Journal of Ethnic Foods volume 6, Article number: 32 (2019)
Paruthi Paal is a very nutritious drink that is very much popular in the Tamil Nadu state of India. Paruthi Paal is regarded as “triple-nutrient” as it is a very rich source of protein, essential fatty acids, and sugars and can be called as an energy drink. The present paper will be focussed on developing a process protocol for the preparation of the nutrient-rich product “Paruthi Paal” from the traditional knowledge available. The paper also focusses on typical ingredients required for making this healthy drink. Further, this paper will present various health benefits of cottonseed which includes healing of stomach ulcer, regulation of menstrual cycle, curing cold and cough, maintaining blood pressure and also acting as an antioxidant. Overall, the study leads to a development of a protocol and a traditional delicious product (Paruthi Paal) with a view to popularise among other parts of the globe.
Cotton is mainly cultivated as a fibre crop which is considered as the main economical part. After the removal of fibre after ginning, the seed cotton was left with the most important by-product cottonseed. Cottonseed oil (20–22%) contains unsaturated fatty acids and considered as a healthy oil. It is used for frying, salad dressing and also blending with other oils such as soybean, groundnut and sunflower oil to improve their quality with respect to flavour stability. Apart from healthy oil, cottonseed also contains a good quantity of protein (20–25%) with some phenolic compounds which impart antioxidant property to protein component. These essential components of cottonseed can be utilised as a source of nutrition in cotton-growing countries. Tanzania, Uganda, Zimbabwe, Burkina Faso, Zambia, and other ten countries of African subcontinent depend on cotton earnings and its crucial source of income for farmers and their families. These countries also face menace of malnutrition and energy malnutrition. Hence, cottonseed, if utilised as a food supplement, can play a crucial role to overcome these problems in a cost-effective manner.
This paper will give insights on ethnic food which is traditionally a speciality of “Tamil Nadu” state of India (Fig. 1). This delicious drink is popularly known as Paruthi Paal (Paruthi means cottonseed and Paal means milk). Paruthi Paal is regarded as “triple-nutrient” as it is a very rich source of protein, essential fatty acids and sugars and can be called as an energy drink. The history of consumption cottonseed as a source of energy or Paruthi Paal is not so rich. However, at the time of World War II due to the unavailability of most of the other edible sources, various products made from the cottonseed were served to the soldiers . This started the use of the cottonseed consumption in the modern era. This article will explain the detailed protocol for the preparation of Paruthi Paal and also about its beneficial effects. These beneficial effects are mainly discussed based on the traditional knowledge of local people. The gossypol, a toxic phenolic compound having anti-nutritive value present in the cottonseeds, must be removed to make cottonseed milk fit for human consumption. So, it is preferred to use glandless seed which do not have the risk of gossypol.
For extraction of milk, cottonseeds need to be washed and then soaked in water for overnight. After soaking, seeds were blended with the help of a blender or mixer, and later on, the blended material is kept on a muslin cloth and the filtrate is collected in a jar. The proximate analysis of cottonseed reported to have 23.1 g of protein, 22.9 g fat, 43.2 g carbohydrates, 7.3 g moisture and 3.5 g of minerals per 100 g of cottonseed . After popularisation of beneficial effects of cottonseed milk, various edible products have been developed indigenously by localites of Tamil Nadu state. These food products include tamucurd, cheese, curd, yogurt, ice-creams, sausage type meet, cottonseed soup (Nigeria), chocolates, biryani and paruthi halwa. Paruthi Paal is the best remedy for cold and cough; it cools the body and very good for the nursing mother. Also, it is a very good alternative for cow’s milk so it can be had by people having lactose intolerance. Many districts in Tamil Nadu serve Paruthi Paal as a welcome drink to their guests. It is believed to have high density cholesterol (good cholesterol) and flush out low density lipoprotein (bad cholesterol), reduce the risk of cardiovascular diseases, improve the neurological health, reduce body heat, ensure good functioning of pancreas, improve blood circulation and digestion and also report to induce good sleep. Jaggery is usually added for sweetness. Cottonseed milk can be a nutritious innovative drink with added jaggery or 2% sucrose solution and 0.2% of common salt. The addition of sucrose and jaggery further improves the taste of cottonseed milk. Strawberry or sitaphal pulp is also added in cottonseed milk for enhancing its taste, flavour and consistency. The heating of cottonseed milk at 70–80 °C for 10–15 min will lead to its pasteurisation. It is also a very good alternative to cow or buffalo milk with respect to acidity, viscosity and total solid content. The physicochemical property and sensory characteristics are acceptable and comparable with the commercial powdered cow’s milk . The total solid content in cottonseed milk ranges from 11.8% to 13%, acidity varies from 0.17% to 0.19% (lactic acid g/100 ml), pH ranges from 6.5 to 7.1 and viscosity from 2.8 to 3.4 cP . Recently, cottonseed milk has also been used in the cosmetic industry for making moisturising lotions, shampoos, conditioners, skin creams, herbal medicine, etc., and these products are available commercially in the market . Cottonseed milk is very famous in Madurai (Tamil Nadu). The milk extracted from the cottonseed is the main ingredient for Paruthi Paal. In the next section, we will see the detailed process of “Paruthi Paal” preparation.
Protocol for preparation Paruthi Paal
Ingredients (servings, 8–10)
Ingredients include cottonseeds (Paruthi) (one tumbler (glass)), rice/kudu millet (one-fourth tumbler (glass)), jaggery (one tumbler (glass)), cardamom powder (one-fourth tsp), coconut milk (one tumbler (glass)), grated coconut (one-half tsp)/coconut milk and dry ginger powder (one-fourth tsp) (Fig. 2).
Soak the cottonseeds overnight and wash them in running water by picking out the cotton and mud sticking to them. Continue cleaning in running water for 3 to 4 times. Extract milk from cottonseeds by adding a little water to it and blending in the blender for a minute. Strain the milk from it using a muslin cloth or strainer. Then again, pour a cup of water and blend it again and filter the milk from cottonseed mash (Fig. 3). Similarly, extract milk from the coconut milk (Fig. 4c) and make jaggary syrup. Syrup can be made by crushing the jaggery and take it in a pan with water (to dissolve the jaggery), keep in medium flame, until it comes to syrup consistency (Fig. 5). Filter it and keep it aside.
Pour the filtered cottonseeds milk in a pot and start heating it, stir once in a while, until it starts boiling. Keep in low flame for 5 min, once it starts boiling and keep on stirring. Take rice flour in a cup or kodu millet flour, pour in a cup of water and stir it well, so that no lumps are formed or make a paste with almonds as shown in Fig. 4a, b. Now pour this to the boiling cottonseed milk and continue stirring, or else lumps would be formed. Crush the cardamom pods and keep it aside. Add in cardamom powder, cardamom pods, ginger powder and continue stirring, until it thickens. Pour in the jaggery syrup, keep in medium flame for 5 min and keep on stirring every now and then until it thickens.

Paruthi Paal contains cottonseed milk as a main ingredient which is a rich source of protein, good fat and fibres. The study also developed a process of cottonseed milk preparation. The developed ready-to-serve product “Paruthi Paal” can also serve as a protein supplement for the prevention of malnutrition. Cottonseed milk is indeed a novel product that can be commercialised in India. Apart from health supplement, Paruthi Paal has several other beneficial effects such as acting as an antioxidant, prevents from heart-related problems, prevents stomach ulcers and many more.
