Q1. Grapefruit oil comprises of _______ and nootkatone, which gives characteristic flavor and aroma to the oil.

1. Terpene thiols
2. Geranial
3. Limonin
4. Dilactone

ANSWER: A. Terpene thiols

• Explanation: Grapefruit oil contains Terpene thiols and Nootkatone, which give the oil its distinctive flavour and scent. Desludger is used in the FMC system to separate slurry into an oil-rich emulsion, which is then used to extract oil from the fruit peel at the juice extractor. Heat treatment of juices is necessary because it should deactivate the pectinase enzyme (pectin methylesterase). Further heating should be avoided to avoid pectin and sugar hydrolysis, which can lead to cloud loss and gelation.

Q2. _______ was originally termed as the “Chinese Restaurant Syndrome”.

1. Benzoate symptom complex
2. MSG symptom complex
3. Paraben symptom complex
4. Nitrite symptom complex

ANSWER: B. MSG symptom complex

• Explanation – Monosodium glutamate, often known as sodium glutamate or MSG, is the sodium salt of glutamic acid, which is one of the most prevalent non-essential amino acids found in nature. “Chinese Restaurant Syndrome” was the initial name for the “MSG symptom complex.” Humans have the capacity to absorb glutamate, which has a relatively low acute toxicity, under normal circumstances. Pressure on the head, seizures, chest pains, headaches, nausea, burning sensations, and facial tightness have all been reported.

Q3. According to the source /origin, conjugated linoleic acid has been grouped under ______.

1. Plant-derived foods
2. Animal-derived foods
3. Microbial foods
4. All of the above

ANSWER – B. Animal-derived foods

• Explanation:  CLA stands for conjugated linoleic acid, a phrase that refers to the positional and geometric isomers of linoleic acid present in animal fats including beef, lamb, and dairy products. In the rumens of ruminants, CLA is generated via microbial fermentation of PUFAs and isomerization of linoleic acid.

Q4. According to the organ system, Probiotics are beneficial for?

1. Cardiovascular system
2. GI tract
3. Skeletal system
4. Nervous system

ANSWER: B. GI tract

• Explanation: Probiotics are living bacteria and yeast that are beneficial to your overall health, particularly your digestive system. Through their local effects and/or immune system impacts, probiotics can prevent or alleviate diarrhea and inflammation. Probiotic bacteria in the gut are hypothesized to occupy binding sites on the mucosa, preventing harmful bacteria from attaching to it.

Q5. Microbial-derived functional foods include?

1. Probiotics and Prebiotics
2. Symbiotics
3. Postbiotics
4. All of the above

ANSWER: D. All of the above

• Explanation – Symbiotics are dietary supplements that combine probiotics and prebiotic food components in a synergistic way to promote the survival and implantation of live microbial dietary supplements in the gastrointestinal system, either by encouraging growth or metabolically activating the bacteria. New microbiome-modulating interventions, such as synbiotics, postbiotics, microbial consortia, live biotherapeutic products, and genetically modified organisms, are emerging alongside and adjacent to the probiotic and prebiotic fields, with renewed interest in polyphenols, fibers, and fermented foods.
