Q1. Pectin is a _______ fiber.

1. Water-soluble
2. Less fermented
3. Water-insoluble
4. Both A and B

ANSWER: D. Both A and B

• Explanation: Pectin is a water-soluble fiber. Dietary fiber is often divided into two categories: cellulose, hemicellulose, and lignin are examples of water-insoluble/less fermented fibers, while pectin, gums, and mucilages are examples of water-soluble/well-fermented fibers. D-galacturonic acid is the main component of pectins, which are components of the major cell wall. Water-soluble and gel-forming in general.

Q2. ________ is a galactomannan isolated from the seed of Cyamopsistetragonolobus.

1. Lignin
2. Guar gum
3. Pectin
4. Cellulose

ANSWER: B. Guar gum

• Explanation – Guar gum is a galactomannan extracted from Cyamopsistetragonolobus seeds (guar). The product of partial enzymatic hydrolysis can be employed as a soluble dietary fiber. The physiological effects of this fiber source are consistent with those of soluble fiber. Gum arabic is a substance produced by the acacia tree.

Q4. Fructans selectively stimulate the growth of?

1. Bifdobacteria and Lactobacilli
2. E. coli
3. Clostridia and Bacteroides
4. All of the above

ANSWER: A. Bifidobacteria and Lactobacilli

• Explanation – Fructans are known to be beneficial to one’s health. Asparagus, garlic, leek, onion, Jerusalem artichoke, and chicory roots are just a few of the fructan-rich plant species that are commonly consumed as vegetables. Fructan improves glucose, lowers triglycerides, modifies lipid metabolism, and lowers plasma LPS by acting as a prebiotic. They also promote the growth of Lactobacillus and Bifidobacterium bacteria, which help to lower the prevalence of pathogens in the gut.

Q5. An example of water-insoluble fiber is?

1. Lignin
2. Pectin
3. Gum
4. Mucilage

ANSWER – A. Lignin

• Explanation: The edible sections of plants or comparable carbohydrates that are resistant to digestion and absorption in the human small intestine with complete or partial fermentation in the large intestine are referred to as dietary fiber. Lignin is an example of a water-insoluble fiber. Component of the cell wall that isn’t carbohydrate. Phenyl propane polymer has a complex cross-linking structure. Bacterial decomposition is inhibited.
