shelf life;
  • characterization and testing (using conventional or mild technologies, etc.) of alternative and local ingredients for healthier and more sustainable food production;
  • food distribution and logistics; policies and laws regarding sustainable food processing.

Papers including the study and application of advanced ICT (nanosensors, IoT, blockchain) to the food industry are especially welcome.

We look forward to receiving your contributions.

The decrease in bread consumption in the daily diet observed in recent years results from the growing awareness of consumers and the desire to promote a healthy lifestyle. The valorization of sugar by-products allows for the design of new food products intended for health-conscious consumers. The aim of this study was to assess the possibility of using sugar beet pulp (SBP), without and with molasses, in bakery recipes as part of a strategy promoting increased consumption of foods rich in bioactive compounds. The basic composition of SBP was examined, and wheat flour mixtures with their addition at 0, 1, 5, and 10% were prepared. The rheological properties of the dough with flour blend samples were determined using Mixolab®. The technological quality of the bread, its nutritional value, and its antioxidant potential were assessed. The research results indicate that fortifying bread up to 5% SBP allows for obtaining products of acceptable sensory and technological quality. The bread with 5% molasses SBP (mSBP) compared to the sample with SBP without molasses (umSBP) was characterized by greater bread volume and crumb moisture, a darker color of the crumb, a more appropriate color of the crust (golden-brown), more favorable, thin-walled pores, and a fluffier crumb. Moreover, the samples enriched with mSBP contained more total polyphenols (by approx. 40%) and showed higher antioxidant activity (by approx. 50%) than the bread with umSBP. Additionally, for bread samples with 5% or more SBP added, a nutritional claim could be made that they are a “source of fiber” (i.e., at least 3 g per 100 g of product). Full article

The aim of this study was to evaluate the content of selected minerals and total phenolic and flavonoid content of wheat bread and bread enriched with varying amounts of carrot powder (CP) and pumpkin powder (PP). In addition, the coverage of daily requirements of selected minerals was evaluated after the consumption of 100 g of each type of bread. The research included seven types of bread: wheat bread (WB) and bread enriched with 10%, 20%, and 30% CP and PP. The vegetable powders were obtained by freeze-drying. The concentrations of minerals—sodium (Na), potassium (K), calcium (Ca), magnesium (Mg), iron (Fe), zinc (Zn), copper (Cu), and manganese (Mn)—were determined by atomic absorption spectroscopy (AAS) method. Coverage of daily requirements after consumption of a serving of bread was determined based on Recommended Daily Allowance (RDA) and Adequate Intake (AI) ratios for minerals, according to the nutritional standards for the Polish population. The addition of 10% PP led to a greater increase in Na, K, Mg, and Cu in the bread compared to CP, while for Ca, Fe, Zn, and Mn a greater increase was observed with the addition of 10% CP than PP. Among macronutrients, the greatest changes in content were recorded for Ca—the addition of 10 and 20% CP and PP resulted in increases of 66, 113, 51 and 59%. Among micronutrients, the addition of CP and PP to wheat bread caused the largest changes in Cu (46–150% increase) and Mn (25–99% increase) content. Additionally, there was a tenfold increase in total phenolic content (TPC) when 30% CP was added to the bread. Consuming 100 g of bread with CP and PP provided the greatest coverage of K (41–60%), Cu (8–17.5%), and Mn (6–17%). These findings suggest that fortification of bread with vegetable powders has the potential to be a useful method of enriching the mineral composition and increasing the proportion of selected minerals in the human diet.

Three different sweet red wines were produced using Tempranillo grapes with three different sugar concentrations: 25, 50 and 75 g/L, using sulfur dioxide and low temperature to stop the alcoholic fermentation. They were compared to the wine produced without stopping the alcoholic fermentation. Cold pre-fermentation macerations and ultrasound during the post-fermentation stage were applied to try to improve the organoleptic properties specifically for sweet wines. The treatment with ultrasound after stopping the fermentation enhanced the extraction of anthocyanins compared to the wines produced without ultrasound, increasing the red color of the final wines, resulting in increments in the range of 16–30%. In any case, significant differences were found between the regular dry red wine and the sweet wines in terms of polyphenolic content, anthocyanin, tannin concentration and absorbance at 520 nm, with lower contents for the sweet wines. The wines were evaluated by different tasting panels showing different results depending on the tasting panel composition. First, an inverse relationship was observed between the sweetness of the wines and their acidity, bitterness, and astringency descriptors. Additionally, wines with higher sugar levels were described as having the most fruity aromas. Finally, no differences in vegetal aromas were found in the different wines. Full article

Nowadays, food waste is seen as a complex problem with effects on the social, economic, and environmental domains. Even though this view is widely held, it is frequently believed that individual acts have little to no impact on the issue. But just like with recycling, there may be a significant impact if people start adopting more sustainable eating habits. We suggest using a cutting-edge convolutional neural network (CNN) model to identify food in light of these factors. To improve performance, this model makes use of several strategies, such as fine-tuning and transfer learning. Additionally, we suggest using the Selenium library to create a dataset by employing the web scraping technique. This strategy solves the problem that many open-source datasets have with the overrepresentation of foods from the Asian continent by enabling the addition of foods to the dataset in a customized way. First, using the PRISMA methodology, a thorough examination of recent research in this field will be carried out. We will talk about the shortcomings of the most widely used dataset (Food-101), which prevent the ResNet-50 model from performing well. Using this information, a smartphone app that can identify food and suggest recipes based on the ingredients it finds could be developed. This would prevent food waste that results from the lack of imagination and patience of most people. The food recognition model used was the ResNet-50 convolutional neural network, which achieved 90% accuracy for the validation set and roughly 97% accuracy in training. Full article

The marketing value of table grapes is contingent upon several quality requirements, mostly related to microbial decay, sugar/acidity ratio, and colour. This research explores the impact of combining organic-cultured compatible techniques to delay disorders along with organic grape distribution in post-harvest. Aurebasidum pullulans in-field application on grape bunches at three growing stages as a biocontrol agent against grey mould growth coupled with massive modified atmosphere packaging (MMAP; 20% CO2, 10% O2) equipped with a breathable valve was tested. The in-field treatment had a significant impact on the colour and sugar content of the grapes at harvest and the mould count evolution during storage, whilst the trend of the other parameters was mainly affected by the interaction of the variables tested. The untreated batch experienced the worst behaviour and the packaging was paramount in preserving the moisture content and appearance of the bunches. The findings of this study may contribute to developing novel practices for setting a smart distribution of organic table grapes and reducing food waste. Full article

The aim of the study was to evaluate the effect of heat- (95 °C) and/or salt (0.1 M NaCl) treatment on the physical stability and rheological properties of oil-in-water emulsions stabilized with chickpea protein concentrates (CPCs) for various purposes. Thus, the particle size distribution (PSD), shear behavior, and long-term Turbiscan stability of the prepared emulsions were examined. The oscillatory (dynamic) measurements were also performed to obtain information on the viscoelasticity of tested fluids during thermal treatment. The obtained results indicated that the emulsion stabilized with gelling CPC (eCg) was Newtonian fluid with a homogeneous structure, but susceptible to creaming. Heat-treated eCg exhibited a sol–gel transition at 86 °C and formed fine-stranded aggregates without affecting stability. In turn, heat-induced gelation of eCg in the presence of 0.1 M NaCl resulted in the formation of an aggregated, spatial gel network, stabilization of the system, and a significant change in both shear rheological properties and PSD. Contrariwise, emulsions stabilized with standard CPC (eCs) were unstable heterogeneous systems containing both fine particles < 1 μm and coarse particles of about 100 μm, exhibiting shear-thinning and yield stress. The heat-induced viscoelasticity of eCs was reversible, while heat- and salt-treated emulsions did not form a gel. Full article

The objective of this study is an investigation of the influence of six different plastic packages (polyethylene terephthalate, high-density polyethylene, biodegradable high-density polyethylene, low-density polyethylene, polypropylene and polyamide polyethylene) on the migration of phthalate residues in smoked carp, trout and salmon stored at −18 °C for three and six months. Six phthalate residues concentrations were determined using the gas chromatography-mass spectrometry method. Diisobutyl phthalate (DIBP) and dibutyl phthalate (DBP) migrated the most into salmon meat from PAPE packaging after six months of storage, reaching 73.77 μg/kg and 78.45 μg/kg, respectively. The highest concentrations of bis(2-ethylhexyl) phthalate (DEHP) after six months of storage were present in salmon meat packed in polyamide polyethylene (253.56 μg/kg) and the lowest in carp meat packages in polypropylene (157.72 μg/kg). Phthalate residues in all the samples showed higher levels after three and six months of storage compared to the control sample. Among the investigated phthalates, polypropylene was the material with the lowest migration into fish meat. A further amount of DEHP migration in the fish was detected with a higher fat content. We acknowledge that levels of phthalates should be monitored, and research in this field should be continued, especially since there are no legal restrictions regarding the maximum level of phthalates in food.

Contamination of the inner surface of milk hoses of milking systems with milk residues, water residues and pathogenic microflora has a negative impact on milk quality and can affect the accuracy of light-scattering sensors measuring milk quality parameters. A three-stage study of the influence of milking system operating conditions on the accuracy of a light-scattering sensor is presented. The growth of pathogenic microflora on the inner surface of milk hoses was studied, the flow of milk and milk hoses rinsing was simulated and the accuracy of the light-scattering sensor was tested under conditions of low-quality rinsing of the milking system. A significant difference in the total microbial count was detected between the milk residues of healthy animals and the milk residues of animals with subclinical mastitis (1.2 × 104 CFU/mL and 9.2 × 104 CFU/mL). The presence of Staphylococcus (aureus and epidermidis) was detected in quantities much lower than those that could interfere with the analysis of milk quality parameters. Simulation modeling allowed us to prove that even when rinsing with hot water (80 °C) without chemical solutions, pathogenic microflora in milk hoses of the milking system will be suppressed. Modeling of the milk flow in the measuring chamber of the device showed the stable replacement of milk in the measuring chamber and provided actual measurements of milk quality parameters. It has been determined that low-quality rinsing and water residues in milk hoses lead to a significant increase in measurement error up to 15–20% during the first 30–40 s after the milking system starts operating. The study results confirm that the light-scattering sensors are resistant to such factors of the milking system operation as contamination by pathogenic microflora (S. aureus and S. epidermidis) and low-quality rinsing of milk hoses.

Currently, food waste is a global concern, a problem that arises mainly at the consumption level and generates environmental, economic, and social impacts. One way to reduce the food waste problem is to use the food we already have at home. However, this causes another concern, which is what to cook with certain foods. Sometimes we do not know what recipes can be made. Knowing which ingredients can be mixed and how to mix them can be a difficult task for a beginner cook, so selecting the right ingredients for a recipe is essential. Therefore, it is proposed to develop a recipe recommendation system through image recognition of food ingredients. Presently, the system is a web application that recognizes an image given by the user and recommends recipes containing the recognized ingredient. For this, a convolutional neural network model, the ResNet-50, was built to perform image recognition and trained with a dataset that contains about 36 classes of vegetables and fruits. Through this training, the model reached 96% accuracy in classifying the dataset images. The recommendation system uses the label of the recognized ingredient to obtain the recipes, which are searched through the Edamam API. Full article

This study demonstrates the effects of the freezing and frozen storage of anchovies prior to brining and dry-salting on quality changes and food safety during refrigerated storage (4 ± 1 °C). Fresh anchovies were divided into two groups, one of which was used as a control representing fresh raw material; the other was the experimental group and consisted of frozen and thawed anchovies stored at −18 °C for a year. Five different salt concentrations were used for brining (10, 15, 20, 25 and 30%) in addition to the dry-salting method. Microbiological, chemical, physical and sensory analyses were carried out during storage. Salt concentration and salting method had significant effects on the shelf-life of salted anchovy products, with the highest shelf-life corresponding to dry-salted anchovies (p < 0.05). The effect of using frozen and thawed raw materials for salting on the shelf-life depended on the processing method since the experimental dry-salted group had a shelf-life one month longer than that of the control group, while the opposite situation occurred for the brined samples, with one exception. Strong correlations were usually found between sensory values and chemical quality parameters (R2: 0.83–0.99 for the control group and 0.63–0.99 for the experimental group). The results demonstrated that the experimental group, with some exceptions, had better values for most quality and food safety parameters in comparison to the control group, indicating the advantage of using frozen and thawed raw materials before salting to prevent spoilage and enhance food safety. Considering that the experimental group was produced from one-year-stored raw material compared to the control group, the advantage of the freezing and frozen storage of anchovies can be accepted as much higher versus when freezing is not implemented. The positive effect is due to the fact that frozen anchovies absorb salt faster after thawing, especially in groups with high salt concentrations. Therefore, it can be concluded that frozen salted anchovies can be utilized for longer as they have a longer shelf-life, particularly when using either the 30% brining or dry-salting method.

The latest standard method for pesticides in food and feed (EN 15662:2018) is now generally used in control laboratories. However, routine analyses of the combination of hundreds of compounds and food matrices highlighted that false positive identification of pesticides in particular food matrices does occur. The aim of the study was to show relevant precedents when thorough investigation was necessary to make a decision on possibly compliant/non-compliant samples. Examples include the pesticide/commodity combination of atrazine-desethyl in date seed coffee, mepanipyrim in parsley root, myclobutanil in white peppercorn, primisulfuron-methyl in herb extract, propham in elderberry, quinoclamine in fennel and tebufenpyrad in dried ginger. These examples, which were presented for the first time, indicated that the identification criteria for some pesticides in certain food matrices, according to the SANTE/11312/2021 guideline, might fail: the general criteria as stable retention time and ion ratio could lead to an incorrect qualification of pesticides. Standard addition was useful not only in compensating for the background during mass spectrometric detection under the confirmatory analysis, but also in the identification process when negligible retention time difference was observed between the analytes and the interfering matrix compounds.

A product is characterized by low environmental impact if, during the whole process (from extraction of raw materials from solid natural matter to disposal), its negative contribution to environment modification is significantly reduced or eliminated. According to circular economy, it is important to take into consideration other aspects, such as the possibility to improve the efficiency of extraction process by modifying the principle on which it is based and allowing the recovery of not completely exhausted waste, obtaining other active ingredients, and favoring the recycling of normally eliminated materials. The purpose of this work was to propose more efficient and greener alternatives to conventional solid–liquid extraction processes. Major features are the rapidity of the process, extraction at room temperature and high yields. Rapid Solid–Liquid Dynamic Extraction (RSLDE) represents an innovative solid–liquid extraction technology that allows the solid matrices containing extractable substances in an organic or inorganic solvent and their mixtures to be exhausted in shorter time than current techniques. The principle at the basis of this novel process consists of the generation of a negative pressure gradient between the inside and the outside of the solid matrix, which induces the extraction of compounds not chemically linked to the solid matter, being insoluble in the extractant liquid. Therefore, this work focuses on how RSLDE can potentially bring several improvements in the field of solid–liquid extraction, especially for industrial applications. Full article
