Research on the quality of sea buckthorn (Hippophae rhamnoides L.) berry processing products was done at Vytautas Magnus University Agriculture Academy in 2019. For the studies, the juice was squeezed from the defrosted sea buckthorn berries, and was stored in the refrigerator until separated into three fractions: solids, oil (oil No. 1) and juice. The berry cake remaining after squeezing the juice was dried and filled with unrefined sunflower oil. After 2 weeks, the oil (oil No. 2) was separated from the cake. The aim of the research was to determine the chemical composition and quality indices of sea buckthorn berry processing products. The content of soluble solids, titratable acidity, vitamin C and total carotenoid content were determined by standard methods in sea buckthorn juice, solids, berry press cake and in oil No. 1 and No. 2. The acid value, iodine value, peroxides value, induction period and colour of sea buckthorn berry oil No. 1 and No. 2 were determined. The research data were analysed by the factorial analysis of variance (ANOVA). Arithmetical means and standard deviation of the data were calculated. Statistical reliability was assessed by Fisher’s LSD test (P < 0.05). The results showed that the solids had 1.3-fold higher soluble solids content, 1.1-fold higher vitamin C, 2.5-fold total carotenoid content and 1.0-fold higher titratable acidity compared to juice. Oil No. 1 was characterized by a 1.88-fold bigger content of vitamin C and 2.9-fold higher titratable acidity. The total carotenoid content was 8.7% higher in oil No. 2. Oil No. 1 was less resistant to oxidative degradation because the induction period of this oil was shorter by 0.45 h and for a 26% higher amount of free fatty acids. However, a 12% higher peroxide content was found in oil No. 2. Oil No. 1 was brighter; the intensity of red and yellow colour of this oil was more intense.

Although the major components of various organs of sea buckthorn have been identified (particularly phenolic compounds), biological properties of many of these phytochemicals still remain poorly characterized. In this study, we focused on the chemical composition and biological activity of preparations that were obtained from sea buckthorn twigs and leaves. The objective was to investigate cytotoxicity of these preparations against human fibroblast line HFF-1, using MTT reduction assay, their anti- or pro-oxidant activities against the effects of a biological oxidant -H2O2/Fe—on human plasma lipids and proteins in vitro (using TBARS and carbonyl groups as the markers of oxidative stress). Antimicrobial activity of the tested preparations against Gram-positive (Staphylococcus aureus, S. epidermidis, Enterococcus faecalis) and Gram-negative bacteria (Escherichia coli, Pseudomonas aeruginosa), as well as against fungi (Candida albicans, C. glabrata) by the EUCAST-approved broth microdilution method, followed by growth on solid media, were also assessed. Our analysis showed significant differences in chemical composition and biological properties of the tested preparations (A–F). All tested preparations from sea buckthorn twigs (D–F) and one preparation from sea buckthorn leaves (preparation C) may be a new source of phenolic antioxidants for pharmacological and cosmetic applications.

The content of plant secondary metabolites is not stable, and factors such as the region/location effect and seasonal variations have an impact on their chemical composition, especially in parasitic plants. Research in this area is an important step in the development of quality parameter standards of medicinal plants and their finished products. The effects of the time and place of harvest and the host tree species on the chemical composition and antioxidant activity of mistletoe extracts were investigated. Statistical tools were used to evaluate the results of the spectrophotometric and LC-ESI-MS/MS studies of the phenolic composition and antioxidant activity. The investigations indicate that the qualitative and quantitative composition, influencing the biological activity of mistletoe extracts, largely depends on the origin of the plant. The mistletoe extracts exhibited a rich phenol profile and high antioxidant activity. The chemometric analysis indicated that mistletoe collected from conifers (Viscum abietis and Viscum austriacum) had the most advantageous chemical composition and antioxidant activity. Moreover, the chemical profile and biological activity of the plant material were closely related to the climatic conditions and location of the harvested plant. Higher levels of phenolic compounds and high antioxidant activity were found in extracts obtained from plant material collected in cold weather with the presence of snow and less sunshine (autumn–winter period).

The objective of the present study was to characterize chemical composition of hitherto unexamined aerial parts of Lactuca sativa var. angustana cv. Grüner Stern. In contrast to leafy and head varieties of the lettuces, asparagus lettuce grown in Europe is much less studied. Fractionation of a methanolic extract from leaves of L. sativa cv. Grüner Stern, supported with HPLC/DAD and 1H NMR analysis, led to the isolation and/or identification of numerous terpenoid and phenolic compounds, including five apocarotenoids—(-)-loliolide, (+)-dehydrovomifoliol, blumenol A, (6S,9S)-vomifoliol, and corchoionoside C; three sesquiterpene lactones; two lignans—((+)-syringaresinol and its 4-O-β-glucoside); five caffeic acid derivatives; and three flavonoids. Some of the compounds, to the best of our knowledge, have never been isolated from L. sativa before. Moreover, monolignols, phenolic acids and a tryptophan-derived alkaloid were found in the analyzed plant material. Stems, leaves and shoot tips of the asparagus lettuce were examined to assess their phenolics and sesquiterpene lactone content as well as DPPH scavenging activity. Another stem lettuce—L. sativa var. angustana cv. Karola, two cultivars of leafy lettuces and one species of wild lettuce—L. serriola, were also examined as a reference material using HPLC/DAD. The results have been discussed regarding our previous studies and the literature data available.

Co60 Gamma

Owing to its chemical composition and production chain, rice is susceptible to contamination by fungi. Among other techniques, the application of gamma radiation has been suggested as a method to ensure food safety. However, such radiation can alter the chemical composition of the food. Thus, the objective of the present work is to evaluate the centesimal composition, caloric value, pH, total titratable acidity, and coloration of polished white rice subjected to different doses of Co60 gamma radiation (0 kGy, 6.5 kGy, and 7.5 kGy). The results demonstrated that while gamma radiation did not cause significant alterations in the centesimal composition, caloric value, and titratable acidity of the rice, increasing doses substantially decreased the pH and intensified the coloration. Under controlled radiation conditions, a 6.5-kGy dose can render rice safe for consumption without significantly compromising its physical and physicochemical properties.

Traditional extraction techniques have lost their optimum performance because of rising consumer demand and novel technologies. In this regard, several techniques were developed by humans for the extraction of plant materials from various indigenous sources, which are no longer in use. Many of the techniques are not efficient enough to extract maximum plant material. By this time, evolution in extraction has led to development of various techniques including microfiltration, pulsed electric fields, high pressure, microwave assistance, enzyme assistance, supercritical fluid, subcritical fluid and ultrasonication. These innovations in food processing/extraction are known as “Green Food Processing”. These technologies were basically developed by focusing on three universal parameters: simplicity, energy efficiency and economy. These green technologies are practical in a number of different food sectors, mostly for preservation, inhibition of microorganisms, inactivation of enzymes and extraction of plant material. Like the others, ultrasonication could also be used for the said purposes. The primary objective of this review is to confine the potential use of ultrasonication for extraction of oils, pectin and phytochemicals by reviewing the literature systematically.

The principal aim of this study was to analyze the chemical composition and qualitative and quantitative variability of essential oils obtained from seven naturally grown populations of thePinus peuceGrisebach, Pinaceae in Kosovo. Plant materials were collected from three populations in the Sharri National Park and from four other populations in the Bjeshkët e Nemuna National Park, in Kosovo. Essential oils were obtained by steam distillation and analyzed by GC-FID (Gas Chromatography-Flame Ionization Detection) and GC-MS (Gas Chromatography-Mass Spectrometry). The results showed that the yield of essential oils (v/wdry weight) varied depending on the origin of population and the plant organs and ranged from 0.7 to 3.3%. In total, 51 compounds were identified. The main compounds wereα-pinene (needles: 21.6–34.9%; twigs: 11.0–24%),β-phellandrene (needles: 4.1–27.7; twigs: 29.0–49.8%), andβ-pinene (needles: 10.0–16.1; twigs: 6.9–20.7%). HCA (Hierarchical Cluster Analysis) and PCA (Principal Component Analyses) were used to assess geographical variations in essential oil composition. Statistical analysis showed that the analyzed populations are grouped in three main clusters which seem to reflect microclimatic conditions on the chemical composition of the essential oils.

The article presents the research results obtained during the development of the technology for production of combined sausages using a vegetable-derived additive – LUPISAN lupine flour from “OOO Protein PLUS” (St. Petersburg). Under the conditions of a deteriorating environmental situation and the increase in incidence of the population of the Russian Federation, it became necessary to create biologically complete functional food products with additional functions, useful nutritional and physiological characteristics, based on the integrated use of raw materials of animal and vegetable origin. The use of plant materials in the production of meat products allows not only enriching them with functional ingredients and increasing digestibility, but also obtaining products that meet physiological nutritional standards. Having a complex chemical composition, plants have a beneficial therapeutic effect on the human body. Research was carried out at the Department of Food Technology of the Don State Agrarian University, in the testing laboratory of the Shakhty branch of the Rostov “SBBZh” and at the meat processing plant “TaVr-Zimovniki”. Basing on the conducted comprehensive studies, the effectiveness of using vegetable protein supplement based on lupine flour “LUPISAN” in the production technology of semi-smoked sausages is substantiated. It is established that in terms of quality and safety, LUPISAN meets the requirements for additives of plant origin, it is a genetically unmodified, kosher product (has the appropriate certificates). It is dispersible both in oil and in water and can be used as a natural emulsifier without labeling with the index "E". The analysis of the chemical composition and nutritional value of flour from lupine indicates that the flour contains a significant amount of complete protein is 36–40%; in addition, a rather high content of dietary fiber is noted: dietary fiber is 30–35%. It is a strong antioxidant, it does not contain gluten and cholesterol; there are no inhibitors – substances that delay the digestion process and inhibit the absorption of beneficial substances by the body, and there are glycoproteins – substances that can replace insulin. An optimal dose of introducing a protein supplement based on lupine flour into sausage stuffing is proposed, which is 10% by weight of unsalted raw materials, which makes it possible to obtain a finished product with high organoleptic quality indicators and functional properties.
