Bread storing

Another laboratory invoked the role of water in bread staling involving a zipper mechanism that results in the formation of interchain crosslinks 492 Moisture redistribution from crumb to crust played a significant role in crumb firming and amylopectin recrystallization for breads stored for more than seven days 493 According to Piazza and Masi494 to inhibit staling it is more important to slow the dehydration phenomena than it is to increase the initial moisture content in the bread. 

Frozen fish fingers and similar products are made from a mixture of different fish that arrive at the processing plant as frozen blocks of the average size 62.7 x 254 x 482 mm (thick x width x length). The frozen blocks are minced and the still frozen minced fish blocks are mixed and pressed into the desired shape, covered with batter and bread crumbs, baked on the outside (still with a frozen core), packed and stored in a deep freezer. 

What could be simpler than bread Flour, water, salt, and yeast are all you need, right But if you want to ship the bread across the country, store it on shelves for a while, and avoid having it go stale or moldy, you might want to consider getting a little help from some other foods and food products. 

It is worth noticing what other products are likely to share the same aisle or shelf. In a study on how to increase purchases in the Minneapolis and St Paul markets in the USA, by including organic products, a mixed effect on sales was found in upmarket stores, but there was a significant positive effect on sales of dairy products, pasta, bread, cereal and carrots in a discount store (Thompson, 1998). 

Many tribes used the berries as a food supply and included it in their pemmican, a mixture of nuts, meat and dried fruit which served as a suitable food when travelling and hunting. The Iroquois cooked elderberries and served them with com bread. They would sun-dry the berries and store them for winter food supplies. The Meskwaki prepared the berries as a conserve. The wood of the tree was useful in bow making. Straigth stems would be selected and dried, and from this arrows were made. The Iroquois would soak their... 

Pesticides affect the content of microelements and other substances in plants, thus changing their nutritive value, as well as their ability to be stored. This was detected for OCPs in grain and legume harvests. For example, wheat crops treated with some fungicides (zineb, bayleton, and propicanazol) to fight stem rust (Puccirda) produce a lower quality of bread [3]. 

Plastic food wrappers may be printed with pigments that contain lead chromates. Plastic wrappers used for 14 different national brands of bread collected in New Jersey contained a mean concentration of 26 mg of lead for a bag size of 2,000 cm2. A survey of 106 homemakers who buy such breads indicated that 39% of them reused the bags and 16% of the respondents turned the bags inside out to reuse them, suggesting that the potential exists for lead leaching from the paint into the stored food (Weisel et al. 

The bread making properties of ordinary white bread flour improve for some time after manufacture, which is the origin of oxidative flour treatments. The shelf life of such a flour is around a year. If the moisture content can be kept low, either by selecting low moisture wheat or by drying wheat, the shelf life can be increased to three years. This sort of flour is supplied for ship s stores and similar purposes. This is the modern alternative to ship s biscuits. 

The ADD method was used by in-store bakeries and hot bread shops as well as small bakers. At one time approximately 5-10% of all commercially made bread could have been made by the ADD method. 

There is a trade in frozen part-baked breads. Once again it centres around speciality and difficult to make products such as baguettes. The frozen dough is used by hotels and some in-store bakeries. The excess cost of the process can be supported on these products in these circumstances. 

The provisions for spacings are based on the commodity stored, pressure, temperature, and fire protection measures afforded to each tank. Each parameter adjusts the minimum requirements. For large tanks and those containing crude oil, heated oil, slop oil or emulsion breading materials additional spacing requirements should be considered. These include the following ... 

A spectrophotometric assay procedure was used to measure the lipoxygenase isoenzyme activities of fresh and stored soya containing bread improver pastes and powders (77). 

Flour is usually analysed to ascertain if it is genuine and well stored, particularly from the hygienic standpoint, and to determine its commercial value as regards bread making. 

A first approach to analyze such volatiles is the application of the AEDA on extracts prepared by dynamic headspace extraction. An apparatus used for the extraction especially of solid foods is shown in Figure 5 [55]. The powdered material is placed into a rotating cylinder and the volatiles are continuously flushed onto a polymer material (Tenax( )) by using a stream of helium (1 L/min). After 3 hr the volatiles are desorbed from the polymer by elution with a small amount of diethyl ether and evaluated by AEDA after concentration. Since different yields may change the composition of the volatiles during headspace extraction [7], it is essential to sensorially evaluate the flavor of the extracts in comparison with the food flavor itself. The following examples show applications of this method on fresh and stored wheat bread crust [55] and on fresh rye bread crust [P. Schieberle and W. Grosch, unpublished results]. 

On the basis of high FD-factors (Table 3) the sensory significance of 3-methylbutanal and 2-acetyI-l-pyrroIine with malty, roasty odors previously identified as the key odorants in fresh wheat bread crust [21] was established. During storage for 4 days the FD-factors of both odorants decreased significantly, while especially butanoic acid (rancid) and (E)-2-nonenaI remained unchanged. The fatty, green note of the latter odorant especially contributes to the stale note detectable in the overall crust flavor of the stored wheat bread. 

In Marin, I pay someone to bake my bread I can certainly ask the store to remove the worm so I don t have to do it. Anne replies. 

Figure 8.16 Effect of moisture content on retrogradation kinetics of starch in starch gels or bread 1 wheat starch gels stored at 4°C for 14 days 175 2, 3 and 4 correspond to wheat starch gels, bread and bread with 0.5% monoglyceride, respectively, stored at 25°C for seven days.178...

Although detailed statistics are not available, the main product areas in organic baking in the UK, by volume, are in-store bakery bread, mainstream sliced bread, speciality breads, and cakes, biscuits and other products. 

Organic bread sold through in-store bakeries within supermarkets is rarely if ever produced on the premises. When the EU Regulation became law in 1991 the multiples opted not to seek certification for scratch baking in their in-store bakeries. Although justified at the time on grounds of cost - 300 to license a production unit - the more likely reason (apart... 

Well known in the supermarkets and health food stores, Country Life Bakery began focusing on wholemeal and sourdough and in the last 9 years has increasingly turned its attention to organic to satisfy customer demand. Its breads are sent interstate now and to Southeast Asia, mainly Singapore.
