functional food, beverage, cosmetic and specialized delivery-system applications.<\/p>\n<p>Available formats include 99% high-purity powder, 50% and 20% standardized grades, 10% water-soluble Trans-Resveratrol, granular Trans-Resveratrol and liposomal Trans-Resveratrol.<\/p>\n<p>The correct specification depends on the finished-product dosage, processing method, powder-handling requirements, dispersion behavior and stability profile. Trans-Resveratrol should therefore be selected according to the final application rather than assay alone.<\/p>\n<h2>Product Identity and Supply Range<\/h2>\n<ul>\n<li><strong>Product name:<\/strong> Trans-Resveratrol<\/li>\n<li><strong>CAS Number:<\/strong> 501-36-0<\/li>\n<li><strong>Molecular formula:<\/strong> C<sub>14<\/sub>H<sub>12<\/sub>O<sub>3<\/sub><\/li>\n<li><strong>Molecular weight:<\/strong> 228.24 g\/mol<\/li>\n<li><strong>Origin:<\/strong> Fermentation-derived<\/li>\n<li><strong>Available assay levels:<\/strong> 99%, 50%, 20% and 10% water-soluble<\/li>\n<li><strong>Available forms:<\/strong> Powder, water-soluble powder, granules and liposomal form<\/li>\n<li><strong>MOQ:<\/strong> 1 kg<\/li>\n<\/ul>\n<h2>Core Product Advantages<\/h2>\n<p>Ureda Naturals combines a fermentation-derived production route with controls for chemical purity, visual appearance, powder performance and application flexibility.<\/p>\n<ul>\n<li>Fermentation-derived production using a GRAS-recognized production strain;<\/li>\n<li>High-purity specifications with assay controlled at 99.0\u2013101.0% on a dry basis;<\/li>\n<li>Purity targets of \u226599.5% for selected high-purity specifications;<\/li>\n<li>All-trans profile with cis-resveratrol and emodin not detected in the high-purity specification;<\/li>\n<li>Ultra-white grade with a whiteness value above 90;<\/li>\n<li>Controlled bulk density, tapped density and particle size;<\/li>\n<li>Residual ethanol controlled at \u22641,000 ppm;<\/li>\n<li>Control of pesticide residues and plasticizer residues;<\/li>\n<li>Heavy-metal and microbiological testing;<\/li>\n<li>C-14 documentation for origin assessment;<\/li>\n<li>Powder, water-soluble, granular and liposomal formats for different formulation processes.<\/li>\n<\/ul>\n<h2>Production Route Comparison<\/h2>\n<div class=\"ureda-table-wrap ureda-route-table\">\n<table>\n<thead>\n<tr>\n<th scope=\"col\">Test Item<\/th>\n<th scope=\"col\">Fermentation-Derived Trans-Resveratrol<\/th>\n<th scope=\"col\">Chemically Synthesized Trans-Resveratrol<\/th>\n<th scope=\"col\">Plant-Extracted Trans-Resveratrol<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<th scope=\"row\">Appearance<\/th>\n<td>White or off-white powder<\/td>\n<td>Off-white or grayish-white powder<\/td>\n<td>Light yellow to brown powder<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Odor<\/th>\n<td>Slight odor<\/td>\n<td>Pungent odor<\/td>\n<td>Pungent odor<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Assay<\/th>\n<td>\u226599%<\/td>\n<td>\u226599%<\/td>\n<td>50\u201398%<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Maximum single impurity<\/th>\n<td>\u22640.10%<\/td>\n<td>\u22640.10%<\/td>\n<td>Multiple impurities at or above 0.10%<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Total impurities<\/th>\n<td>\u22640.5%<\/td>\n<td>\u22640.5%<\/td>\n<td>Multiple impurity components may be present<\/td>\n<\/tr>\n<tr>\n<th scope=\"row\">Solvent residues<\/th>\n<td>Ethanol \u22641,000 ppm;

A 99% powder, a 10% water-soluble grade, a granule and a liposomal system require different process controls.<\/p>\n<\/details>\n<details open=\"open\">\n<summary>How do 99%, 50%, 20% and 10% grades change the formula?<\/summary>\n<p>They change the raw-material quantity required to deliver the same active dose. This affects fill weight, carrier level, capsule capacity, powder volume, beverage solids and finished-product uniformity.<\/p>\n<\/details>\n<details open=\"open\">\n<summary>Why may 99% Trans-Resveratrol powder be unsuitable for a beverage?<\/summary>\n<p>High-purity powder has limited native water solubility. It may initially disperse but later produce haze, sediment or recrystallization. The 10% water-soluble form is a more suitable starting point for beverage development.<\/p>\n<\/details>\n<details open=\"open\">\n<summary>Why does passing 80 mesh not guarantee blend uniformity?<\/summary>\n<p>Mesh size only describes sieve passage. Particle shape, density, electrostatic behavior, agglomeration, transfer distance and mixing conditions also affect uniformity.<\/p>\n<\/details>\n<details open=\"open\">\n<summary>Why should cis-resveratrol, emodin and total impurities be reviewed separately?<\/summary>\n<p>Assay confirms the amount of Trans-Resveratrol, while related-substance testing describes the composition of the remaining material. Reviewing both provides a more complete assessment of chemical consistency.<\/p>\n<\/details>\n<details open=\"open\">\n<summary>Does an ultra-white appearance prove higher chemical purity?<\/summary>\n<p>No. Ultra-white appearance is valuable when the finished product requires a lighter color, but appearance does not replace HPLC assay, identity testing or impurity testing.<\/p>\n<\/details>\n<details open=\"open\">\n<summary>What changes when liposomal Trans-Resveratrol is selected?<\/summary>\n<p>The quality review expands beyond assay and purity. Active loading, particle size, encapsulation efficiency, leakage, oxidation and storage stability become important performance parameters.<\/p>\n<\/details>\n<details open=\"open\">\n<summary>How should cosmetic formulations protect Trans-Resveratrol?<\/summary>\n<p>Control pH, heat, oxygen, light and addition sequence.
