Definitions

  • This invention relates to the cooking of starch-based foodstuffs.
  • Nutrients are chemicals found in foods that are critical to human growth and function. There are six groups of essential nutrients: carbohydrates, lipids, proteins, vitamins, minerals and water. Carbohydrates together with lipids and proteins provide energy for the body, particularly for the brain and for physical exercise.
  • Starch food including rice, wheat, and potato is a staple food for almost all the world and is the main source of carbohydrates. Our bodies easily digest most cooked starches, in which alpha bonds link the numerous glucose units together. Starch food, like rice, bread, pasta and potato are thus important for health and generally eaten daily as a primary food source.
  • Cooking starch-based food normally makes the starch fully gelatinized which can be quickly digested and absorbed. This then increases the blood glucose level and insulin response after consumption.
  • the quick increase of blood glucose may promote metabolic diseases such as obesity and diabetes. Indeed, studies have shown a close relationship with the incidence of diabetes.
  • Starch that is slowly digested i.e. "slow digestion starch” or which is resistant to the human digestive system (i.e. “resistant starch”) may reduce the incidence of metabolic diseases and at the same time promote gut health.
  • Starch accounts for about 90% of the dry weight of potato and milled rice.
  • the starch granule can be divided into several levels according to the dimensions, as shown in Fig. 1 which is copied from Gilbert R. G. et al., (2013): "Improving human health through understanding the complex structure of glucose polymers", Analytical and Bioanalytical Chemistry. 405:8969-8980.
  • the image 1 represents starch at the nm scale which is defined as level 1.
  • Amylose 2 and amylopectin 3 have dimensions of the order lOnm which is defined as level 2.
  • Clusters 4 have dimension of the order 10 to lOOnm which is defined as level 3.
  • Lamellae which are crystalline 5 and amorphous 6 have dimension of the order ⁇ , and are defined as level 4.
  • Granules 7 have dimension of the order ⁇ , which is defined as level 5 and grains 8 have dimension of the order mm, which is defined as level 6.
  • the glassy (amorphous) region of the starch first becomes soft and rubbery followed by the melting of the crystalline regions within the starch granule. After full or partial starch gelatinization, the starch granules begin to swell and this is accompanied by leaching of amylose from the starch granules.
  • the gelatinized starch contains no crystalline region and therefore is readily attacked by the digestive enzymes.
  • resistant starch The starch that is un-digestible is called resistant starch ("RS").
  • resistant starches are divided into five groups:
  • RSI physically inaccessible - starch embedded in protein and in cell wall matrices in cereal grains
  • RS2 raw starch such as in a banana
  • RS4 Chemically modified, such as cross-linked to form a structure that is not easily accessible for enzymes
  • RS5 Amylose-lipid complex.
  • RS 1 and RS2 are naturally occurring raw starches and disappear and are fully gelatinized by cooking.
  • RS3 is only formed if the cooked starch-based food is cooled for a certain period (i.e. a starch retrogradation process).
  • RS4 is formed by chemical modification in industry.
  • the starch granule is constituted by two types of molecules: amylose and amylopectin.
  • amylose could form inclusion compounds with lipids (e.g. free fatty acids) to form the amylose-lipid complex, RS5. This gives the opportunity to generate RS5 during starch food
  • RS5 is non-digestible in the human small intestine but partially fermented in the large intestine. Therefore, consuming food containing the RS5 starch food reduces the food calorie density, and increases the dietary fiber intake. This slow digestion of RS5 could reduce obesity, alleviate diabetes symptoms, and promote gut health. During the intestinal bacteria fermentation of resistant starch, a short-chain fatty acid called butyrate is produced. Some research has also suggested that butyrate reduces the risk of cancer
  • Fig. 2 shows a resistant starch measurement method known as a differential scanning calorimetry (DSC) thermogram. It shows the heat flow into the starch-based food product as a function of temperature. It is adapted from Paton, David. (1987). Differential scanning calorimetry of oat starch pastes, Cereal chemistry. 64(6): 394-399.
  • the first valley 10 corresponds to gelatinization and the second valley 12 corresponds to amylose-lipid melting. This method thus can be used to detect the presence of RS5. Two scans are shown to confirm the amylose-lipid formation.
