IDENTIFICATION AND ANALYSIS OF ACTIVE CAROTENOID COMPOUNDS FROM ENTAWAK FRUIT (ARTOCARPUS ANISOPHYLLUS)

— Isolation and identification of active compounds from mentawak fruit (Artocarpus Anisophyllus) used a plant determination test to determine the plant content. Furthermore, the extraction process was carried out to obtain a crude extract of carotenoid pigments by maceration method using n-hexane as solvent. Furthermore, the obtained macerate was carried out by phytochemical tests to determine the content of the active compounds. The TLC test was carried out to confirm the presence of a positive group of compounds on phytochemical screening, and to determine the chromatographic profile of the extract. The identification results showed that the phytochemicals showed that the active compounds contained in macerate were alkaloids, flavonoids, tannins and saponins. The KLT test results obtained an Rf value of 0.875. While the total carotenoid content using a spectrophotometer UV-Vis is 958 µg/ml.

Carotenoid Cocktail Produced by An Antarctic Soil Flavobacterium with Biotechnological Potential

Carotenoids are highly important in pigmentation, and its content in farmed crustaceans and fish correlates to their market value. These pigments also have a nutritional role in aquaculture where they are routinely added as a marine animal food supplement to ensure fish development and health. However, there is little information about carotenoids obtained from Antarctic bacteria and its use for pigmentation improvement and flesh quality in aquaculture. This study identified carotenoids produced by Antarctic soil bacteria. The pigmented strain (CN7) was isolated on modified Luria–Bertani (LB) media and incubated at 4 °C. This Gram-negative bacillus was identified by 16S rRNA analysis as Flavobacterium segetis. Pigment extract characterization was performed through high-performance liquid chromatography (HPLC) and identification with liquid chromatography–mass spectrometry (LC–MS). HPLC analyses revealed that this bacterium produces several pigments in the carotenoid absorption range (six peaks). LC–MS confirms the presence of one main peak corresponding to lutein or zeaxanthin (an isomer of lutein) and several other carotenoid pigments and intermediaries in a lower quantity. Therefore, we propose CN7 strain as an alternative model to produce beneficial carotenoid pigments with potential nutritional applications in aquaculture.

The Fortification Effects of Sea Grapes (Caulerpa racemosa) Powder on Color and Sensory of Hakau Dim Sum Wrappers

Sea grapes (Caulerpa racemosa) are green seaweeds that include containing dietary fiber, antioxidant compounds, and natural dyeing colours such as chlorophyll and carotenoid pigments. Sea grapes’ green tint, when ground into powder, has the potential to be used as a coloring agent. It can be used as an alternative dyeing agent and product diversification on hakau dim sum wrappers. The purpose of this study was to determine how adding sea grapes powder affected the physical properties (color and folding test) and sensory attributes (time-intensity) of hakau dim sum wrappers. The research was conducted by manufacturing sea grape powder and the wrappers by hand. Caulerpa racemosa was added in various concentration (0%; 1.5%; 3%; 4.5%; and 6%) (w/w). The dough was molded with a thickness of no.5 pasta maker with 8 cm diameter. The wrappers were physically tested and steamed for 15 minutes for sensory testing. As a result, wrappers fortified with sea grape powder show green colour and stand up the transparent characteristics. Lightness (L*) and redness (a*) decreased with increasing concentration of sea grape powder which indicated dark green wrappers color. Sea grape powder affected raw wrappers in the folding test. Time-intensity evaluation looked at the gelatinized flour flavor and sea grapes flavor. The result shows the gelatinized flour flavor reached the highest peak in the control wrappers, while the concentration of 6% had the highest intensity of sea grapes flavor and the lowest gelatinized flour flavor. In conclusion, the addition of sea grape powder resulted in a transparent green dim sum wrapper, decreased folding score for raw and the sea grapes flavor was more dominant than the gelatinized flour flavor.

Identification and analyses of the chemical composition of a naturally occurring albino mutant chanterelle

White chanterelles (Basidiomycota), lacking the orange pigments and apricot-like odour of typical chanterelles, were found recently in the Canadian provinces of Québec (QC) and Newfoundland & Labrador (NL). Our phylogenetic analyses confirmed the identification of all white chanterelles from NL and QC as Cantharellus enelensis; we name these forma acolodorus. We characterized carotenoid pigments, lipids, phenolics, and volatile compounds in these and related chanterelles. White mutants of C. enelensis lacked detectable β-carotene, confirmed to be the primary pigment of wild-type, golden-orange individuals, and could also be distinguished by their profiles of fatty acids and phenolic acids, and by the ketone and terpene composition of their volatiles. We detected single base substitutions in the phytoene desaturase (Al-1) and phytoene synthase (Al-2) genes of the white mutant, which are predicted to result in altered amino acids in their gene products and may be responsible for the loss of β-carotene synthesis in that form.

Assessment of Lycopene Derived Fresh and Processed Tomato Products on Human Diet in Eliminating Health Diseases

Tomato which is scientifically known as Lycopersicon esculentum and basically belonging to the Solanaceae family is categorized as one of the most essential horticultural crops. The red colour in tomatoes and other fruits is primarily due to the presence of a carotenoid pigment particularly lycopene which acts as a phytochemical. Higher concentrations of lycopene pigment are particularly found in fruits like tomatoes, watermelon, pink grapefruit, pink guava, red bell pepper, sea buckhorn, wolfberry, and rosehip. Lycopene plays a fundamental role in the process of biosynthesis of several carotenoid pigments specifically available in two forms; Hydrocarbon carotenoids and Xanthophylls thereby responsible for imparting red, yellow, and orange color in addition to photosynthesis and photo-protection in terms of plants, algae and other photosynthetic organisms. It acts as a potential antioxidant among the entire carotenoid pigments because of its characteristics involving strong color and anti-toxicity properties. Vitamins enriched beta carotene provitamin A, and Ascorbic acid in the form of edible compounds have been abundantly found in tomatoes. Daily intake of lycopene through consumption of tomato and processed tomato products helps in reducing the risk of chronic diseases particularly cancer and cardiovascular diseases. Epidemiological studies have indicated the importance of lycopene in eliminating the risk of human diseases thereby preventing it from deterioration of health. Based on the chemical structure of lycopene, it exists in a thermodynamically stable form thereby exhibiting trans-configuration. In this manuscript, major emphasis highlighted in involving an intake of carotenoid enriched fruits and vegetables for further controlling and reducing the risk of occurrence of human diseases has been reviewed. In addition, significance of manufacturing of value added products and its consumption in the form of tomato oil, non-alcoholic flavored drink etc. has also been reviewed. Authentic information in terms of the addition of lycopene in a daily balanced diet either fresh or processed tomato products along with its functions involving the singlet oxygen quenching ability, as well as benefits of consuming lycopene derived fruits has been reviewed in this manuscript.

Exogenous pigments shield microorganisms from spaceflight-induced changes

Research has indicated that pigments commonly produced by microorganisms may be protective against the environmental stresses inherent to spaceflight. However, few studies have directly tested the protective capabilities of microbial pigments applied externally as shielding materials. In this study, liquid cultures of Bacillus subtilis were shielded by various pigment solutions, and solid media cultures of Bacillus subtilis were co-inoculated with the highly pigmented microorganisms Aspergillus niger and Neurospora crassa. These experiments were conducted in a compact, automated payload aboard the International Space Station (ISS) interior for 30 days. Post-flight phenotypic analyses of liquid cultures showed that solutions of carotenoid pigments were effective at minimizing detrimental effects of spaceflight. Elevated growth rate was observed for solid cultures, and distinct morphology changes were identified in both liquid and solid samples and quantified as markers of spaceflight-induced stress. These findings collectively progress our understanding of microbial pigments for the development of space-related applications.

Antibiotic treatment increases yellowness of carotenoid feather coloration in male greenfinches (Chloris chloris)

Carotenoid plumage coloration is an important sexually selected trait in many bird species. However, the mechanisms ensuring the honesty of signals based on carotenoid pigments remain unclear. It has recently been suggested that intestinal integrity, which is affected by gut parasites and microbiota and influences nutrient absorption and acquisition, mediates the relationship between carotenoid ornamentation and individual quality. Here, we test whether carotenoid plumage coloration in greenfinches (Chloris chloris) is affected by the treatment of an antibiotic or an antiparasitic drug. We captured wild greenfinches (N = 71) and administered anticoccidial medication toltrazuril (TOLTRA) to one group, antibiotic metronidazole (METRO) to the second group to target trichomonosis, and the third group received no medication. In the METRO group, feathers grown during the experiment had significantly higher chroma of yellow parts, but there was no effect of TOLTRA on feather chroma. The results suggest that METRO increased the efficiency of carotenoid modification or deposition to the feathers rather than nutrient acquisition and/or freed energy resources that could be invested in coloration. Alternatively, though not measured, METRO might have affected microbial community and host physiology as microbial metabolites can modulate mitochondrial and immune function.
