As a agri product exporter I may be able to shed some light on this. Ever since the superfood hype, some 10 years ago, agri products from Peru have been popular. PromPeru, an organisation that promotes Peru Tourism and Peruvian products, even uses the slogan "Superfoods from Peru" for all agri promotional activities. The slogan was actually used by my company but I am fine with them using it.
Products such as quinoa drove Peru's superfood export to record heights in 2012-2014. The other health food hype, raw food, also worked well for Peruvian products. Raw food is basically unprocessed food or processed until a certain degree/temperature/pressure. Products such as raw cacao, raw maca powder became flagship products for Peru agri promotion. Basically the same product as always, but with the 'raw' label added.
A third factor that is driving agri is the investment into coffee and cacao production. Several organizations, mostly sponsored using funds from the USA and EU, are trying to convert farmers to product cacao or coffee instead of coca. It seems a fairly successful project as over the last 5 years, cacao production has almost doubled.
The industry is growing up. The majority of exports now originates from small exporters. Exporters that approach the international marketplace through trade shows, websites, social media campaigns.
As an industry we are not there yet. On a sales, marketing and product innovation level we are still lagging behind countries such as Chile, Brazil and Argentina. But each year the industry is learning, growing and improving. It is a fun industry to work in with the many products that Peru has to offer. Hundreds, sometimes unique, products have not been commercialized yet. Especially agri products form the jungle. Out of Peru's 200 types of chili, only 3 are exported. Only 40% of all fruit types is exported, etc, etc.
