Abstract
Cereal grains are ground, slurried in water below the starch gelatinization temperature. Bran, starch granules and protein are removed. .beta.-Glucan is precipitated and dehydrated with alcohol, screened and ground to become a white-colored product with a neutral flavor. The method recovers from 33 to 75 percent of the total natural occurring .beta.-glucan in cereal grains. The .beta.-glucan product is water soluble with purity ranging from 60-90 percent and exhibiting molecular weight of .beta.-glucan ranging from 4.times.10.sup.5 daltons to

Abstract
The subject is a novel apparatus for cultivating organovegetables, which includes an organic medium layer, a vegetable seeds paper membrane, a position-fixing membrane and an insect-proof screen membrane, and which is formed by laminating in order the organic medium layer, the vegetable seeds paper membrane, the position-fixing membrane and the insect-proof screen membrane. These components of the novel apparatus can be prepared into upright rolls which can be cut and applied according to the cultivating area. The novel apparatus is used in

The crowns of mature pineapples ready for harvest are treated with an aqueous medium containing sufficient amounts of a gibberellin to retard withering and senescense of the crowns. The medium is preferably applied to the crowns soon after the pineapples have been harvested. The pineapples treated in accordance with this invention retain a freshly harvested appearance for an extended period of time and make them ideally suited for sale in the fresh fruit market.
