様態の副詞

The pink pineapple aka Pinkglow pineapple is a  unique, genetically engineered fruit developed  

by food giant Del Monte. Grown in Costa Rica,  it took 16 years to perfect and is in high  

demand. Its distinct pink coloration  comes from a pigment called lycopene,  

the same carotenoid that gives  watermelon and tomatoes their red hue.

In standard pineapples, an enzyme called lycopene  beta-cyclase converts lycopene to beta-carotene,  

resulting in yellow flesh. In Pinkglow  pineapples, this enzyme is muted through  

a technique called RNA interference,  causing lycopene to accumulate instead.

The genetic modification began in 2005  and involved testing four generations  

of the plant between 2010 and 2014  to ensure quality and productivity.

Del Monte has patented this pineapple, making them  the sole producers. The retail cost is notably  

higher due to its scarcity and marketing, ranging  from $10 in grocery stores to up to $39 online.
