Step 1: Understanding the Concept:
Mysost is a unique Scandinavian whey cheese. Unlike traditional cheeses made from curd, whey cheeses are made by concentrating whey proteins and lactose through evaporation.
Step 2: Detailed Explanation:
- Statement (A): Mysost is traditionally a Norwegian whey cheese. While modern versions use bovine whey, "ovine" (sheep) whey was historically significant, and it is a defining product of Norway. Correct.
- Statement (B): The color of Mysost comes from the Maillard reaction (sugar-protein browning) and caramelization of lactose during the long evaporation process. Added cream affects the fat content and final hue. Correct.
- Statement (C): This statement is backwards. By increasing the boiling time and cooking to a higher solids content, the product becomes thicker and sliceable (like Gjetost). To make it more spreadable, the concentration is stopped earlier (lower solids). Thus, the statement is logically flawed in its phrasing. Incorrect.
- Statement (D): Due to high solids content and low moisture, these cheeses have excellent shelf life under refrigeration. Correct.
Based on the options provided in typical dairy technology literature, Statements A, B, and D are accurate descriptions of the product and its stability.
Step 3: Final Answer: (2) (A), (B) and (D) only.
