Abstract

The formulations of Moringa porridge were prepared by the assortment of peanut, wheat flour, gram daal and sugar. The formulations were formed by changing the quantity and processing conditions of the ingredients. Chemical, vitamin and mineral analysis were carried out. Similarly, the leaves and stalks from Lahore were used as green tea. The nutritional analysis as well as polyphenols was anticipated. The approximate values of protein, fat, fiber, moisture, ash, carbohydrate, and energy of the leaves were 15.5%, 11.04%, 12%, 10.418%, 11.40% 37.48%, 319.92 kcal respectively. The polyphenols for the leaves and stalk were 10.95µg and 20.02µg respectively. Vitamin A and C were 12.80mg and 232mg for the leaves respectively. Minerals like Ca, K, Zn, and Fe were 205mg, 242.52mg, 16.10 mg, 16.25mg for Lahori leaves, and 20mg, 155mg, 5.88mg, 10.595mg for Lahori leaves formulations developed correspondingly. The porridge and tea made from M. olifera leaves and stalk were essential and valuable with respect to health and medicinal point of view.

Introduction

Plants are very important for the mankind’s health, welfare and for the immunity of the body from the beginning of life. Many herbs are present in Pakistan’s environment which is very useful but usually ignored by the people. As an alternative these herbs are the best for the treatment of lethal diseases. As many herbs are used for health in Asia and Africa. Whereas the world’s famous herbal treatment happened in India. Some herbs are edible, some are poisonous, and some become edible after followed by some processes. Some herbs have their fruits which are edible but leaves stem and bark is bitter in taste, but they may be nutritional as well. 

The poverty rate in the Asia is becoming very high, under nourishment and mal nourishment as well. The 21st century which is also known as the century of biology as many technologies like biotechnology, bioinformatics, and herbal technology are becoming very imperative for the welfare and the prosperity of people. Mostly these disciplines work for the comfort of the human being. Considering the poverty level and the nutritional loss of the people, science always tried to help to triumph over both poverty and nutritional loss. These deficiencies can be recovered by the herbs that are unnoticed. Moringa variety is one of the herbs that help to accomplish these deficiencies.1

Moringa olifera is the valuable nutritional plant. This plant contains the high value of minerals and vitamins and other very significant nutrients so it becomes the important medicinal plant.2 In different countries it is known by different names as there are more than 400 names for this plant in different languages such as in Bangaladash it is said to as Sajina, Sajna (bangali language), in united states it is known as Horseradish tree, drumstick tree (in English language) , in India Moringa is called as Sahingan, Mungna (in hindi language), in Malaysia it is said as Murinna, Muringa, Tishnagandha (in Malyalam language);in northern region of India Sevaga, Segata (Marathi language);in Punjab region people used to say Moringa as Sohanjana (Punjabi language);Sobhanjana, Sigru, Murungi, Dvishiguru (Sanskrit language) and Sehjan (Urdu language) Moringa’s names in varied Indian languages and regions, well in Pakistan Moringa is known as Sawanjana, Bangladesh, Sri Lanka, tropical Africa, Arabia, Philippines, Cambodia and Central, North and South America also use different names for Moringa olifera.3

The scientific classifications for Moringa olifera are Kingdom Plantae, Order Brassicales, Family Morinacea, Genus Moringa, Species olifera.4 The plant Moringa is found all over the world as it can grow in a dry or simple environment.5 Moringa olifera is the most widely cultivated specie all around the world. Different countries contain different species of Moringa plant. There are different species of Moringa such as, arborea, borziana, longituba, rivae, stenopetala, pygmaea, ruspoliana, drouhardii, hildebrandtii, ovalifolia, concanensis, oleifera, peregrine.6 oleifera, peregrina, stenopetalaand drouhardii are the species of Moringa which are rich in nutrition and used to fulfill nutritional deficiencies.7

The plant grows rapidly under favorable conditions. It can also grow in very dry region, if watering then it can grow bigger and faster. World Health Organization (WHO) researched on Moringa olifera plant and they believed that Moringa olifera is rich in nutritional and medicinal values. Extract of Moringa has pharmaceutical properties. Different parts of Moringa olifera such as the leaves , root, seed, bark, fruit, flower, immature pods are used for the treatment of different diseases,like these are used for the treatment of cardiac and stimulants for the circulatory system, used against the tumor formation, pyretic, pasmodic, bacterial, fungal, diabetic and pileptic activity, against inflammation, ulcer, hypertensive and lowering the level of cholesterol, and also for the treatment of different ailments in the indigenous medicinal system. It is also used for the treatment of anemia, arthritis and other joint pain, asthma, cancer, constipation, diarrhea, epilepsy, stomach pain, intestinal ulcers and spasms, headache, heart problems, kidney stones, fluid retention, thyroid disorders, parasitic and viral infections.2

Moringa olifera is also used for ornamental, curative and industrial uses. All the parts of this plant are edible and contains the important minerals (potassium, iron, calcium, sulphur, selenium, zinc, magnesium, phosphorus, copper), amino acids (9 essential amino acids (Histidine, Isoleucine, Leucine, Phenylalanine, Methionine, Lysine, Valine, Tryptophan, Threonine) proteins, vitamins{vitamin B1, vitamin B2, vitamin B3, vitamin A (Beta-carotene), vitamin C, vitamin E and choline}, Zeatin, quercetin, sitosterol, caffeoylquinic acid and kaempferol and various phenolics.2

All parts of the plant Moringa olifera has great importance, full of nutrition that’s why it is known as “Miracle Tree”. The roots, leaves, flowers, buds, pods and the juice of roots, buds, and flowers have great importance for the medicinal uses.3

Moringa olifera is best nutritional food for the breasts feeding and pregnant women because during these stages the most probable chance of nutritional deficiency. But one thing should remind that the excess of anything is bad. It is likely unsafe for pregnant women to use bark, root, and flower of Moringa because the chemicals present in the bark, root and flower can make the uterus contract that further cause the miscarriage. Moringa is also used after delivery to increase the breast milk production. Moringa leaves and pods powder is best known for the treatment of mal nutrition and under nutrition. The main reason of mal nutrition starts from the birth; the deficiencies occur during pregnancy and after birth could not be recovered throughout the child’s and mother’s life. So the Moringa leaves powder help to overcome these deficiencies. Because of this wonderful ability, Moringa is known as “Mother’s Best Friend”.7

Material and methods

For the preparation of tea and porridge the stalks and leaves from nursery were collected and washed with deionized water then allowed to put into 1% saline solution for 5 minutes. Then dried at room shade for 3 days, and on 4th day put these in the sunlight for 30 minutes. The dried stalks and leaves were crushed properly. The crushed stalks and leaves infusions were used to prepare green tea and porridge formulations for sensory evaluation (Table 1).

Mineral profile

The samples were subject to mineral assay through wet digestion considering the protocols of AOAC (2016).8 For the estimation of Calcium and potassium, Flame Photometer-410 (Sherwood Scientific Ltd., Cambridge, UK) will be used whilst iron and Zinc measured through Atomic Absorption Spectrophotometer (Varian AA240, Victoria Australia).

Vitamin A & C contents

Vitamin A & C was measured spectrophotometrically by following the method described by Karnjanawipagul et al. 20109 and Raghu et al., 200710 respectively.

Total phenolic contents:

Total phenolic content determination was performed for samples by using procedures described by Singleton et al.(1999). Total phenolic content was calculated and expressed as Gallic Acid Equivalent (mg Gallic Acid/100g).

Results and discussions

Results of this study revealed that Moringa olifera is not only enriched with essential macro nutrients (Protein, fiber and carbohydrates) but also with minerals, vitamins and polyphenols. 

The moisture for Lahori Moringa leaves, Kashmiri Moringa leaves and Lahori Moringa stalks were 10.41%, 6.79% and 1.08% similarly ash content for Lahori Moringa leaves, Kashmiri Moringa leaves and Lahori Moringa stalks were 11.40%, 20.15% and 12.00% respecively which showed similarity to the results of Jongrungruangchok et al.,(2010)11 that were in the range of 8.52%-13.53% for moisture content and 6.39%-7.99% for ash content. As the less moisture content helped in the long preservation of edible things and the ash content determine the mineral contents. 

The leaves of the Moringa olifera were observed for protein which showed 18.40%, 15.90% and 9.60% of Lahori Moringa leaves, Kashmiri Moringa leaves and Lahori Moringa stalks respectively. These results are to some extent similar to the results of Joshi and Mehta et al.,(2010)12 which showed the protein contents in range of 23.42%-23.78%. This difference may be depends upon variety, land conditioning and climate. Protein content also comparable with pulses protein as Moringa is affordable for community of developing countries like Pakistan, because in a study by Shaheen et al., (2012)13 protein contents of whole mash beans lies in range of 21%-30%. So, ultimately the Moringa is cheap source of protein rather than pulses.

Analysis of fat showed the range of 11.04%, 6.76% and 2.84% of lahori Moringa leaves, kashmiri Moringa leaves and lahori Moringa stalks respectively. These results looked like with the findings of Foidl et al., (2001).14 In which fat contents showed to be 5.2%-6.5%. The fiber estimation of Lahori Moringa leaves, Kashmiri Moringa leaves and Lahori Moringa stalks showed results 12.00%, 6.00% and 10.20% correspondingly resembled to the work of Joshi and Mehta et al.,(2010).12 In their work the fiber content was 12.10

The results of carbohydrates for Lahori Moringa leaves, Kashmiri Moringa leaves and Lahori Moringa stalks were 36.8%, 44.40% and 64.27% in that order. These values look a lot like to the struggle of Price, et.al., (2007)7 which showed 38.2% for carbohydrates. Whereas the herbs are not well thought-out for carbohydrates source but due to dried form the carbohydrate content compared with cereals and vegetables is higher, which help in better body functioning.

The calories for Lahori Moringa leaves, Kashmiri Moringa leaves and Lahori Moringa stalks were 320.16Kcal/100g, 302.04 Kcal/100g and 321.06 Kcal/100g resembled to the work of Price, et.al., (2007)7 that had worked on it and his results showed 205.00 Kcal/100g calories.

The four different constituted porridge formulations by Lahori Moringa leaves had approximate values ash (5.03%, 2.14%, 1.73%, 2.75%), protein (9.81%, 6.71%, 6.25%, 10.35%) , fat ( 10.83%, 24.45%, 23.68%, 9.5%) and carbohydrates (68.08%, 62.91%, 64.84%, 73.51%) these value correlated to the work of keyetasi, et al., (2009) whose worked was on approximate values of sorgum porridge that were 1.50% ash, 11.7% protein, 1.40% fat, and 85.40% carbohydrates. In the results of Moringa porridge the approximate value for the 4th formulation was comparatively best in respond to the low fat content and high protein values. In accordance to the Moringa variety from Lahore and Kashmir the porridge formulation by Lahori Moringa leaves was comparitivly good but the Kashmiri Moringa leaves porridge was not poor as both have little bit differences in relation to approximate values (Table 3).

Table 3 Proximate values for the porridge formulations of Lahori Moringa

The calorific value of porridge formulations from Lahori Moringa olifera were 409.03kcal, 398.58 kcal, 497.48kcal and 420.94 kcal that was significant to the struggle of Muoki et al., (2012)15 who searched that the complementary food require 356.00 kcal energy. The energy content in the complementary food was less due to the selection of ingredients as the ingredients used by Muoki et al., (2012)15 were less important for the energy consumption whereas the Moringa porridge had the ingredients rich in energy sources that’s why the Moringa leaves porridge had good calorific value.

Mineral estimation of Lahori Moringa leaves and Kashmiri Moringa leaves for iron was 16.25mg and 60.90mg respectively that resembled to the work of Joshi and Mehta et al.,(2010)12 that had results for Iron 24.00mg. The zinc content in the Lahori Moringa leaves and Kashmiri Moringa leaves were 16.10mg and 33.80mg related to the zinc content 13.70mg studied by Foidl et al., (2001).14 The calcium and potassium content in Lahori Moringa leaves and Kashmiri Moringa leaves were 205.00mg and 285.00mg for calcium, 242.50mg and 255.00mg for potasium respectively that resembled to the values calculated by Price, et.al., (2007)7 which were 440.00mg calcium and 259.00mg potassium (Table 4).

The results for the sensory evaluation from the panelists of 15 members the calculated average values showed in Table 8. Sensory evaluation for the Moringa tea was according to six hedonic scales with the reference of Oduro et al., (2014)18 who had evaluated that the taste of tea from Moringa olifera, Hibiscus sabdariffa and Cymbopogon citrates, the taste of Moringa olifera is best according to hedonic scale. On the basis of 50 panelists the 50 % results were in the favour of Moringa olifera and the others two had 30% and 20%.19–21 Similarly this research work had 60% results for tea of Lahori Moringa stalks and 40 % for Lahori Moringa leaves on the source of 15 panelists. The sensory attribute for Moringa green was the best.22,23

Conclusion

Results of current study concluded that 4th formulation is better as compared to others with high opinion to nutritional and sensory evaluation as well as minerals. Similarly the green tea of Moringa stalks is better as compared to Moringa leaves with respect to polyphenols and sensory evaluation. Addition of moringa into local dishes showed the significant increase of the micronutrients level in the fortified formulations. This supplementation could be good sources of Vitamin A & C. it is recommended to use moringa leave in routine local dishes to enhance nutritional status of children and adults.
