Uncompromising Quality: SRBio’s Manufacturing Excellence

1. Precision Quality Control

Note: Polyphenol and anthocyanin content varies by grape variety (red/black/purple grapes provide higher levels; green/white grapes provide lower levels). Custom specifications available upon request.

2. Advanced Processing Technology

Superior Raw Material Sourcing:

• Origin: Premium grapes sourced from certified farms known for optimal polyphenol content, vibrant color, and nutrient density

• Variety Selection: Blend of seeded and unseeded varieties of green, red, and blue-black grapes in proportions representative of an entire annual crop, ensuring consistent polyphenol profiles including catechin, epicatechin, quercetin, kaempferol, isorhamnetin, malvidin, peonidin, cyanidin, and resveratrol

• Harvesting: Fruits harvested at peak ripeness to maximize natural sugar content, anthocyanin levels, and polyphenol concentration

• Authentication: Supplier qualification audits and pesticide residue analysis (GC-MS, 400+ compounds) ensure raw material purity

Freeze-Drying Technology (Lyophilization):

• Preservation of Nutrients: Freeze-drying at low temperatures (-30°C to -50°C) under vacuum preserves >95% of heat-sensitive nutrients, including anthocyanins, resveratrol, and other bioactive polyphenols. Studies confirm that freeze-dried grape powders retain more color, superior quality, and higher nutrient levels compared to sun-dried alternatives.

• Superior Quality vs. Spray-Drying: Unlike high-temperature spray-drying, which can degrade heat-sensitive polyphenols and volatile aroma compounds, freeze-drying maintains the fruit’s original vibrant purple-red color, natural grape aroma, and complete nutritional profile.

• Instant Solubility: The porous structure of freeze-dried powder ensures rapid and complete rehydration in water, juices, smoothies, and other liquid formulations.

• Scientific Standardization: Our freeze-dried grape powder is chemically standardized for major polyphenols and antioxidants, enabling reproducible results for both human clinical trials and animal studies. An appropriate placebo powder (matched for caloric value, color, texture, and flavor) is available for research applications.

Alternative Processing Options:

• Spray-Dried Powder: Cost-effective option for applications where high heat tolerance is acceptable; often uses maltodextrin or gum systems as carriers for flowability and stability.

• Juice Powder Concentrate: Concentrated formats available for intensified flavor and nutrient density.

Downstream Processing:

• Milling & Sieving: Controlled milling achieves uniform particle size (80 mesh standard; customizable for specific applications)

• Metal Detection & X-Ray Inspection: Final product screened for physical contaminants

• Annual Capacity: 100+ metric tons, with flexible production scheduling to match customer demand

3. Stability & Shelf-Life Superiority

• Accelerated Stability Data: Retains ≥90% of initial anthocyanin and polyphenol content after 24 months at 25°C/60% RH (ICH Q1A tested)

• Protection from Degradation: Anthocyanins are sensitive to pH, oxygen, heat, and light. Our nitrogen-flushed, moisture-proof foil packaging (1kg aluminum foil bags, 25kg fiber drums) with desiccant prevents oxidation, moisture absorption, and caking.

• Storage Conditions: Store in cool, dry place (≤25°C, RH <60%), protected from light and moisture

Scientific Evidence: Nutritional Profile & Functional Benefits

Grape powder is a complex food ingredient rich in natural sugars, organic acids, minerals, and polyphenolic compounds. The bioactive profile varies by grape variety and processing method, but consistent benefits have been demonstrated across multiple clinical studies.

1. Cardiovascular Health Support

• Mechanism of Action: Grape polyphenols, including anthocyanins, flavanols, flavonols, and resveratrol, improve plasma lipid profiles, reduce oxidative stress, and modulate inflammatory markers.

• Clinical Outcomes: In a randomized, placebo-controlled study of 44 pre- and postmenopausal women, supplementation with 36 g/day of lyophilized grape powder for 4 weeks resulted in:

  • Plasma triglyceride reduction: 15% in premenopausal women, 6% in postmenopausal women (P < 0.01)

  • Lowered LDL cholesterol and apolipoproteins B and E (P < 0.05)

  • Cholesterol ester transfer protein activity decreased by approximately 15% (P < 0.05)

  • Whole-body oxidative stress (urinary F₂-isoprostanes) significantly reduced

  • Plasma tumor necrosis factor-alpha (TNF-α, a key inflammatory marker) decreased

• Conclusion: Grape polyphenols beneficially affect key risk factors for coronary heart disease through alterations in lipoprotein metabolism, oxidative stress, and inflammatory markers.

2. Antioxidant & Anti-Inflammatory Protection

• Mechanism of Action: Grape polyphenols exert potent antioxidant activity by scavenging free radicals, chelating metal ions, and upregulating endogenous antioxidant enzymes.

• ORAC Value: Our freeze-dried grape powder delivers ≥15,000 μmol TE/100g. For comparison, commercial grape extracts standardized to 80% polyphenols can achieve up to 15,000 ORAC units/g. Grape seed proanthocyanidins (OPCs) demonstrate even higher ORAC values (100,000+ μmol TE/g).

• Clinical Evidence: Beyond the cardiovascular study above, systematic reviews confirm that grape polyphenols positively impact early glycation products, AGEs, and esRAGE, suggesting potential benefits for metabolic health.

3. Metabolic Health & Glycation Support

• Mechanism of Action: Resveratrol and other grape polyphenols trap methylglyoxal (MGO) and downregulate RAGE (receptor for advanced glycation end-products), potentially mitigating glycation-related damage in chronic diseases.

• Clinical Relevance: Grape polyphenols may have a positive impact on early glycation products, AGEs, and esRAGE, supporting metabolic health in aging populations.

4. Cognitive & Neuroprotective Effects

• Mechanism of Action: Whole-grape products, including resveratrol and other polyphenols, have shown considerable promise in protecting against neurodegeneration and aging-associated cognitive decline.

• Research Support: Emerging evidence suggests that grape polyphenols may support cerebrovascular function and regional blood flow in response to cognitive demands, particularly in postmenopausal women and other at-risk populations.

5. Anti-Aging & Cellular Health

• Mechanism of Action: Resveratrol and other grape polyphenols activate sirtuins (SIRT1) and AMPK pathways, mimicking some effects of caloric restriction and promoting cellular longevity.

• Research Support: Whole-grape products have shown promise in maintaining heart health and protecting against aging, aging-associated diseases, neurodegeneration, and some cancers. Resveratrol supplementation has demonstrated anti-inflammatory and anti-oxidant effects in clinical populations.

6. Skin Health & Cosmetic Benefits

• Mechanism of Action: Grape polyphenols, particularly proanthocyanidins from grape seeds and anthocyanins from grape skins, exhibit anti-wrinkle, antioxidant, skin whitening, and photoprotective effects. Grape seed proanthocyanidins improve skin appearance and the look of elasticity, which can reduce the signs of aging.

• Clinical Applications: Encapsulated grape seed extract formulations have been clinically shown to reduce the appearance of wrinkles, brighten skin, and boost hydration, providing multiple benefits even for sensitive skin.
