Final answer:
MGP Ingredients Inc.'s development of low-carb wheat proteins and starches represents the creation of a new product line, indicating a strategic shift to enter a new market segment and diversify product offerings.
Step-by-step explanation:
MGP Ingredients Inc., after experiencing a significant drop in sales of ethanol and animal feed, shifted focus to develop the first low-carb wheat proteins and starches. This shift can be classified as a new product line. Such a strategic move is undertaken by companies aiming to diversify their offerings and entering into a new market segment with products that are distinct from existing ones. The low-carb wheat proteins and starches represent a new opportunity in response to changing market demands, notably the rise in consumer interest toward low-carbohydrate diets.
