MCQ (Single Correct) +4 −1

Which of the following type of frozen product requires maximum addition of a given stabilizer?

निम्नलिखित में से किस प्रकार के जमे हुए उत्पाद में दिए गए स्टेबलाइजर (stabilizer) के अधिकतम योग की आवश्यकता होती है?

Stabilizer dosages across frozen dessert categories:

  • Frozen yoghurt contains milk proteins and milk fat that provide substantial natural water-binding capacity, requiring normal stabilizer levels ($0.2\text{--}0.3\%$).
  • Water ices (fruit ices) contain no milk solids or fat (only water, sugar, fruit acids, flavour, and colour); because they have extremely high water content ($70\text{--}80\%$) with no protective proteins, they require the maximum level of stabilizer ($0.4\text{--}0.5\%$ or higher) to prevent coarse ice crystal growth and bleed-out of syrup.
  • Chocolate ice cream has high total solids ($40\text{--}42\%$) due to cocoa, requiring reduced stabilizer ($0.15\text{--}0.2\%$) to avoid heavy/gummy body.
  • Plain pineapple ice cream contains milk solids and requires standard stabilizer dosage ($0.25\text{--}0.35\%$).
Therefore, option 2 (Ices) is the correct answer.

जमे हुए उत्पादों में स्टेबलाइजर की आवश्यकता:

  • फ्रोजन योगर्ट में दूध प्रोटीन और वसा प्राकृतिक रूप से जल बांधते हैं।
  • वाटर आइसेस (Ices) में कोई दूध ठोस या वसा नहीं होती (केवल पानी, चीनी और स्वाद), अतः अत्यधिक जल की उपस्थिति में बड़े बर्फ के क्रिस्टल बनने और चाशनी अलग होने से रोकने के लिए सर्वाधिक स्टेबलाइजर ($0.4\text{--}0.5\%$) की आवश्यकता होती है।
  • चॉकलेट आइसक्रीम में कोको के कारण कुल ठोस अधिक होते हैं, अतः इसमें स्टेबलाइजर सबसे कम डाला जाता है।
  • पाइनएप्पल आइसक्रीम में सामान्य स्तर का स्टेबलाइजर लगता है।
अतः विकल्प 2 (Ices) सही उत्तर है।
