Then I Looked Up the Xanthan Gum. - URL: https://www.organicfoodtogether.nz/i-bought-a-hot-sauce-because-it-said-organic-then-i-looked-up-the-xanthan-gum/ - Published: 2026-09-28T17:31:43.000Z - Updated: 2026-09-28T17:31:43.000Z - Description: I bought a Nelson hot sauce because it said organic and 100% natural. Then I looked up the thickener on the label: where xanthan gum came from, how it's made, and what it does in your gut. - Author: Luke Nicholas - Tags: xanthan gum, Nelson, hot sauce, chilli, food additives, organic certification, food labelling, I bought a bottle of Te Chili hot sauce from Commonsense Mt Eden because the label said organic and 100% natural. That's the whole reason. I like chilli, I trust what's on Commonsense's shelves, and those two words did their job on me exactly the way they're meant to. Then I did what I always do afterward. I looked closer. ## What the label actually promises Te Chili is made by Patrick Gilgenberg, a Nelson chef who ferments chillies grown at Ruby Bay and bottles the result out of Pic's Food Factory in Stoke (per [Uniquely Nelson's 2023 profile](https://uniquelynelson.nz/2023/08/15/techili-some-like-it-hot-organic-chilli-sauce-made-in-sunny-nelson/?ref=organicfoodtogether.nz) and [Te Chili's own site](https://www.techili.co.nz/?ref=organicfoodtogether.nz)). The range comes in three labels, and the organic claim isn't worded the same way twice. The Habanero bottle carries "ORGANIC" as its own banner headline, the same visual weight you'd expect from an actual certification mark. The Chipotle bottle instead says "New Zealand chillies grown organically and crafted to perfection since 2022" as a sentence rather than a standalone word. The Double Hot Sauce bottle says "grown organically & crafted to \[100%\] natural." Three variants, three different strengths of the same underlying claim. Te Chili is also a product with real reach. It's sold through organic and wholefood retailers from Auckland to Queenstown: Commonsense's Auckland and Wellington-region stores, The Urban Market, Pic's Peanut Butter World and several other Nelson/Tasman shops, Piko Wholefoods and two FreshChoice stores in Canterbury, and Royalburn Farm Shop near Queenstown, among others. This isn't a one-shop curiosity, it's a small producer with genuine national distribution through the country's organic retail network. ## What's actually on the label I've now got a clear photo of all three ingredient panels: - **Chipotle:** water, chillies (35%), vinegar, salt, chipotle (imported), thickener (xanthan gum) - **Habanero:** water, chillies (35%), vinegar, salt, thickener (xanthan gum) - **Double Hot Sauce:** water, chillies (35%), vinegar, salt, thickener (xanthan gum) By hot sauce standards, that's a short list. No preservatives in the additive sense, no added sugar, no stack of gums and stabilisers. Salt and vinegar are traditional preservation, not industrial ones. But "100% Natural" sits awkwardly next to xanthan gum, listed on the label itself as "thickener," an ingredient that doesn't occur in a jar of fermenting chillies on its own; it's manufactured separately and added afterward, for texture and stability the fermentation and 35% chilli apparently don't reliably deliver by themselves. The Chipotle variant adds a wrinkle the other two don't have. Chipotle is smoked, dried jalapeño, a separate manufactured ingredient in its own right, and the label states it's imported, with no origin or organic status given. That bottle still carries the "grown organically" claim, which technically refers to the fresh New Zealand-grown chilli component, but it sits next to an imported ingredient of unstated provenance in the same short list. Worth being precise here too: xanthan gum isn't a preservative, so it doesn't contradict any "doesn't require preservatives" claim. The claim it actually strains is narrower: "100% Natural" and "minimal ingredients that let the chillies speak for themselves." On every variant, one of five or six ingredients is neither a chilli, a fermentation product, nor a traditional preservative. ## What's actually behind "organic" New Zealand has five organic certifiers, according to [Organics Aotearoa New Zealand](https://www.oanz.org/organic-certification?ref=organicfoodtogether.nz): AsureQuality, BioGro, a biodynamic scheme (Demeter), an indigenous verification system, and OrganicFarmNZ, which offers lower-cost certification for smaller producers who sell only in New Zealand. I've checked the three that publish searchable lists. [BioGro's certified operator directory](https://biogro.co.nz/licenseeprofiles?ref=organicfoodtogether.nz), searched under "chilli," returned nine results: certified chilli, chilli pepper and chilli sauce producers and licensees around the country, from small growers to a plant-based sausage maker using organic garlic and chilli. Te Chili, Patrick Gilgenberg, and Ruby Bay don't appear anywhere in that list. AsureQuality's certified operators and products register, searched across every sheet (processors and handlers, primary producers, input manufacturers) for "Gilgenberg," "Te Chili," "Techili" and "Ruby Bay," returned nothing for the business at all. The only Ruby Bay match in the entire register is an unrelated apiary business certifying honey, wax and other bee products. OrganicFarmNZ, the small-grower scheme, publishes a [certificate checker](https://www.organicfarm.org.nz/certificate-checker?ref=organicfoodtogether.nz) listing its current certificate holders. Te Chili isn't there either. So Te Chili isn't listed with BioGro, AsureQuality or OrganicFarmNZ. I didn't find public lists for the other two certifiers, Demeter and the indigenous verification scheme, and an overseas certifier could only matter for the imported chipotle. What the three searches do show is that the "organically grown" printed on these labels isn't backed by a certificate number in any of the registers I could search. You can run the same check on any product: all three publish searchable lists. ## What xanthan gum actually is Given how much work this one ingredient is doing in the story, it's worth knowing what it actually is, rather than just that it's "not chilli." **Where it came from.** Xanthan gum came out of the US Department of Agriculture's research lab in Peoria, Illinois, where chemist Allene Rosalind Jeanes worked from 1941 to 1976\. Jeanes had already helped develop dextran, a blood volume expander the US Army used in the Korean War, and she is credited with developing xanthan gum as well ([USDA Agricultural Research Service](https://www.ars.usda.gov/news-events/news/research-news/2017/national-inventors-hall-of-fame-honors-ars-scientist/?ref=organicfoodtogether.nz)). The bacterium that makes it, Xanthomonas campestris, causes black rot on vegetables such as broccoli, and the gum found its way into processed foods as a thickener in the 1960s ([NPR](https://www.npr.org/sections/health-shots/2011/05/23/136574547/fda-warns-against-food-thickener-for-premature-infants?ref=organicfoodtogether.nz)). The FDA approved it as a food additive in 1968 ([USDA Agricultural Research Service](https://www.ars.usda.gov/news-events/news/research-news/2017/national-inventors-hall-of-fame-honors-ars-scientist/?ref=organicfoodtogether.nz)). Its additive code in Europe is E 415. **How it's made.** It's a polysaccharide, a large sugar molecule, that the bacterium produces when it's grown in fermentation vats, and it's then dried and milled into the powder sold as an ingredient. **Why it's used at all.** The Nature Microbiology paper on xanthan gum describes it as a stabiliser and thickener with unusual rheological properties, which means it changes how a liquid flows. Michigan Medicine's write-up of the same study puts it more simply: it's added to processed foods, from yoghurt to baked goods to salad dressing, because it makes liquids much more viscous. The USDA lists toothpaste, egg substitutes, ice cream and some gluten-free foods among the products that use it. **What it does in your gut.** This is the genuinely interesting, still-open part. A [2022 study in Nature Microbiology](https://www.nature.com/articles/s41564-022-01093-0?ref=organicfoodtogether.nz), led by researchers at the University of Michigan and the Norwegian University of Life Sciences, found that the ability to digest xanthan gum is common in the gut microbiomes of people from industrialised countries, and that it appears to depend on a single bacterium from the family Ruminococcaceae that hasn't been grown in a lab. A second gut bacterium, Bacteroides intestinalis, can feed on the fragments the first one releases. When the researchers fed xanthan gum to germ-free mice carrying a human gut microbiome, it drove growth of both bacteria. The genetic signatures for digesting xanthan gum were relatively absent in samples from people in non-industrialised countries, according to [Michigan Medicine's summary of the study](https://www.michiganmedicine.org/health-lab/study-helps-explain-how-xanthan-gum-common-food-additive-processed-gut?ref=organicfoodtogether.nz). The same write-up notes that mice could also process it, which may mean some of that ability was already present in the mammalian gut. The lead author said xanthan gum is generally considered safe, but the results suggest that widespread consumption may be enriching our microbiomes for bacteria that eat it. He called the study a first step in working out whether changes like that are good or bad, and pointed to people with celiac disease and those on gluten-free diets, who tend to eat more of it. Nobody has shown the change is harmful, and nobody has shown it's fine. One disclosure worth knowing: the paper's competing-interests statement lists several of its authors on a patent application covering enzymes that process xanthan gum. The one serious harm case on record involved a very different use. SimplyThick, a thickening gel with xanthan gum as its active ingredient, was added to breast milk or formula for premature babies who had trouble swallowing. By May 2011 the FDA knew of 15 cases of necrotizing enterocolitis, a serious bowel condition, in babies fed it, including two deaths, and it warned against using the product for premature infants ([NPR](https://www.npr.org/sections/health-shots/2011/05/23/136574547/fda-warns-against-food-thickener-for-premature-infants?ref=organicfoodtogether.nz)). A later review by FDA staff counted 22 cases, 21 of them premature babies. The authors were careful to say that a case series can't prove the product caused the illness, though they proposed it may raise the risk in that group ([abstract of the FDA authors' paper](https://www.sciencedirect.com/science/article/abs/pii/S0022347612003630?ref=organicfoodtogether.nz)). That's a thickening gel fed to newborns with immature guts, a different exposure from a splash of hot sauce in an adult diet. ## The claim I still can't fully settle Te Chili also markets itself as probiotic. Here I've now got more to go on than I did. Every bottle carries the instruction "Refrigerate after opening," printed right on the label, next to a best-before date roughly a year out while sealed. That's consistent with a genuinely unpasteurised, live product: shelf-stable and sealed thanks to acidity and salt, but needing the cold once opened to protect whatever live activity remains. It doesn't prove a meaningful bacterial count survives to the point you eat it, but it's a real, specific, printed instruction rather than an empty marketing word, and it points toward "probiotic" being plausible rather than hollow. ## Where that leaves it "Organic" is a word you can check, so I checked it. BioGro's directory, AsureQuality's register and OrganicFarmNZ's certificate checker all come back empty for Te Chili. The shelf tag under the Habanero at Commonsense says "contains organic ingredients", which is a more careful claim than the one printed on the bottle. The sauce is still good and the ingredient list is short. The label just says more than anyone can verify. --- **Before you go:** if you want more of this, [sign up here](https://www.organicfoodtogether.nz/#/portal/signup), it's free.
