To enhance the curcumin absorption by oral administration, liposome-encapsulated (LEC) was prepared from commercially available lecithins (SLP-WHITE and SLP-PC70) examined for its interfacial biochemical properties. A LEC 5 wt % of SLP-PC70 2.5 gave a good dispersibility with 68.0% encapsulation efficiency curcumin, while those SLP-WHITE did not. Moreover, resulting using confirmed to be composed small unilamellar vesicles diameter approximately 263 nm. The then effect on bioavailability in...
Aloe vela leaf gel extract (AGE) are widely used as cosmetic and pharmaceutical ingredients because of its versatile skin care properties. In order to enhance the bioavailability AGE, liposomes encapsulating AGE were prepared examined for their interfacial biochemical The from a soybean lecithin (SLP-WHITE, 1.0 wt%) by Bangham method gave relatively good trapping efficiency up concentration 0.5 wt%. stable then wt% SLP-WHITE different concentrations mechanochemical using homogenizer...
Abstract Sugarcane ( Saccharum officinarum L.) wax that contains policosanol (a mixture of long‐chain alcohols), is widely known to have beneficial effects on human health. In order investigate differences in the composition and content sugarcane different cultivars, wax, policosanol, aldehyde eight cultivars were examined. The was analyzed using HPLC coupled with an evaporative light scattering detector (ELSD). waxes comprised 55–60% sterol esters, 32–40% alcohol, small amounts TAG, acid,...
The volatile profiles of palm sugar, a traditional sweetener used in Southeast Asia, vary according to its geographic and botanical origin. This study investigated the organic components (VOCs) Indonesian Malaysian sugars derived from Arenga pinnata, Nypa fruticans, Cocos nucifera using solid-phase microextraction-GC-MS MS-e-nose analyses. A total 42 compounds were detected, including 12 Maillard reaction products, 10 esters, 8 alcohols, 5 ketones, 3 carboxylic acids, phenols, 1 aldehyde....
Although postmortem aging of pork improves its umami taste when roasted, the relationship between roasted aroma and has not been investigated. Therefore, in this study, we investigated role taste-related metabolites composition meat during aging. Comprehensive metabolomic analyses volatile organic compounds aged were conducted by gas chromatography-time-of-flight mass spectrometry. Taste-related metabolites, including amino acids, sugars, fatty nucleic accumulated with age. Among detected...
Flavor and nutritional quality has been negatively impacted during the course of domestication improvement cultivated tomato (Solanum lycopersicum). Recent emphasis on consumers emphasized breeding strategies that focus flavor-associated chemicals, including sugars, acids, aroma compounds. Carotenoids indirectly affect flavor as precursors compounds, while chlorophylls contribute to sugar production through photosynthesis. However, relationships between these pigments content are still...
Introduction: Lung cancer is recognized as a highly lethal disease, demanding swift and accurate solutions. Previous analysis showed the cytotoxic impact of Callyspongia aerizusa (C. aerizusa) extract containing ergost-22-en-3-one ergost-7-en3-ol against A549 lung cells, with an IC 50 value 9.38 μg/mL. However, did not have cytotoxicity towards Het-1A esophagus epithelial cells. Several reviews also validated upregulation pro-apoptotic molecules inhibition anti-apoptotic linked to...
Processed brown sugar is produced by combining non-centrifugal cane (NCS), raw sugar, and molasses. The present study aimed to examine the effects of NCS blending (10%:90%, 50%:50%, 75%:25%, 90%:10%) on color traits, non-volatile volatile compounds, retronasal aroma release, sensory profiles processed hence, its flavor quality. International Commission for Uniform Methods Sugar Analysis (ICUMSA) index +L* (brightness) +b* (yellowness) spaces were gradually altered upon addition with strong...
Citrus peels are important sources of various pleasant aroma compounds and valuable bioactive substances. To investigate differences in the composition content Shiikuwasha (Citrus depressa Hayata) from different cultivation lines, volatile components, flavanones, polymethoxylated flavones (PMFs) four lines was examined. The components cold-pressed extracts analyzed using gas chromatography–flame ionization detection chromatography–mass spectrophotometry. contained mainly monoterpene...
Abstract In this study, 2 types of solidified noncentrifugal brown sugars (W‐NCS and P‐NCS) were prepared from the whole stalk separated pith, respectively, raw sugarcane ( Saccharum officinarum L.). These products discriminated in terms their quality attributes, including color, minerals composition, taste, aroma, antioxidant activity. The color P‐NCS was clearly different compared with that W‐NCS a difference value (Δ E * ) 9.36. There no composition between sugar, which led to very...
Shiikuwasha (Citrus depressa Hayata) essential oil (SEO) extracted from fruit pulp contains two major volatile components, limonene and γ-terpinene (56.56-57.31 24.41-24.98%, respectively). In this study, we showed that the aroma streams of SEO, limonene, exhibited significant physiological stress amelioration effects in nine healthy female panelists tested a 30-min visual display task. While SEO administration significantly reduced work errors by 15 min compared to odorless control...
Citrus depressa Hayata is a small-fruit citrus species; it indigenous to Kagoshima, Okinawa, and Taiwan. The metabolites volatile organic compounds (VOCs) that affect the flavor of its fruits have not been investigated based on geographical origin. In present study, we metabolite VOC profiles 18 C. cultivation lines from these regions. Multivariate analysis revealed differences in origins; variations sugar, sugar alcohol, amino acid contents were also observed. Fruits Kagoshima Okinawa had...
Abstract: The flavedo peel extracts of unripe Shiikuwasha ( Citrus depressa Hayata) fruits were extracted using steam distillation (SD) or a cold‐press (CP) system. Volatile aroma content and composition determined gas chromatography (GC) each compound was identified chromatography‐mass spectrophotometry (GC‐MS). major constituents the monoterpene hydrocarbons (91.75–93.75%[709.32–809.05 mg/100 g fresh peel]) including limonene (43.08–45.13%[341.46–379.81 peel]), γ‐terpinene...
Shiikuwasha pulp is an important raw material for producing citrus essential oils. The volatile aroma composition of oil was evaluated using gas chromatography (GC) methods, and its profile assessed GC-olfactometry with extended extract dilution analysis (AEDA) technique in regard to alterations odor strength sensorial perception throughout serial steps. comprised a mixture 55 compounds, including monoterpene hydrocarbon, sesquiterpene alcohol, aldehyde, ester, oxide compounds. predominant...
Abstract The purpose of this study was to predict the total phenolic content (TPC) and flavonoid (TFC) in several horticultural commodities using near-infrared spectroscopy (NIRS) combined with machine learning. Although models are typically developed for a single product, expanding coverage model can improve efficiency. In study, 700 samples were used, including varieties shallot, cayenne pepper, red chili. results showed that TPC yielded R 2 cal, root mean squares error calibration set,...
Non-centrifugal cane sugar (NCS) is an unrefined dehydrated form of syrup produced worldwide. To date, there a lack differentiation in the key nutrients and flavor qualities NCS products among countries, which makes it difficult for interested parties to select NCSs suitable their needs.
