Tea, especially green tea, is known to be a rich source of polyphenols, making it a popular choice for those looking to boost their antioxidant intake.
11.
Which type of tea is produced by complete fermentation process?
Correct Answer
A. Black tea
Explanation
Black tea is produced through a complete fermentation process. During fermentation, the tea leaves are fully oxidized, resulting in a dark color and robust flavor. This process involves exposing the leaves to oxygen, which causes chemical changes in the leaves and gives black tea its distinctive characteristics. Red tea, green tea, and oolong tea undergo different levels of oxidation and are not produced through a complete fermentation process.
12.
Beverage made by liquefying the whole fruit where at least 10 % of the volume of undiluted drink is whole fruit
Correct Answer
A. Fruit drink
Explanation
A fruit drink is a beverage made by liquefying the whole fruit, where at least 10% of the volume of the undiluted drink is whole fruit. This means that a fruit drink contains a significant amount of actual fruit, giving it a natural flavor and potentially some nutritional value. It is different from fruit syrup, which is typically a concentrated sweetener made from fruit, and fruit cordial, which is a sweet fruit-flavored concentrate that is diluted before consumption. Fruit juice, on the other hand, is the liquid extracted from the fruit, without any additional ingredients.
13.
Which of the following contains higher iron content?
Correct Answer
B. Jaggery
Explanation
Jaggery contains higher iron content compared to the other options. Jaggery is a traditional sweetener made from sugarcane juice or palm sap, and it undergoes minimal processing, retaining more of its natural nutrients. It is rich in iron, which is essential for the production of red blood cells and the prevention of anemia. On the other hand, sugar, honey, and isomalt do not contain significant amounts of iron. Therefore, jaggery is the best choice for individuals looking to increase their iron intake.
14.
The colour of fresh honey is related to its _____________________content.
Correct Answer
B. Mineral
Explanation
The color of fresh honey is related to its mineral content. Honey gets its color from the minerals present in the nectar collected by bees. Different types of flowers and plants contain varying amounts of minerals, which can result in different colors of honey. The minerals also contribute to the overall flavor and nutritional value of honey.
15.
The thread stage of sugar is achieved at ____________°C.
Correct Answer
B. 110-112°C
Explanation
The thread stage of sugar is achieved at 110-112°C. This temperature range is the point at which a sugar syrup forms threads when dropped from a spoon. At this stage, the sugar syrup has reached a high enough temperature to form a thick, sticky consistency that can be pulled into threads. It is important to reach this stage when making certain candies and desserts that require a specific texture.
16.
Caramelization takes place at a temperature ______ when liquid becomes brown.
Correct Answer
C. 170°C
Explanation
Caramelization is a process in which sugar molecules break down and form new compounds, resulting in a brown color and a rich flavor. This process occurs when the temperature reaches a certain point. In this case, the correct answer is 170°C, which indicates that caramelization takes place at this temperature when a liquid becomes brown.
17.
Crystallisation occurs only if the solution is _________________________.
Correct Answer
D. Supersaturated
Explanation
Crystallisation occurs only if the solution is supersaturated. This means that the solution contains more solute than it can normally dissolve at a given temperature. When a supersaturated solution is disturbed or cooled, the excess solute starts to come out of the solution and forms crystals. In contrast, saturated solutions have the maximum amount of solute dissolved at a given temperature, while undersaturated and unsaturated solutions have less solute than the maximum amount that can be dissolved.
18.
Which of the following is a crystalline candy?
Correct Answer
A. Fudge
Explanation
Fudge is a crystalline candy because it is made by heating sugar, butter, and milk until it reaches a soft-ball stage, and then beating it vigorously to create tiny sugar crystals. These sugar crystals give fudge its smooth and creamy texture. Unlike fudge, brittle is a hard and crunchy candy made by boiling sugar and water until it caramelizes, while caramel is a chewy candy made by heating sugar and cream. Chocolate, on the other hand, is not a crystalline candy as it is made from cocoa solids, cocoa butter, and sugar, and does not have a crystalline structure.
19.
Which of the following is a non-crystalline candy?
Correct Answer
B. Brittle
Explanation
Brittle is a non-crystalline candy because it does not have a crystalline structure. Unlike fudge, fondant, and chocolate, which have a smooth and creamy texture, brittle has a hard and crunchy texture. It is made by boiling sugar and water until it reaches a high temperature, causing it to harden quickly when cooled. This rapid cooling process prevents the formation of crystals, resulting in a non-crystalline candy.
20.
Firm ball stage of sugar cookery is required for preparation of __________________.
Correct Answer
D. Laddoo
Explanation
The firm ball stage of sugar cookery is required for the preparation of Laddoo. This stage refers to the point when a small amount of sugar syrup is dropped into cold water and forms a firm ball that holds its shape but is still pliable. This consistency is crucial for making Laddoo, a traditional Indian sweet made with sugar, ghee, and various ingredients like nuts, coconut, or semolina. Achieving the firm ball stage ensures that the Laddoos will have the right texture and hold their shape when formed into round balls.
