Food safety when keeping chocolate or compound melted


Posted in: Chocolate Education

Loads of documentation out there on the role of water activity and food safety - do a google search for water activity chart, for example, and you'll get a handy printable wallet card you can give your friendly food inspector. water activity (Aw) isn't a measure of how much water is present - it's a measure of how much water is *available*. For chocolate/compounds, they're essentially the same thing. Your typical coating will have an Aw of approx 0.2-0.3 - which is 2-3x lower than is required to support the most basic forms of microbioogical growth (the minimum Aw required to support growth is slightly above 0.6 Aw)

If you're talking something like milk, sauces, soups, etc - things that are mostly water - 100F is where mesophilic bacteria love to play - likely your food inspector is looking at it through the lens of the buffet line at your local old country buffet - where if you leave almost anything there at 100F for very long, you're likely to get very sick. since there's only tenth's of a percent of water in compound, and any of the water that's there isn't available to support growth anyway (ie it's either in the form of water of crystallization, surface monolayers adsorbed to milk/sugars, etc), there's absolutely zero risk of micro growth. as long as you're not adding anything with moisture into it. Your supplier can give you the exact Aw, moisture content, and ingredient label that you can then give to your inspector to prove there's no risk.

EDITED to note that frequently washing your chocolate melters can actually INCREASE the risk of microbiological contamination. if seems many cases where post washing, equipment has not been dried properly - and that'll lead to problems. certainly not saying you shouldn't be washing your equipment, but many folks overwash or wash improperly and unintentionally increase their risk exposure. Large scale enrobers NEVER get water washed. Water is quite often the enemy in a chocolate plant.

Cacao Powder Grinding


Posted in: Tasting Notes

I'm afraid there is no such thing as a cold pressed cocoa powder - at least i've never seen one. it may be an expeller process, but it's still going to be a hot process. The purpose of pressing is to get the cocoa butter out, and if the cocoa butter is solid, it won't come out. If you use a supercritical solvent extraction process, you can keep the temperature down, but it wont be organic then.

Really the only benefit of keeping the temp low might be to keep some of the heart healthy components around longer - which are bitter.

Sounds like whomever is making it isn't giving you quite the right process description, and from what you're indicating, however they're grinding it is simply insufficient. there's plenty of cocoa processors in your neck of the woods who will be capapble of doing a typical grind cocoa powder. i think i might know the answer - but out of curiosity who's supplying your current powder?

I think you'd need to determine what it is you need, why you need it - and then determine how to get there. my guess is there's quite a bit of cocoa out there already that suits your needs... but then again you may have very unique needs!

Cacao Powder Grinding


Posted in: Tasting Notes

Most cocoa powder is 8-10 um in particle size - if you require finer, try something like a jet mill.

I'd be surprised if you required finer than that. It's probably easier simply to find an alternate cocoa powder - perhaps the one you're using is of poor quality. Jet milling can give you sub micron particle size, but it will be very, very expensive.

Deoderized or natural?


Posted in: Tasting Notes

Deodorized should have less color and less residual flavor than natural (should - if they're deodorizing correctly...). Which should you use? depends on if you'd like that extra flavor/color in your product or not. color won't matter for your dark or milk - it may for your white. flavor always matters. depends on what type of flavor you're after.

Sugar Free


Posted in: Opinion

I could certainly walk through my degrees and where they came from, but i suspect that's not really where your question lies. I understand you *want* to believe that something's that effectively almost pure NaCl with a few minor minerals in it will be a healthful panacea - however it's very well understood that in order to get that little bit of minerals, you end up getting a lot of salt - which is also similarly understood to be a direct driver of hypertension. See The Lancet, Harvard medical student review, or any one of the 10,000 other reputable sources that have published as much. I could also review a list of the peer reviewed journals i've published in, and the clinical trials that have been conducted. My work has, over the years, helped shape current FDA (for the US) policy and similar agencies in other countries all over the world. You are correct that i'm not employed by 'the big boys club' of the FDA. Lecithin does absolutely nothing to 'balance the acid and alkali' in chocolate. It's function is purely as an ampiphillic emulsifier.

If you are marketing a food product as a medicinal food, or as appropriate for a demographic that has serious health issues - it comes with a responsibility to do so in a fashion that is consistent with current medical understanding. Marketing salt (and lets be honest here - Himalayan salt IS salt) as heart healthy because it has a few minor minerals (and again - lets be honest - they are VERY minor - the average NaCl composition of this salt is 95%..). It's irresponsible. Likely illegal (you ARE familiar with the US labeling requirements related to sodium content and heart health, correct?)

I've been at this a very long time. It's been my observation that there's a group of folks who desperately want to believe in non-traditional approaches (raw food, high salt, low carb, whatever), and often outright discredit mainstream science, while quoting the non-traditional sources or personal experiences that have not been peer reviewed, published, or even replicated. There almost always is no reputable science that has been replicated backing any of it up. What i find interesting is when those folks comes to an established board asking for information, and when they do not receive the answer they like, proceed to disparage and attempt to discredit the one who attempted to help them, because the answer did not lie within the constraints of their pre-existing personal belief system.

I will not engage in an extended discussion on this past this post.

Ah, the power of marketing.

Adding salt is not a great way to make something heart healthy.

Chocolate liquor has about 1% natural sugars in it.

The FDA doesn't have time to visit most large food mfrs, much less the small mom & pop shoppes.

Posted in: Opinion

Then it's basically just liquor. As Clay notes, it's not going to be a chocolate bar as most people have come to expect.

Nutritional values can either be generated using what's called the 'red book' of food nutritive values (basically a generic template of food categories maintained by the FDA), or using compositional analytical data generated in house or by your supplier. Almost everyone uses the red book, because it's easier.

need help with a long shelf life idea... Chocolate and oil ' meltaway ' centres .


Posted in: Recipes

I think the answers depend greatly on the details. I've had folks absolutely swear by tempering of the chocolate before mixing it with an oil. Personally, in every objective test i've ever done, i can't find evidence that's of long term textural benefit. Once you add a low saturated oil the mix, it blows up any benefits of tempering. I know this will be hotly contested, and folks - do whatever you think gives you the best results. Personally i'd save the time.

As to the ratio - again, depends on the specifics of your chocolate, it's formulation, and what oil you're planning on using. You might consider using something like a fractionated palm kernel oil for stability's sake (no one wants a rancid truffle), or you might opt for something like a canola oil with some vitamin e (antioxidant) - although truth be told i've not tested that variable, and while it makes sense that it'd work, i can not say with certainty.

If she's happy with the texture of the lindor truffle, it's not very difficult to determine how lindt's getting that by simply looking at their label 8-) while i've not had your ganache truffles (feel free to fix that by sending some to....), i think you'll be quite hard pressed to get an oil based truffle to match that of your cream based one, so be sure to manage expectations that the lindor's the target

If you have pure cocoa butter you can't add too much unless it becomes cost prohibitive, or flavor prohibitive. Keep adding until cost or flavor no longer works. Additionally, you can try adding 0.1% fluid soy lecithin.

Dry Seed Cleaner Adapted to Cacau


Posted in: Tasting Notes

Some countries are exporting with 25% trash. Do this long enough, and you'll find everything you can imagine (and things you wouldn't have imagined) in cocoa beans.

Long term planning and critical thinking are not strong in all parts of the world - especially when you may not know where you're going to get the money to buy dinner tonight. As a result, short term financial decisions are often made - such as "if i put rocks in this bag, it weighs more and i'll get more money today". In actuality, while this is true for today, what it means is that they're shooting themselves in the foot for tomorrow - as folks will catch on to the fact that they're not buying what they think they're buying. That said, if i don't eat today, i don't care much about tomorrow.

A fundamental shift across multiple origins around incenting quality at the grower AND exporter level is needed to change the mindset. It's incredibly difficult, and I don't believe it'll occur on a large scale quickly.

Not roasting will eventually lead to you either making someone very sick, or killing them. The topic has been been discussed quite thoroughly here and on the alchemy board.

I simply can not figure out where this notion of not roasting = healthier comes from, and why it's so persistent.

Production of chocolate


Posted in: Tech Help, Tips, Tricks, & Techniques

afraid you still don't have nearly enough information. you list your ingredients, but it's not the formula. The details are incredibly important (ie what fat milk powder? what size media, temp of your mill, and # of passes (i assume you have multiple passes?) what's the temperature increase over multiple passes?)

What do you need to do - you need to provide a great deal more information, i'm afraid.

Moisture is always a problem....

well, you're going to need to provide many more details if you'd like help. Specifically:

1) Exact formula of your chocolate, including details on the milk ingredients used

2) timing of addition of ingredients

3) how you operate your ball mill.

I will tell you, that using a ball mill for white chocolate isn't the best solution.

Shelf life of Pernigotti cocoa powder


Posted in: Chocolate Education

A very small amount of cocoa powder will have been processed to contain lecithin. Unless you've specifically asked for it, yours is not.

Why do you read that? i've no idea 8) i've read lots of crazy things on the internet.

One t hing you'll need to watch with higher fat powders is that they will be more susceptible to both temperature and pressure, in that the fat in them may melt or squeeze out, and when it resolidifies, will turn yoru bag of nice powder into a brick of solid cocoa. however, it's still fine, it's just needs to be reground.

What the Chocolate Industry Needs is A $100 Bar of Chocolate


Posted in: Opinion

It was tongue in cheek. however i suppose i could do bars based off of extra-ordinarily rare trees (most people don't have access to germplasm databases), or crossed with things like theobroma grandiflorum.

However, uniqueness of raw materials and skill/knowledge of the preparer aren't going to be sufficient to justify/sustain an elevated price. There will need to be something less directly product related to accompany it.

Nut allergies and cross contamination of machines


Posted in: Tech Help, Tips, Tricks, & Techniques

Given the legislation and severity of getting it wrong (from the standpoint of impact to potential consumers), i'd go with the most overt labeling route possible. I'd also suggest you have the discussion with your FDA inspector to ensure you're up to speed with the latest information.

FYI, there's a great deal of talk at the FDA around elimination of the 'may contain' type statements - the argument being that either a product does contain something, or it doesn't.

effect of lecithin on viscosity and its affinity for sugar i.e how it reacts with sugar?


Posted in: Tasting Notes

Lecithin is an emulsifier - that is, it provides 'slipperiness' between the fat in your chocolate, and the water - for as you know, the two don't mix well. Yes, there is water in your chocolate - a little bit comes with the sugar, the milk, and the cocoa components for example, or the relative humidity in the production area. Lecithin is an ampi-phillic molecule - ie one end 'likes' to stick to lipids (fats), and one end likes to stick to hydrophillic things (such as water).

Lecithin is a mixture of lots of things, but the 'active' element of lecithin can vary. The viscosity reducing capability of lecithin depends on many, many, many things, one of which is how much of the active component is present. Total moisture content, total fat content, particle size, particle distribution, conch time, etc all factor in as well.

To your main question, lecithin is thought to 'coat' the particles of sugar, with it's hydrophillic end touching the sugar, and it's lipophillic end pointing outwards towards the cocoa butter. This provides a 'bridge' between the two, allowing for them to slip past one another, instead of forming a sticky mess.

Posted in: Tech Help, Tips, Tricks, & Techniques

Not sure of your question - you seem to be asking two unrelated things...

1) nutritional calculator

2) UPC bar code printer

Is it that you're looking for a single program that does both? There is no requirement to bar code anything for nutritional information.

A number of years ago, i was unhappy with the commercially available recipe, spec, and nutritional programs - so i built my own. I've no idea what goes into bar coding, but my guess is with a little elbow grease you could figure it out - perhaps building your own is the way to go if you're not finding what you want?
