Definitions

  • This invention relates to an iron fortified tea and a process for manufacture thereof wherein tea may be black tea or green tea of leaf grade, fannings grade, dust grade or any mixture thereof. Tea being most widely consumed beverage world over, the iron fortified tea of the present invention has vast economic significance as well as is of great importance to public health as it would help in reducing iron deficiency of population through the consumption of tea beverage prepared from iron fortified tea of the present invention.
  • Iron deficiency anemia is a serious nutrition related health problem, affecting more than 3 billion people in the world. In India, the situation is even worse where Iron deficiency anemia is more than 70% among the persons in lower age group and more than 50% among the persons in other age groups and is spread across demography and all age groups. While iron deficiency is one of the direct causes of anemia, it is also the cause of various other physiological disorders like energy deficiency, poor growth and development. Therefore iron fortification in food, particularly through tea, which is widely consumed across in India, is considered as a key measure to provide the necessary dietary iron as source to minimize the effect of iron deficiency and the risk of iron deficiency induced anemia.
  • Tea beverage is known to have an inhibitory effect on the absorption of iron in the food consumed, particularly when tea beverage is taken immediately after or along with the food.
  • This inhibitory effect of tea beverage is due to the presence of tea polyphenols, which complex with the iron in the food thereby inhibiting its bioavailablity.
  • This inhibitory effect of tea beverage on the absorption of iron of food particularly when consumed with or immediately before tea beverage could be mitigated by fortification of tea with an iron salt.
  • the problem associated with such approach of fortification of tea with an iron salt is that addition of any of the commonly available iron salts to tea for the purposes of such iron fortification causes complexation of tea polyphenols with such iron salts which results in discoloration of tea.
  • the beverage prepared from the tea fortified with such iron salts therefore lacks the normal appearance and taste of regular tea and therefore would not be accepted for consumption by the tea consumers just like a regular tea beverage.
  • the present invention overcomes this problem and has identified an iron salt and developed a process for iron fortification of tea with the identified iron salt, after considerable research and development with various iron salts, which does not result in any discoloration of tea as the identified iron salt does not interact with tea polyphenols. There is, therefore no change in the tea profile and taste character and hence no difference between tea beverages prepared from the iron fortified tea of the present invention as compared to the tea beverage prepared from the regular tea.
  • the tea beverage prepared from the iron fortified tea of the present invention can be taken by consumers like a regular tea beverage with additional beneficial effects of iron enrichment through the consumption of the tea beverage.
  • an iron fortified tea and a process for manufacture thereof is one of the breakthrough inventions.
  • Tea beverage which is one of the most widely consumed beverage at all levels in the society, has a negative association with respect to Iron, due to its interaction with Iron resulting in discoloration of the liquor making it undesirable to consumers.
  • the present invention provides iron fortified tea, in which the Iron added do not interact with tea in solution and hence the liquor is not affected and at the same time has a texture like a regular tea and beverage prepared therefrom has similar taste characteristics as that of regular tea and also has enhanced bio-availability of iron.
  • the Iron deficiency being one of the leading causes of anemia and several other diseases, this invention will give a long term benefit in combating iron deficiency, by providing dietary iron through Tea and that would impact the general health status of the population.
  • the final dried iron enriched tea provided by the present invention has 99.5 to 99.88% of regular tea, 0.1 to 0.3% of iron salt and 0.02 to 0.2% of starch base, wherein regular tea is black tea or green tea in leaf grade, fannings grade, dust grade or any mixture thereof.
  • the iron enriched tea is manufactured by uniform mixing of a dried concentrate with regular tea in the ratio of 1:4.
  • the dried concentrate is prepared by spraying the iron solution over regular tea and drying in a fluid bed drier in the temperature range of 70 to 90 degree C till the moisture content is less than 5%.
  • the iron solution for this purpose is prepared by adding an iron salt to a homogenized starch base prepared as per the present invention and maintained at a temperature in the range of 60 to 70 degree C, wherein the iron salt is selected from ferrous bis glycine sulphate and ferric trisglycinate.
  • An object of the present invention is therefore to provide an iron fortified tea and process for manufacture thereof wherein the tea manufactured has the same texture as that of regular tea and the tea beverage prepared therefrom has taste and characteristics of a regular tea beverage.
  • Another object of the present invention is to provide an iron fortified tea which provides minimum of 20mg dietary iron in lOOg tea.
  • Each cup of the tea beverage prepared from the iron fortified tea of the present invention provides minimum 0.4mg iron. If three cups of such tea beverage are consumed per day, these would provide minimum 1.2mg of iron that would meet minimum of 4.5% of the recommended daily allowance of 28mg of Iron per day.
  • Still another object of the present invention is to provide an iron fortified tea which has higher bioavailability of iron as compared to other iron fortified foods and beverages, using different iron salts which are typically used for the food and beverages iron fortification such as Ferric pyrophosphate, Ferrous sulfate etc.
  • iron salt used for fortification is ferrous bis glycine sulfate or ferric trisglycinate.
  • the amino acid (in this case Glycine) in the case of these iron salts is bonded to Iron, leaving no vacant orbital in the iron atom, which prevents Iron present in these salts from complexing with polyphenols and other similar molecules, thereby iron remains more bioavailable for absorption in the digestive tract.
  • Still further object of the present invention is to provide an iron fortified tea wherein the dietary iron fortification in tea does not lead to any change in color or other organoleptic properties of the tea and the tea beverage is prepared from the iron fortified tea of the present invention using the same process as used for the preparation of regular tea beverage.
  • Yet further object of the present invention is to provide an iron fortified tea and process for manufacture thereof wherein the process enables uniform distribution of dietary iron in the tea as well as in the beverage prepared therefrom.
  • Even further object of the present invention is to provide an iron fortified tea which has a shelf life of six months in the pack.
  • the lOOg of the final product of dried iron fortified tea of the present invention comprises following ingredients expressed as weight percentage of the product:
  • Iron salt - 0.1 - 0.3% preferably 0.15 -0.25%
  • Starch base 0.02 to 0.2% preferably 0.05 to 0.1%
  • the process for manufacture of the iron fortified tea comprises the steps of:
  • Deionised water is heated in the range of 50-85 Deg C preferably in the range of 65-75 Deg C.
  • the minimum temperature of 50 Deg C is necessary as below 50 Deg C, the ingredients are not completely soluble in the said deionised water and therefore when iron salt is added to the said water, it does not result in uniform dispersion of the ingredients in the water.
  • Starch base is added to such pre-heated water and is homogenized for at least 15 minutes using a Silverson homogenizer maintaining temperature in the range of 65 to 75 degree C, so as to ensure proper mixing and distributing of ingredients evenly in the solvent.
  • Starch base and deionised water are taken in the ratio in the range of 1:50 to 1:75 in weight by volume of deionised water
  • An iron solution is prepared by addition of an iron salt to the homogenized starch mix obtained by step (a) and mixing for at least 15 min, ensuring maintaining of temperature not below 50 Deg C but preferably in the range of 60-70 Deg C.
  • Iron salt and the homogenized mix are taken in the weight by volume ratio of around 1:20.
  • the iron salt is selected from ferrous bis glycine sulphate and ferric trisglycinate that has 10 to 20% iron.
  • the iron solution obtained by step (b), with a solid content of 4 - 7%, is sprayed over regular tea and mixed for minimum 5-10 min in a Forberg mixer, which has an axial spray arrangement and paddle type blenders, to ensure uniform distribution of iron salt in the tea.
  • the regular tea may be leaf grade, fannings grade, dust grade or any mixture thereof.
  • the mixture of iron solution and regular tea after thorough mixing is dried in a fluid bed drier at a temperature between 70 to 90 Deg C to a moisture less than 5%, thereby obtaining the dried concentrate iron fortified tea.
  • the ratio of volume of iron solution to the regular tea over which it is sprayed is in the range of 1:5 to 1:6 in volume by weight of regular tea.
  • step (c) The dried concentrate obtained by step (c) is then mixed with regular tea in the ratio of 1:4 by weight in a rotary blender or vertical static blender to ensure uniform distribution of Iron in the desired level.

Abstract

L'enrichissement de thé en utilisant l'un quelconque des sels de fer actuellement connus conduit à la complexation de fer avec des polyphénols de thé lorsque le thé est infusé, conduisant à la décoloration de l'infusion et lui donnant un goût désagréable. La présente invention résout ce problème en identifiant des sels de fer et concerne un procédé de fabrication de thé enrichi en fer en utilisant les sels de fer identifiés, où le sel de fer identifié n'interagit pas avec les polyphénols de thé, lorsque la boisson est préparée. Le thé enrichi fabriqué a un aspect similaire au thé normal et la boisson de thé préparée à partir d'un tel thé enrichi en fer par le même procédé que celui utilisé pour un thé normal a un aspect et un goût similaires à une boisson préparée à partir de thé normal avec le bénéfice additionnel de l'enrichissement en fer pour les consommateurs. Cette invention est applicable à la fortification de thé noir et de thé vert.
