Moving Away from MSG: What Food Manufacturers Need to Know About Sodium Reduction

Sodium reduction projects usually start with a regulatory deadline and end with a taste problem. The gap between those two things is where formulation teams actually earn their keep.

The deadline pressure is real. All 194 WHO Member States committed to cutting population sodium intake by 30% by 2030, a target the WHO’s own 2023 Global Report confirmed no country is currently on track to achieve. Rather than softening expectations, that gap has pushed governments to act independently. Canada made front-of-pack sodium labelling mandatory in January 2026. Indonesia now flags high-salt products on pack through a traffic-light system. The EU’s updated Nutri-Score algorithm penalises sodium-heavy products more harshly than before. The timelines differ by market. The direction is the same.

MSG pressure works differently and it’s commercial, not regulatory. Retailers, QSR chains, and private label brands increasingly write MSG-free into supplier specs as a default, driven by consumer expectation rather than any legal requirement. For food technologists, both things arrive as the same problem: how do you cut sodium and remove MSG without the product tasting like something is missing?

Why Sodium Reduction Keeps Failing

Salt does more than add saltiness. It suppresses bitterness, rounds out harsh notes, and contributes to mouthfeel in ways that only become obvious once it’s gone. Pull sodium chloride without putting something back, and the result is usually flat, bitter, or strangely thin. Consumers pick it up even when the percentage cut looks small on paper.

This is where most reformulation projects run into trouble. Not in the reducing, but in the replacing.

What HVP and Yeast Extract Do in Practice

HVP is made by hydrolyzing plant proteins like soy, wheat, groundnut into their constituent amino acids. The product is rich in glutamic acid, the same compound responsible for MSG’s savoury effect. Because those glutamates come from protein breakdown rather than direct addition, HVP carries a natural flavour enhancer declaration rather than monosodium glutamate. For manufacturers working to an MSG-free spec, that difference shows up on the label.

Yeast extract works on a slightly different basis. A 2026 peer-reviewed study on beef burger formulations found that pairing micronised salt with 2% yeast extract at 50% sodium reduction produced taste panel scores comparable to full-sodium controls, with the formulation rated “just right in saltiness”. The mechanism involves yeast extract compounds interacting with sodium ion channels in taste receptor cells  and amplifying how salt is perceived rather than how much is present.

HVP is increasingly the go-to ingredient in low-sodium formulation briefs. Future Market Insights values the global HVP market at USD 1.8 billion, with growth driven largely by its application in reduced-sodium soups, sauces, seasonings, and convenience foods.

One detail that doesn’t always come up in procurement: acid-hydrolysed HVP produces 3-MCPD, a contaminant that both the EU and CODEX Alimentarius regulate. CleanSavour™ HVP from Herbal Isolates uses enzymatic hydrolysis, which produces substantially lower 3-MCPD levels and meets EU and CODEX thresholds that are relevant for any manufacturer supplying European retail or buyers with stringent audit requirements.

Building a Formulation That Holds

Single-ingredient substitution rarely delivers acceptable results. What tends to work: yeast extract to recover umami and lift saltiness perception, HVP to add savoury body, and seasoning adjustments to handle the bitterness that surfaces as sodium levels fall. In soups and bouillons, that combination routinely supports 25–35% sodium reduction within sensory thresholds. Sauces and condiments typically land at 20–30%, depending on the base.

Dosing sequence and ingredient interactions both affect the outcome, and there’s no standard formula that works across applications. Herbal Isolates’ technical team works with manufacturers through application-specific trials,  not just as a supplier, but as a formulation partner.

Herbal Isolates manufactures HVP and CleanSavour™ HVP at BRC AA-certified facilities in India. Manufacturers who’ve been rethinking their HVP supply,  particularly those moving away from Chinese-origin material over 3-MCPD compliance concerns or supply concentration risk have found it a workable alternative.
