| Research Abstract |
The objective of our research was, upon establishing that elderly patients confined to a geriatric nursing home were suffering from constipation, to improve intestinal environment without diarrhea by having them ingest high-fiber foods. The research conducted this year was carried over from 2005. The research involved first establishing whether elderly patients were suffering from constipation, and the second that effect of ingestion of agar jelly and oligosaccharide on defecation of elderly patients. Development of food processed through vacuum cooking was also examined. The results were as follows.
1.The actual condition of constipation of elderly patients
Elderly patients confined to a nursing home for geriatrics were classified according to the amount of nursing assistance required. Meal form, food intake, excretion method, defecation frequency, and purgative use frequency were investigated. Due to reduced chewing and swallowing function, the meal form of minced diet and fluid diet i

ncreased in proportion to the amount of nursing assistance required. 21 patients were provided the purgative doses each day and 59 patients were provided doses when they had not defecated in 2 or 3 days. In spite of increase of the purgative dose, the patients' defecation frequency was decreased as the amount of nursing assistance increased, Average defecation frequency of all elderly patients was 5.7 times a week, and 4.0 times a week for nursing assistance level 5 patients.
2.Effects of ingestion of agar jelly and oligosaccharide on intestinal environment
The agar jelly ( 0.5g agar content) was ingested for 5 months every breakfast. Defecation frequency of all 80 elderly patients increased to 6.8 times a week, and amount of feces moisture decreased to 75.0%, whereas it was 81% prior to agar jelly ingestion. As for intestinal flora, the total amount of bacteria was increased to log 8.6 cfu of 1g feces after agar jelly ingestion, whereas it was log 7.9 cfu prior to agar jelly ingestion. The effect of ingesting agar jelly together with 3g of oligosaccharide was furthermore studied on 10 elderly patients for 4 months. The study showed an increase to log 6.4 cfu from log 2.0 cfu in amount of Bifidobacterium in the intestines. These results indicate that ingestion of agar jelly and oligosaccharaide can further improve intestinal environment of elderly patients.
3.The examination of processing several foods through vaccuum cooking under various conditions
Root vegetables were processed through vaccuum cooking and usual cooking by changing heating temperatures and size of the food and their physical property were compared. As the result, the shape of the food did not collapse and became soft when processded through vaccuum cooking. Less
