Color is an important factor in evaluating the quality of meat products. Adding the food color fixatives to meat products, which can optimize their appearance and improve their quality. In traditional meat products, nitrite is usually added as a coloring fixative, which will seriously threaten human health. Nowadays, food coloring substitutes are the popular development direction of coloring fixatives for meat products.

Types of food coloring agents, Natural: as Orange yellow beta carotene from green plants, red color from red beet juice and red oleoresin from paprika. Synthetic as Carmines, and Carmoisine. 

Foremost thing in podiatric care is a podiatric chair which serves many purposes ranging from clinical examination to dressing to many procedures but it is quite expansive and very few physicians, at least in developing countries, can afford it. So, we designed a very economical and affordable improvised device which serves effectively as a substitute for a podiatric chair.

The vast majority of people with diabetes, around 80 %, living in developing countries, shall face the largest increases in the burden of diabetes over the coming decades [1]. Diabetic foot problems are a major cause of morbidity and premature mortality in people with diabetes and contribute substantially to the health care costs associated with diabetes [2,3,4]. Foot problems are a threat to every person with diabetes. Worldwide, more than a million lower leg amputations are performed each year as a consequence of diabetes. Approximately 3–4% of all people with diabetes have a foot problem. In some developing countries, foot problems may account for up to 40% of available resources [5]. Diabetic foot care is one of the most ignored aspects of diabetes care in developing countries such as India [6.7]. Good foot care includes physicians, specially trained in Podiatry and paramedic staff, besides some gadgets, including special podiatric chair.

Practicing Podiatry in some developing country like India, is a difficult task since infrastructure is missing and many gadgets are unaffordable. Most physicians cannot afford a podiatric chair since it costs thousands of dollars and even a few who can afford it do not see any proportionate return out of it. I saw proper podiatric chair, for the first time, in King’s Hospital, London in 2003 when I happen to meet Prof. Mike Edmonds.

When I returned to India, I had a peculiar zest to create some improvised version of the chair. Then the team of physicians in LK Diabetes Centre designed an improvised foot stand, which delivers most features of a podiatric chair [Figure.1].

Figure 1: Proper Podiatric Chair

Parts of Foot Stand:

1.Base of Foot Stand: The stand has a solid heavy wooden base to support weight of the foot and leg.

2.Column: Flat broad column establishes connection between leg rest and base.

3.Leg rest: It is a cut in the column on the top with padding where a patient accommodates his ankle.

4.Pocket: The column has a pocket to accommodate necessary equipment e.g., Monofilament, Wartenberg wheal, Tuning fork, Hammer, Thermo tip, measuring tape, caliper for 2-point discrimination, cotton wool etc. Nail care related instruments can also be placed in the same pocket e.g., calipers and files. The same pocket can accommodate dressing related material too during management of a foot ulcer or lesion.

Utility Of Foot Stand:

1.It serves as a good working foot examination platform [Fig.2].

Figure 6: Peripheral Pulse examination

When an observer is sitting in his chair, he has to lean a little to examine the foot in detail. He can undertake neurological examination using a tuning fork and Monofilament. Even peripheral pulses can be easily examined. The examiner can keep all necessary gadgets in the pocket of the foot stand. Range of foot joint can be assessed to diagnose limited joint mobility (LJM). Skin temperature and deformities of foot can also be checked. Even Audio Doppler can be accommodated in the pocket and Ankle Brachial Index (ABI) can be calculated [Figure.7].
