Physico-chemical Characteristics as Indicators of Starch Availability from Milled Rice

The hypothesis was tested that certain physico-chemical characteristics might be used as indicators of total starch availability and rate of starch availability of milled rice. Milled unparboiled (uPB) and parboiled (PB) rice samples (n=93) were characterized using standardized methods of physical tests and chemical analyses and anin vitromethod was used for measuring the rate of starch digestion on a subsample of rice (n=26). The rice varieties were dominated by medium long, bold rice grain with high amylose rice and intermediate gelatinization temperature (GT), but a wide range in all characteristics was measured. Small amounts of resistant starch (RS) were measured in the cooked rice, indicating virtually complete starch availability. The RS of PB rice (0·4 g/100 g rice as eaten) was significantly (P<0·004) higher than the RS of uPB rice (0·1 g/100 g) however. The rate of starch digestion was significantly affected by both variety and parboiling. The starch digestion index (SDI) values of the PB samples (mean value 73·7) were significantly (P<0·001) lower than those of the uPB samples (mean value 79·0). The apparent amylose content (AC) was the strongest determinant for SDI in both uPB and PB rice. The widths and shapes of the raw grains and the elongation after cooking were correlated significantly with SDI values for the uPB rice, while the relatively mild parboiling procedure followed in this study eliminated this correlation. The minimum cooking times were correlated significantly with the SDI values in the uPB samples.

农村产业结构协调发展的探索——山西省孝义市柱濮镇农村产业状况剖析

农业是属于社会效益高、比较经济效益低的特殊产业。在社会主义市场经济条件下，如何深化对农业基础地位的认识，按照经济发展的客观规律，科学地指导农业和农村经济持续、快速、健康地发展，尤其是在工矿业发达的地区，如何扭转工业发展、农业萎缩的局面，使工农业相互促进，协调发展，是农业经济工作者研究的一个重要课题。本文分析了孝义市柱濮镇农村产业现状及其农业发展滞后的原因，提出了农村产业协调发展的对策、建议

禽腺病毒贵州分离株ＨＳ—１的核酸酶切分析与蛋白抗原鉴定

本研究利用１０％ＳＤＳ－ＰＡＧＥ及Ｗestern-Blotting技术鉴定３株不同的减蛋综合征病毒（贵州株ＨＳ－１、南京分离毒ＧＣ２、国际标准毒ＡＶ－１２７）的蛋白抗原性，结果表明，３株毒的蛋白多肽分子量均在１０６－１２kＤ范围,一各条多肽的组成上略有差异；它们都具有两条相同的免疫原性多肽，分子量分别为１０６和１００ＫＤ。同时，运用ＥcoRⅠ,HindⅢ，ＰｓｔⅠ和ＳmaⅠ等５种限制性内切酶进行了酶切分析，证实３株ＥＤＳ病毒用ＰstⅠ和ＳmsⅠ酶切的片段大小及长度略有不同，而其它３种酶的酶切图谱完全相同。

陕西韩城褐马鸡分布历史变迁的初步探讨

褐马鸡在陕西韩城黄龙山曾一度被认为已"失踪",1994年再度被"发现".文章通过大量历史资料分析,认为韩城黄龙山林区自古一直有褐马鸡的存在,是褐马鸡的祖居地.并通过黄土高原土地的开拓与利用、森林植被演替史、黄龙山区地貌演化及现代科学研究等,对褐马鸡在陕西韩城分布区历史变迁的原因作了初步探讨.
