Pasta as a Source of Minerals in the Diets of Poles; Effect of Culinary Processing of Pasta on the Content of Minerals

Wild Garlic (Allium ursinum) Preparations in the Design of Novel Functional Pasta

This study investigated the design of novel pasta enriched with different forms of wild garlic (WG): a powder, an extract and an encapsulated extract applied at three enrichment levels (low/middle/high). The effect of cooking on changes in the content of bioactive compounds, antioxidative activity, cooking behaviour, texture, colour and sensory properties of the cooked pasta was evaluated. WG preparations significantly increased the antioxidant potential (by 185-600%) as well as the content of phenolics (by 26-146%), flavonoids (by 40-360%) and potassium (up to three-fold) in the cooked pasta, depending on WG type and enrichment level. Flavonoids were dominantly present in the free form. Cooking resulted in a significant loss of flavonoids (39-75%) whereas phenolics were liberated from the matrix. The highest increase in total phenolics and antioxidant activity was exerted by the WG powder and extract. Pasta hardness and adhesiveness were increased, but encapsulated WG deteriorated cooking behaviour. The best-scored enriched pasta regarding sensory quality and texture was that enriched with WG powder at the low/moderate level.

Initiatives to Reduce the Content of Sodium in Food Products and Meals and Improve the Population's Health

Table salt is the main source of sodium (Na) in the human diet. Excessive supply of Na in a diet is strongly linked to many non-communicable human diseases, such as hypertension, obesity and stomach cancer. The World Health Organization recommends that daily intake of salt in adult diets should be kept below 5 g/person/day, which corresponds to 2 g Na/person/day. However, on average, adults consume about 9-10 g/person/day, and children and young people about 7-8 g/person/day. Initiatives to reduce salt intake include modifications of food composition in collaboration with the food industry, education of consumers, salt marking on foodstuff labels and taxation of salt. A need also exists to educate society so that they choose low-sodium products. In view of the food technology and amount of salt intake, the most important and the easiest change to make is to reduce the content of salt in baked goods. This paper analyses the results of surveys regarding strategies to reduce salt content in food products and considers multifaceted initiatives to reduce salt intake as a possible efficient method of improving the population's health status.

CNN-LSTM Neural Network for Identification of Pre-Cooked Pasta Products in Different Physical States Using Infrared Spectroscopy

Infrared (IR) spectroscopy is nondestructive, fast, and straightforward. Recently, a growing number of pasta companies have been using IR spectroscopy combined with chemometrics to quickly determine sample parameters. However, fewer models have used deep learning models to classify cooked wheat food products and even fewer have used deep learning models to classify Italian pasta. To solve these problems, an improved CNN-LSTM neural network is proposed to identify pasta in different physical states (frozen vs. thawed) using IR spectroscopy. A one-dimensional convolutional neural network (1D-CNN) and long short-term memory (LSTM) were constructed to extract the local abstraction and sequence position information from the spectra, respectively. The results showed that the accuracy of the CNN-LSTM model reached 100% after using principal component analysis (PCA) on the Italian pasta spectral data in the thawed state and 99.44% after using PCA on the Italian pasta spectral data in the frozen form, verifying that the method has high analytical accuracy and generalization. Therefore, the CNN-LSTM neural network combined with IR spectroscopy helps to identify different pasta products.

Use of Microalgae Biomass for Fortification of Food Products from Grain

This article describes the use of Chlorella sorokiniana biomass additives in pasta recipes to enrich the product with biologically active phytonutrients, as well as to achieve the desired color range without the use of synthetic dyes. Samples of dry biomass were obtained by the cultivation of microalgae C. sorokiniana (strain), its quality indicators and nutritional value were determined for use as a food additive. A method of using dry biomass of microalgae C. sorokiniana as a phytoadditive to replace 5% of flour mixture for effective enrichment of pasta with biologically active phytonutrients was proposed. The choice of the optimal amount of addition of microalgae biomass was proved since it turned out that the replacement of flour should be no more than 5% due to the distinct fish flavor of the final product. The present study was conducted to evaluate the effect of adding dry biomass of Chlorella microalgae on total protein, lipid, chlorophyll, and carotenoid content. Substitution of 5% of pasta flour led to an increase in the content of proteins and lipids to 15.7 ± 0.50% and 4.1 ± 0.06%, respectively. Meanwhile, the addition of microalgae Chlorella to pasta has helped to increase the content of polyunsaturated fatty acids, chlorophyll, and carotenoids which are necessary for the prevention of foodborne diseases. The aim of this study is to develop pasta recipe with additives of microalgae biomass C. sorokiniana and study their quality indicators.
