This invention offers the method of producing the seaweed biomath which is combined with one or more other for food component, the seaweed oil, the food composition which includes minute seaweed biomath, all the minute seaweed cells, and/or the minute seaweed oil, and the constitution which catches, by combining seaweed biomath or the seaweed oil with the other for food component. With desirable execution form, as for the minute seaweed component, it grows heterotrophic, it is derived from the minute seaweed culture which propagates, the seaweed cell in this case includes 10% seaweed oil at least at dry weight.本発明は、1つ以上他の食用成分と組み合わせた藻類バイオマス、藻類油、微細藻類バイオマスを含む食物組成物、全微細藻類細胞、および/または微細藻類油、ならびにかかる組成を、藻類バイオマスまたは藻類油を他の食用成分と組み合わせることによって作製する方法を提供する。好ましい実施形態では、微細藻類成分は、従属栄養的に成長し、繁殖した微細藻類培養物に由来し、この場合の藻類細胞は、乾燥重量で少なくとも10%の藻類油を含む。
