Myths and Truths about Candy • MYTH Candy contributes a lot of the fat & sugar in the American diet. • TRUTH In fact, less than 2% of the fat and 10% of the sugar in our diets are supplied by candy. Most of the fat actually comes from the high-fat animal products we eat. The main sources of sugar in America's diets are sugary beverages, baked goods and frozen desserts. • MYTH Foods high in saturated fats raise cholesterol levels. • TRUTH Contrary to popular belief, not all types of saturated fats raise blood cholesterol levels. Stearic acid, the primary saturated fatty acid found in chocolate, has been shown to have a neutral effect on blood cholesterol levels.
Myths and Truths about Candy • MYTH An ounce of milk chocolate contains about as much caffeine as a cup of coffee. • TRUTH Actually, a one-ounce piece of milk chocolate contains about the same amount of caffeine as a cup of decaffeinated coffee. There is an average of 6 mg of caffeine in both an ounce of milk chocolate and a cup of decaf, while a cup of regular coffee contains between 150 and 655 mg. of caffeine. • MYTH The sugar in candy causes hyperactivity in children. • TRUTH Sugar does not cause hyperactivity in children, despite wide-spread belief to the contrary. Recent studies conducted at Vanderbilt University and the University of Iowa College of Medicine found no evidence that sugar has an adverse effect on children's behavior. • MYTH Candies like jelly beans, gum drops or hard candies are high in calories. • TRUTH Not at all. One butterscotch disc has only 20 calories. Eight gum drops or eight jelly beans (the equivalent of one ounce) contain 115 calories. Even better, most of these candies are fat- and cholesterol-free, making them a healthier treat than many people realize.
Myths and Truths about Candy • MYTH Chocolate is addictive. • TRUTH Although it's true that many people love the taste of chocolate, it is not an addictive food. An addiction is a serious medical condition with specific physical and psychological symptoms. However, the desire for sweet tasting food is a strong biological drive, and it can be satisfied by eating any naturally sweet food or product made with sugar. • MYTH Candy is responsible for most tooth decay. • TRUTH Not so. Any food containing fermentable carbohydrates, such as starches or sugars, can contribute to tooth decay. It all depends on how often we eat and drink these foods and how long they remain in our mouths. Good dental hygiene and regular fluoride treatments are the best ways to prevent cavities.

Properties & Behavior • pH,natural 5,5-6,0, alkali treated 5,5-7,8 • Lemak : ester gliserol kombinasi asam linoleat, oleat, palmitat dan stearat stabil dan resisten untuk menjadi tengik, kr padatan non lemak mengandung antioksidan
Sebagai pembentuk flavor = tgt komposisi Sbgpelapis = menahan/ pembatas agar air/ flavor tidak moving Fungsi Coklat
Tergantung komposisi dan reaksi komponen2 tsb dg bhn lain High grade coklat= flavor bagus Coklat dg kadar lemak tinggi = superior chocolate flavor Penepungan menjadi coklat bubuk = menurunkan senyawa aromatik,namun coklat bubuk plg sering dgnkn dlm pembuatan permen kr mudah diaplikasikan dan menghasilkan flavor dan color yg memuaskan Flavor

Harus mengkilap = kristal cocoa butter harus sekecil mungkin Semakin kecil ukuran kristal = makin smooth permukaannya Sebagai Pelapis
Coklat cenderung m’bentuk bloom= mjd pudar, warna keabu-abuan, shelf life lebih pendek Kontak dg panas = mempercepat bloom Pelapis yg bagus = cukup kuat melindungi bagian center, cukup kuat thd keretakan/ pech slm handling Kristal lemak yg kecil2 = struktur pelapis lebih kuat= dpt mengontrol terbentuknya bloom Chocolate Bloom

(Linda Grayson, “The Pickwick Papers”) • It is not that chocolates are a substitute for love. Love is a substitute for chocolate. Chocolate is, let’s face it, far more reliable than a man. (Miranda Ingram) • Man cannot live on chocolate alone; but woman sure can. (unknown) • This guy found a bottle on the ocean, and he opened it and out popped a genie, and he gave him three wishes. The guy wished a million dollars and poof! there was a million dollars. Then he wished for a convertible, and poof! there was a convertible. And then, he wished he could be irresistible to all women … poof! He turned into a box of chocolates. (unknown)
