Characterization of Confectionery Spreadable Creams Based on Roasted Sunflower Kernels and Cocoa or Carob Powder

CSpreadable creams are solid-oil suspensions, a mix of fats represents the oil phase, the dispersed phase consisting usually of sugar, cocoa powder, milled and roasted nuts, dried milk and whey. For improving the viscosity of the final product emulsifiers are used, most common being lecithin and mono and diglycerides. The present paper refers to a spreadable confectionery product group, creamy, proper to be eaten as it is, as well as spread on a bread slice or as a filling for cookies or chocolate cream. According to this work, the following ingredients were used: roasted sunflower kernels, sugar, palm oil, cocoa or carob powder and lecithin. The obtained product can be consumed also by persons who suffer from allergies, due the fact that sunflower seeds were replacing the peanuts or almond, the ingredients known as allergens and which are usually used in the technological process of obtaining these creams. The purpose of this study was to characterize the obtaining confectionery spreadable creams based on sunflower kernels, cocoa or carob powder. It was determined the chemical composition of the prototypes obtained, a spreadable cream having no cocoa or carob, one with cocoa and one with carob powder. The antioxidant capacity and total phenolic content of the obtained samples were also assessed

Food Fortification through Innovative Technologies

The chapter aims to approach food fortification naturally as a result of the need for nutritional improvement and therefore underlines sustainable activities that would facilitate effective fortification. The need to fortify food is due to the close link between human, health, and food. The WHO and FAO and other internationally recognized organizations have recognized that there are over 2 billion people worldwide suffering from a variety of micronutrient deficiencies. The interest in the fortification of foods is largely due to bioactive compounds, such as vitamins, minerals, sugars, organic acids, dietary fiber, phenolic compounds, essential amino acids, and antioxidants. The most effective and accessible way of securing the population with vitamins and micronutrients is to fortify additional food and consumer products daily. At the same time, the technology for the fortification of bakery products will also be presented

Bacillus thuringiensis PM25 ameliorates oxidative damage of salinity stress in maize via regulating growth, leaf pigments, antioxidant defense system, and stress responsive gene expression

Soil salinity is the major abiotic stress that disrupts nutrient uptake, hinders plant growth, and threatens agricultural production. Plant growth-promoting rhizobacteria (PGPR) are the most promising eco-friendly beneficial microorganisms that can be used to improve plant responses against biotic and abiotic stresses. In this study, a previously identified B. thuringiensis PM25 showed tolerance to salinity stress up to 3 M NaCl. The Halo-tolerant Bacillus thuringiensis PM25 demonstrated distinct salinity tolerance and enhance plant growth-promoting activities under salinity stress. Antibiotic-resistant Iturin C (ItuC) and bio-surfactant-producing (sfp and srfAA) genes that confer biotic and abiotic stresses were also amplified in B. thuringiensis PM25. Under salinity stress, the physiological and molecular processes were followed by the over-expression of stress-related genes (APX and SOD) in B. thuringiensis PM25. The results detected that B. thuringiensis PM25 inoculation substantially improved phenotypic traits, chlorophyll content, radical scavenging capability, and relative water content under salinity stress. Under salinity stress, the inoculation of B. thuringiensis PM25 significantly increased antioxidant enzyme levels in inoculated maize as compared to uninoculated plants. In addition, B. thuringiensis PM25-inoculation dramatically increased soluble sugars, proteins, total phenols, and flavonoids in maize as compared to uninoculated plants. The inoculation of B. thuringiensis PM25 significantly reduced oxidative burst in inoculated maize under salinity stress, compared to uninoculated plants. Furthermore, B. thuringiensis PM25-inoculated plants had higher levels of compatible solutes than uninoculated controls. The current results demonstrated that B. thuringiensis PM25 plays an important role in reducing salinity stress by influencing antioxidant defense systems and abiotic stress-related genes. These findings also suggest that multi-stress tolerant B. thuringiensis PM25 could enhance plant growth by mitigating salt stress, which might be used as an innovative tool for enhancing plant yield and productivity

<i>Stachys lavandulifolia</i> Populations: Volatile Oil Profile and Morphological Diversity

The morphological and essential oil diversity of Stachys lavandulifolia populations from the west and northwest of Iran were evaluated. The results showed a significant difference between the populations for nearly all the evaluated traits. The broadest variation ranges were recorded for the auxiliary shoot length, leaf length in the main branch, and the number of flowers in the inflorescences. Furthermore, cluster analysis divided 13 populations into four separate groups. GC/MS analysis verified the presence of 28 components comprising up to 94/4% of the oils. The dominant constituents were α-pinene (1.07–34.87%), (E)-caryophyllene (0.45–25.99%), germacrene D (3.36–20.61%), Δ-cadinene (2.82–19.90%), bicyclogermacrene (1.72–12.08%) α-terpineol (0–11.86%), α-muurolol (0.31–11.50%), p-cymene (0.67–9.67%), β-elemene (0.63–9.31%), and sabinene (0.32–6.29%). The results revealed that natural habitats and the related geo-climatological cues influenced morphological traits and oil composition. Considering the substantial environmental variations and the broad diversity, there would be a rich selection pool for the traits of interest. The populations are a step forward in the breeding programs for the highlighted essential oil constituents needed by the pharmaceutical and related industries. Furthermore, with the future comparative study of the populations from all Iranian territories and the neighboring countries, we will have a realistic idea of the coming conservational and exploitation programs

Plants’ Physio-Biochemical and Phyto-Hormonal Responses to Alleviate the Adverse Effects of Drought Stress: A Comprehensive Review

Water, a necessary component of cell protoplasm, plays an essential role in supporting life on Earth; nevertheless, extreme changes in climatic conditions limit water availability, causing numerous issues, such as the current water-scarce regimes in many regions of the biome. This review aims to collect data from various published studies in the literature to understand and critically analyze plants’ morphological, growth, yield, and physio-biochemical responses to drought stress and their potential to modulate and nullify the damaging effects of drought stress via activating natural physiological and biochemical mechanisms. In addition, the review described current breakthroughs in understanding how plant hormones influence drought stress responses and phytohormonal interaction through signaling under water stress regimes. The information for this review was systematically gathered from different global search engines and the scientific literature databases Science Direct, including Google Scholar, Web of Science, related studies, published books, and articles. Drought stress is a significant obstacle to meeting food demand for the world’s constantly growing population. Plants cope with stress regimes through changes to cellular osmotic potential, water potential, and activation of natural defense systems in the form of antioxidant enzymes and accumulation of osmolytes including proteins, proline, glycine betaine, phenolic compounds, and soluble sugars. Phytohormones modulate developmental processes and signaling networks, which aid in acclimating plants to biotic and abiotic challenges and, consequently, their survival. Significant progress has been made for jasmonates, salicylic acid, and ethylene in identifying important components and understanding their roles in plant responses to abiotic stress. Other plant hormones, such as abscisic acid, auxin, gibberellic acid, brassinosteroids, and peptide hormones, have been linked to plant defense signaling pathways in various ways
