The Harris–Benedict equation (also called the Harris-Benedict principle) is a method used to estimate an individual's basal metabolic rate (BMR).. The estimated BMR value may be multiplied by a number that corresponds to the individual's activity level; the resulting number is the approximate daily kilocalorie intake to maintain current body weight.
The name sago is also sometimes used for starch extracted from other sources, especially the sago cycad, Cycas revoluta. The sago cycad is also commonly known as the sago palm, although this is a misnomer as cycads are not palms. Extracting edible starch from the sago cycad requires special care due to the poisonous nature of cycads. [6]
Amylolytic process or amylolysis is the conversion of starch into sugar by the action of acids or enzymes such as amylase. [ 1 ] Starch begins to pile up inside the leaves of plants during times of light when starch is able to be produced by photosynthetic processes.
Retrogradation can expel water from the polymer network. This process is known as syneresis. A small amount of water can be seen on top of the gel. Retrogradation is directly related to the staling or aging of bread. [3] Retrograded starch is a type of resistant starch. Chemical modification of starches can reduce or enhance the retrogradation ...
Damaged starch can be produced, for example, during the wheat milling process, or when drying the starch cake in a starch plant. [5] There is an inverse correlation between gelatinization temperature and glycemic index. [4] High amylose starches require more energy to break up bonds to gelatinize into starch molecules.
As the starch is hydrolysed, the molecules become shorter and more reducing sugars are present. Therefore, the dextrose equivalent describes the degree of conversion of starch to dextrose . The standard method of determining the dextrose equivalent is the Lane-Eynon titration , based on the reduction of copper(II) sulfate in an alkaline ...
Amylopectin is a key component in the crystallization of starch’s final configuration, [4] [5] [6] accounting for 70-80% of the final mass. [7] Composed of α-glucose, it is formed in plants as a primary measure of energy storage in tandem with this structural metric.
The concept of "protein-sparing modified fast" (PSMF) was described by George Blackburn in the early 1970s as an intensive weight-loss diet designed to mitigate the harms associated with protein-calorie malnutrition [8] and nitrogen losses induced by either acute illness or hypocaloric diets in patients with obesity, in order to adapt the patient's metabolism sufficiently to use endogenous fat ...
