MaxxLive ethanol emitter — extend bakery shelf life, prevent microbial growth

MaxxLive ethanol emitter sachets — keep bakery fresh for far longer!

An ethanol emitter is an Active Packaging innovation — shelf-life extension packaging developed specifically for high-moisture bakery and baked goods, to prevent microbial growth while preserving texture, softness and the quality of bread and cake.

This article introduces MaxxLive, the first ethanol emitter in Thailand officially approved by the Food and Drug Administration (FDA) for use in food packaging, to extend shelf life and maintain product quality effectively and safely. Its international quality standards have kept it the market leader in sales for more than 15 years, trusted by the bakery industry across Thailand.

How does the MaxxLive ethanol emitter extend the life of baked goods?

MaxxLive is an ethanol-releasing sachet. Placed inside a tightly sealed food package, it releases food-grade ethanol vapour at a controlled, steady rate into the package headspace, effectively extending shelf life and preserving product quality.

• Inhibits microorganisms: the released ethanol suppresses the growth of spoilage organisms — bacteria, yeasts and moulds — extending product life.
• Food science research shows that ethanol emitters significantly inhibit microorganisms and extend the life of bread. Latou et al. (2010) found that using an ethanol sachet extended the life of sliced wheat bread by at least 4 times. Janjarasskul et al. (2016) found that applying the MaxxLive ethanol emitter together with the BestKept oxygen absorber extended the life of Trang cake (sponge cake) by at least 14 times.
• Preserves texture: ethanol keeps products soft by inhibiting staling — the chemical and physical process in bakery products such as bread and cake, caused by starch retrogradation and water migration from the crumb to the crust and then out into the environment, which leaves products hard or dry over time. An ethanol emitter therefore keeps texture soft for longer.
• Sheng et al. (2015) reported that an ethanol sachet significantly preserved the texture of Chinese steamed bread, consistent with Janjarasskul et al. (2016), who found that Trang cake packed with the MaxxLive ethanol emitter had clearly lower hardness (a texture attribute reflecting cake firmness) than samples packed without one — clear evidence that an ethanol emitter preserves softness.

MaxxLive ethanol emitter — a new and safe approach to food preservation

MaxxLive is manufactured under FDA licence using highly pure, food-grade ethanol with a strong safety profile:

• Ethanol is a naturally occurring antimicrobial: it is a compound formed by natural processes (yeast fermentation) and is generally regarded as safe, holding GRAS (Generally Recognized as Safe) regulatory status under United States food law.
• Ethanol evaporates quickly and leaves no residue: when the consumer opens the package, ethanol vapour dissipates rapidly because alcohol has a low boiling point — leaving no unwanted residue and little foreign taste or aroma in the food, when used at an appropriate size and quantity.
• Ethanol breaks down through natural mechanisms.
• The human body metabolises ethanol: the alcohol remaining in products preserved with MaxxLive is very low (below 1%) and therefore safe, as ethanol is rapidly metabolised into water and carbon dioxide through a natural process, leaving no toxins or residues accumulating in the body.
• Residual alcohol is comparable to everyday foods: the ethanol remaining in the product is at the same level found in food we eat daily — bread and baked goods made with yeast (below 1%), soy sauce or fermented soybean paste (1-3%), and yoghurt (0.1-2%). These come from natural yeast fermentation, as part of processing or of preservation itself.

Choosing the MaxxLive ethanol emitter to extend bakery shelf life is therefore a safe new option that stops mould problems and protects consumers from microbial hazards effectively — without them having to consume preservatives directly.

MaxxLive Ethanol Emitter — a superior bakery preservation innovation

Extending bakery shelf life with alcohol is not new; it is a leap forward from traditional practice. The MaxxLive Ethanol Emitter was developed from the traditional technique of keeping bakery products such as fruit cake and rum cake for long periods, which historically meant sprinkling or brushing alcohol on after baking to inhibit mould growth and add moistness to the crumb.

Spraying alcohol, however, only sanitises temporarily: it soaks into the product immediately and is confined to the area sprayed. It generally has to be reapplied periodically as a form of "feeding", depending on how long the product must keep. Most importantly, spraying risks damaging the bakery product — excess moisture, blotches, or residual alcohol odour — which directly affects the taste and appearance of the product.

The MaxxLive ethanol emitter, an Active Packaging shelf-life innovation, applies this principle of slowing microbial growth with alcohol in a far more effective and controllable way. It works by creating an ethanol vapour atmosphere inside the package that inhibits microbial growth, through slow and steady controlled release — suppressing spoilage organisms thoroughly, both on the food surface and in the air surrounding the product inside the package.

MaxxLive is therefore an anti-mould packaging innovation that is effective, stable and long-lasting, with no adverse effect on product quality — a smarter new option for extending the shelf life of bakery and other high-moisture confectionery.

How do you use the MaxxLive ethanol emitter?

Using MaxxLive is simple and convenient. For maximum preservation and safety, follow these steps:

• Prepare the packaging
• Airtight packaging: MaxxLive must be used with packaging that can be hermetically sealed — for example plastic bags closed by heat sealing, plastic cans sealed with a double-seam lid, or easy-peel lids closed by weld sealing — so that the ethanol vapour is retained inside and can work effectively.
• Calculate the sachet size: choose the right MaxxLive size, calculated from the product weight and the water activity (aw) of the food. Contact us to send samples for aw testing and MaxxLive size calculation.
• Placing the MaxxLive sachet
• Pack it with the product: once the bakery product (bread, cake, mochi, pie and so on) is in the package, immediately place the MaxxLive sachet — still unopened — inside.
• Sealing
• Seal immediately: after placing the MaxxLive sachet, seal the package tightly straight away.
• It starts working: once the package is sealed, the ethanol sachet releases alcohol vapour at a controlled rate, inhibiting microorganisms effectively and continuously.
• Storage
• Store normally: products can be kept at room temperature (for example 1-6 months, depending on the product). Where a much longer extended shelf life is needed (more than 6 months) — for export products travelling long distances, for instance — the effect of ethanol can be combined with cold storage (refrigeration) to extend shelf life further, using two preservation principles working together in synergy (dual defence).

Additional advice: to reinforce the shelf-life performance of Active Packaging, start with a good-quality product with a low initial microbial load. See our tips on storing food in the refrigerator to extend freshness and reduce loss, and on FIFO and FEFO stock rotation for lowering the initial microbial load.

Which foods can the MaxxLive ethanol emitter be used for?

Ethanol emitters preserve high-moisture foods that spoil easily from microbial growth and have a short shelf life, including:

• 1. Breads — basic breads: white bread, whole grain/multigrain bread, sourdough; specialty breads: layered bread, shio pan (salt bread), Hokkaido milk bread, shokupan (Japanese milk bread); high-fat baked goods: brioche, croissant; other formats: rolls, filled breads and buns.
• 2. Cakes and pastries — cakes: high-fat types such as butter cake; sponge types such as sponge cake, chiffon cake, roll cake/Swiss roll. Traditional Japanese confectionery (wagashi) containing sweet red bean paste or flour, such as daifuku, mochi, manju, or dorayaki (Japanese pancake with red bean filling). Other items such as waffles and pancakes.
• 3. Thai desserts, souvenir sweets and auspicious sweets — such as foi thong, thong yip, thong yod, salee cake, pui fai cake, khanom thuay fu, alua, foi thong cake, Chinese pastry, and grilled dice cakes.

Additional advice: for confectionery or bakery products classified as dry foods (water activity, aw < 0.6) — such as crisp cookies, crackers, crisp biscuits, crisp meringue or crisp foi thong — the priority is preserving crispness, because these products already have water activity too low for microorganisms to grow. A desiccant sachet is the most suitable choice, to absorb any moisture entering the package and prevent the loss of the product's characteristic texture. See our further tips on storing dry foods.
