Why Do Lead Formulators Prefer Our Pea Protein?
If you manage a high-throughput health food facility, an RTD beverage line, or a premium plant-based supplement brand, your primary technical hurdles with vegetable proteins are **grittiness** and the **beany, astringent mouthfeel**.
Xi'an Tihealth addresses this directly at the molecular extraction level. Our isolation system incorporates an advanced, solvent-free **steam-injection flash deodorization protocol**. This targeted physical process strips away volatile aldehydes (hexanal) responsible for the green off-notes, while carefully maintaining the native globular protein structure. The result is a highly soluble, neutral-tasting powder that acts as a flawless, stable canvas for your R&D flavor profiles.
Targeted Applications: Where Does This Isolate Excel?
Naturally rich in Branched-Chain Amino Acids (BCAAs), Arginine, and Lysine, our pea isolate functions as an elite, easily digestible alternative to animal whey. It is the ideal, non-allergenic base for vegan muscle-recovery shakes, meal replacement powders, and high-density functional bars requiring prolonged satiety.
Physical solubility and mouthfeel are critical in liquids. Our wet-milled, enzymatically refined variants achieve an ultra-fine particle distribution that dissolves clearly in seconds. This prevents sedimentation and chalky mouthfeel in fortified plant milks (oat, almond) and vegan yogurts.
Leveraging its exceptional gelation, foaming, and fat-emulsifying properties, food scientists rely on our pea protein isolate to build the authentic fibrous structure and succulent "bite" required in premium plant-based burgers, sausages, and cold cuts.
Extraction Technology: Securing High Yield and Purity
Dry Physical Separation (Centrifugal Fractionation)
For clean-label requirements, we utilize precise centrifugal and airflow classification. This strictly chemical-free, low-temperature route isolates the protein fractions, comfortably securing ≥80% protein on a dry basis while keeping native bioactivity untouched.
Wet Enzymatic Refinement (NSI Optimization)
For liquid applications demanding rapid, stable dispersion, we deploy targeted biocatalysis. This modifies the molecular weight distribution and optimizes the Nitrogen Solubility Index (NSI), drastically enhancing cold-water solubility.

Frequently Asked Questions (FAQ) & Formulation Concerns
Q1: Standard pea proteins carry an intense "beany" off-taste. How does Tihealth eliminate this astringency without using toxic chemical solvents?
The unpleasant beany note is driven by the oxidation of internal lipids, specifically generating volatile aldehydes like hexanal. Traditional chemical de-flavoring often utilizes petroleum-derived solvents which degrade the protein's native structure. Xi'an Tihealth utilizes a physical, high-pressure **steam-injection flash deodorization** protocol. This thermal vacuum stage safely volatilizes and strips away hexanal and related off-notes while preserving the native globular structure, rendering a neutral, flavor-friendly profile.
Q2: Pea proteins are notoriously high in sodium due to sodium hydroxide acid-base sedimentation. How do you achieve a low-sodium profile?
Most commercial pea isolates use sodium hydroxide (NaOH) for alkaline extraction and acid precipitation, leaving massive sodium residues (frequently ≥ 1500mg/100g) which is a major hurdle for low-sodium sports or geriatric formulas. Our facility deploys a **low-sodium ion-exchange membrane filtration system**. By selectively extracting the proteins using a low-cation pH adjustment and washing with demineralized water, we maintain sodium levels strictly **≤ 1000 mg / 100g (typically < 850 mg)** without compromising isolate yield.
Q3: Will the pea protein powder settle or leave a gritty mouthfeel in Ready-to-Drink (RTD) plant milks?
Grittiness is caused by large, insoluble protein aggregates. Tihealth resolves this by processing the isolate through ultra-fine wet-milling and mild enzymatic hydrolysis, achieving an ultra-fine particle distribution (D90 ≤ 10 μm upon liquid dispersion) and a **Nitrogen Solubility Index (NSI) ≥ 85%**. This prevents secondary coagulation and particulate sedimentation, giving RTD beverages, oat milks, and dairy alternatives a silky, premium mouthfeel.
Q4: Is your yellow pea protein powder completely allergen-free and Non-GMO traceable?
Absolutely. Unlike soy or dairy proteins which require strict allergen declarations in global target markets, yellow peas (Pisum sativum) are inherently free from the major global allergens (gluten, lactose, soy, nuts). We strictly source our raw yellow peas from identity-preserved, Non-GMO agricultural cooperative bases. Every single bulk batch is validated via PCR testing and accompanied by a GMO-Free and Allergen-Free declaration to support your regulatory label audits.
