Biscuit which in the end biscuit machine what surprises you the truth of food and nutrition

Cookies are many people obsessed with a class of snack foods. A lot of girls say: I can not drink sweet drinks, no cake, but biscuits really addictive ah! Why do you always say do not deserve to eat cookies? The doctor said soda crackers is not very healthy? Sugar cookies will not sugar bad?

Just a few days ago, a reporter sent me a copy  biscuit machine of the relevant measurement result 10 brands of biscuits, and made a number of problems related to the nutritional value and biscuits. There is no harm to share friends, but also the way to answer the girls confused.

What are the major components of a biscuit is it?

The measurement results very clearly show that the moisture content of various biscuits are very low, because it is baked out, water can evaporate almost lost the. Up biscuit ingredients are carbohydrates, the second component is fat, the third ingredient is protein.

From the measurement results, these 10 samples are carbohydrate content between 55% -67% to 60% more. In other words, from the ingredients, they and biscuits, pie differences like little food staples, is a sugar + flour + oil produced food products. Therefore, we must reduce the staple food to eat the cookies.

2 biscuits in the "carbohydrate" and "sugar" is not the same thing? Saccharide compounds are said to be divided into monosaccharides, disaccharides and polysaccharides, they have what is different? People can not eat sweetened lifetime desert?

Yes, the food labels above out of the "carbohydrate" includes monosaccharides sum, disaccharides and polysaccharides. Which typically does not include dietary fiber, although from a chemical standpoint, the vast majority of dietary fiber is a carbohydrate, but they can not be digested and absorbed.

Possible chemical basis of my friends will be weaker a little dizzy. So explain it. Theoretically, carbohydrates (carbohydrates) also known as sugars (saccharides), refers to a class of compounds of sugar units. However, the convention said, saying the so-called sugar (sugar), is a small molecule, sweet carbohydrates, including monosaccharides, as well as part of the disaccharide (sucrose, maltose and lactose). Starch (one digestible polysaccharides) can not be called sugar.

However, the starch is glucose units connected by made. After long chain starch molecules is hydrolyzed gradually into smaller pieces, eventually become maltose and glucose, which are sweet. So, after carefully chew food starch, I will feel a little sweet, because saliva amylase to starch hydrolysis became a sweetness of maltose (malt sugar, maltose Kanto sugar is done).

In fact, the starch in vivo physiological role played in that role in glucose. People eat is unsweetened starch absorption in the intestine is sweet glucose. Finally the body is used as the "energy" substance is glucose. So, even a lifetime to eat sugar sugar glucose, never eat sweets, but also completely without prejudice to health. Because the body needs is glucose, eat enough food, potatoes, beans, sufficient starch, glucose is completely able to fully supply the needs of the body.

3 Some biscuits known as "sugar-free" or "no sugar", what is the concept? National standards?

The so-called sugar-free, no added ingredients that contain sugar. Soft white sugar, white sugar, sugar, brown sugar, brown sugar, brown sugar, brown sugar ... people daily eat almost all belong sucrose sugar, but the difference between purity and crystalline way. Sugar is extracted from sugar cane or sugar beets out. As for sugar, in addition to sugar-free outside, sweet ingredients maltose, glucose, fructose, high fructose corn syrup instead of sugar, and many can not be added.

According to GB 28050-2011 "national food safety standard pre-packaged food nutrition labels General", in which the sugar content is less than 0.5 g / 100 g (solids) or 100 mL (liquid) can claim "sugar-free." Referred to herein, "sugar"  biscuit machine  does not include starch, but include sucrose, maltose, fructose, glucose, sugar and other sweet.

Some products says "no sugar", because it may add a "maltose syrup," "glucose syrup" such ingredients, although not part of sucrose, but as there is a sweet, regarded as sugar. These foods may already contain natural sugars, such as dried fruits, originally sugary. So these products can not say "sugar-free" word, only stressing that "no added sugar" or "no added sugar."
