What is the difference between HAS and regular Sichuan pepper powder?

Regular pepper powder contains a complex mix of volatile oils, aromatics, and trace alkylamides. HAS is a purified active responsible for the tingling / numbing sensation — more potent, stable, and controllable, ideal for precise formulation.

Is HAS safe to use in foods and beverages?

When used at appropriate low doses, HAS is generally regarded as safe — especially when sourced from a reputable supplier with COA, purity testing, and proper documentation. Sensory testing and regulatory compliance checks are recommended.

Can HAS be used together with capsaicin or menthol?

Yes — many sensory or multi-sensation applications combine HAS with mild capsaicin, menthol, or other flavor agents. But synergy can intensify the effect, so start with conservative dosages and test carefully.

In what product types does HAS work best?

Beverages (RTD, cocktail), functional drinks, snacks, confectionery, chewing gums, sauces, and certain cosmetics (e.g. lip tingle gloss) are ideal candidates for HAS to deliver novel sensory experiences.

What kind of documentation should a bulk supplier provide for HAS?

At minimum: COA (purity by HPLC), MSDS, heavy-metal and microbial test reports, batch traceability, allergen statement, stability report, and export regulatory compliance support.

Why Hydroxy α Sanshool Is the Game‑Changing Sensory Ingredient for Food, Beverage & Cosmetic Innovation

Introduction

If you’ve ever tasted a dish seasoned with Sichuan peppercorns, you know that distinctive buzzing, tingling, slightly numbing sensation — not quite spicy like chili, but unmistakably vibrant. That sensation comes largely from a compound called Hydroxy‑Alpha Sanshool (HAS). In recent years, HAS has emerged beyond traditional cuisine: it’s becoming a sought‑after ingredient for food & beverage innovators, nutraceutical formulators, and even cosmetic product developers looking to deliver novel sensory experiences.

In this article, we dive into what makes HAS special — the science behind the sensation, its modern applications, safety profile, and why professional buyers are increasingly sourcing it in bulk.

1. The Science Behind the Tingle — How Hydroxy‑Alpha Sanshool Works

Sensory mechanism: Scientific studies have shown that Hydroxy‑Alpha Sanshool activates specific sensory neurons by targeting ion channels in nerve cells. In particular, HAS triggers TRPV1 and TRPA1 channels — the same types involved in responses to spicy, aromatic, and sensory‑active compounds. PubMed+1
Unique nerve‑fiber activation: More detailed neurophysiological research found that HAS excites a subset of mechanoreceptors — including light‑touch D‑hair afferents, as well as Aβ and C‑fiber afferents — creating a distinctive tingling or paresthesia rather than traditional “burning” or “heat.” PubMed
Chemical profile: As confirmed by modern extraction and quantification studies, among several alkylamides in Zanthoxylum species, hydroxy‑α‑sanshool is the predominant compound responsible for pungency and tingling. RSC出版+1

This means HAS isn’t just a flavor — it is a sensory active compound that can modulate nerve response and mouthfeel in a way totally different from capsaicin or menthol.

2. Applications & Industry Use Cases

Because of its unique sensory effect, HAS has a wide and growing set of applications, particularly for professional food, beverage, nutraceutical and cosmetic developers:

Food & Beverage: Use HAS to add a tingling “buzz” to beverages (RTD drinks, functional drinks), confectionery, chewing gums, sauces, and novel snacks. It offers an exotic sensory layer — not spicy hot, but vibrantly tingling.
Functional Foods & Nutraceuticals: As consumer interest grows for sensory‑driven products, HAS can add unique mouthfeel or sensory activation to wellness formulations (e.g. mood‑boosting gummies or chewables).
Cosmetics & Personal Care: HAS’s sensory activation isn’t limited to the mouth — topical formulations (e.g. tingling lip plumpers, lip balms, or skin‑feel enhancers) can leverage its nerve‑stimulating properties for a novel user experience. Indeed, experimental use of sanshool-like compounds in “chemical haptics” (skin/tactile feedback) is being explored in academic research. lab.plopes.org
R&D / Sensory Science / Neuro‑Science: Because HAS reliably and selectively activates mechanoreceptors / sensory neurons, labs studying somatosensory response, oral perception, or neural modulation can use it as a tool for research.

Moreover, new research has suggested biological benefits beyond sensation. For instance, a recent animal / cell‑based study reported that Hydroxy‑α‑sanshool may promote browning of white adipose tissue (WAT), potentially impacting energy expenditure and fat‑metabolism via TRPV1‑mediated pathways.

3. Safety Profile & Regulatory Considerations

Traditional use & safety: The active compounds in Zanthoxylum (including HAS) have been consumed for centuries in cuisines. Many regulatory assessments consider Sichuan peppercorn-derived ingredients safe in typical culinary amounts. spice.alibaba.com+1
Caution on potency: Because pure HAS is more concentrated than whole peppercorns, formulations should carefully consider dosage. Excessive use could lead to prolonged or intense tingling, which may be unpleasant for consumers.
Quality matters: As with all botanical extracts, purity, extraction method, and consistent batch quality are essential. Reliable suppliers should provide COA, MSDS, HPLC profile, heavy‑metal & microbial tests, and follow GMP or HACCP standards.

For professional buyers, sourcing from a regulated, quality‑focused manufacturer (like our factory) ensures safety, traceability, and regulatory compliance.

5. Common Questions (FAQ)

Q1: What exactly is Hydroxy‑Alpha Sanshool (HAS)?
A: HAS is a bioactive alkylamide found naturally in Zanthoxylum species (e.g. Sichuan pepper). It is responsible for the characteristic tingling / numbing sensation those peppers create — quite different from the heat of chili peppers.

Q2: Is HAS safe for use in food, beverage, or cosmetic products?
A: Yes — in culinary or moderate use. Traditional use and scientific literature support its safety when used at appropriate levels. For concentrated extracts or novel applications, always ensure proper purity, dosing, and regulatory compliance.

Q3: How is the “tingling” sensation generated?
A: HAS activates specific sensory neurons by interacting with ion channels (notably TRPV1 and TRPA1) in the peripheral nervous system, triggering sensations of tingling, buzzing, or mild numbing. PubMed+2PMC+2

Q4: What industries can benefit most from HAS?
A: Food & beverage (especially novel or functional drinks/snacks), nutraceuticals, confectionery/gum makers, cosmetic/personal care formulators, and sensory‑science research labs.

Q5: What should buyers look for when sourcing HAS?
A: Look for documented COA, purity by HPLC, microbial/heavy metal testing, consistent batch-to-batch quality, stable supply capacity, and compliance with international standards (e.g. GMP, HACCP).

Q6: Can HAS deliver functional health benefits (beyond sensation)?
A: Early preclinical research suggests possible metabolic effects — for example, promoting browning of white fat via TRPV1/AMPK pathways in adipose tissue. PubMed However, human clinical data remain limited; any functional or health claims must be carefully substantiated.
