<strong>Caramel</strong> — <strong>Raw</strong> <strong>Materials</strong> <strong>and</strong> <strong>Formulations</strong><br />

So many things<br />

about the milk can<br />

have an effect. The<br />

differences in the<br />

raw milk itself, how<br />

it was processed,<br />

stored <strong>and</strong><br />

reconstituted, all<br />

have their effect,<br />

mostly due to<br />

protein quality.<br />

the sugar, fat, lactose, total protein <strong>and</strong><br />

water levels.The numbers again are examples<br />

(Figure 4).<br />

Look at the sugar in the scwm, it’s<br />

almost a quarter of all the sucrose in the<br />

caramel recipe <strong>and</strong> most of the solids of the<br />

ingredient. Remember to check with your<br />

supplier for exact numbers.<br />

There are many other forms of milk that<br />

can be used or even different components<br />

from milk such as just adding casein or<br />

whey.The casein mostly affects texture by<br />

adding body <strong>and</strong> the whey proteins add<br />

color <strong>and</strong> flavor.They could be used to cut<br />

costs or modify your texture or flavor.<br />

Again, break them down, for example, for<br />

the lactose usually found in the whey. If<br />

adding more casein or whey, break down<br />

the protein above so you know how much<br />

you’re starting with.<br />

So many things about the milk can<br />

have an effect. The differences in the raw<br />

milk itself, how it was processed, stored<br />

<strong>and</strong> reconstituted, all have their effect,<br />

mostly due to protein quality. You need to<br />

find which of the differences will affect<br />

your caramel <strong>and</strong> then you need to control<br />

them.<br />

Partially hydrogenated vegetable fat —<br />

184.0 g We won’t break the fat down, but<br />

here are the critical numbers of the fat:<br />

• The melt point — the higher the melt<br />

point, the better the st<strong>and</strong>-up, but be<br />

careful going above 92°–95°F as it can<br />

start to give it a waxy texture <strong>and</strong> flavor.<br />

• The solid fat index (sfi)—this will let<br />

you know how sharp a melt curve you<br />

will have. This can influence the flavor<br />

release.<br />

Other factors in deciding are resistance to<br />

oxidation <strong>and</strong> even how the fats are added.<br />

Blending several fats before emulsification<br />

can yield overall softer fats due to<br />

eutectic effect.<br />

Salt — 14.0 g The salt is used primarily to<br />

enhance flavor.<br />

Soy lecithin — 2.5 g The soy lecithin is an<br />

emulsifier, ensuring a good dispersion<br />

<strong>and</strong> homogenization of the fat. Other<br />

emulsifiers can be used to help with specific<br />

needs of your caramel. For example,<br />

gms can be used to help with st<strong>and</strong>-up<br />

or to help with cutting a caramel that is<br />

sticky. Talk to your suppliers to determine<br />

which are best for your needs. Don’t<br />

forget that the milk proteins also help in<br />

emulsification <strong>and</strong> in some cases may be<br />

all you need. Just make sure you have the<br />

level <strong>and</strong> type of emulsifier correct. If too<br />

much, you’re wasting money <strong>and</strong> it could<br />

even contribute to off flavor or texture<br />

<strong>and</strong> if too little, it could oil out.<br />

Other ingredients It is common to use carbonates,<br />

phosphates or other buffers to<br />

adjust the pH of your caramel. If the pH is<br />

too low, below the isoelectric point of the<br />

milk proteins (~4.6), the proteins will precipitate.As<br />

the pH rises, you affect the rate<br />

of the Maillard reaction, but if it is too high<br />

your flavor quality decreases.A good starting<br />

point is a pH between 6 <strong>and</strong> 6.5.<br />

You can use other ingredients to modify<br />

texture <strong>and</strong> flavor, such as various nutmeats<br />

<strong>and</strong> vanilla or vanillin. Starches or<br />

other thickeners can be used to modify<br />

product texture <strong>and</strong> your process.<br />

Putting it all Together<br />

Now rewrite your recipe <strong>and</strong> turn it into<br />

a formula. Our recipe turns into Figure 5. ➤<br />
