Rheological and sensory properties of chickpea and quinoa pastes and gels for plant-based product development.

The aim of this study was to investigate the modification of mechanical, rheological, and sensory properties of chickpea pastes and gels by incorporating other ingredients (olive oil or quinoa flour), to develop plant-based alternatives that meet consumer demands for healthy, natural, and enjoyable food products. The pastes and gels were made with different amounts of chickpea flour (9% and 12%, respectively). For each product, a first set of products with different oil content and a second set with quinoa flour (either added or replaced) were produced. The viscoelastic properties of the pastes and the mechanical properties of the gels were measured. Sensory evaluation and preference assessment were carried out with 100 participants using ranking tests. The study found remarkable differences in rheological, mechanical, and sensory properties of chickpea products upon the inclusion of oil and quinoa flour. The addition of oil increased the viscosity and decreased the elastic contribution to the viscoelasticity of the pastes, while it improved the firmness and plasticity in gels. It also increased the creaminess and preference of both pastes and gels. Replacing chickpea with quinoa flour resulted in less viscous pastes and gels with less firmness and more plasticity. In terms of sensory properties, the use of quinoa as a replacement ingredient resulted in less lumpiness in the chickpea paste and less consistency and more creaminess in both the pastes and gels, which had a positive effect on preference. The addition of quinoa increased the viscosity of pastes and the firmness and stiffness of gels. It increased the consistency and creaminess of both pastes and gels. Quinoa flour and/or olive oil are suitable ingredients in the formulation of chickpea-based products. They contribute to the structure of the system, providing different textural properties that improve acceptance.

Research on seeds compression‐structural damage and castor oil extraction mechanism with in situ observation

AbstractCastor oil has attracted large attention for wide applications, including lubrication oil and bioenergy resources. Castor seeds mechanical pressing is widely used for oil extraction. To better research castor seeds mechanical‐structural damage behavior and oil extraction mechanism during extrusion, a self‐developed mechanical pressing test setup combined with in situ observation is built for oil output behavior. Influencing factors of working pressure, speed, temperature and creep time on oil outflow were investigated. The results indicate that seeds squeezing extraction can be divided into three stages, preloading, oil discharging, compressing consolidation stage, matching with pressing cake structural evolution. As working pressure increases, oil yield shows an upper parabola relation with pressure. When pressure exceeding 25 MPa, castor oil yield increasing tends to stabilize, reaching 38%. Speed effect showed down parabola relation on oil yield, opposite to stress factor. Creep time promoted oil output with upper parabola within 720 s. When temperature below 120°C, a linear increasing relation on oil yield presents. Oil yield decreases when above 120°C. This research provides in‐depth theoretical guidance for industrial castor oil extraction.Practical ApplicationsCastor seeds are rich in oil content. Extracted castor oil has been widely used for industrial applications such as biodiesel, lubricants, medicine.

In the research, castor seeds compression‐structural damage property and oil extraction mechanism were studied. Besides, the influence factors including compression pressure, speed, temperature and creep time are analyzed, working optimization for castor seeds oil extraction. The research provides important reference value for the mechanical pressing process and mechanical design of castor seeds in the practical applications.

3D printing of pickering emulsion gels of protein particles prepared by high pressure homogenization and heating

In this study, oil-in-water Pickering emulsion gels stabilized by soybean protein isolate microgel particles were prepared by a combination of high pressure homogenization and heating. These particles swiftly adsorbed onto the oil-water interface stabilizing drops. Cryo-SEM showed the formation of small droplets wrapped in a three-dimensional network structure of protein particles. Heating and increasing the oil content and particle concentration can improve the viscosity, energy storage modulus and gel strength of the system, which is conducive to improving the ability to 3D print these emulsions. The shear-thinning properties allow the system to be extruded smoothly through the nozzle with good printability. When the oil content was 60%, the accuracy and stability of the printed modeling reached 91.8% and 97.2%, respectively. In the future, the excellent properties of Pickering emulsion gel can be further utilized to load active ingredients, optimize and adjust the taste, and prepare food suitable for the elderly and other people with swallowing disorders with the help of 3D printing technology, and achieve the delivery of precise nutrition.

Fully ripe Omija (Schisandra chinensis Baillon) berry has been used for medicinal and edible purposes for a long time due to its various physiological activities. The seeds of Omija fruit are produced during the processing of the fruit, but are often discarded in the food industry. To increase the utilization of Omija seeds, this study investigated the differences in essential oil and lignan compositions between the pulp and seed. The yield of essential oil in whole berries was 1.33% based on dry weight, 0.91% in the pulp, and 2.65% in the seed, respectively. A total of 62 constituents were identified by GC and GC–MS analysis from the oils of the two parts. The major constituents were sesquiterpenes, such as α-ylangene, cuparene, alloaromadendrene, cis-lanceol, β-himachalene, and nootkatone. The content of these ingredients was higher in the seed than in the pulp. The most abundant lignan compounds in the berry were schizandrin, followed by γ-schizandrin, schizandrin A, and schizandrol B. The content of the four lignans in the seed was significantly higher than in the pulp. The seeds of Omija have higher contents of essential oils and lignan compounds compared to the pulp, making it necessary to explore approaches for utilizing them as food ingredients.

Unravelling the impact of drought and salt stresses on Thymus pannonicus: Morpho-physiological and biochemical insights

This research assesses the effects of drought and salt stresses applied individually or in combination on Thymus pannonicus, a resilient perennial herb native to the Pannonian vegetation region. Our experiment aimed to comprehensively evaluate morphological, physiological, and biochemical parameters of the thyme subjected to two levels of soil water capacity (SWC) - 70 % (control and salt stress) and 40 % (drought stress and combined stresses) - along with two salinity levels, 0 mM NaCl (control and drought stress) and 60 mM NaCl (salt stress and combined stresses). The plants exhibited significant responses to all the studied parameters under 40 % SWC in both treatments, demonstrating notable reductions in shoot and root parameters. In contrast, salt treatment at 60 mM had a minimal impact on growth. A stability in photosynthetic pigment composition was observed in all treatment, whereas a notable decrease (p < 0.05) in relative water content was seen in drought-stressed treatments compared to the to the control. Essential oil contents were higher in the control (0.91 ml/100g DW) but significantly declined (p < 0.05) under drought stress and combined stresses conditions (0.49 ml/100g DW and 0.53 ml/100g DW respectively). Particularly, the GC-MS analysis revealed a significant decrease (p < 0.05) in thymol and carvacrol content for the drought-stressed treatments. Substantial reductions were evident for the total polyphenol concentration and antioxidant capacity under the combined stress treatment, measuring 101.49 mg GAE/g DW and 106.57 AAE/g DW, respectively. Interestingly, the HPLC analysis indicated the highest levels of rosmarinic acid and caffeic acid in the drought-stressed treatment, while the lowest ones were recorded in the combined stress treatment. These findings indicated the responses of Thymus pannonicus to environmental stressors, emphasizing the need for further investigations for a comprehensive understanding of salinity effects.

Characteristics of Arabica and Robusta Spent Coffee Grounds Oil Extract with Different Solvents

Abstract High coffee consumption contributes to waste, such as spent coffee grounds (SCG). SCG contains up to 20 % oil, with the main oil content being linoleic and palmitic fatty acids. So, SCG has the potential to be used in valuable products. This study aims to characterise Arabica and Robusta SCG oil using maceration methods with different solvents (hexane, ethanol, and petroleum benzene) to obtain maximum coffee oil as an alternative. Arabica and Robusta SCG characterisation comprises the composition content, oil yield, fatty acid profile, and viscosity. The results showed that Arabica SCG oil yield was higher than Robusta, with hexane becoming the most efficient solvent to extract the oil, with 28,87% and 25,57%, respectively. The lowest free fatty acid (FFA) found in Arabica SCG oil extract using hexane is 1,95%, which consists of palmitic acid (9.41%), linoleic acid (5.37%), and stearic acid (4.7%). The highest viscosity is Arabica SCG oil extract using hexane, which is caused by the large amount of long-chain fatty acids extracted by the solvent, such as palmitic acid and linoleic acid. The FFA content of Arabica SCG oil extract using hexane has the potential to be edible oil (cooking oil) and biodiesel.

Quality assessment of commercially refined sunflower oil found in the market of Pokhara, Nepal

Sunflower oil is widely used for home cooking and the food industry. Food safety concerns are always there while consuming oil daily, so people want their purchased and consumed oil to be safe. The main aim of the research is to demonstrate and compare the data of different parameters obtained from laboratory experiments following the standard methods suggested by FSSAI-2016 (Food Safety and Standard Authority of India), A.O.A.C. (Association of Analytical Chemists) and the standard values given by D.F.T.Q.C. (Department of Food Technology and Quality Control), Nepal in 2075 B.S for edibleness of sunflower oil. Here, we show the standard methods to test the different parameters, i.e., moisture content, acid value, density, peroxide value, iodine value, saponification value, and unsaponifiable matter of edible sunflower oil. The dataset of preliminary and physiochemical analysis were within the limits of D.F.T.Q.C. standards for edible and refined sunflower oil, where moisture content was 0.05±0.01, refractive index was 1.4676±5.7735E-05, peroxide value was 2.65±0.098, acid value was 0.071±0.0026, iodine value was 128.02±0.007, saponification value was 189.92±1.094 and unsaponifiable matter was 2.53±0.7. This study concludes that all the selected samples of sunflower oils are in the permissible range according to the D.F.T.Q.C. directory (2075). It indicated that selected sunflower oil types have regulatory standards for public consumption concerning health risks under study from the Pokhara market.

Temperature and elevated CO2 alter soybean seed yield and quality, exhibiting transgenerational effects on seedling emergence and vigor.

Environmental conditions play a prime role in the growth and development of plant species, exerting a significant influence on their reproductive capacity. Soybean is sensitive to high temperatures during flowering and seed developmental stages. Little is known about the combined environmental effect of temperature and CO2 on seed yield and quality and its future generation. A study was conducted to examine the effect of temperature (22/14°C (low), 30/22°C (optimum), and 38/30°C (high)), and CO2 (420 ppm (ambient; aCO2) and 720 ppm (elevated; eCO2)) on seed yield, quality, and transgenerational seedling vigor traits of soybean cultivars (DS25-1 and DS31-243) using Soil-Plant-Atmospheric-Research facility. A significant temperature effect was recorded among yield and quality attributes. At high-temperature, the 100-seed weights of DS25-1 and DS31-243 declined by 40% and 24%, respectively, over the optimum temperature at aCO2. The harvest index of varieties reduced by 70% when exposed to high temperature under both aCO2 and eCO2, compared to the optimum temperature at aCO2. The seed oil (- 2%) and protein (8%) content altered when developed under high temperature under aCO2. Maximum sucrose (7.5%) and stachyose (3.8%) accumulation in seeds were observed when developed under low temperatures and eCO2. When the growing temperature increased from optimum to high, the seed oleic acids increased (63%), while linoleic and linolenic acids decreased (- 28% and - 43%, respectively). Significant temperature and CO2 effects were observed in progenies with the highest maximum seedling emergence (80%), lesser time to 50% emergence (5.5 days), and higher seedling vigor from parents grown at low-temperature treatment under eCO2. Exposure of plants to 38/30°C was detrimental to soybean seed yield, and eCO2 levels did not compensate for this yield loss. The high temperature during seed developmental stages altered the chemical composition of the seed, leading to an increased content of monounsaturated fatty acids. The findings suggest that parental stress can significantly impact the development of offspring, indicating that epigenetic regulation or memory repose may be at play.

Comparative Transcriptomic and Lipidomic Analysis of Fatty Acid Accumulation in Three Camellia oleifera Varieties During Seed Maturing.

Camellia oleifera, a major woody oil crop in China, produces tea oil rich in unsaturated fatty acids, earning it names like liquid gold and eastern olive oil. This study provides an integrated investigation of the transcriptome and lipidome within seeds at the maturing process across three C. oleifera varieties, revealing a significant relationship between fatty acid production and genes involved in lipid synthesis. Through transcriptomic analysis, 26,344 genes with varied expression were found. Functional enrichment analysis highlighted that pathways related to starch and sucrose metabolism, plant hormone signal transduction, and lipid accumulation were highly enriched among the differentially expressed genes. Coordinated high expression of key genes (ACCase, KAS I, KAS II, KAS III, KAR, HAD, EAR, SAD, LPAAT, LACS, DGAT, PDAT) during the late maturation stage contributes largely to high oil content. Additionally, expression variations of SAD and FADs among different varieties were explored. The analysis suggests that high expression of genes such as FAD3, FAD7, and FAD8 notably increased linolenic acid content. This research provides new insights into the molecular mechanisms of oil biosynthesis in C. oleifera, offering valuable references for improving yield and quality.

Non-destructive Evaluation of Oil Content and Carotene in Oil Palm Fresh Fruit Bunches Based on Optical Properties Using Partial Least Square (PLS)

Crude palm oil (CPO) is a raw material for making cooking oil that comes from palm oil, which is greatly influenced by the quality of oil palm fresh fruit bunches (FFB). Oil and carotene content in the FFB influence the quality of palm oil. The oil content is usually determined using a chemical method (Soxhlet extraction) which is time consuming and destructive. This research aimed to predict the oil and carotene content contained in oil palm FFB using partial least square (PLS). In this research, the sample used was the Tenera variety with a maturity of 140-160 day after anthesis (DAA) and 200-220 DAA. The nondestructive method involves recording images using an optical camera, which produces RGB and L*a*b* values. Results showed that PLS predicts the relationship between optical properties and oil and carotene content in palm oil. Non-destructive prediction results using PLS provided consistently correlation of L*a*b* values with estimated oil and carotene content in the FFB. Keywords: Non-destructive, Optical properties, Fresh fruit bunch, Oil palm.

YIELD AND QUALITY CHARACTERISTICS OF SUNFLOWER (Helianthus annuus L.) CULTIVARS BY DIFFERENT SOWING DATES

A field trial was initiated to ascertain the optimal sowing date for five distinct sunflower cultivars in Turkey’s Mardin Province. The trial scrutinised various parameters including plant height, head diameter, seed yield, protein content, oil content and oil yield. The first sowing produced the highest seed yields (3484 kg ha−1), with the Şems (3255 kg ha−1) and Zuhat (3157 kg ha−1) cultivars producing the highest values. The highest overall oil content was achieved in the second sowing (31.7%) and in the Zuhat cultivar (34.6%). The highest mean oil yields were observed in the Zuhat cultivar (1096 kg ha−1) and in the first sowing (1084 kg ha−1). There was a general decrease in yield as the sowing date was delayed. Winter sowing is suggested for the Zuhat cultivar. If possible, the second sunflower crop should be sown shortly following the harvest of the main crop.

Among the different micronutrient treatment combinations, different micronutrients using in T1 treatment were more effective for the reducing the incidence of sucking insect pests on sunflower. In the term of effect of micronutrients, T1= Recommended doses of Urea, TSP and MoP + Boron @ 7.0 gm/ Plot+ ZnSo4 @ 8.4 gm/ Plot; was an eco-friendly pest management practice for sunflower by which one can significantly reduce pest infestation without use of any chemical insecticides.

Genome-wide analysis of HACD family genes and functional characterization of GhHACD2 for very long chain fatty acids biosynthesis in Gossypium hirsutum

Cotton (Gossypium spp.) not only serves as a primary textile fiber crop but also as a vital oilseed crop. It stands as the world’s fifth-largest oil crop and is rich in essential fatty acids. At present, the mechanisms underlying the biosynthesis of cottonseed oil have been extensively studied in cotton. 3-Hydroxyacyl-CoA dehydratase (HACD) is the third rate-limiting enzyme in the elongase complex, which plays a critical role in the biosynthesis of Very Long Chain Fatty Acids (VLCFA). However, the members of the HACD family and their roles in cottonseed oil remain uncharacterized in cotton. This study identified that G. arboreum and G. raimondii have two HACD genes, while four HACD genes exists in G. hirsutum, and G. barbadense. The phylogenetic relationships of the 12 HACD genes from the four cotton species further divided them into two subfamilies. Gene structure and conserved motif analysis revealed that members of the HACD family were relatively conserved during the evolution of cotton, but members within the same subfamily exhibited more similar structures. Homology and collinearity analysis suggest whole-genome duplication/segmental duplication may be a key factor in the amplification of the cotton HACD gene family. The qRT-PCR analysis of high-oil and low-oil genotype found significant differences in the expression levels of GhHACD1-4, which indicates GhHACD1-4 is expected to participate in the lipid oil biosynthesis process. Subcellular localization experiments confirmed the presence of the GhHACD2 inendoplasmic reticulum. The KEGG pathway enrichment analysis of co-expressed genes of GhHACD1 and GhHACD2 genes were conducted to confirm their potential involvement in fatty acid elongation and oil biosynthesis. Furthermore, transgenic overexpression analysis of GhHACD2 caused a 5.02% decrease in oil content compared with the control in yeast, while the levels of C28:0, C30:0, and VLCFAs were significantly improved. This study characterizes HACD gene family members in cotton and provides rich genetic resources for increasing cottonseed oil content and improving the nutritional value of cottonseed oil.
