Mustasa or Mustard leaves are eaten in the Philippines as a green leafy vegetable, either fresh or pickled in brine. They are excellent sources of essential nutrients.
1. Gather good quality leaves. Fresh leaves are preferred. Some folks like leaves with flowers.
2. Wash and rinse thoroughly.
3. Wilt under the sun for two hours.
4. Arrange leaves in earthen jar and sprinkle 1/4 cup salt for every kg of mustard leaves.
5. Pour 3 cups of rice washing.
6. Allow natural fermentation of lactic acid bacteria for seven days.
7. Fermented mustard should be sour and crispy.
If you plan to make burong mustasa on a regular basis, monitor and adjust salt concentration using salometer.

1. Selected heads of cabbage are core-shredded and soaked in tap water with 2.5% (by weight) salt concentration and allowed to ferment. During the initial stages of fermentation, there is a rapid evolution of gas caused by Leuconostoc mesenteroides; this process imparts much of the pleasant flavour to the product.
2.The next stage involves Lactobacillus cucumeris fermentation, resulting in an increase of lactic acid;
3. Finally after approximately 5 days at 20-24°C, the third stage, involving a further group of lactic acid bacteria such as Leuconostoc pentoaceticus, which yields more lactic acid combined with acetic acid, ethyl alcohol, carbon dioxide, and mannitol.
4. The fermentation process ends when the lactic acid production is approximately 1-2%. This can be tested by titration of the acid with a 0.1 N sodium hydroxide (NaOH) solution, using phenolphthalein (0.1% w/v) as colour indicator (i.e., 2-5 drops are added to the acid solution; colour will change from clear to pink and persists for 30 seconds). After the fermentation process, either the tank is sealed to exclude air or the product is then packed into glass jars or canned.
1. Select good, mature cabbages; remove external leaves; wash remaining heads well. 2. With a sharp knife cut the heads into four sections, removing the hearts. Slice two and a half kilos of cabbage into fine strips approximately 2 to 3 cm long. 3. Put above cabbage in pot or plastic container and mix well, adding two tablespoons of salt. Let stand for 15 minutes or more, while preparing another batch of cabbage. The quantity of salt added must be in accordance with the amount of cabbage used for proper fermentation. While the cabbage is in repose, the salt works to reduce the lot size, extract the juice, and soften the cabbage. This will prevent breakage of strips during packaging. 4. The cabbage is packed into clean wide-mouth 4 L glass or plastic jars. 5. Eliminate air bubbles from the cabbage by pressing hard with hand. This allows juices to penetrate the tissues and holes formed between strips. Soft pressing is recommended to avoid breaking the finer strips. 6. Place plastic bag full of water on top of the cabbage to prevent air from penetrating the container and the cabbage. Close the jars tightly. After approximately 24 hours of fermentation, the juices should have completely covered the cabbage. Otherwise, add a brine solution composed of 25 g of salt per L of water until all cabbage strips are covered. The presence of bubbles is an indication that fermentation is in progress. This process lasts from 5 to 6 weeks or until the bubbles disappear from the solution, after which the fermented cabbage is heated in a pot until boiling. 7. Pack cabbage into sterile jars and cover with hot juice, leaving a head space of 2.5 cm below the jar’s rim. 8. Place lids on each jar and sterilize the jars in a boiling water bath for 15 and 20 minutes for 0.5 L and 1 L jars, respectively.

With the advent of fastfoods around the corners and tempting food advertisements nowadays, local rootcrops such as camote, cassava and tugi, and legumes such as peanuts and green peas are not so much considered for snack. There are more reasons why we should think otherwise.
Root crops are rich in carbohydrates, our cheap and main source of energy. Legumes, on the other hand, are good substitutes for meat as protein source. But aside from being carbohydrate and protein sources, respectively, root crops and legumes can also be considered as functional foods. They have other nutritional and health benefits. They are both good sources of dietary fiber, a food component which has been associated with the prevention of several chronic diseases such as cardiovascular diseases, colon cancer, and control of diabetes.
A recent study done by the Food and Nutrition Research Institute of the Department of Science and Technology (FNRI-DOST) determined the effects of local root crops and legumes in lowering cholesterol levels among humans with moderately-raised cholesterol levels. Five rootcrops and six legumes were studied. The subjects were given 50 grams available carbohydrates from the test foods for 14 days and venous blood samples were collected for analysis of total cholesterol, triglyceride, and HDL/LDL cholesterol. The study showed that camote and cassava have significantly decreased the total cholesterol levels of the subjects. This is also true for legumes like peanut, abitsuelas, green peas, mungbean, pigeon pea, and chick pea, with peanut showing marked decrease in total cholesterol levels among the subjects.
The study also showed that cassava, abitsuelas and peanut have significantly decreased low density lipoprotein cholesterol (LDL-c) levels of the subjects while camote, tugi and mungbean significantly decreased triglyceride levels. The study concluded that root crops and legumes may have a significant role in reducing lipid biomarkers like total cholesterol, LDL-cholesterol and triglyceride due to their high total dietary fiber content.
How does dietary fiber lower blood cholesterol? Cholesterol is the main component of bile acids secreted during digestion in the intestine. Dietary fiber coats the bile acids in the intestine and excreted in the body. The body then draws cholesterol from the blood to form bile acids, thus, lowering blood cholesterol level.
Messages 4 and 5 of the Nutritional Guidelines for Filipinos developed by the Technical Working Group led by the FNRI-DOST suggests consuming root crops and legumes. So why don’t we try eating boiled camote or peanuts the next time we have our snack?
