Fruit pulp

Preserves and fruit juices Much use is made of sulphur dioxide to preserve fruit pulps and juices, and for these applications molybdenum-bearing steels should be specified. 

After ingestion of cactus pear fruit pulp, both betanin and indicaxanthin were found in human plasma (with AUCo i2 h values of 0.46 and 29.2 lunol/hr/mL, respectively), partly associated with LDL, and in urine (3 and 76%, respectively, of the ingested compounds)," indicating that indicaxanthin was better absorbed than betanin. The bioavailability of indicaxanthin from prickly pear fruit pulp was 20 times that of betanin, suggesting differences in the fates of the two classes of betalains (betacyanin and betaxanthins) in the human body. In rats, betanin appeared to be...

Cactus pear, previously known as prickly pear, has been mainly studied for its green fleshed pads known as nopalitos. It originates from Mexico but is cultivated in Chile and Peru, mainly for cochineal production, and also in the U.S. (California and Texas), South Africa, India, Israel, and the Mediterranean, amounting to a total of 100,000 hectares under cultivation. The cactus pear fruit is a berry with many seeds and a mean weight of 160 g. Its fruit pulp covers a color range from deep purple to green. " ...

Figure 2.3 illustrates a process in which the outer layer of a product is quickly frozen as a congealed crust. These CRUSToFREEZE plants have a capacity between 1500 and 5000 kg/h and require 0.5 to 0.8 kg LN2 pro kg of product, which has to be frozen totally on a conveyor belt. Figure 2.4 shows the product exit of the plant in Fig. 2.3. The freeze drying of coffee and tea extracts, fruit pulps or small pieces of meat require a multi- stage pretreatment. The granulated end product from coffee and tea extracts should have a defined grain size, a desired color, and a predetermined density. Fruit pulps should become granulated, with the appearance of fruit pieces, while meat pieces should not stick together like a small meat ball, but be recognized as single pieces when presented in a meal.

Fragments of plant raw materials (e.g., grape skins or fruit pulp) can in some cases pass through a process and enter the final product. If this occurs due to a processing problem, it is generally transitory and can be addressed by refiltering the product. 

In some countries, it is common practice to add sucrose to the milk for yoghurt, to reduce the acid taste. It is also very common practice to add fruit pulp, fruit essence or other flavouring, e.g. chocolate, to yoghurt, either to the milk (set yoghurt) or to the yoghurt after fermentation (stirred yoghurt).

Such slurries comprised mixes of 50—70% of nitrates, perchlorates or chlorates of NH3 and alkali- or alk-earth metals, 25—30% of sensitizing expls, such as... 

From a number of pilot applications Fig. 1.4-8 shows the quasi-continuous train for the sterilization of fruit juices with pulp contents. The high pressure sterilization offers valuable advantages with respect to the quality of the final product compared to other sterilization procedures, especially if natural fractions of fruit pulp are desired by the consumers.

Another contentious issue is the further processing of fruit pulp, and especially citrus pulp. The addition of water to such a pulp can give an extract containing around 5% solids, which can be concentrated to around 65% and used to dilute (more expensive) pure juice. These products are normally described as... 

Jams or fruit preserves result from the boiling of fruit pulp with saccharose and often with glucose as well. Similar products are fruit jellies obtained from fruit juice instead of pulp and fruit syrups, made by mixing fruit juice with sugar syrup without boiling. With such materials the following determinations and tests are made. 

Since this lack of uniformity exists, it would seem wise to explore whether or not 2 mm. of penetration is essential. If the energy level is low, then the fruit pulp will not be penetrated at the poles, and uniformity of dose over the whole outer jacket will be an appropriate objective. On the contrary, it may be desirable to orient the fruits preferentially so that the dose reduces slightly from the equator towards each pole this may be difficult to achieve. 

Of biochemical interest is the presence of quite significant amounts (up to 5%) of the iridoid glycoside loganin (see page 188) in the fruit pulp of Strychnos nux-vomica. This compound is, of course, an intermediate in the biosynthesis of strychnine and other terpenoid indole alkaloids.

The texture of fruit pulp or tomato paste can be achieved in nonstandardized products, such as pizza sauces, through the introduction of texturizer starches. These are typically highly crosslinked starches that are subsequently drum dried. 

A method is described for mixing fruit pulp with prepared Jerusalem artichoke tubers. 

The innovative method involves many stages, including grinding and mixing Jerusalem artichoke with fruit pulp. The mixture is homogenized, heated, and packed in sterilized cans.
