A process for preparing a soybean protein material having a red color which when combined with uncured meat makes a product having a uniform red color in the raw state and which when cooked has a uniform grey-brown color similar to cooked natural meat. This combined product is prepared by treating the soy protein material with a combination of the colorants betanin and canthaxanthin. The disclosure is directed to the special colored soy protein product, and also its combination with uncured meats.

A product of fish meat paste simulating the meat of the lobster containing a heat-coagulated mixture of one part by weight of fish meat paste and 0.2 to 2 parts by weight of mannan gel modified by freezing. The fish meat paste is made of "surimi" and at least one additive selected from salt, seasoning agents, starch and texturing agents. The modified mannan gel is in the form of flakes less than 3 mm thick to impart to the coagulated mixture a texture which gives a particular oral sensation as if real lobster meat were being eaten.

Pigment compositions useful for supplementing marine animal feeds comprise comminuted Haematococcus cells treated to degradation of carotenoids, typically by coating or by combination with an anti-oxidant. Encysted Haematococcus cells are ground at cryogenic temperatures, typically by combining the cells with liquid nitrogen in a suitable impact mill. The resulting powder has an average particle size below about 5 .mu.m. Usually, the Haematococcus will be grown in large-scale culture ponds under controlled conditions.

The present invention has several plausible embodiments. In one embodiment an apparatus for coating a medical device is provided. This apparatus includes a coating chamber, a vibrating structure within the coating chamber the vibrating structure capable of suspending a medical device positioned in the coating chamber, and a coating source, the coating source positioned to introduce coating into the coating chamber. In another embodiment a method of coating a medical device is provided. This method includes moving a medical device into a predetermined coating area, vibrating a structure below the medical device, the vibration of the structure forcing the medical device away from the vibrating structure, and coating at least a portion of the medical device that has moved away from the vibrating structure.
