MOISTURE BALANCES

Introduction

Water is a means of transport for cellular nutrients and their waste metabolites, facilitates the transport of CO2 and O2 gases, their quantity, molecular form and their location within the food product, are factors that significantly affect their characteristics specific as appearance, texture, color, etc.

Moisture determination

There are many methods for determining the moisture content of food, varying in its complication according to the three types of water and there is often a poor correlation between the results obtained.

However, the generality of the methods gives reproducible results, if the empirical instructions are followed faithfully and can be satisfactory for practical use.

The methods can be classified as by drying, distillation, by chemical and instrumental methods.

Determination of humidity by direct heating

objective

Determine the moisture present in a food sample by a drying process, in this case, direct heating.

Basis

The stove has the ability to raise the t and keep it constant, in order to eliminate the moisture present in food for a long period of time.

Conclusions

We can conclude that the sample to which the moisture determination was performed contains a moisture percentage of 9.0351%, which is why it is within the parameters indicated.

The climatic humidity conditions that can influence this result must be taken into account.

ACCORDING TO THE OFFICIAL MEXICAN STANDARD NOM-147-SSA1-1996, GOODS AND SERVICES. CEREALS AND ITS PRODUCTS. CEREAL FLOORS, SEEDS OR SEMOLINES. FOOD BASED ON CEREALS, EDIBLE SEEDS, FLOURS, SEEDS OR SEMOLINES OR THEIR MIXTURES. BREADING PRODUCTS. SANITARY AND NUTRIMENTAL PROVISIONS AND SPECIFICATIONS.

A minimum weight is determined by dividing the standard deviation of repeatability (Rstd) of the balance by the required accuracy. In some cases, a safety factor is applied (for example, USP uses 2 x Rstd). To weigh a 50 mg sample, it could be assumed that a device with a readability of 0.1 mg is quite sufficient. Is this correct? Let’s look at an example to find out. If the maximum uncertainty tolerance is 0.1%, and the Rstd value of the balance is 0.1 mg, then the minimum weight would be equal to 2 * 0.1 mg / 0.001 or 200 mg. Therefore, a 0.1 mg device would be insufficient to meet the accuracy requirements established for this example, and a device with a readability of 0.01 mg should be used.

In this case, a semi-micro device, such as the Ohaus Moisture Balances, would be needed to ‘accurately’ weigh the 50 mg samples. In fact, the OHAUS Explorer equilibrium guarantees that samples can be weighed up to 20mg (in real cases, up to 10mg after an appropriate rating),

while maintaining compliance with the minimum weight standards USP41. In addition to their excellent weighing performance, OHAUS Explorer’s semi-micro scales contain features that help ensure maximum weighing accuracy, such as antistatic devices. Static accumulation can be a substantial source of error when weighing small samples. The Explorer series also contains several features that make balances easy to use and suitable for use in regulated environments,

How does acupuncture work? All you need to know

Acupuncture work

Chinese traditional medicine is considered very effective. It consists of many unique methods of treating diseases. Many countries around the world are studying these theories and are beginning to apply them in practice in their clinics. One of these methods is acupuncture. It helps cope with a large list of diseases as well as improve the overall condition of the organism. You can undergo the procedure at a Cross-Up Chiropractic clinic, which employs qualified specialists.

Briefly on the term “acupuncture”

Acupuncture (acupuncture) is an ancient Chinese treatment method. During the procedure, the patient is injected with special needles into the biologically active points. According to Chinese theory, it is believed that the Qi energy is flowing in a person, and only this energy can ensure good health. If it starts to stagnate, various diseases occur. There are over 500 such active points on the human body. They are all connected to each other.

Acupuncture helps:

  • reduce pain;
  • improve the condition of the skin, hair and nails;
  • restore normal hormone synthesis;
  • increase overall immunity;
  • to flush out all the toxins;
  • remove muscle cramps;
  • improve blood circulation.

Acupuncture can really help with a problem with any system of the body.

How does acupuncture work?

A course of acupuncture can only be performed by a specialist who has appropriate training and a license. A person must know when and in what place to insert needles depending on the disease.

The session usually takes place in the comfort of a warm, quiet place on a soft couch. The right amount of needles is injected into a certain part of the body (depending on the problem). The patient usually feels nothing and there is no pain. The session lasts for 15-30 minutes. Then the acupuncturist takes the needles out.

Three to 15 sessions may be needed to improve your health. Everyone feels differently after the treatment. Some feel relaxed and sleepy, others feel a burst of energy.

What can and can’t be done after the procedure?

Immediately after the session, it is recommended that you just lie down for 10-15 minutes and drink water. But these are not all the rules that must be observed. For the duration of the treatment and for two weeks after it, you can’t:

  1. Take any alcoholic beverages. Keep coffee and tea to a minimum. It is better to ask your doctor how much you can drink per day.
  2. Heavy physical activity. Many people feel so energized after the first sessions that they are ready to do something and exercise around the clock. This is not the way to do it. It is better to let the body rest.
  3. Strong drugs like antidepressants, painkillers, and antibiotics are forbidden. Before starting therapy, it is better to ask a specialist about the compatibility of medications and acupuncture.

And the most important point is that for effective results, you need to take a full course of acupuncture. Some patients see an improvement after the second or third time and decide that they have had enough. This is categorically not the way to do it. Only a completed course can benefit the body.
