UHPLC-Triple-TOF-MS Characterization, Antioxidant, Antimicrobial and Antiproliferative Activity of Raspberry ( L.) Seed Extracts.

The primary aim of this experiment was to investigate the bioactivity potential and polyphenolic profile of defatted raspberry seeds (DRS) extracts from three varieties (Willamette, Meeker, and Polka) using the in vitro tests HPLC-DAD and UHPLC-Triple-TOF-MS. Extracts were obtained using ultrasound-assisted extraction (UAE) or hydrolysis. The antioxidant activity of the extracts was tested using 1,1-diphenyl-2-picrylhydrazyl (DPPH), 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic) cation (ABTS), and ferric reducing antioxidant power (FRAP) assays.

This study aimed to investigate the impact of chicory root addition (20-40%) and extrusion conditions (moisture content from 16.3 to 22.5%, and screw speed from 500 to 900 rpm) on bioactive compounds content (inulin, sesquiterpene lactones, and polyphenols) of gluten-free rice snacks.

Development of a Novel Rice-Based Snack Enriched with Chicory Root: Physicochemical and Sensory Properties.

A novel rice-based snack enriched with chicory root flour (CRF) was developed by twin-screw extrusion. Chicory ( L.) is one of the promising medicinal plants for the development of innovative food and may be considered a functional food ingredient.

Addition of Combinedly Dehydrated Peach to the Cookies-Technological Quality Testing and Optimization.

Peach dehydrated by a combined method of osmodehydration and lyophilization is characterized by upgraded dehydration effectiveness and enhanced chemical and mineral matter content, and as such, is an interesting material to be applied to the cookies' formulation. Incorporation of this material requires testing and optimization of the addition level from the aspect of overall technological quality in order to obtain a new cookie product. Obtained cookie samples with different levels of dehydrated peach addition were subjected to the nutritive and technology quality parameters testing.

Identification of biomarkers in hydrosoluble extracts from spelt and wheat cultivated in different production systems.

Background: In the present paper, a method for differentiation between common and spelt wheat grown in different farming systems (biodynamic, ecological, integrated, conventional), based on biomarkers identified from aqueous flour extracts (nitrogen and 14 soluble carbohydrates) was employed.

Results: The identification and determination of soluble carbohydrate content were carried out using gas chromatography-mass spectrometry, with the UV spectrum generated by mass spectrometry for comparison with the WILEY database. Soluble carbohydrates were determined in the peak area between 21.

Chicory (Cichorium intybus L.) as a food ingredient - Nutritional composition, bioactivity, safety, and health claims: A review.

Chicory (Cichorium intybus L.) is a perennial herb from the Cichorium genus, Asteraceae family, and is worldwide cultivated. So far, chicory has been used mainly in animal feed, but also in several cases in the food industry: as salad, for teas and tea blends, for coffee supplementation, and as a source for the inulin production.

The effect of storage temperature and water activity on aflatoxin B accumulation in hull-less and hulled spelt grains.

Background: In concomitance with shifts in climate conditions in recent years, an increasingly frequent emergence of Aspergillus flavus and aflatoxins in cereals has been observed. In this study the effects of temperature (15, 23, 30 and 37 °C) and water activity (a ) (0.85, 0.

Serum Concentration of Hepcidin as an Indicator of Iron Reserves in Children.

Background: Anemia represents a significant cause of maternal and perinatal mortality, as well as child mortality. The aim of the research was to determine the serum concentration of hepcidin in children aged 6 months to 2 years and adolescents aged 11 to 19 years which suffer from iron deficiency anemia and compare it with the serum concentration of hepcidin in the control groups, as well as to determine its connection with the parameters of the iron metabolism.

Methods: The research included 173 examinees, 89 of them suffered from iron deficiency anemia and 84 did not suffer from iron deficiency anemia (the latter represented the control group).

A New Concept to Secure Food Safety Standards against Fusarium Species and Aspergillus Flavus and Their Toxins in Maize.

Commercial maize hybrids are exposed to different degrees of ear infection by toxigenic fungal species and toxin contamination. Their resistance to different fungi and toxin relationships are largely unknown. Without this knowledge, screening and breeding are not possible for these pathogens.

Betaine in Cereal Grains and Grain-Based Products.

Betaine is a non-essential nutrient which performs several important physiological functions in organisms. Abundant data exist to suggest that betaine has a potential for prevention of chronic diseases and that its dietary intake may contribute to overall health enhancement. Several studies have pointed out that the betaine status of the general population is inadequate and have suggested nutritional strategies to improve dietary intake of betaine.

Breadmaking performance and textural changes during storage of composite breads made from spelt wheat and different forms of amaranth grain.

The objectives of the present study were to assess the baking properties of composite spelt wheat-amaranth blends and to study the staling of composite breads during a six-day storage. Different forms of amaranth grains were added to spelt bread formulation: native amaranth flour and flour from popped amaranth, including their scalded and non-scalded variants. Native amaranth flour (both scalded and non-scalded) gave loaves with the highest volume and contributed to significantly softer crumb but not in comparison to the control bread.

Extraction methods of Amaranthus sp. grain oil isolation.

Background: Amaranthus sp. is a fast-growing crop with well-known beneficial nutritional values (rich in protein, fat, dietary fiber, ash, and minerals, especially calcium and sodium, and containing a higher amount of lysine than conventional cereals). Amaranthus sp.

Quality of gingernut type biscuits as affected by varying fat content and partial replacement of honey with molasses.

Gingernut type biscuits were prepared with varying fat content (10, 20, and 30 % w/w flour basis) and with sugar beet molasses replacing 0, 25, and 50 % w/w of the honey in the formulation. To evaluate the effects of these modifications, dough properties, and the physical, and sensory properties, and chemical composition of the biscuits were determined. Dough properties were significantly affected by the fat content; higher fat gave softer dough with reduced adhesiveness, cohesiveness and springiness.

Characterization of the liposoluble fraction of common wheat (Triticum aestivum) and spelt (T. aestivum ssp. spelta) flours using multivariate analysis.

Background: In the present paper, a special method for derivatization of liposoluble extract of common wheat and spelt flours was employed which enables simultaneous detection of fatty acid and non-saponifiable lipid fractions.

Results: Gas chromatographic-mass spectrometric analytical data for both fractions were separately analyzed by multivariate statistical techniques to model classes of different common wheat and spelt cultivars. Cluster analysis was used, and the results obtained revealed that better discrimination of samples was achieved by analyzing the peak area after 16 min retention time (non-saponifiable lipids), rather than commonly used peak area between 12 and 16 min (fatty acid fraction), due to more distinctive positions of points in factor space, even though the distances between points for fatty acid fraction (12-16 min) were greater.

Status quo and future research challenges on organic food quality determination with focus on laboratory methods.

Organic food quality determination needs multi-dimensional evaluation tools. The main focus is on the authentication as an analytical verification of the certification process. New fingerprinting approaches such as ultra-performance liquid chromatography-mass spectrometry, gas chromatography-mass spectrometry, direct analysis in real time-high-resolution mass spectrometry as well as crystallization with and without the presence of additives seem to be promising methods in terms of time of analysis and detecting organic system-related parameters.
