Jack Bean () Tempeh: ACE-Inhibitory Peptide Formation during Absorption in the Small Intestine.

Research Background: High blood pressure is the most significant cause of mortality globally. Some fermented foods include ACE-inhibitory peptides that help fight this disease. The ability of fermented jack bean (tempeh) to inhibit ACE during consumption has not been demonstrated yet.

Impact of Gastrointestinal Digestion Simulation on the Formation of Angiotensin-I-Converting Enzyme Inhibitory (ACE-I) Peptides from Germinated Lamtoro Gung Flour.

The germination of lamtoro gung has been shown to increase the angiotensin-I-converting enzyme inhibitory (ACE-I) activity in previous studies. The 48 h germinated flour had the highest ACE-I activity. Administration of the gastrointestinal digestion (GID) simulation with commercial enzymes was expected to increase the ACE-I activity.

FiberCreme as a Functional Food Ingredient Reduces Hyperlipidemia and Risk of Cardiovascular Diseases in Subjects with Hyperlipidemia.

FiberCreme is a commercial nondairy creamer made with isomalto-oligosaccharides (IMO) that is a source of dietary fiber. A study showed that IMO could decrease cholesterol (CH) and triglycerides, which are factors related to the risk of cardiovascular diseases and insulin resistance. This study evaluated FiberCreme's ability as a functional food ingredient to reduce CH and the risk of cardiovascular diseases in subjects with hyperlipidemic.

In vitro gastrointestinal simulation of tempe prepared from koro kratok ( L.) as an angiotensin-converting enzyme inhibitor.

This study investigated the formation of angiotensin-converting enzyme (ACE) inhibitory peptides from koro kratok beans tempe during gastrointestinal digestion. The absorption of bioactive peptides was also investigated in this study. Koro kratok was fermented by commercial culture including for 48 h.

Bioactive Peptide Tempe Made from (L) DC as an Inhibitor of Angiotensin-I-Converting Enzyme (ACE) in a Digestion Simulation.

(L) DC tempe is a food that functions as an inhibitor of the angiotensin-I-converting enzyme (ACE). The purpose of this research was to study the activity of tempe peptides during the digestive process with pepsin-pancreatin, and absorption of peptides in the small intestine using the inverted intestinal sac method. Our results show that had the highest ACE-inhibiting activity after digestion after fermentation for 72 h (F72).

Physicochemical properties, in vitro starch digestibility, and estimated glycemic index of resistant starch from cowpea (Vigna unguiculata) starch by autoclaving-cooling cycles.

Recently, legumes starch were studied extensively due to high amylose and resistant starch contents, and low glycemic index (GI). We evaluated the impact of autoclaving-cooling cycles (single, triple, five) on the physicochemical properties, in vitro starch digestibility, and estimated glycemic index (eGI) of cowpea starch. Autoclaving-cooling increased the amylose content, water/oil holding capacities, onset, peak, and conclusion gelatinization temperatures.

Characterization of glucomannan from Amorphophallus oncophyllus and its prebiotic activity in vivo.

Porang (Amorphophallus oncophyllus) is local perennial plant rich in glucomannan. The aim of this study was to extract and characterize glucomannan from porang tuber and to evaluate its potency as prebiotic in vivo. The research consisted of the following steps, i.

Coarse brown rice increases fecal and large bowel short-chain fatty acids and starch but lowers calcium in the large bowel of pigs.

Young male pigs were fed a diet formulated from human foods including either boiled white rice plus rice bran or heat-stabilized brown rice at equivalent levels of fiber for 3 wk. Stool and starch excretion were low in pigs fed white rice during the first 2 wk of the experiment. In pigs fed brown rice, their excretion was high during wk 1 but declined in wk 2 while short-chain fatty acid (SCFA) excretion was higher at both times.

Plasma lipids and large bowel volatile fatty acids in pigs fed on white rice, brown rice and rice bran.

Adult male pigs were fed on a diet containing (% of energy) fat 25 starch 55 from white rice and providing 20 g fibre/pig d (diet WR). In two other groups rice bran was added to the diet to provide 43 g fibre/d. One group received the diet unmodified (diet RB), but in another (diet RO) heat-stabilized unrefined rice oil replaced the palm oil.

Dietary fat and fiber alter large bowel and portal venous volatile fatty acids and plasma cholesterol but not biliary steroids in pigs.

Male pigs were fed a low fiber beef diet (control) or that diet with additional fiber either as wheat bran, oat bran or baked beans. Total large bowel digesta and volatile fatty acid (VFA) pools were highest in pigs fed the diet with baked beans, intermediate in those fed the diets with oat bran and wheat bran and lowest in those fed the control diet. In all groups digesta mass and total VFA pools rose from the cecum and then fell to the distal colon, and incremental effects of diet were the same at all sampling sites.
