Description

CULTURED MILK DRINK
Technical Field
This invention relates to a milk-based drink that promotes a healthy well-being. Background of the Invention
In modern society, there is an increasing need for a refreshing yet nutritional drink. Mineral water, energy drinks and soft drinks are widely consumed. However, these drinks typically have little or no nutritional value and may have, in the case of soft drinks, high sugar contents.
Yogurt is a form of fermented milk curdled to a smooth, creamy or custard-like consistency by lactic acid-producing micro-organisms. The production of natural yogurt entails the implant of a beneficial culture of Lactobacillus bulgaricus and sometimes Lactobacillus acidophilus in milk which is then allowed to incubate until these particular species of bacilli establish the proper pH in the milk, after which the milk is chilled to inhibit growth of undesirable microflora.
Because of rising public demand, yoghurt is now factory-produced in a large scale and widely sold in supermarkets. Electrically-heated yogurt makers for do-it-yourselfers are also available so that yogurt can be made at home to suit individual taste. In producing yogurt at home, a yogurt starter in the form of plain yogurt or a commercially available dried yogurt culture is added to whole or skimmed milk. But whether yogurt is factory produced or home made, the processing thereof is time consuming, for it takes many hours of fermentation under proper conditions for the natural yogurt to develop fully.
When yogurt containing an active culture is consumed, some bacilli pass unharmed through the stomach, for these species favour an acid medium and are therefore not totally destroyed by gastric juices. But when the bacilli find their way into the intestines, they may implant a favourable flora. In any case, whether or not an implant is effected, beneficial vitamins are ingested.
Yogurt is believed to have medicinal value in the control of intestinal fermentation in that it contributes bacteria which establish themselves in the lower intestine and predominate over putrefactive types. Because of this characteristic, yogurt is often prescribed to patients who are required to take large doses of antibiotic drugs. These drugs, as a side effect, act to kill beneficial intestinal bacteria, and it is often necessary, therefore, to replenish such bacteria.
Yogurt drinks have also become popular. Such drinks may be prepared by mixing yogurt with milk or fruit juice in a blender.
To increase its appeal, the sharp, tangy taste of plain, unflavoured yogurt, which heretofore made yogurt unacceptable to many people, has been masked in many yogurt products with fruit and sweeteners. This practice has resulted in a flavoured yogurt product that is more palatable to a wider segment of the population. However, the use of these additives has been accompanied by an increase in product calorie content.
There is a requirement for a milk-based drink that provides a healthy well-being. Summary of the Invention
The invention provides in one form a cultured milk drink comprising: bicultured milk 10-90 parts w/w; unrefined raw tropical sugar 5-20 parts w/w.
Preferably the unrefined raw tropical sugar is selected from cane sugar and palm sugar.
Preferably the unrefined raw tropical sugar is a combination of cane sugar and palm sugar.
Preferably the cultured milk drink includes finely divided nuts and grains.
Preferably the cultured milk drink includes tropical fruit juices or pulps.
Preferably the cultured milk drink includes flavouring concentrates or essences. Detailed Description of the Invention
The bicultured milk suitable for the present invention is prepared by culturing full fat (4% w/w) cows' milk. However, low fat cows' milk may be used as well as milk to which skim milk powder has been added. The bicultured milk is prepared by adding mild cultured yogurt to the milk at an approximate level of 5% v/v. The milk is then mixed and heated to 9O0C and cooled to approximately 400C to 45°C. A further amount of the mild cultured yogurt is then added and mixed. The mixture is held at 4O0C to 45°C for 6 to 8 hours. The bicultured milk so produced is not sour or gelled compared to conventional yogurts. This means that less sugars are required to be added to provide palatable products.
Palm sugars are derived from palm trees. More than one kind of palm yields sugar, among them the toddy or kitul palm (Caryota urens); palmyra palm (Borassus flabellifer); coconut palm (Cocos nucifera); sugar palm of India (Phoenix sylvestris); sugar palm of Java and Malaya (Arenga saccharifera). Those most prized are the palmyra and kitul sugars, and it is usually these which are bottled as thick palm honey of pouring consistency. When the palms are from 15 to 20 years old, the commence flowering and it is only then that they yield the sweet sap from which palm sugar is made. The sap flows when the inflorescence is tapped, but first it must be beaten (gently) with a mallet for a couple of days. A small slice is taken off the end and a receptacle (usually an earthenware pot or gourd) hung close to the cut to collect the sap each night. The sap is known as "sweet toddy". The fresh sweet toddy is boiled down shortly after collection to make palm syrup and palm sugar.
The unrefined raw tropical sugars are preferably palm sugar and cane sugar. Unrefined cane sugar is made from sugar cane, and the preferred form is jaggery. Jaggery is a type of raw sugar that is similar to gula melaka and is used in Indian cooking in the same way. The flavour and heady aroma are somewhere between brown sugar and molasses with a hint of fermentation. In production, first the sugar cane is crushed through a sugar cane crusher to get sugar cane juice. Then the sugar cane juice is boiled in a pan. During the boiling, all the impurities come to the surface which are removed by skimming. While boiling, the sugar cane juice gets concentrated, and after evaporating almost all the water, a pasty crystalline yellow substance is left in the pan which becomes solid after cooling. Whole fruit pulp or extract may be usefully combined with the cultured milk drink. Tropical fruits such as mango, banana, lychee and pineapple may be used. However, temperate climate fruits such as peach, pear, strawberry, apple, cherry and other fruits and berries may also be usefully incorporated. Whole fruits are an excellent source of minerals, vitamins and enzymes. Fruits are a cleansing food. They are easily digested and exert a cleansing effect on the blood and the digestive system. Some fruits are absorbed and processed more slowly into fructose. Their GI rating indicates this. For example, strawberries have a 38 GI and pineapple has a 66 GI rating. The foods with the lower numbers will cause blood sugar to rise then fall more slowly than the foods with higher numbers. However, by not consuming these fruit juices too processed, and allowing pulp and therefore fibre to still be present, and by combining other appropriate foods such as good fats (cultured milk and nuts), the process by which the body processes the sugars in carbohydrates has slowed down. (Carbohydrates/fibre).
The combination of the milk drink according to the present invention provides a surprising texture, taste and aroma that is not predicted from the individual ingredient. It is suspected that there is some interaction in between the raw sugar and the cultured yogurt that provides the appealing flavour and aroma.
The invention will be further described by reference to the following non-limiting Example.
Example milk (4% butter fat) 10Og cultured yogurt
(lactobacillus acidophilus) 25g palm sugar solution
(2Og of unrefined palm sugar dissolved in 12Og of water) 125g sugar cane solution
(2Og of unrefined j aggery dissolved in 12Og of water) 125g strawberry pulp 5Og Bicultured milk was prepared by combining milk and 50% of the cultured yogurt and heating the mixture to 90°C. The mixture was allowed to cool to 430C and then the remainder of the cultured yogurt was added. The mixture was then maintained at 4O0C to 450C for 8 hours. The product formed was of free flowing consistency and did not have a strongly acidic taste. The remaining ingredients were combined with the bicultured milk to produce a strawberry flavoured health drink.
Since modifications within the spirit and scope of the invention may be readily effected by persons skilled in the art, it is to be understood that the invention is not limited to the particular embodiment described, by way of example, hereinabove.
Where the terms "comprise", "comprises", "comprised" or "comprising" are used in this specification, they are to be interpreted as specifying the presence of the stated features, integers, steps or components referred to, but not to preclude the presence or addition of one or more other feature, integer, step, component or group thereof.
