为了开发柑橘全果产品,降低全果原浆粒径,改善其流变特性,对柑橘全果粗浆进行球磨处理。以赣南脐橙为原料,经粗粉碎后球磨处理不同时间(0、30、60、90、120、150、180 min),得到不同粒径的全果原浆,研究经球磨处理后赣南脐橙全果原浆的粒径和流变特性的变化。结果表明,球磨处理能有效降低全果原浆的粒径,球磨处理180 min后果浆平均粒径由110.00 μm下降到56.53 μm,整体下降了49%。随着球磨处理时间的延长,全果原浆越来越均匀细腻,且无团聚现象。球磨处理的赣南脐橙全果原浆体系随剪切速率的上升,剪切应力增大,而表观黏稠度下降,出现剪切稀化现象,是一种典型的假塑性流体,具有较好的黏弹性。与未经球磨处理的原浆相比,球磨处理60 min得到的赣南脐橙全果原浆黏稠度最高,凝胶状态最为稳定,适合加工为果酱类黏稠度较高的产品;而球磨处理30 min得到的原浆体系黏稠度最低,但流动性最佳,适合加工为果汁类流动性较好的产品。本实验为柑橘全果产品加工提供了参考依据。 相似文献

This study evaluated the physicochemical characteristics and volatile profile of strawberry pulp subjected to factors, pasteurization (unpasteurized and pasteurized), freezing method (static air and forced air), and their interactions, during 12 months. Strawberry fruit were washed, sanitized, and pulped. The pulp was packaged, pasteurized, and frozen (0, 2, 4, 6, and 12 months). We concluded that pasteurization alters the strawberry pulp color. The impact of pasteurization and freezing method on the strawberry pulp pH, titratable acidity, and soluble solids variables is negligible. We tentatively identified 13 volatile compounds in fresh fruit and pulp, ethyl acetate, ethyl hexanoate, and linalool being the volatiles with the highest area percentage in the two products. The esters were predominant in both the fruit and strawberry pulp. Time is the most determining factor in modifying the strawberry pulp volatile profile, having an isolated effect on the increase of ethanol, ethyl butanoate, and linalool.
Practical applications
The strawberry is very used worldwide as raw material to different products, due to its color, flavor, and aroma. Thus, obtaining further information about the changes caused by processing and storage is of great importance for the food industry. This study shows the effect of simultaneous application of different processing techniques (pasteurization and freezing methods) on physicochemical variables and volatile profile of strawberry pulp over prolonged storage. Significant and unpublished results involving color, pH, acidity, soluble solids, and volatile compounds of strawberry frozen pulp over storage period are presented and may be applied for food industry to keep the pulp quality. 相似文献16.

The Black plum (Vitex doniana) fruit was studied in respect of the chemical composition of its edible pulp, and syrup produced by concentration of extracted juice. Organoleptic evaluation was also conducted on the developed syrup. The results show that the edible pulp of the fruit is acidic (PH 5.20), high in moisture (67.9%), sucrose (12.5%) and reducing sugar (7.3%), and fairly rich in vitamin C (28.5 mg/100 g). Temperature of water used for extracting juice from the pulp correlated positively with soluble solids (r=0.86), titratable acidity (r=0.91) and negatively with vitamin C (r=?0.61). The syrup contained higher reducing sugars (51.7%), lower moisture (25.0%), but similar sucrose (12.9%) content compared to the pulp. The soluble solids of the extracted juice and consequently the yield of the syrup varied with water temperature. An optimum temperature of 80°C gave 20% (w/w) syrup per pulp. The syrup compares favorably with sucrose in sensory properties in model foods. 相似文献

The edible pulp of Musa ‘Bhimkol’ was analysed for certain organic compounds and mineral nutrients at two stages of development of the fruit to evaluate it as a baby food. Energy value and carbohydrate concentration increased substantially as the fruit ripened so that 16.8% of the energy requirement (recommended daily allowance, RDA) for six-month-old infants would be met by 100 g of the fresh pulp. Although vitamin C content decreased at maturation, 7% of the RDA would be provided by 100 g fresh pulp. The fruit was found to be very rich in macro- and micronutrients, and 100% of the six-month infants RDA for K, Mn, Zn and Se would be satisfied with 100 g of fresh pulp. This amount of pulp would also provide 86%, 57%, 24% and 12% respectively of the Mg, Cu, Fe and P RDA. P and Mg were found to be more highly concentrated in the ripe than in the unripe fruit whereas the reverse was the case for Ca and Se. Aspartic acid, glutamic acid and leucine were the major amino acids in the ripe fruit and respectively constituted 13.1, 12.5 and 7.9%, of the total. The concentration of essential and non-essential amino acids was much higher than that in a commercial banana. Twelve of the 17 amino acids analysed were more concentrated in the mature compared with the green fruit, and 11 of these were an order of magnitude higher than in M paradisiaca L banana. The results of the present study demonstrate that Musa ‘Bhimkol’ is a nutritious baby food. 相似文献
