Kraft Foods Inc. (KFT), while preparing for its own split later this year, agreed to sell a majority stake in its Back to Nature line of natural-food products to a private-equity firm that focuses on acquiring smaller, overlooked brands from large corporations.

Financial terms weren't disclosed on the deal--expected to close in October--but the purchaser, Brynwood Partners, typically does deals less than $125 million in size.

Kraft has sold two other brands to Brynwood, but this time the food giant is keeping a minority stake, said to be between a quarter and a half. Kraft's insistence on retaining a share in the maker of crackers, cookies, granola and trail mixes reflects the potential it sees in the brand, but one that the company felt couldn't be achieved within its massive corporate structure, where Kraft steers more money toward its largest, most profitable brands, like Oreo cookies.

"Back to Nature does not have the kind of scale for us that will get it the resources that could get it the growth that it should," Kraft spokesman Michael Mitchell said. As a result, the brand will go to Brynwood, whose latest buyout fund has about a tenth of Kraft's total marketing muscle. Last year, Kraft spent $3.1 billion on advertising, research and development.

The brand, which Kraft bought in 2003 for an undisclosed amount, operates in the faster-growing natural-foods space and uses less-processed ingredients. It will be held through a joint venture between Brynwood and Kraft. While Kraft will have board representation in the joint venture, Brynwood will manage everyday affairs.

Brynwood Senior Managing Partner Henk Hartong III plans to bring to Back to Nature what it has lacked recently, including more new products and more focused marketing. He sees the brand having latitude to expand into new categories, like salty snacks and frozen foods, and becoming a more formidable challenge to the likes of Annie's Inc. (BNNY), a maker of organic macaroni-and-cheese and other snacks who had a highly successful initial public offering earlier this year.

Back to Nature is "a good solid performing business that we think can do more," Mr. Hartong said. Annual sales are between $50 million and $75 million, but cookies, crackers and trail mix have increased sales at roughly 20% a year over the past three years, Mr. Mitchell said.

Eventually, Kraft's stake will become part of Mondelez International Inc., the global snacks company that Kraft will be left with after spinning off its North American grocery business, Kraft Foods Group, on Oct. 1. Back to Nature also has a macaroni and cheese product, which will be sold by Kraft Foods Group under a licensing deal.

Brynwood, over its 28-year history, has become a haven for carve-outs of small consumer brands, acquiring three dozen brands from various corporate sellers, including Procter & Gamble Co. (PG), Unilever N.V. (UN) and PepsiCo Inc. (PEP). Several brands have thrived outside the shadow of the corporate parent. The Zest soap brand, which Brynwood acquired from P&G in January 2011, has increased sales 25% already, Mr. Hartong said.

Brynwood had bought the cookie brand Stella D'Oro and the health bar Balance Bar from Kraft. Stella D'Oro was a tough investment for Brynwood, which dealt with a lengthy labor dispute at a Bronx, N.Y., factory before selling the brand to Snyder-Lance Inc. (LNCE) in 2009 for $23.9 million. But Brynwood did manage to increase the company's sales 30% during its ownership.

Balance Bar, acquired in late 2009, has since seen sales return to single-digit growth, after declining in the years before its involvement, Mr. Hartong said.
